HESI Fundamental Practice Exam

Correct Answer: A

Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.

Correct Answer: C

Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.

Correct Answer: A

Rationale: The correct technique for transferring a client from a bed to a chair to avoid back injuries is to bend at the knees while maintaining a wide stance and a straight back. This position ensures that the nurse uses leg muscles rather than the back muscles for lifting, reducing the risk of injury. Placing the client's hands on the nurse's shoulders and the nurse's hands under the client's axillae provides additional support and stability during the transfer. Using a mechanical lift may be appropriate for certain situations but is not necessary for a simple bed-to-chair transfer. Twisting at the waist while holding the client can lead to back strain or injury. Asking for assistance from another staff member is a good practice, but proper body mechanics should still be followed to ensure safe client handling.

Correct Answer: B

Rationale: When documenting client care, it is crucial to use standardized abbreviations to ensure clear communication and prevent misunderstandings. BRP for bathroom privileges is a recognized and commonly used abbreviation in healthcare settings. Choice A, SS for sliding scale, is not a standard abbreviation and can lead to confusion as it could be mistaken for other meanings. Choice C, OJ for orange juice, is informal and may not be universally understood in a healthcare context. Choice D, SQ for subcutaneous, is a valid abbreviation but may not be as relevant in the context of documenting client care compared to BRP, which is more specific and widely accepted.

Correct Answer: B

Rationale: Using a sterile technique throughout the procedure is essential to prevent infection when inserting an IV catheter. This includes maintaining aseptic conditions, using sterile equipment, and following proper hand hygiene practices. Choice A is incorrect because threading the catheter up to the hub does not specifically address infection prevention. Choice C is incorrect as cleaning the insertion site with alcohol only may not provide adequate disinfection, as it is essential to use an antiseptic solution to reduce microbial load. Choice D is incorrect as wearing gloves alone is not sufficient protection against infection; a mask should also be worn to prevent the spread of microorganisms through respiratory secretions.
