Chapter 30 Questions
Question 1 of 5
The nurse notes in a patient's medication history that the patient has been taking desmopressin. Based on this finding, the nurse interprets that the patient has which disorder?
Correct Answer: B
Rationale: Desmopressin, a synthetic antidiuretic hormone, is used to treat diabetes insipidus by reducing excessive thirst and urination caused by deficient endogenous antidiuretic hormone. It is not indicated for diabetes mellitus, adrenocortical insufficiency, or carcinoid tumors.
Question 2 of 5
A 16-year-old boy who is taking somatropin comes into the office because he had an asthma attack during a race at school. Because of this new development, the nurse expects which intervention to occur next?
Correct Answer: C
Rationale: Somatropin should be used cautiously in patients with acute or chronic illnesses like asthma, often requiring dosage adjustments to balance risks and benefits. Immediate discontinuation is not necessary, and growth monitoring is routine but not the primary intervention.
Question 3 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 4 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 5 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.
