Correct Answer: B

Rationale: The correct answer is B: Tachycardia. In acute alcohol withdrawal, tachycardia is a common finding due to increased sympathetic activity. Bradycardia (Choice A) is less likely in this condition since the sympathetic nervous system is typically overactive. Hyperthermia (Choice C) is not a typical finding in acute alcohol withdrawal. Hypotension (Choice D) is less common compared to tachycardia in this situation.

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: B

Rationale: Before inserting an indwelling urinary catheter for a female client, the nurse should apply sterile gloves before cleansing the perineal area to prevent infection. Performing perineal care before the procedure is incorrect as it should be done after catheter insertion. Placing the client in a side-lying position is not necessary for this procedure. Lubricating the catheter with petroleum jelly is not recommended as it can damage the catheter; using a water-soluble lubricant is preferred.

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: The correct instruction the nurse should include is to advise the client to avoid consuming foods high in vitamin K. Foods rich in vitamin K, such as leafy greens, can interfere with the effectiveness of warfarin, an anticoagulant medication. Therefore, it is important for clients on warfarin therapy to maintain consistent vitamin K intake to keep their INR levels stable. The other options are also important but not the priority in the context of warfarin therapy. Ingesting foods high in vitamin K can affect the medication's efficacy, making it crucial to highlight this dietary consideration during client education.
