Nursing Elites

1. Which symptoms should the nurse expect a client to exhibit who is diagnosed with a pheochromocytoma?

• A. Numbness, tingling, and cramps in the extremities.
• B. Headache, diaphoresis, and palpitations.
• C. Cyanosis, fever, and classic signs of shock.
• D. Nausea, vomiting, and muscular weakness.

Correct answer: B

Rationale: Correct. Pheochromocytoma is a catecholamine-secreting non-cancerous tumor of the adrenal medulla. The classic triad of symptoms includes headache, diaphoresis (excessive sweating), and palpitations, which result from the overproduction of catecholamines like epinephrine and norepinephrine. Numbness, tingling, and cramps in the extremities (Option A) are not characteristic of pheochromocytoma. Cyanosis, fever, and classic signs of shock (Option C) are not typical symptoms of this condition. Nausea, vomiting, and muscular weakness (Option D) are not commonly associated with pheochromocytoma.

2. A client in the postanesthesia care unit has an as-needed prescription for ondansetron (Zofran). Which of the following occurrences would prompt the nurse to administer this medication to the client?

• A. Paralytic ileus
• B. Incisional pain
• C. Urine retention
• D. Nausea and vomiting

Correct answer: D

Rationale: The correct answer is D: Nausea and vomiting. Ondansetron is an antiemetic used to manage postoperative nausea and vomiting, as well as nausea and vomiting related to chemotherapy. It is not indicated for treating paralytic ileus, incisional pain, or urine retention. Paralytic ileus is a condition of the gastrointestinal tract characterized by the paralysis of intestinal muscles, which would not be treated with ondansetron. Incisional pain is typically managed with analgesics, not antiemetics. Urine retention is a urinary issue that does not involve nausea and vomiting, making ondansetron an inappropriate choice for this condition.

3. A 70-kg adult with chronic renal failure is on a 40-g protein diet. The client has a reduced glomerular filtration rate and is not undergoing dialysis. Which result would give the nurse the most concern?

• A. Albumin level of 2.5 g/dL
• B. Phosphorus level of 5 mg/dL
• C. Sodium level of 135 mmol/L
• D. Potassium level of 5.5 mmol/L

Correct answer: A

Rationale: In chronic renal failure, a protein-restricted diet is crucial to prevent the buildup of waste products. A low albumin level (<3.5 g/dL) indicates inadequate protein intake, raising concern as it may lead to malnutrition and tissue breakdown. Phosphorus, sodium, and potassium levels are not directly impacted by protein intake. Phosphorus levels may elevate in renal failure, but at 5 mg/dL, it is within normal range. Sodium and potassium levels are also within normal limits and not influenced by protein restriction.

4. A client who has just undergone bronchoscopy was returned to the nursing unit 1 hour ago. With which assessment finding is the nurse most concerned?

• A. Oxygen saturation of 97%
• B. Equal breath sounds in both lungs
• C. Absence of cough and gag reflexes
• D. Respiratory rate of 20 breaths/min

Correct answer: C

Rationale: The correct answer is C. The absence of cough and gag reflexes is the most concerning finding for the nurse because it indicates a lack of protective airway reflexes, putting the client at risk of aspiration. Oxygen saturation of 97% is within the normal range and indicates adequate oxygenation. Equal breath sounds in both lungs are a positive finding, indicating no significant abnormalities. A respiratory rate of 20 breaths/min is also within the normal range and does not raise immediate concerns. Therefore, the absence of cough and gag reflexes poses the highest risk to the client's airway safety.

5. During a routine clinic visit, a nurse is assessing a 48-year-old client with a history of smoking. The client, who exercises regularly, reports calf pain during exercise that disappears at rest. Which of the following findings requires further evaluation?

• A. Heart rate of 57 bpm.
• B. SpO2 of 94% on room air.
• C. Blood pressure of 134/82.
• D. Ankle-brachial index of 0.65.

Correct answer: D

Rationale: An Ankle-Brachial Index of 0.65 suggests moderate arterial vascular disease in a client experiencing intermittent claudication, indicating compromised blood flow to the lower extremities during exercise. This finding requires further evaluation to assess the severity of arterial insufficiency and determine appropriate interventions. Choice A (Heart rate of 57 bpm) is within the normal range for an adult at rest and indicates good cardiovascular fitness. Choice B (SpO2 of 94% on room air) is slightly lower than the normal range but is generally acceptable in a healthy individual. Choice C (Blood pressure of 134/82) falls within the normal range and does not raise immediate concerns in this context.
