Correct Answer: A

Rationale: The correct answer is A: 'Avoid alcohol while taking this medication.' Metronidazole can cause a disulfiram-like reaction with alcohol, leading to symptoms like nausea, vomiting, flushing, and headache. Therefore, clients should be instructed to avoid alcohol consumption. Choice B is incorrect because metronidazole is not considered safe during pregnancy, especially in the first trimester. Choice C is incorrect as metronidazole is not known to cause increased appetite. Choice D is also incorrect as hair loss is not a common side effect of metronidazole.

Correct Answer: B

Rationale: The correct teaching point for a client with hearing loss who has been fitted for a hearing aid is to use mild soap and water to clean the ear mold. It is important to keep the ear mold clean to prevent infections and maintain proper functioning. Choice A is incorrect because using the highest setting can lead to discomfort and may not be necessary for all situations. Choice C is incorrect as the hearing aid should generally be turned off when not in use, not just during sleep, to conserve battery life. Choice D is incorrect as immersing the hearing aid in saline solution can damage the device; it should be kept dry to prevent malfunction.

Correct Answer: A

Rationale: The correct answer is A: Liver function tests. Atorvastatin, a medication commonly used to lower cholesterol levels, can potentially cause liver damage as a side effect. Monitoring liver function tests is essential to detect any abnormalities early. Choices B, C, and D are incorrect because atorvastatin is not known to directly impact potassium levels, blood glucose levels, or serum calcium levels. While these parameters may be monitored for other reasons, the priority when administering atorvastatin is to monitor liver function due to the risk of hepatotoxicity.

Correct Answer: C

Rationale: The correct answer is C. QSEN focuses on quality improvement in healthcare. Tracking how soon patients are discharged after different types of surgeries helps in evaluating the quality of care provided and identifying areas for improvement. Choices A and B focus on monitoring outcomes but do not directly relate to quality improvement initiatives. Choice D is more about a routine assessment before discharge and does not involve a quality improvement process.

Correct Answer: B

Rationale: The correct answer is B: Fluid overload. Clients with chronic kidney disease are prone to fluid overload due to impaired kidney function. The kidneys may not effectively regulate fluid balance, leading to fluid retention. Monitoring for signs of fluid overload, such as edema, hypertension, and shortness of breath, is crucial. Choice A, Hypokalemia, is less likely in chronic kidney disease as the kidneys often have difficulty excreting potassium, leading to hyperkalemia. Decreased blood pressure (Choice C) is not a common finding in chronic kidney disease unless complications like volume depletion occur. Increased appetite (Choice D) is not typically associated with chronic kidney disease; in fact, many clients may experience a decreased appetite due to various factors such as uremia and dietary restrictions.
