Question 2

A parent reports that her 5-year-old child, who has had all recommended immunizations, had a mild fever 1 week ago, and now has bright red cheeks and a lacy red rash on the trunk and arms. The nurse recognizes that this child might have:
 
  1. Chickenpox (varicella).

Answer to Question 1

A

Feedback
A A lunar month lasts 28 days, or 4 weeks. Pregnancy spans 9 calendar months but 10 lunar months.
B A trimester is one third of a normal pregnancy, or about 13 to 14 weeks.
C The prenatal period covers the full course of pregnancy (prenatal means before birth).
D The EDC is now called the EDB, or estimated date of birth. It has nothing to do with the duration of bed rest.

Answer to Question 2

4
Rationale:
1. Chickenpox (varicella) is unlikely if the child had all recommended immunizations. The rash of varicella progresses from papules to vesicles to pustules.
2. German measles (rubella) is unlikely if the child had all recommended immunizations. The rash of rubella is a pink maculopapular rash that begins on the face and progresses downward to the trunk and extremities.
3. Roseola typically occurs in infants, and begins abruptly with a high fever, followed by a pale pink rash starting on the trunk and spreading to the face, neck, and extremities.
4. Fifth disease manifests first with a flulike illness, followed by a red slapped cheek sign. Then a lacy maculopapular erythematous rash spreads symmetrically from the trunk to the extremities, sparing the soles and palms.
