Extract:
Question 1 of 5
A child with croup is placed in a cool, high-humidity tent connected to room air. The primary purpose of the high-humidity tent is to:
Correct Answer: D
Rationale: High-humidity tents in croup moisten airways, liquefying secretions and relieving laryngeal spasms, easing breathing. Oxygen levels are not necessarily 30%, and dehydration or fever is secondary.
Question 2 of 5
Which one of the following statements is correct when measuring the client for crutches?
Correct Answer: B
Rationale: Proper crutch fitting requires a gap of about three inches (or two to three fingerbreadths) between the crutch top and the axilla to prevent nerve damage. The elbow should flex at about 30°, and crutches extend about 6 inches laterally from the foot.
Question 3 of 5
The nurse is caring for a client with a history of anaphylaxis to peanuts. Which precaution is most important?
Correct Answer: A
Rationale: An epinephrine auto-injector is critical for immediate treatment of anaphylaxis, a life-threatening allergic reaction. Private rooms, antihistamines, and monitoring are secondary to ensuring rapid emergency response.
Question 4 of 5
Which medication does the nurse expect to be ordered for the postpartal patient with bleeding uncontrolled by Pitocin (oxytocin)?
Correct Answer: A
Rationale: Methergine is used to treat postpartum hemorrhage unresponsive to Pitocin by promoting uterine contractions. Aquamephyton is for clotting, Amicar is for fibrinolysis, and Celestone is a corticosteroid, none of which address uterine bleeding.
