Correct Answer: A

Rationale: Facial flushing is a common symptom of early dumping syndrome, which occurs when food moves too quickly into the small intestine. This rapid movement triggers the release of vasoactive peptides causing vasodilation, leading to facial flushing. Syncope (choice B) is not a typical finding in early dumping syndrome. Diaphoresis (choice C) and bradycardia (choice D) are also not characteristic symptoms of early dumping syndrome.

Correct Answer: A

Rationale: Administering oxygen is the priority intervention for a patient with suspected pulmonary embolism. Maintaining adequate oxygenation is crucial in these patients to prevent hypoxemia and support oxygen delivery to tissues. Administering anticoagulants may be necessary but is not the initial priority. Administering bronchodilators is not indicated for pulmonary embolism. Repositioning the patient does not address the immediate need for oxygenation.

Correct Answer: D

Rationale: The correct method to teach a patient about self-administration of insulin is to use a 90-degree angle for injection. This angle ensures proper subcutaneous administration of insulin, which is essential for effective absorption. Injecting into the upper arm (Choice A) is not recommended for insulin administration. While rotating injection sites (Choice B) is important to prevent lipodystrophy, the angle of injection is crucial for proper insulin delivery. Using a 45-degree angle (Choice C) is more suitable for intramuscular injections, not for subcutaneous insulin injections.

Correct Answer: B

Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods when taking furosemide. Furosemide is a loop diuretic that can cause potassium loss, so consuming potassium-rich foods like bananas and oranges can help maintain adequate potassium levels. Choice A is incorrect because there is no need to avoid consuming dairy products. Choice C is incorrect because while fluid intake may need to be monitored, the general instruction is not to limit fluids to prevent dehydration. Choice D is incorrect because furosemide is usually best taken during the day to avoid disrupting sleep with frequent urination.

Correct Answer: C

Rationale: The correct action the nurse should take for a client at risk for developing DVT is to apply sequential compression devices to the client's legs. This intervention helps prevent venous stasis by promoting circulation and reducing the risk of DVT. Encouraging the client to remain on bed rest (Choice A) can actually increase the risk of DVT due to immobility. Massaging the client's legs every 4 hours (Choice B) can dislodge blood clots and is contraindicated in DVT prevention. While administering anticoagulants as prescribed (Choice D) is a treatment for DVT, it is not a preventive measure for a client at risk.
