[frankwu]

The antiemetic drug ondansetron (Zofran) is being administered to a child receiving chemotherapy. It should be administered:
 
  1. Only if the child experiences nausea.
   2. After the chemotherapy has been administered.
   3. Before chemotherapy administration, as a prophylactic measure.
   4. Never; this antiemetic is not effective for controlling nausea and vomiting associated with chemotherapy.

Question 2

A parent reports that her five-year-old child, who has had all recommended immunizations, had a mild fever one week ago and now has bright red cheeks and a lacy red maculopapular rash on the trunk and arms.
 
  The nurse recognizes that this child might have: 1. Rubeola (measles).
  2. German measles (rubella).
  3. Chickenpox (varicella).
  4. Fifth disease (erythema infectiosum).

Answer to Question 1

3
Rationale:
1. Giving it after the child has nausea or at the end of chemotherapy treatment does not help with preventing nausea.
2. Giving it after the child has nausea or at the end of chemotherapy treatment does not help with preventing nausea.
3. The antiemetic ondansetron (Zofran) should be administered before chemotherapy, and every four hours during the administration of chemotherapy, as a prophylactic measure.
4. It is the drug of choice for controlling nausea caused by chemotherapy agents.

Answer to Question 2

4
Rationale 1: Children with rubeola have a high temperature and a blotchy maculopapular rash. Because there is a vaccination for rubeola, it is unlikely the child has it.
Rationale 2: The rash of rubella is a pink, maculopapular rash that begins on the face and progresses downward to the trunk and extremities. The child is fully vaccinated, making this unlikely.
Rationale 3: Varicella (chickenpox) and rubella (German measles) are unlikely if the child has had all recommended immunizations.
Rationale 4: Fifth disease manifests first with a flu-like 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.
