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 to assess the pulse and blood pressure. Distended neck veins can indicate fluid volume overload or heart failure, which can lead to hemodynamic instability. Assessing the pulse and blood pressure will provide immediate information on the client's cardiovascular status. Documenting the observation in the chart (choice A) is important but not the priority when immediate assessment is needed. Measuring urine specific gravity and volume (choice B) is important for assessing renal function but is not the priority in this situation. Assessing the client's deep tendon reflexes (choice D) is not relevant to addressing distended neck veins in a client sitting to eat.

Correct Answer: A

Rationale: The correct answer is 'Airborne.' Varicella (chickenpox) is caused by the varicella-zoster virus, which spreads through the air by respiratory droplets. Therefore, placing the client on airborne precautions is necessary to prevent the transmission of the virus. Choice B, 'Standard precautions,' involve basic infection prevention measures that are used for all client care. Choice C, 'Contact precautions,' are used for diseases that spread by direct or indirect contact. Choice D, 'Droplet precautions,' are implemented for diseases transmitted by respiratory droplets that are larger than 5 microns.

Correct Answer: D

Rationale: The correct answer is to teach the client lifestyle modifications to decrease blood pressure. A blood pressure reading of 134/88 mm Hg falls within the prehypertension range. The initial approach to managing prehypertension involves lifestyle modifications such as dietary changes, exercise, and stress reduction techniques. Calling the healthcare provider without attempting non-pharmacological interventions first is premature. Reassessing blood pressure at the next follow-up appointment may delay necessary interventions. Administering additional antihypertensive medication is not indicated at this stage as lifestyle modifications are the first line of treatment for prehypertension.

Correct Answer: D

Rationale: The correct action for the nurse to take when a client finds antiembolism stockings uncomfortably tight is to teach the client the purpose of wearing the stockings. This educates the client on the importance of the stockings in preventing blood clots and encourages compliance. Removing the stockings or pulling them down may compromise their effectiveness. Measuring the client's calf size is not necessary in this situation as the discomfort is due to tightness, not incorrect sizing.
