1. What are the early signs of hypokalemia on an ECG?

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. In hypokalemia, the T waves may flatten and eventually invert. Elevated ST segments are not typically associated with hypokalemia. Prominent U waves are seen in conditions like hypokalemia, but they are not considered an early sign. A widened QRS complex is more commonly associated with hyperkalemia rather than hypokalemia.

2. What are the expected symptoms of a thrombotic stroke?

Correct answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' In a thrombotic stroke, a clot blocks a cerebral artery, leading to a gradual onset of symptoms such as weakness, numbness, or paralysis on one side of the body. Choice B, 'Sudden loss of consciousness,' is more characteristic of a hemorrhagic stroke. Choice C, 'Severe headache and confusion,' are often associated with subarachnoid hemorrhage rather than thrombotic stroke. Choice D, 'Loss of sensation in the affected limb,' is not a typical symptom pattern for a thrombotic stroke, which usually presents with motor deficits.

3. What dietary changes should be implemented for a patient with GERD?

Correct answer: A

Rationale: The correct answer is A: Avoid mint and spicy foods. Patients with GERD should avoid mint and spicy foods because they can increase gastric acid production, exacerbating symptoms. Choice B is incorrect because eating large meals before bedtime can worsen GERD symptoms due to lying down with a full stomach. Choice C is incorrect as consuming liquids with meals can lead to increased pressure on the lower esophageal sphincter, promoting acid reflux. Choice D is also incorrect as drinking milk as a snack is not recommended for GERD patients, as it may temporarily soothe symptoms but can ultimately stimulate acid production.

4. A nurse is teaching a client about using a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea. Which of the following information should the nurse include in the teaching?

Correct answer: C

Rationale: The correct answer is C because a CPAP device delivers a preset amount of positive airway pressure continuously throughout all inspiration and expiration cycles. Choice A is incorrect because CPAP does not deliver inspiratory pressure at the beginning of each breath; it provides continuous positive pressure. Choice B is incorrect because CPAP typically delivers a constant pressure rather than having a feature that changes pressure throughout the cycle. Choice D is incorrect as CPAP does not deliver positive pressure specifically at the end of each breath; it maintains a consistent pressure throughout the breathing cycle.

5. What are the signs and symptoms of compartment syndrome?

Correct answer: A

Rationale: The signs and symptoms of compartment syndrome include unrelieved pain, pallor, and pulselessness. Unrelieved pain is a key characteristic, indicating tissue ischemia due to increased pressure within a closed anatomic space. Pallor results from compromised blood flow, and pulselessness indicates severe ischemia requiring immediate intervention. Choices B, C, and D are incorrect because localized redness and swelling, fever and infection, and loss of sensation are not specific signs of compartment syndrome. Therefore, the correct answer is A.
