Correct Answer: B

Rationale: Clients with peripheral artery disease often experience claudication (leg pain during walking) due to decreased blood flow. Encouraging rest breaks during walking helps to manage pain and improve circulation. Rest breaks allow the muscles to recover from ischemia caused by inadequate blood supply. Increasing physical activity without breaks may worsen the symptoms. Applying warm compresses can potentially lead to burns or skin damage in individuals with compromised circulation. Massaging the affected leg is contraindicated in peripheral artery disease as it can further compromise blood flow.

Correct Answer: C

Rationale: Severe chest pain is the hallmark symptom of an acute myocardial infarction (heart attack) and requires immediate intervention to prevent further damage to the heart muscle. Chest pain in this context is often described as crushing, pressure, tightness, or heaviness. It can radiate to the arms, neck, jaw, back, or upper abdomen. Other symptoms like dizziness, shortness of breath, nausea, and vomiting may also occur in acute myocardial infarction, but chest pain is the most critical sign requiring prompt action as it signifies inadequate blood flow to the heart muscle. Shortness of breath may indicate heart failure, while nausea and vomiting can be associated with the sympathetic response to myocardial infarction. Dizziness could result from decreased cardiac output but is not as specific to myocardial infarction as severe chest pain.

Correct Answer: D

Rationale: A positive Chvostek's sign suggests hypocalcemia, which is a post-parathyroidectomy complication and requires prompt treatment. The other options are less urgent: being afebrile with a normal pulse is expected, no bowel movement since surgery can be managed with interventions like early ambulation and stool softeners, and no appetite for breakfast is common postoperatively and can be addressed without immediate provider notification.

Correct Answer: B

Rationale: The correct answer is B: 'Take the medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to enhance absorption and effectiveness. The medication is typically taken in the morning before breakfast. Choice A is incorrect because taking levothyroxine with a full meal can decrease its absorption. Choice C is incorrect because bedtime dosing may lead to insomnia. Choice D is incorrect because levothyroxine is a daily medication for hypothyroidism, not to be taken as needed for symptoms.

Correct Answer: D

Rationale: Performing nostril and mouth care is a non-invasive task that can be safely delegated to an unlicensed assistive personnel (UAP). Observing the type and amount of nasogastric tube drainage requires assessment skills and understanding of potential complications, making it more appropriate for a licensed healthcare professional. Monitoring the client for nausea or other complications involves interpreting client responses and identifying adverse reactions, which also requires a licensed healthcare professional. Irrigating the nasogastric tube with the ordered solution involves a procedure that can impact the client's condition and should be performed by a licensed healthcare professional to prevent complications.
