When assessing a 5-year-old male child suspected of having acute myeloid leukemia (AML), the nurse practitioner should expect:

Rationale:
A. Herpes simplex in infants typically presents with painful vesicles and sometimes systemic symptoms, not a persistent whitish coating.
B. Oral candidiasis (thrush) presents as a white, curd-like coating on the tongue, gums, or inner cheeks that cannot be wiped away. It is caused by an overgrowth of Candida species and is common in young infants.
C. A normal coating in infants (milk residue) is easily wiped away and does not persist.
D. Poor oral care may cause debris or plaque later in infancy but is not the cause of persistent white plaques in young infants.

Rationale:
A. Withdrawal from physical activity such as track is not necessary for a healthy, uncomplicated pregnancy; regular exercise is encouraged.
B. Limiting sexual intercourse is not routinely required in a normal pregnancy unless there are complications.
C. Avoiding undercooked steaks and other undercooked meats is important to reduce the risk of foodborne infections, particularly Toxoplasma gondii and other pathogens, which can be harmful to the developing fetus.
D. Weight gain should not be limited to 15 pounds; recommendations vary based on pre-pregnancy BMI, and restricting weight gain unnecessarily may be harmful.
