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: B

Rationale: In this scenario, the correct actions for the nurse to take involve ensuring patient safety and fall prevention measures. Choice B is the correct answer because instructing the patient to use the call light allows them to signal for help, applying an ambulation alarm helps detect movement, and checking on the patient hourly increases monitoring frequency. These actions are essential for preventing falls in a disoriented patient with a history of falls. Choices A, C, and D are incorrect: A does not provide adequate monitoring or fall prevention measures, C relies solely on assigning a sitter without utilizing technological aids, and D lacks continuous monitoring and specific fall prevention strategies.

Correct Answer: B

Rationale: The correct answer is B: Peripheral edema. Peripheral edema, the accumulation of fluid causing swelling in the extremities, is a classic sign of heart failure due to fluid overload. This occurs because the heart's reduced pumping efficiency leads to fluid backup in the circulatory system. Choices A, C, and D are incorrect. Decreased heart rate is not typically associated with heart failure; instead, tachycardia or an increased heart rate may be observed. Increased energy levels are not an expected finding in heart failure, as this condition often causes fatigue and weakness. Hyperglycemia is not a direct sign of heart failure; however, it can be present in individuals with uncontrolled diabetes or as a result of certain treatments, but it is not a specific indicator of heart failure.

Correct Answer: A

Rationale: Correct Answer: A nurse should include monitoring for agranulocytosis when educating a patient about clozapine. Clozapine is known to cause agranulocytosis, a potentially life-threatening decrease in white blood cells. This adverse effect requires close monitoring to detect it early. Choices B, C, and D are incorrect because clozapine is not a first-line treatment for most conditions, it is more commonly associated with weight gain rather than weight loss, and it is known to have a risk for metabolic syndrome.

Correct Answer: C

Rationale: The correct answer is C. A history of recurring bowel inflammation can impact the absorption and effectiveness of arthritis medication. Bowel inflammation can affect the body's ability to absorb the medication properly, leading to decreased effectiveness. Choices A, B, and D do not directly relate to the decreased effectiveness of the arthritis medication. Taking medication with water, skipping doses, or taking anti-inflammatory medication without food may not be ideal practices but are not directly linked to the decrease in effectiveness reported by the client.
