HESI Fundamental Practice Exam

Correct Answer: A

Rationale: To infuse 1,000 mL over 10 hr, the IV pump should be set to deliver 100 mL/hr. This calculation is derived by dividing the total volume (1,000 mL) by the total time in hours (10 hr), resulting in the infusion rate of 100 mL/hr. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation for this scenario.

Correct Answer: A

Rationale: Placing the wheelchair at a 45-degree angle to the bed is the correct technique for transferring a client who is unable to walk from bed to a wheelchair. This positioning facilitates a safer and easier transfer by providing more space for maneuvering and reducing the distance the client needs to be moved. Positioning the wheelchair parallel to the bed (Choice B) may make the transfer more challenging due to limited space and a longer distance to move the client. Placing the wheelchair in front of the bed (Choice C) may not provide an optimal angle for the transfer. Having the client stand and pivot into the wheelchair (Choice D) is not appropriate for a client who is unable to walk and could increase the risk of falls or injuries during the transfer.

Correct Answer: B

Rationale: The correct answer is B. The recent administration of opioid analgesics increases the risk for falls due to potential side effects such as sedation and dizziness. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk for falls. Choice C, stooped posture with an unsteady gait, may indicate an existing risk but does not directly reflect the need to include 'Risk for falls' in the care plan. Choice D, expressed feelings of depression, is important to address but is not directly associated with the risk for falls.

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: C

Rationale: The correct answer is C: 'I should use a soft-bristled toothbrush while taking this medication.' Using a soft-bristled toothbrush is crucial as it helps prevent bleeding gums, which is a potential side effect of warfarin therapy. Option A about taking warfarin at the same time every day is a good practice but does not directly relate to preventing side effects. Option B suggesting an increase in green leafy vegetables can interfere with warfarin's anticoagulant effects due to their vitamin K content. Option D advising to avoid alcohol is generally recommended but is not directly related to the specific side effects of warfarin.
