HESI Fundamentals Study Guide

Correct Answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

Correct Answer: C

Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.

Correct Answer: A

Rationale: The nurse's priority in this situation is to determine the reason why the client is refusing to use the incentive spirometer. By understanding the client's concerns or barriers, the nurse can address them effectively and encourage the client to use the spirometer for optimal postoperative recovery. Insisting that the client use the spirometer without understanding the underlying reason may lead to further resistance. Administering pain medication as a solution does not address the root cause of refusal and may not be necessary if pain is not the primary reason for refusal. Documenting the refusal is important but should come after understanding the client's perspective to provide appropriate care and follow-up.

Correct Answer: A

Rationale: The correct instruction for a client prescribed alendronate (Fosamax) is to take the medication with a full glass of water. Alendronate can cause irritation to the esophagus, so it is important to take it with a full glass of water and remain upright for at least 30 minutes after taking the medication to help prevent this irritation. Taking the medication at bedtime (choice B) may increase the risk of esophageal irritation as lying down can allow the medication to remain in the esophagus longer. Taking the medication with food (choice C) or on an empty stomach (choice D) can also interfere with the absorption of alendronate, reducing its effectiveness in treating osteoporosis.

Correct Answer: D

Rationale: In a closed wound drainage system, it is essential to maintain the drain in a dependent position to allow for proper drainage. Gravity aids in the flow of drainage, preventing fluid backflow or pooling. Avoiding pressing the container down to create a vacuum (Choice A) is crucial as it can lead to complications in the system. Wearing sterile gloves (Choice B) is important for infection control when handling the drainage system. Resetting the container with the drainage port closed (Choice C) is incorrect as it can cause spillage and contamination of the surrounding area.
