A 4-week-old infant is admitted to the emergency room in respiratory distress. Which of the following statements indicates the nurse's knowledge of the anatomy of the respiratory system in pediatric clients?
- A. The diameter of the trachea is much smaller in children than in adults.
- B. The tongue is proportionally smaller in children than in adults.
- C. The pediatric airway is more rigid than that of the adults.
- D. The length of the pediatric airway is longer in children than in adults.
Correct Answer: A
Rationale: The airway in children is much smaller than it is in adults. The diameter of the trachea in the newborn is 4 mm and that of the adult is 20 mm. A small change in the diameter of the airway can make a major difference in the pediatric client. The tongue is proportionally larger in children and fills most of the oral cavity, thereby decreasing air space. The entire pediatric airway is elastic. Elasticity diminishes with age, however. The distances between respiratory structures are shorter than that of adults, and therefore organisms are able to move more rapidly down the throat, leading to more extensive respiratory involvement.
Which finding is expected in the normal newborn?
- A. Epstein pearls
- B. Moro reflex
- C. Swan neck deformity
- D. Cracked pot sound
Correct Answer: B
Rationale: The Moro reflex, a startle response to sudden movement, is a normal finding in newborns, present until about 3-6 months. Epstein pearls are benign but not universal, and the others are abnormal.
The physician has prescribed Zyvox (linezolid) for a patient with VRE. The concurrent use of which medication may result in serotonin syndrome?
- A. Nexium (esomeprazole)
- B. Zoloft (sertraline)
- C. Lipitor (atorvastatin)
- D. Zyrtec (cetirizine)
Correct Answer: B
Rationale: Linezolid, a monoamine oxidase inhibitor, can cause serotonin syndrome when combined with SSRIs like Zoloft (sertraline), due to excessive serotonin accumulation. Nexium, Lipitor, and Zyrtec do not interact in this way.
A 16-year-old female client is admitted to the hospital because she collapsed at home while exercising with videotaped workout instructions. Her mother reports that she has been obsessed with losing weight and staying slim since cheerleader try-outs 6 months ago, when she lost out to two of her best friends.

- A. Obtain an accurate weight
- B. Search the client's purse for pills
- C. Assess vital signs
- D. Assign her to a room with someone her own age
Correct Answer: C
Rationale: Vital signs are a high priority when working with self-destructive clients.
A 19-year-old client fell off a ladder approximately 3 ft to the ground. He did not lose consciousness but was taken to the emergency department by a friend to have a scalp laceration sutured. The nurse instructs the client to:
- A. Clean the sutured laceration twice a day with povidone-iodine (Betadine)
- B. Remove his scalp sutures after 5 days
- C. Return to the hospital immediately if he develops confusion, nausea, or vomiting
- D. Take meperidine 50 mg po q4-6h prn for headache
Correct Answer: C
Rationale: Confusion, nausea, or vomiting may indicate increasing intracranial pressure from a possible head injury, requiring immediate evaluation.
