Correct Answer: D

Rationale: Option D is the most appropriate response as it acknowledges the client's expressed uncertainty about the surgery. By acknowledging the client's feelings, the nurse validates their concerns and opens the door for further discussion. This approach can help build trust and rapport with the client. Option A focuses more on seeking justification for the client's belief rather than addressing the underlying emotion. Option B, while acknowledging doubt, does not directly address the client's feelings. Option C, although well-intentioned, dismisses the client's concerns without exploring them further.

Correct Answer: B

Rationale: Clear fluid draining from the ear can indicate cerebrospinal fluid leakage, which is a serious concern after a head injury. This leakage can signify a skull fracture or damage to the meninges, potentially leading to infection. Therefore, it should be reported immediately for further evaluation and management. Choices A, C, and D are typical findings after head trauma and are not as urgent as the presence of clear fluid draining from the ear.

Correct Answer: B

Rationale: The most important point to emphasize when teaching a client with diabetes about insulin administration is to administer insulin before meals as prescribed. This is crucial for maintaining proper blood sugar control throughout the day. Choice A is incorrect because blood sugar levels need to be monitored multiple times a day, not just once in the morning. Choice C is incorrect because insulin should be administered according to the prescribed schedule, not only when feeling unwell. Choice D is incorrect because blood sugar monitoring should be done at various times during the day, not just in the evening.

Correct Answer: A

Rationale: Corrected Rationale: Dehydration in the elderly is often signaled by dry mouth, confusion, and decreased skin turgor due to reduced fluid intake. Choice A is the correct answer as these are common signs and symptoms of dehydration in the elderly.\nIncorrect Rationales: Option B (Increased heart rate and muscle cramps) are more associated with conditions like hyperthyroidism or electrolyte imbalances rather than dehydration. Option C (Fever, rapid breathing, and increased urine output) are signs of other medical conditions such as infections or diabetes insipidus. Option D (Increased thirst and difficulty walking) can be seen in various situations but are not specific signs of dehydration in the elderly.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor the client's weight daily.' In clients with heart failure on fluid restriction, monitoring daily weight is crucial to track fluid balance. This allows healthcare providers to assess if the client is retaining excess fluid, a common issue in heart failure. Choices A, C, and D are incorrect. Encouraging the client to drink more water contradicts the fluid restriction; avoiding drinking water after 6 PM is not specific to managing fluid restriction; and monitoring fluid intake only during meals does not provide a comprehensive assessment of fluid balance throughout the day.
