Of the following, the BEST therapeutic approach for this infant is
- A. chemotherapy
- B. radiotherapy
- C. concomitant chemo-radiotherapy
- D. chemotherapy followed by radiotherapy
Correct Answer: A
Rationale: Complete resection with microscopic residual disease typically warrants adjuvant chemotherapy.

The parents of a 3-month-old infant report that their infant sleeps supine (face up) but is often prone (face down) while awake. What knowledge should the nurse's response should be based?
- A. Unacceptable because of the risk of sudden infant death syndrome (SIDS)
- B. Unacceptable because it does not encourage achievement of developmental milestones
- C. Acceptable to encourage fine motor development
- D. Acceptable to encourage head control and turning over
Correct Answer: D
Rationale: The correct knowledge that the nurse's response should be based on is that it is acceptable to encourage head control and turning over. At 3 months of age, encouraging the infant to be prone while awake can help promote the development of head control, neck strength, and eventually facilitate the ability to turn over. This practice is considered safe and beneficial for infants within the appropriate age range, as long as the infant is supervised during the awake period. It is important to promote safe sleep practices for infants to reduce the risk of Sudden Infant Death Syndrome (SIDS), but allowing supervised tummy time for an awake infant is beneficial for their motor development.
A 10 years old girl presented with fever and bruises for last 2 weeks. On examination she is pale; however there is no evidence of lymphadenopathy or hepatosplenomegaly. Her Hb is 6g/dl, TLC is 2700 and platelets are 90000. The most appropriate investigation to clinch the diagnosis is:
- A. Bone marrow aspiration
- B. Retics count
- C. Bleeding time
- D. PT and APTT
Correct Answer: A
Rationale: Bone marrow aspiration is essential to rule out conditions like aplastic anemia or leukemia, which could explain the symptoms and lab findings.

Vitamin A supplementation may be recommended for the young child who has which disease?
- A. Mumps
- B. Rubella
- C. Measles (rubeola)
- D. Erythema infectiosum
Correct Answer: C
Rationale: Vitamin A supplementation may be recommended for children with measles (rubeola) due to the disease's association with vitamin A deficiency. Measles can lead to reduced levels of vitamin A in the body, which can result in increased severity of symptoms, complications, and even death. Supplementing with vitamin A during and after a measles infection helps reduce the risk of complications and mortality, particularly in young children under the age of 5 in areas where vitamin A deficiency is common. Therefore, providing vitamin A supplementation to children with measles is an important intervention to support their recovery and improve outcomes.
