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 without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:

• A. 85%
• B. 89%
• C. 95%
• D. 100%

Correct answer: C

Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.

3. What is a priority intervention for a patient experiencing a thyroid storm?

• A. Administering antipyretics.
• B. Cooling the patient.
• C. Administering beta-blockers.
• D. Administering antithyroid medications.

Correct answer: D

Rationale: During a thyroid storm, the priority intervention is to administer antithyroid medications to reduce thyroid hormone levels quickly. These medications, such as propylthiouracil or methimazole, help inhibit the production of thyroid hormones. Administering antipyretics (choice A) may help reduce fever, but it does not address the underlying cause of the thyroid storm. Cooling the patient (choice B) may provide symptomatic relief but does not address the thyroid hormone dysregulation. Administering beta-blockers (choice C) can help manage symptoms like tachycardia and hypertension, but it does not target the root cause of the thyroid storm.

4. The healthcare provider notes a blood pressure of 160/90 mm Hg in a patient taking a thiazide diuretic. The patient reports taking an herbal medication that a friend recommended. Which herbal product is likely, given this patient’s blood pressure?

• A. Ginkgo
• B. Hawthorn
• C. Licorice
• D. St. John’s wort

Correct answer: A

Rationale: The correct answer is A: Ginkgo. Increased blood pressure can result when ginkgo is used in combination with a thiazide diuretic. Option B (Hawthorn) is incorrect because hawthorn is more commonly associated with lowering blood pressure. Option C (Licorice) is incorrect because licorice can lead to sodium and water retention, potentially exacerbating hypertension. Option D (St. John’s wort) is incorrect as it is not typically associated with significant blood pressure effects.

5. A client has been taking oral corticosteroids for the past five days because of seasonal allergies. Which assessment finding is of most concern to the nurse?

• A. White blood count of 10,000/mm³.
• B. Serum glucose of 115 mg/dL.
• C. Purulent sputum.
• D. Excessive hunger.

Correct answer: C

Rationale: The correct answer is C: Purulent sputum. Corticosteroids can suppress the immune system, increasing the risk of infections. Purulent sputum suggests a possible respiratory infection, which can rapidly progress and lead to complications, making it the most concerning finding. Choice A, a white blood count of 10,000/mm³, is within the normal range and not typically a cause for immediate concern. Choice B, a serum glucose level of 115 mg/dL, is also normal and not directly related to corticosteroid use. Choice D, excessive hunger, is a common side effect of corticosteroids but is not as concerning as a sign of infection indicated by purulent sputum.
