The nurse knows that children are more susceptible to respiratory tract infections owing to physiological differences. These childhood differences, adverts an adult, include:
- A. Fewer alveoli, slower respiratory rate
- B. Diaphragmatic breathing, larger volume of air
- C. Larger number of alveoli, diaphragmatic breathing
- D. Rounded shape of chest, smaller volume of air
Correct Answer: D
Rationale: Although a child has fewer alveoli than an adult, the child's respiratory rate is faster. Although a child may use diaphragmatic breathing, the adult exchanges a larger volume of air. The adult has a larger number of alveoli than a child. The child's chest is rounded whereas the adult chest is more of an oval shape, and the child does exchange a smaller volume of air than an adult.

The physician has ordered an intravenous infusion of Pitocin for the induction of labor. When assessing the client’s response to the Pitocin, the nurse should give priority to:
- A. Monitoring the blood pressure
- B. Checking the fetal heart rate
- C. Timing the frequency of contractions
- D. Assessing the urinary output
Correct Answer: B
Rationale: Pitocin can cause uterine hyperstimulation, risking fetal distress. Checking the fetal heart rate is the priority to ensure fetal well-being. Blood pressure, contractions, and urinary output are monitored but are secondary to fetal status.
A client with gallstones and obstructive jaundice is experiencing severe itching. The physician has prescribed cholestyramine (Questran). The client asks, “How does this drug work?” What is the nurse’s best response?
- A. “It blocks histamine, reducing the allergic response.”
- B. “It inhibits the enzyme responsible for bile excretion.”
- C. “It decreases the amount of bile in the gallbladder.”
- D. “It binds with bile acids and is excreted in bowel movements with stool.”
Correct Answer: D
Rationale: Cholestyramine binds bile acids in the intestine, forming complexes excreted in stool, reducing circulating bile acids that cause itching. It doesn’t block histamine (A), inhibit enzymes (B), or reduce gallbladder bile (C).
A 65-year-old client is admitted after a stroke. Which nursing intervention would best improve tissue perfusion to prevent skin problems?
- A. Assessing the skin daily for breakdown
- B. Massaging any erythematous areas on the skin
- C. Changing incontinence pads as soon as they become soiled with urine or feces
- D. Performing range-of-motion exercises and turning and repositioning the client
Correct Answer: D
Rationale: Performing range-of-motion exercises and turning/repositioning enhances blood flow to tissues, reducing the risk of pressure ulcers by relieving pressure points. Assessing skin (A) is monitoring, not an intervention to improve perfusion. Massaging erythematous areas (B) can worsen tissue damage. Changing pads (C) prevents irritation but doesn’t directly improve perfusion.
A seventh grader lost consciousness after being hit in the head with a basketball. In the emergency room his vital signs are stable, and he demonstrates no neurologic deficit. He will not be admitted to the hospital. It is most important that you advise his mother to:
- A. Encourage him to drink plenty of fluids
- B. Expect him to have nausea with vomiting
- C. Keep him awake for the next 12 hours
- D. Wake him up every 1-2 hours during the night
Correct Answer: D
Rationale: If the child cannot be awakened from sleep after head injury, it is an indication of serious increase in ICP. The mother should call an ambulance right away.
A client is resting comfortably after delivering her first child. When assessing her pulse rate, the nurse would recognize the following finding to be typical:
- A. Thready pulse
- B. Irregular pulse
- C. Tachycardia
- D. Bradycardia
Correct Answer: D
Rationale: Puerperal bradycardia with rates of 50-70 bpm commonly occurs during the first 6-10 days of the postpartal period. It may be related to decreased cardiac strain, decreased blood volume, contraction of the uterus, and increased stroke volume.
