Chapter 30 : Pituitary Drugs Questions
Question 1 of 5
When a patient is receiving vasopressin, the nurse will monitor for which therapeutic response?
Correct Answer: D
Rationale: Vasopressin, an antidiuretic hormone, reduces urinary output by promoting water reabsorption in the kidneys, addressing polyuria in conditions like diabetes insipidus. It does not affect appetite, albumin, or potassium levels.
Question 2 of 5
An 8-year-old child has been diagnosed with true pituitary dwarfism and is being treated with somatropin. In follow-up visits, the nurse will monitor for which expected outcome?
Correct Answer: A
Rationale: Somatropin, a growth hormone, is used to treat pituitary dwarfism by promoting increased growth in children. Decreased urinary output and muscle strength are not primary outcomes, and height increase is expected during treatment, not just at puberty.
Question 3 of 5
When reviewing the medication profile of a patient with a new order for desmopressin, the nurse notes that a drug interaction will occur if which drug is taken with desmopressin?
Correct Answer: C
Rationale: Lithium can reduce the therapeutic effect of desmopressin by interfering with its antidiuretic action, potentially worsening polyuria in diabetes insipidus. Aspirin, digoxin, and penicillin do not have significant interactions with desmopressin.
Question 4 of 5
A patient's medication order indicates that he is to receive a dose of cosyntropin. The nurse is aware that this drug is used to diagnose which condition?
Correct Answer: A
Rationale: Cosyntropin is a synthetic ACTH used to diagnose adrenocortical insufficiency by stimulating cortisol production. It is not used for diagnosing diabetes insipidus, myasthenia gravis, or pituitary dwarfism.
Question 5 of 5
A patient who has been on somatropin has been hospitalized for an acute asthma exacerbation, and is receiving intravenous doses of glucocorticoids. The nurse recognizes that which effect may occur if these drugs are given together?
Correct Answer: A
Rationale: Glucocorticoids can reduce the growth-promoting effects of somatropin by counteracting its anabolic actions, though the benefits of glucocorticoids for asthma may outweigh this risk. Hyperkalemia, increased urine output, and diarrhea are not expected interactions.
