A nurse is caring for a client with a pheochromocytoma. Which assessment finding will the nurse expect for this client?
Decreased pulse
Elevated blood pressure
Cold intolerance
Decreased respiratory rate
The Correct Answer is B
Rationale:
A. A decreased pulse is not typically associated with pheochromocytoma. This condition is characterized by the excessive release of catecholamines, which usually leads to an increased heart rate.
B. Pheochromocytoma is a tumor of the adrenal medulla that causes excessive secretion of catecholamines, leading to episodic or sustained hypertension. Elevated blood pressure is a hallmark symptom of this condition.
C. Cold intolerance is more commonly associated with hypothyroidism and is not a typical finding in pheochromocytoma.
D. Decreased respiratory rate is not characteristic of pheochromocytoma; instead, clients may experience symptoms such as palpitations, sweating, and headaches due to the elevated catecholamine levels.

Correct Answer is ["A","B","C","E"]
Explanation
Rationale:
A. A decreased level of consciousness is a common symptom of ARF due to hypoxemia, which reduces oxygen delivery to the brain, leading to confusion, agitation, or lethargy.
B. Hypercarbia, or elevated levels of carbon dioxide (CO2) in the blood, occurs due to impaired gas exchange in ARF, which leads to respiratory acidosis.
C. Severe dyspnea, or difficulty breathing, is a hallmark symptom of ARF as the lungs fail to maintain adequate oxygenation or ventilation.
D. Nausea is not a typical manifestation of ARF; while it may occur due to other factors, it is not directly associated with respiratory failure.
E. Tachycardia, or an increased heart rate, is often seen in ARF as the body attempts to compensate for hypoxemia by increasing cardiac output to deliver more oxygen to tissues.
Correct Answer is C
Explanation
Rationale:
A. Hypernatremia, an elevated sodium level, does not cause Trousseau's or Chvostek's signs.
B. Hypermagnesemia, an elevated magnesium level, is not associated with positive Trousseau's and Chvostek's signs.
C. Hypocalcemia, a low calcium level, is commonly associated with positive Trousseau's and Chvostek's signs. Trousseau's sign is a carpopedal spasm induced by inflating a blood pressure cuff, while Chvostek's sign is facial twitching in response to tapping over the facial nerve. Both are indicative of neuromuscular irritability due to low calcium levels.
D. Hypokalemia, a low potassium level, does not cause these specific signs and is associated with different clinical manifestations.
