Correct Answer: C

Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.

Correct Answer: B

Rationale: The correct answer is B: To maintain straight spinal alignment. Logrolling is a technique used to carefully turn a client while keeping the spine in a straight line, especially important for those with spinal injuries or after back surgery. Choice A is incorrect because the primary purpose is not specifically to decrease the risk of back injury but to ensure safe turning. Choice C is incorrect as the main aim is not to increase client safety by using multiple people but to protect the spine. Choice D is incorrect because the primary purpose of logrolling is not to prevent skin damage but to safeguard the spine during turning.

Correct Answer: C

Rationale: The correct teaching for a client with COPD prescribed home oxygen therapy is to educate them on how to clean and replace the oxygen tubing. This is crucial to prevent infections and ensure the effectiveness of the oxygen delivery system. Option A is not necessary as oxygen therapy is usually prescribed as needed, not continuously at night. While smoking cessation and avoiding smoke exposure are important in COPD management, it is not directly related to home oxygen therapy. Increasing fluid intake is beneficial for some conditions but is not specifically related to home oxygen therapy for COPD.

Correct Answer: C

Rationale: Assisting the client to stand by the side of the bed to void is the most appropriate action in this situation. Standing to void often helps relieve the bladder, especially after surgery. Option A, having him drink several glasses of water, may not be as effective as the client might already be adequately hydrated. Option B, Crede maneuver, is a technique for emptying the bladder by applying manual pressure and is not the first-line intervention for a client who cannot void post-surgery. Option D, waiting 2 hours before trying to void again, may delay necessary intervention if the client is experiencing urinary retention.

Correct Answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are more susceptible to lead poisoning from environmental sources due to their behaviors like hand-to-mouth contact and exploratory behaviors. Choices A, C, and D are less likely to be at high risk for lead poisoning compared to young children due to differences in exposure levels and behaviors related to potential sources of lead contamination.
