Question 1 of 25Medium
A technician notes that two different strengths of the same injectable medication have almost identical packaging and color schemes from the manufacturer. Which of the following is the most appropriate proactive safety step?
- A. Combine the different strengths into a single bin to save shelf space
- B. Decant the vials into amber prescription bottles with handwritten labels
- C. Alert the pharmacist and place auxiliary warning labels on the product bins
- D. Return all inventory of both strengths to the wholesaler immediately
Show answer to question 1
Answer: C. Alert the pharmacist and place auxiliary warning labels on the product bins
When manufacturers produce look-alike packaging, pharmacy personnel should alert the pharmacist, separate the items, and apply visual warnings such as auxiliary labels or shelf talkers. Decanting sterile injectables into amber prescription vials compromises sterility and is unsafe.
Question 2 of 25Medium
A pharmacy technician is stocking a medication that requires special safeguards due to high risk of significant harm if used in error. Which medication is considered a high-alert medication by the ISMP?
- A. Heparin 10,000 units/mL injection
- B. Amoxicillin 250 mg capsules
- C. Multivitamin tablets
- D. Acetaminophen 500 mg tablets
Show answer to question 2
Answer: A. Heparin 10,000 units/mL injection
Heparin is on ISMP's high-alert list because errors in dose or concentration can cause life-threatening bleeding. High-concentration vials such as 10,000 units/mL have been confused with much weaker strengths, so special safeguards are used.
Why the other options are wrong
- BAmoxicillin capsules are a routine antibiotic with a wide margin of safety.
- CMultivitamin tablets carry little risk of serious harm from an error.
- DAcetaminophen 500 mg tablets are a routine OTC analgesic, not a high-alert drug.
Question 3 of 25Medium
When a customer arrives at the retail pharmacy drive-thru to pick up a prescription, which technique should the pharmacy technician use to best verify the patient identity?
- A. State the patient date of birth and ask the driver to verify the corresponding spelling of the last name
- B. Read the patient name and address from the prescription bag and ask the driver to confirm with yes or no
- C. Ask open-ended questions such as requesting the patient state their full name and date of birth
- D. Ask the driver if they are picking up a prescription for the name displayed on the computer screen
Show answer to question 3
Answer: C. Ask open-ended questions such as requesting the patient state their full name and date of birth
Asking open-ended questions requires the customer to provide specific information without prompting, which prevents wrong-patient dispensing errors. Asking closed-ended questions that only require a yes or no confirmation increases the risk of medication release to the wrong person due to misunderstanding or passive agreement.
Question 4 of 25Easy
A pharmacy technician discovers an incorrect strength of metoprolol in a prescription vial before handing it to the patient at checkout. What is the most appropriate action for the technician to take regarding quality assurance?
- A. Contact the prescriber immediately to request an altered prescription for the incorrect strength.
- B. Quietly exchange the medication for the correct strength without documenting the event.
- C. Place the incorrect vial back into the stock inventory and restart the entire dispensing process.
- D. Log the event as a near miss and notify the pharmacist to investigate the discrepancy.
Show answer to question 4
Answer: D. Log the event as a near miss and notify the pharmacist to investigate the discrepancy.
Logging a near miss and informing the pharmacist allows the pharmacy team to identify workflow vulnerabilities before harm reaches a patient. Quietly exchanging the medication without documentation bypasses quality improvement processes and prevents the pharmacy from addressing system weaknesses that caused the error.
Question 5 of 25Medium
Which pair of drug names is commonly confused and uses tall man lettering to reduce medication errors?
- A. metformin and metoprolol
- B. warfarin and enoxaparin
- C. amoxicillin and ampicillin
- D. hydroXYzine and hydrALAzine
Show answer to question 5
Answer: D. hydroXYzine and hydrALAzine
Hydroxyzine and hydralazine are look-alike sound-alike (LASA) drugs. Tall man lettering (e.g., hydroXYzine vs hydrALAzine) highlights the differing letters to prevent confusion.
Why the other options are wrong
- AMetformin and metoprolol are not commonly confused as they have different prefixes and suffixes.
- BWarfarin and enoxaparin are both anticoagulants but are not typically considered LASA pairs requiring tall man lettering.
- CAmoxicillin and ampicillin are similar but are not typically distinguished with tall man lettering; they are often differentiated by other means.
Question 6 of 25Easy
A pharmacy technician observes that the automated dispensing cabinet displays predniSONE and prednisoLONE with selective capitalization. According to the Institute for Safe Medication Practices (ISMP), what is the primary purpose of this formatting?
- A. Signaling that the products require reconstitution before dispensing
- B. Distinguishing between look-alike and sound-alike drug names
- C. Directing staff to store the medications in high-security vaults
- D. Indicating that the medications are designated as controlled substances
Show answer to question 6
Answer: B. Distinguishing between look-alike and sound-alike drug names
Tall Man lettering highlights the differences between look-alike and sound-alike (LASA) drug names to draw attention to dissimilar syllables and prevent medication selection errors. It does not designate controlled substance status, special security storage requirements, or preparation techniques like reconstitution.
Question 7 of 25Medium
Healthcare providers are encouraged to report which of the following events to the Vaccine Adverse Event Reporting System (VAERS)?
- A. Only fatal reactions that have been confirmed by laboratory findings
- B. Only mild injection-site soreness lasting fewer than twenty-four hours
- C. Any clinically significant adverse event, even if causation is uncertain
- D. Expected mild side effects that are already fully detailed in the vaccine package insert
Show answer to question 7
Answer: C. Any clinically significant adverse event, even if causation is uncertain
Healthcare providers should report any clinically significant adverse event that occurs after vaccination, even if they are unsure whether the vaccine caused the event. Limiting reports strictly to fatal, laboratory-confirmed reactions would prevent the system from detecting emerging safety trends early. Mild, expected reactions like temporary injection-site tenderness generally do not warrant a VAERS report unless they become severe or unexpected.
Question 8 of 25Hard
A pharmacy experiences chronic understaffing and excessive prescription volume, creating conditions where technicians rush through tasks and mislabel an oral antibiotic. In root cause analysis, how is the chronic understaffing classified?
- A. Active human failure
- B. Intentional technician violation
- C. Latent system failure
- D. Inevitable clinical risk
Show answer to question 8
Answer: C. Latent system failure
Latent system failures are underlying organizational defects, such as inadequate staffing or poor scheduling, that remain dormant until they align to cause an active error. Active human failures are the direct mistakes made by frontline practitioners at the point of task execution, such as the mislabeling itself, rather than the organizational pressures that facilitated it.
Question 9 of 25Hard
A pharmacy technician is stocking the automated dispensing cabinet and notices two vials labeled 'DOPamine' and 'Dobutamine'. The pharmacy uses a specific labeling technique to help differentiate these easily confused drug names. What is this technique called?
- A. Bar code verification
- B. Tall man lettering
- C. Color-coded labeling
- D. Expiration date highlighting
Show answer to question 9
Answer: B. Tall man lettering
Tall man lettering uses uppercase letters to emphasize the differences in look-alike, sound-alike drug names (e.g., DOPamine vs. DOBUTamine). This is a recommended error-prevention strategy by the Institute for Safe Medication Practices (ISMP).
Why the other options are wrong
- ABar code verification is a scanning process to confirm the correct drug, not a labeling technique.
- CColor coding is not standardized and can lead to confusion; tall man lettering is the specific technique described.
- DExpiration date highlighting is unrelated to differentiating drug names.
Question 10 of 25Medium
A pharmacy technician is cleaning the compounding area in an ISO Class 5 environment. According to USP <797>, which of the following cleaning agents should be used on surfaces?
- A. Quaternary ammonium compound followed by sterile alcohol
- B. Sterile water
- C. Sodium hypochlorite (bleach) diluted
- D. Isopropyl alcohol 70% only
Show answer to question 10
Answer: A. Quaternary ammonium compound followed by sterile alcohol
USP 797 requires a two-step disinfection process: first a detergent (e.g., quaternary ammonium compound) to remove organic matter, then a sterile 70% isopropyl alcohol to disinfect. This ensures proper cleaning of the cleanroom.
Why the other options are wrong
- BSterile water does not have disinfectant properties and is not used for cleaning surfaces.
- CBleach is not recommended for routine use in ISO Class 5 environments due to residue and potential damage to surfaces.
- DAlcohol alone is insufficient for initial cleaning; it does not remove soil or bioburden effectively.
Question 11 of 25Easy
Which of the following prescriptions is written correctly to avoid medication errors involving decimals?
- A. Levothyroxine 25.0 mg
- B. Levothyroxine .25 mg
- C. Levothyroxine 0.250 mg
- D. Levothyroxine 0.25 mg
Show answer to question 11
Answer: D. Levothyroxine 0.25 mg
A dose smaller than 1 needs a leading zero, and a trailing zero must never follow a decimal point (ISMP and The Joint Commission). Writing 0.25 mg follows both rules, so the decimal point cannot be missed or misread.
Why the other options are wrong
- AIncluding a trailing zero after a whole number (25.0 mg) can be misinterpreted as 250 mg if the decimal is overlooked.
- BOmitting the leading zero (writing .25 mg) can lead to misreading as 25 mg, a 100-fold overdose.
- CIncluding a trailing zero (0.250 mg) can cause confusion; the decimal may be missed, leading to a 250 mg dose.
Question 12 of 25Medium
Which of the following is a recommended strategy from the Institute for Safe Medication Practices (ISMP) to reduce errors with look-alike sound-alike (LASA) medications?
- A. Use only generic names on all labels
- B. Use tall man lettering on labels and shelf tags
- C. Place LASA drugs in the same bin to save space
- D. Store LASA drugs in alphabetical order next to each other
Show answer to question 12
Answer: B. Use tall man lettering on labels and shelf tags
Tall man lettering (e.g., DOBUTamine vs. DOPamine) highlights the differences in drug names, reducing the chance of misreading. ISMP recommends this as a key strategy for LASA drugs. Other strategies include separating them in storage and using both brand and generic names.
Why the other options are wrong
- AUsing only generic names can actually increase confusion for LASA drugs because many generic names look alike; including brand names can help differentiate.
- CPlacing LASA drugs in the same bin increases the likelihood of grabbing the wrong drug; they should be separated to avoid confusion.
- DStoring LASA drugs alphabetically next to each other increases the risk of selection errors because they are physically close and have similar names.
Question 13 of 25Medium
A pharmacy technician receives a prescription for 'hydrALAzine' but the prescriber's handwriting is unclear. The technician should be aware that hydrALAzine is often confused with which of the following drugs?
- A. hydrOXYzine
- B. hydrochlorothiazide
- C. hydrocortisone
- D. hydrocodone
Show answer to question 13
Answer: A. hydrOXYzine
HydrALAzine (an antihypertensive) and hydrOXYzine (an antihistamine) are look-alike sound-alike drugs. Tall man lettering helps differentiate them. The technician should verify the indication and use auxiliary labels if needed.
Why the other options are wrong
- BHydrochlorothiazide is a diuretic, but its name is not as visually or phonetically similar to hydrALAzine as hydrOXYzine is.
- CHydrocortisone is a corticosteroid, and its name is not typically confused with hydrALAzine.
- DHydrocodone is an opioid, and its name is less similar to hydrALAzine.
Question 14 of 25Hard
Which system design feature is specifically engineered to prevent the accidental connection of enteral feeding tubes to intravenous administration lines?
- A. Universal needleless injection ports
- B. Color-coded piggyback stopcocks
- C. Standardized Luer-slip connectors
- D. ENFit connector systems
Show answer to question 14
Answer: D. ENFit connector systems
ENFit connectors are engineered to a specific ISO standard for enteral devices that makes them physically incompatible with standard Luer connectors found on intravenous lines. Standard Luer-slip connectors and universal injection ports actually increase the hazard of route mix-ups by allowing incompatible lines to mate. Color-coding provides a visual cue but is not a physical engineering barrier.
Question 15 of 25Medium
A pharmacy technician discovers a medication error where a patient received the wrong dose of a high-alert drug. The technician reports the error through the facility's internal reporting system. What is the primary goal of this error reporting?
- A. To identify system weaknesses and prevent future errors
- B. To discipline the staff member involved
- C. To notify the patient's prescriber immediately
- D. To document the error for insurance claims
Show answer to question 15
Answer: A. To identify system weaknesses and prevent future errors
Error reporting systems are designed to identify root causes and system failures so that processes can be improved to prevent recurrence. The focus is on learning and improvement, not punishment.
Why the other options are wrong
- BDiscipline is not the goal; error reporting aims to improve systems, not to blame individuals.
- CNotifying the prescriber is a clinical step, but the reporting system's purpose is to analyze and prevent future errors.
- DInsurance claims are a separate process; the primary goal of error reporting is safety improvement.
Question 16 of 25Medium
A pharmacy technician realizes that a patient was given the wrong medication due to a dispensing error. What is the technician's first priority according to best practices?
- A. Place the incorrect medication in the return bin
- B. Complete an incident report form
- C. Contact the patient to apologize
- D. Immediately inform the supervising pharmacist
Show answer to question 16
Answer: D. Immediately inform the supervising pharmacist
The first priority in any medication error is patient safety. The technician must immediately notify the pharmacist, who can assess the situation and take appropriate action (e.g., contacting the patient, arranging correction). Prompt reporting prevents further harm and allows for timely intervention.
Why the other options are wrong
- APlacing the medication in the return bin is not appropriate before the error is reported; the incorrect medication may need to be retained for investigation or returned to inventory properly.
- BCompleting an incident report is important for documentation and quality improvement, but it should be done after the pharmacist is notified and the immediate patient safety issue is addressed.
- CContacting the patient is typically the pharmacist's responsibility, and the technician should not do so without direction; the pharmacist will decide how to communicate with the patient.
Question 17 of 25Hard
A pharmacy technician is verifying a filled prescription for a high-alert medication. According to best practices for medication error prevention, which of the following steps is most critical before dispensing?
- A. Confirm the patient's name and date of birth using two identifiers
- B. Check the expiration date on the bottle
- C. Ensure the label is printed in a font size of at least 12 points
- D. Perform an independent double-check of the medication against the original order
Show answer to question 17
Answer: D. Perform an independent double-check of the medication against the original order
An independent double-check (two individuals separately verify the medication, dose, and patient against the order) is a key safety measure for high-alert drugs to catch potential errors before dispensing. This is recommended by ISMP and many accreditation bodies.
Why the other options are wrong
- APatient identification is essential but is typically done before verification; the double-check focuses on the medication itself.
- BChecking expiration is important but not the most critical step for preventing medication errors in high-alert drugs.
- CFont size is not a standard requirement for error prevention; legibility is important but not the most critical step.
Question 18 of 25Easy
During a routine monthly inventory inspection, a pharmacy technician identifies stock bottles of an oral antihypertensive medication that passed their expiration date last week. Which action must the technician take immediately?
- A. Return the opened medication containers directly to the original drug manufacturer.
- B. Move the bottles to a designated, segregated area away from active dispensing stock.
- C. Mark the bottles with clearance labels and keep them on the shelf for discount dispensing.
- D. Dispose of the medication immediately in the pharmacy sink with copious running water.
Show answer to question 18
Answer: B. Move the bottles to a designated, segregated area away from active dispensing stock.
Expired medications must be immediately removed from active inventory and placed into a clearly marked quarantine or segregated area to prevent accidental dispensing. Pouring pharmaceuticals down the drain violates environmental safety guidelines, and expired drugs may never be discounted or dispensed.
Question 19 of 25Hard
Which shared boxed warning applies to systemic nonsteroidal anti-inflammatory drugs (NSAIDs) such as meloxicam, diclofenac, and celecoxib?
- A. Severe cutaneous adverse reactions with HLA-B*5701 positivity
- B. Progressive multifocal leukoencephalopathy and severe neutropenia
- C. Serious cardiovascular thrombotic events and gastrointestinal bleeding
- D. Lactic acidosis and fatal hypothermia in renal impairment
Show answer to question 19
Answer: C. Serious cardiovascular thrombotic events and gastrointestinal bleeding
Systemic NSAIDs carry boxed warnings for an increased risk of serious, potentially fatal cardiovascular thrombotic events (such as myocardial infarction and stroke) and severe gastrointestinal bleeding, ulceration, and perforation. Lactic acidosis in renal failure is the signature boxed warning of metformin. Progressive multifocal leukoencephalopathy is linked to specific biologic immunomodulators, while HLA-B*5701 testing is required before starting the antiretroviral abacavir.
Question 20 of 25Hard
A pharmacy technician is compounding a hazardous drug solution that requires a final concentration of 5 mg/mL. The technician needs to prepare 100 mL of the solution using a stock solution of 25 mg/mL. According to USP <800>, which of the following is the correct volume of stock solution to use, and what additional safety step must be taken?
- A. 20 mL of stock solution, and wear a single pair of gloves
- B. 20 mL of stock solution, and compound in a Class II BSC
- C. 5 mL of stock solution, and compound in a cleanroom
- D. 5 mL of stock solution, and use a syringe without a needle
Show answer to question 20
Answer: B. 20 mL of stock solution, and compound in a Class II BSC
Using C1V1 = C2V2: 25 mg/mL × V1 = 5 mg/mL × 100 mL → V1 = 20 mL. USP <800> requires compounding hazardous drugs in a Class II biological safety cabinet (BSC).
Why the other options are wrong
- ACompounding a hazardous drug requires two pairs of chemotherapy gloves, so a single pair is not enough.
- CVolume is incorrect (5 mL yields 125 mg total, concentration would be 1.25 mg/mL, not 5 mg/mL).
- DVolume is incorrect, and a syringe without a needle is not a safety measure for hazardous drugs.
Question 21 of 25Easy
A pharmacy technician is entering a prescription for warfarin 2.5 mg. Which of the following is the correct way to write the strength to prevent a medication error?
- A. 2.5 mg
- B. .5 mg
- C. 2.50 mg
- D. 2.5mg
Show answer to question 21
Answer: A. 2.5 mg
The correct format is '2.5 mg' without a trailing zero (2.50) or leading zero missing (.5). A trailing zero (2.50) can be misread as 250 if the decimal is missed, and a leading zero missing (.5) can be misread as 5. The space between the number and unit is standard to avoid confusion.
Why the other options are wrong
- B.5 mg lacks a leading zero, which could be misread as 5 mg if the decimal point is missed.
- C2.50 mg has a trailing zero, which could be misread as 250 mg if the decimal point is overlooked.
- D2.5mg lacks a space between the number and unit, which can lead to misinterpretation, though less critical than decimal errors.
Question 22 of 25Hard
Which of the following is considered a high-alert medication that requires special safeguards to reduce the risk of errors?
- A. Acetaminophen
- B. Insulin
- C. Ibuprofen
- D. Diphenhydramine
Show answer to question 22
Answer: B. Insulin
Insulin is on the ISMP high-alert medication list due to the high risk of severe hypoglycemia from dosing errors. Acetaminophen, ibuprofen, and diphenhydramine are common OTC drugs not classified as high-alert, though acetaminophen has toxicity concerns.
Why the other options are wrong
- AAcetaminophen is not on the high-alert list; while overdose can cause liver damage, it does not require the same level of safeguards as insulin.
- CIbuprofen is an NSAID available OTC and not considered a high-alert medication.
- DDiphenhydramine is an antihistamine, not classified as high-alert.
Question 23 of 25Easy
A patient picking up a refill for lisinopril reports developing a persistent, nonproductive dry cough. The pharmacy technician should recognize this symptom as which of the following?
- A. An indication of a sudden severe drug allergy
- B. A life-threatening anaphylactic reaction
- C. A known class-related adverse drug effect
- D. A symptom of acute systemic medication toxicity
Show answer to question 23
Answer: C. A known class-related adverse drug effect
A dry, persistent cough is a well-documented class-related adverse effect of ACE inhibitors, caused by the accumulation of bradykinin in the upper respiratory tract. It represents a benign, nonallergic side effect rather than anaphylaxis or a life-threatening allergic reaction. While uncomfortable for the patient, it does not indicate acute systemic drug toxicity.
Question 24 of 25Easy
A pharmacy technician is labeling a new stock bottle of a medication that is frequently confused with another drug. Which pair of drug names is most likely to require tall man lettering to prevent dispensing errors?
- A. DOBUTamine and DOPamine
- B. metformin and metoprolol
- C. amoxicillin and ampicillin
- D. ibuprofen and naproxen
Show answer to question 24
Answer: A. DOBUTamine and DOPamine
Tall man lettering uses uppercase letters to highlight differences in look-alike sound-alike (LASA) drug names. DOBUTamine and DOPamine are classic examples because they differ only by a few letters and are often confused. This technique reduces the risk of dispensing errors.
Why the other options are wrong
- Bmetformin and metoprolol belong to different drug classes and are not considered a high-risk LASA pair; they are less likely to be confused.
- Camoxicillin and ampicillin are similar but are not typically listed as high-risk LASA pairs requiring tall man lettering; they are more commonly differentiated by other means.
- Dibuprofen and naproxen are both NSAIDs but have distinct names and are not a common source of confusion requiring tall man lettering.
Question 25 of 25Medium
According to USP <797>, what is the minimum ISO classification required for the buffer room where primary engineering controls (PECs) for sterile compounding are located?
- A. ISO Class 9
- B. ISO Class 7
- C. ISO Class 8
- D. ISO Class 5
Show answer to question 25
Answer: B. ISO Class 7
USP <797> requires the buffer room (where the PEC is placed) to be at least ISO Class 7. The PEC itself (e.g., laminar airflow workbench) must be ISO Class 5. The ante room must be at least ISO Class 8.
Why the other options are wrong
- AISO Class 9 is roughly ordinary room air and is not used for any USP <797> compounding area.
- CISO Class 8 is the minimum for the ante room, not the buffer room.
- DISO Class 5 is the requirement for the primary engineering control (PEC), not the buffer room.
