Correct Answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

Correct Answer: A

Rationale: Checking for skin turgor is a reliable method to assess dehydration in patients. Skin turgor refers to the skin's elasticity and hydration status. When a healthcare professional gently pinches the skin on the back of the patient's hand or forearm, dehydration is indicated by the skin not snapping back immediately. Monitoring blood pressure (choice B) is important but is more indicative of cardiovascular status rather than dehydration specifically. Checking for dry mucous membranes (choice C) can be a sign of dehydration, but skin turgor is a more direct assessment. Monitoring urine output (choice D) is also essential but may not provide immediate feedback on hydration status as skin turgor does.

Correct Answer: B

Rationale: The correct answer is to monitor the client's respiratory rate. This assessment is crucial in the postoperative period to detect any respiratory complications such as hypoxia or respiratory distress. Assessing pain level (Choice A) is important but may not be the top priority as respiratory status takes precedence. Measuring blood pressure (Choice C) is also important but not as critical immediately postoperatively as monitoring respiratory function. Checking bowel sounds (Choice D) is relevant for assessing gastrointestinal function but is typically not the top priority in the immediate postoperative phase.

Correct Answer: A

Rationale: Administering oxygen is the initial intervention for a patient experiencing breathing difficulties post-surgery. Providing oxygen helps improve oxygenation and alleviate respiratory distress. Repositioning the patient, checking oxygen saturation, and elevating the head of the bed are important interventions but administering oxygen takes precedence in addressing hypoxia and respiratory compromise.

Correct Answer: C

Rationale: The correct intervention for a client with dementia who is frequently agitated is to use a calm and reassuring approach when speaking to them. This approach helps reduce agitation and create a more therapeutic environment. Offering several choices may overwhelm the client and increase agitation, making choice A incorrect. Confronting the client can escalate the situation and worsen agitation, making choice B inappropriate. While encouraging stimulating activities is beneficial, it may not be the most effective intervention for immediate agitation management, making choice D less priority compared to using a calm and reassuring approach.
