Correct Answer: B

Rationale: The most appropriate intervention for a patient with a suspected stroke is to perform a CT scan. A CT scan is crucial for diagnosing a stroke by visualizing any bleeding or blockages in the brain. Administering IV fluids (Choice A) may be necessary based on the patient's condition, but it is not the primary intervention for a suspected stroke. Performing a lumbar puncture (Choice C) is not indicated for stroke evaluation and may not provide relevant information. Administering anticoagulants (Choice D) is a treatment option for certain types of strokes but should be based on the CT scan results and specific guidelines.

Correct Answer: D

Rationale: The correct answer is D: Apply sequential compression devices to the client's legs. Sequential compression devices help prevent venous stasis and reduce the risk of DVT by promoting blood flow in the legs. Massaging the client's legs every 2 hours (choice A) may dislodge a clot if present, leading to a higher risk of embolism. Instructing the client to sit with the legs crossed (choice B) can impede blood flow and increase the risk of DVT. Administering prophylactic antibiotics (choice C) is not indicated for preventing DVT, as antibiotics are used to treat infections caused by bacteria, not to prevent blood clots.

Correct Answer: C

Rationale: The correct intervention for a client with deep vein thrombosis (DVT) is to elevate the affected extremity above the level of the heart. This position promotes venous return, reduces swelling, and helps prevent complications such as pulmonary embolism. Applying cold compresses (choice A) can vasoconstrict blood vessels, potentially worsening the condition. Massaging the affected extremity (choice B) can dislodge the clot and lead to serious complications. Keeping the affected extremity dependent when sitting (choice D) can hinder venous return and exacerbate the DVT.

Correct Answer: A

Rationale: The correct instruction for managing heartburn during pregnancy is to eat small, frequent meals. This helps prevent heartburn by reducing gastric distention. Option B, drinking a glass of milk with each meal, may exacerbate heartburn in some individuals due to its fat content. Option C, lying down after meals, can worsen heartburn as it allows stomach acid to flow back into the esophagus. Option D, drinking plenty of fluids with meals, can also contribute to heartburn by distending the stomach. Therefore, the best advice for managing heartburn during pregnancy is to eat small, frequent meals.

Correct Answer: C

Rationale: The correct answer is C: Teach the client pursed-lip breathing technique. Pursed-lip breathing helps clients with COPD improve oxygenation and reduce shortness of breath. Choice A is incorrect because deep breathing and coughing are not recommended every 4 hours for clients with COPD. Choice B is incorrect because a diet high in carbohydrates and low in protein is not specifically indicated for COPD. Choice D is incorrect because fluid restriction is not a standard intervention for COPD unless the client has comorbid conditions that necessitate it.
