Preparing Clients for Procedures

Preprocedure Assessment and Patient Safety Foundations

Preparing a client for any intervention begins with a meticulous baseline assessment to prevent injury and set safety standards. Before performing any care, the nurse must verify the client's identity using at least two unique identifiers. Obtaining preprocedure baseline vital signs is essential because these parameters establish an objective reference point for detecting intraoperative and postoperative complications. A baseline neurological and cognitive assessment is equally vital; it identifies preexisting impairments that could compromise the client's ability to understand instructions, participate actively in care, or provide informed consent.

Allergy assessment must be thorough and specific. The nurse assesses for allergies to latex, medications, antiseptics, and contrast media. An important distinction to remember is that a shellfish allergy does not predict an adverse reaction to iodine-containing antiseptics or iodinated contrast. However, true cross-reactivity exists between latex allergy and food sensitivities to bananas, avocados, kiwis, and chestnuts. The nurse also assesses the oral cavity for loose teeth, bridges, caps, and dentures prior to anesthesia to identify risks of dental injury or airway obstruction during intubation. Additionally, assess the possibility of pregnancy and follow facility policy for offering pregnancy testing before anesthesia or procedures involving ionizing radiation when the result could affect care.

Targeted laboratory and physical safety measures complete the initial workup. Laboratory tests are tailored to the client's individual risks and the proposed procedure; these may include a complete blood count, coagulation studies, electrolytes, and blood typing and crossmatching when a blood transfusion is anticipated. For clients at risk of kidney injury, the nurse assesses kidney function using serum creatinine and estimated glomerular filtration rate prior to the administration of intravenous contrast media. The nurse also reviews anticoagulant and antiplatelet therapy before elective procedures, noting that decisions about withholding these medications depend on the balance of bleeding risk, thrombotic risk, and prescriber instructions.

Physical preparation includes infection control and environmental safety. Chlorhexidine gluconate skin cleansing reduces surgical site infections when applied prior to operative procedures. Clients must remove jewelry and body piercings as directed before electrocautery to prevent burns, and they must be screened for implants and have all removable metallic objects removed prior to entering an MRI suite. Finally, encourage clients to void before receiving preprocedure sedatives, when feasible, to reduce the need to ambulate while sedated.
