Correct Answer: D

Rationale: The correct answer is the pulse rate of 115 beats/min. A rapid pulse rate is a sign of compensatory mechanisms in response to dehydration, indicating that the body is trying to deliver oxygen more efficiently. Oxygen therapy may be needed to support the increased oxygen demand. Tenting of skin on the back of the hand is a classic sign of dehydration due to decreased skin turgor. Increased urine osmolarity and weight loss are also indicators of dehydration, but they do not directly suggest a need for oxygen therapy.

Correct Answer: B

Rationale: In this situation, the client's symptoms of congestion and feeling uneasy may indicate an anaphylactic reaction, which can be life-threatening. The most appropriate action is to call the Rapid Response Team to provide immediate assistance and interventions. Elevating the head of the bed, administering diphenhydramine, or slowing the IV infusion rate are not the priority actions in the case of a potential severe allergic reaction. These interventions may delay necessary emergency care and potentially worsen the client's condition.

Correct Answer: B

Rationale: The correct answer is, '"The spirometer will help your lungs expand."?' Incentive spirometry is used postoperatively to help prevent atelectasis by expanding the lungs and improving lung function. Choice A is incorrect because the primary purpose of the spirometer is not to help cough effectively. Choice C is incorrect because while deep breathing with the spirometer can indirectly help prevent blood clots by improving lung function, its primary purpose is not to prevent blood clots directly. Choice D is incorrect because although using the spirometer can improve ventilation and oxygenation, its main purpose is not to improve blood flow in the lungs.

Correct Answer: C

Rationale: The correct answer is 'No indication of renal impairment.' Effective hypertension management aims to prevent complications such as renal impairment. Checking for signs of kidney issues, like abnormal renal function tests, is crucial in monitoring the client's condition. Choices A, B, and D are not specific indicators of effective hypertension management. Pedal edema, sexual dysfunction, and a single blood pressure reading are important but do not solely determine the effectiveness of managing hypertension.

Correct Answer: D

Rationale: The client's selective grooming and washing habits indicate a condition known as 'unawareness of the existence of her left side,' also called hemispatial neglect. This condition is characterized by a lack of awareness or attention to one side of the body or space, typically the left side in stroke patients. Choices A, B, and C are incorrect because the client's actions are not due to poor motor control, paralysis, contractures, or limited visual perception. Instead, they are indicative of a specific cognitive deficit related to neglecting one side of the body.
