HESI Nutrition Exam

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia increases the risk of dysrhythmias when taking digoxin, making potassium intake crucial. Digoxin toxicity is more likely in patients with low potassium levels, leading to an increased risk of dysrhythmias. Choices B, C, and D are incorrect because hypokalemia in combination with digoxin is primarily associated with dysrhythmias rather than oliguria, irritability, anxiety, or alteration of consciousness.

Correct Answer: D

Rationale: Assisting with oral hygiene is the essential initial step before collecting a sputum specimen for acid-fast bacillus (AFB) to prevent contamination of the sample. Ensuring the client's mouth is clean reduces the risk of introducing unwanted bacteria into the specimen. Asking the client to cough sputum into a container, having the client take deep breaths, and providing a specimen container are important steps in the specimen collection process, but they should follow ensuring proper oral hygiene.

Correct Answer: A

Rationale: The most important instruction for a 65-year-old female client diagnosed with osteoporosis regarding exercise is to engage in weight-bearing activities. Weight-bearing exercises are crucial in maintaining bone density and preventing osteoporosis-related fractures. Choice B is incorrect because the primary focus should be on bone health rather than weight reduction. Choice C is incorrect as avoiding all exercise activities that increase the risk of fracture would limit physical activity, which is essential for overall health. Choice D is incorrect as while strengthening muscles is beneficial, weight-bearing activities directly impact bone health in osteoporosis.

Correct Answer: C

Rationale: When a client is receiving intravenous antibiotics, checking the IV site for signs of phlebitis is a priority assessment for the nurse. Phlebitis is an inflammation of the vein, which can lead to serious complications such as infection and thrombosis. Monitoring the IV site helps prevent these complications and ensures the safe delivery of antibiotics. While monitoring the client's temperature, pain level, and respiratory status are important assessments, they are not the priority in this scenario where IV antibiotic administration requires close monitoring for complications like phlebitis.

Correct Answer: D

Rationale: For a client with a percutaneous endoscopic gastrostomy (PEG) tube, flushing the tube adequately with water before and after use is essential. This action helps prevent clogging and ensures the proper administration of feedings and medications. Choice A is incorrect because pulverizing all medications into a powdery condition is not necessary for PEG tube administration. Choice B is incorrect as squeezing the tube to break up stagnant liquids may damage the tube. Choice C is incorrect because cleansing the skin around the tube daily with hydrogen peroxide can be too harsh and lead to skin irritation.
