What is the most important nursing intervention for a patient with a suspected pulmonary embolism?

Correct Answer: A

Rationale: The most important nursing intervention for a patient with a suspected pulmonary embolism is to administer anticoagulants. Anticoagulants help prevent further clot formation in the patient's blood vessels, reducing the risk of complications such as worsening of the pulmonary embolism or development of new clots. Administering oxygen (Choice B) may be necessary to support the patient's oxygenation, but anticoagulants take precedence as they target the underlying cause of the pulmonary embolism. Repositioning the patient (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of patient care but are not the primary intervention for a suspected pulmonary embolism.

Correct Answer: A

Rationale: The best position for a patient with respiratory distress is the Semi-Fowler's position. This position promotes lung expansion and improves oxygenation by allowing the chest to expand more fully. The Trendelenburg position, where the patient's feet are higher than the head, is contraindicated in respiratory distress as it can increase pressure on the diaphragm and compromise breathing. The prone position, lying face down, may be beneficial in certain cases like acute respiratory distress syndrome but is not generally recommended for all patients in respiratory distress. The supine position, lying flat on the back, can worsen respiratory distress by causing the tongue to fall back and obstruct the airway.

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: 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.

Correct Answer: A

Rationale: The correct answer is to administer anticoagulants. Administering anticoagulants is crucial in the management of deep vein thrombosis (DVT) as it helps prevent the clot from growing larger or dislodging, potentially causing a life-threatening pulmonary embolism. While monitoring oxygen levels, applying compression stockings, and encouraging ambulation are important aspects of DVT management, administering anticoagulants is the most critical intervention to prevent further complications.

Correct Answer: A

Rationale: Corrected Rationale: Monitoring daily weight is the most accurate method to assess fluid balance in patients receiving diuretics. Changes in weight reflect changes in fluid balance, making it a sensitive indicator. Monitoring intake and output (choice B) is important but may not provide a complete picture of overall fluid balance. Checking for edema (choice C) is a late sign of fluid imbalance and may not be sensitive enough to detect subtle changes. Monitoring blood pressure (choice D) is relevant but may not directly reflect fluid balance as it can be influenced by various other factors.

Correct Answer: A

Rationale: In this scenario, the client is experiencing frequent contractions with a short duration and an elevated fetal heart rate, indicating potential fetal distress. Discontinuing the oxytocin infusion is crucial to prevent further complications and restore normal fetal parameters. Increasing or maintaining the oxytocin infusion could exacerbate the situation, leading to more distress for the fetus. Decreasing the oxytocin infusion may not be sufficient to address the current issue and could delay the improvement of fetal well-being.

Correct Answer: D

Rationale: A WBC count of 15,000/mm³ is elevated and may indicate infection, which should be reported. High WBC count is a sign of inflammation or infection, and in a postoperative client, it can be indicative of surgical site infection or another complication. Urinary output, serosanguineous wound drainage, and a heart rate of 94/min are all within normal ranges for a client post cholecystectomy and do not raise immediate concerns for infection or complications.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.
