The nurse assessing a client hospitalized with a diagnosis of hypoparathyroidism notes positive Trousseau's and Chvostek's signs. The nurse determines that these findings most indicate which electrolyte imbalance?
Hypernatremia
Hypermagnesemia
Hypocalcemia
Hypokalemia
The Correct Answer is C
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.

Correct Answer is D
Explanation
Rationale:
A. Hypertension can be a symptom of many conditions and is not specific to HHS.
B. Fruity breath is typically associated with diabetic ketoacidosis (DKA) due to the presence of acetone, not HHS.
C. Ketosis is a key feature of DKA, not HHS. In HHS, ketosis is usually absent or minimal.
D. A glucose level of 650 mg/dL is indicative of HHS, which is characterized by extremely high blood glucose levels without significant ketosis. HHS often occurs in type 2 diabetes and is marked by severe hyperglycemia, dehydration, and altered mental status.
Correct Answer is B
Explanation
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.
