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 A
Explanation
Rationale:
A. Desmopressin is a synthetic analog of antidiuretic hormone (ADH) and is used to reduce urine output in conditions like diabetes insipidus. Monitoring urine output is the primary way to assess the effectiveness of this medication. A decrease in urine volume indicates the medication is working effectively.
B. Pupillary response is not relevant in assessing the effectiveness of desmopressin.
C. Temperature monitoring is important in general patient care but does not directly relate to the effectiveness of desmopressin.
D. Apical heart rate is important to monitor in many scenarios but is not a direct indicator of desmopressin's effectiveness.
Correct Answer is D
Explanation
Rationale:
A. Fluid intake may need to be monitored, but restricting fluids is not typically advised unless specifically directed by the healthcare provider due to complications like diabetes insipidus.
B. Avoiding deep breathing exercises is not recommended, as these exercises are important for preventing respiratory complications postoperatively.
C. Lying flat for 48 hours after surgery is incorrect; the head of the bed is usually elevated to decrease intracranial pressure and promote healing.
D. Avoiding blowing the nose and bending at the waist is crucial after transsphenoidal hypophysectomy to prevent increased intracranial pressure and avoid disrupting the surgical site, which could lead to complications such as cerebrospinal fluid leakage.
