Practice HESI Fundamentals Exam

Correct Answer: A

Rationale: The correct answer is A. Rolling the NPH vial between the hands before drawing it up ensures proper mixing of the insulin. Choice B is incorrect because regular insulin should be drawn up first to avoid contamination. Choice C is incorrect as injecting air into the vial of regular insulin is not necessary. Choice D is incorrect as there is no need to wait 10 minutes after mixing the insulin before injecting it.

Correct Answer: B

Rationale: The correct instruction to include in the teaching plan for a client who had a hemiarthroplasty of the left hip is to 'Place a pillow between your knees while lying in bed to prevent hip dislocation.' This technique helps maintain proper hip alignment and prevents dislocation during the postoperative recovery period. Choice A is incorrect because bending at the waist to reach items on the floor can strain the hip joint and is not recommended following hip surgery. Choice C is incorrect because using a walker alone without assistance can increase the risk of falls and injury, especially in the immediate postoperative period. Choice D is incorrect because pain medication should be taken as prescribed by the healthcare provider, not specifically timed after physical therapy sessions.

Correct Answer: C

Rationale: In this scenario, when the client is unconscious and unable to make decisions, a notarized original of advance directives brought in by the partner should be given priority to guide the direction of care. Advance directives provide legal documentation of the client's wishes regarding healthcare decisions in situations where they cannot express their preferences. The statement of client rights and the client self-determination act (Choice A) outlines general principles but does not provide specific guidance on the client's care. Orders written by the healthcare provider (Choice B) are important but may not reflect the client's preferences. Clinical pathway protocols (Choice D) are useful for standard care pathways but do not address individual client wishes.

Correct Answer: A

Rationale: The correct answer is to use the complete name of the medication magnesium sulfate. This is important to prevent confusion with morphine sulfate, which is abbreviated as MSO4. Choice B is incorrect as it is essential to maintain a space between the numerical dose and the unit of measure for clarity in medication documentation. Choice C is incorrect as the standard abbreviation for units is 'U' for international units, not for the dosage of insulin. Choice D is incorrect as the appropriate abbreviation for subcutaneous injection is 'SC,' not just 'SC.' Therefore, the nurse manager should emphasize using the full name of medications to avoid errors and ensure patient safety.

Correct Answer: A

Rationale: Hanging the collection bag below the level of the bladder is the correct technique for maintaining proper drainage and preventing backflow in a client with an indwelling urinary catheter. Therefore, choice A is the correct answer as it indicates a need for further teaching. Choices B, C, and D demonstrate appropriate actions in catheter care. Performing hand hygiene before handling the catheter helps prevent infection, securing the catheter to the client's leg with tape prevents accidental dislodgement, and emptying the collection bag when it is full ensures that the catheter functions effectively.
