A nurse in a pediatric clinic is teaching a newly hired nurse about the varicella zoster virus. Which of the following information should the nurse include in the teaching?
Children who have varicella should be placed in droplet precautions.
Children who have varicella can have aspirin if experiencing discomfort.
Children who have varicella should receive the herpes zoster vaccine.
Children who have varicella are contagious until vesicles are crusted.
The Correct Answer is D
A. Varicella (chickenpox) requires airborne and contact precautions, not droplet precautions, due to its high transmissibility.
B. Aspirin should never be given to children with viral infections because it increases the risk of Reye’s syndrome, a life-threatening condition causing liver failure and encephalopathy.
C. The herpes zoster vaccine (Zostavax or Shingrix) is for adults to prevent shingles, not for children with active varicella infection.
D. Children with varicella are contagious from 1–2 days before the rash appears until all vesicles have crusted over (usually 5–7 days). They should be isolated from susceptible individuals during this period.

Correct Answer is ["A","C","D"]
Explanation
Rationale:
A. Closing the door helps contain radiation and protect staff and visitors from exposure.
B. A semi-private room is contraindicated; the client must be in a private room to protect others from radiation exposure.
C. Wearing a lead apron during direct care reduces exposure to scatter radiation. The nurse should also avoid standing directly at the radiation source.
D. Limiting visitors to 30 minutes per day minimizes radiation exposure time. The principle of "time, distance, and shielding" guides radiation safety.
E. Pregnant visitors should not enter the client’s room at all, as fetal tissue is highly sensitive to radiation.
Correct Answer is C
Explanation
Rationale:
A. The client is doing 30 min of moderate exercise daily: Regular moderate exercise (e.g., walking, swimming) is recommended in pregnancy. It improves circulation, mood, and endurance for labor.
B. The client last visited the dentist 4 months ago: Dental care is encouraged during pregnancy because hormonal changes increase the risk of gingivitis. A dental visit 4 months ago is appropriate.
C. The client started working in a parking garage 3 months ago: Parking garages have poor ventilation and potential exposure to carbon monoxide (CO) from car exhaust, which can cause fetal hypoxia and developmental harm. The nurse should assess environmental safety and possibly recommend reassignment.
D. The client is drinking 2.5 L of water per day: Adequate hydration is essential in pregnancy to maintain amniotic fluid volume and prevent dehydration.
