Question 1 of 5
A client with a diagnosis of diabetes insipidus asks the nurse about the purpose of the vasopressin she has been prescribed. The nurse responds, knowing that this medication promotes which action?
Correct Answer: C
Rationale: Vasopressin is a vasopressor and an antidiuretic. It directly stimulates contraction of smooth muscle, causes vasoconstriction, stimulates peristalsis, and increases reabsorption of water by the renal tubules, resulting in decreased urinary output.
Question 2 of 5
The nurse evaluates a client's knowledge as deficient when the client makes which of the following statements about the drug dexamethasone (Decadron)?
Correct Answer: B
Rationale: Dexamethasone requires consistent dosing, and missing a dose can have significant effects, indicating a need for further instruction.
Question 3 of 5
A 6-month-old has had a pyloromyotomy to correct a pyloric stenosis. Three days after surgery, the parents have placed their infant in his own infant seat (see fi gure). The nurse should do which of the following?
Correct Answer: D
Rationale: Following pyloromyotomy the infant should be positioned with the head elevated and slightly on the right side to promote gastric emptying; the parents have positioned their infant correctly. The infant should be positioned on the right side, not the left side. When the child is in a crib, the head can be elevated and the infant can be propped on the right side. The infant can use a pacifi er if needed.
