Correct Answer: C

Rationale: The correct instruction for a client with a new prescription for nitroglycerin sublingual tablets is to take one tablet every 5 minutes, up to three doses, for chest pain. This dosing regimen helps relieve chest pain associated with angina by promoting vasodilation. Option A is incorrect as nitroglycerin sublingual tablets should be placed under the tongue, not swallowed with water. Option B is incorrect because taking nitroglycerin with food may decrease its effectiveness. Option D is incorrect because nitroglycerin sublingual tablets are meant to be dissolved under the tongue, not swallowed whole.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Administering anticoagulants is the most appropriate nursing intervention for a patient with suspected DVT because it helps prevent further clot formation and complications. Applying compression stockings (choice B) can be a preventive measure but is not the primary intervention for treating DVT. Encouraging ambulation (choice C) is beneficial for preventing DVT but is not the immediate intervention for a suspected case. Monitoring oxygen saturation (choice D) is important for assessing respiratory function but is not the primary intervention for DVT treatment.

Correct Answer: B

Rationale: The correct answer is to limit fluid intake for a patient with chronic kidney disease. This restriction helps manage fluid balance to prevent fluid overload. Choices A, C, and D are incorrect. Limiting potassium intake is essential for some patients with kidney disease, but it is not the primary dietary restriction. Increasing protein intake is usually not recommended due to the impaired kidney function in these patients. Increasing carbohydrate intake is also not a standard recommendation for patients with chronic kidney disease.

Correct Answer: C

Rationale: In a mass casualty situation, a client with hypovolemic shock should be the priority as they require immediate intervention to restore fluid volume and prevent further deterioration. Hypovolemic shock can lead to organ failure and death if not addressed promptly. While clients with other severe conditions like massive head trauma, full-thickness burns, or an open fracture also need urgent care, hypovolemic shock directly threatens the client's life due to inadequate circulating blood volume. Therefore, stabilizing the client with indications of hypovolemic shock takes precedence over others in this scenario.

Correct Answer: A

Rationale: The correct action for the nurse to take when caring for a client with COPD is to encourage the client to increase physical activity. Increased physical activity helps manage COPD symptoms by improving lung function and preventing deconditioning. Placing the client in the Trendelenburg position is not recommended for COPD as it can worsen breathing difficulties. Limiting fluid intake to prevent fluid overload is not typically necessary in COPD unless the client has comorbid conditions that require fluid restriction. Administering high-flow oxygen via mask may be necessary for COPD clients with severe hypoxemia, but it is not the initial action for planning care.
