Correct Answer: A

Rationale: Obtaining a specimen for blood cultures is crucial in this situation as it helps identify the source of infection, if present, and guide appropriate treatment. This is important in a child with leukemia receiving chemotherapy to prevent potential complications and ensure timely intervention. Assessing the CBC may provide overall information on the child's condition but may not specifically identify a potential infection. Monitoring the oral temperature is important but obtaining blood cultures takes precedence in this scenario. Administering acetaminophen can help reduce fever but does not address the need to identify a possible infection source.

Correct Answer: C

Rationale: Referring the child to the school counselor for educational testing is the most appropriate action in this scenario. This step can help identify the specific learning needs of the student and determine the appropriate interventions required to support his academic success. Option A is not the immediate action needed but may be considered in the future. Option B focuses on homework assistance, which may not address the underlying learning problems. Option D involves consulting the school principal, which is not the primary role in addressing the student's learning needs.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to document the finding. The infant voiding a urinary stream from the ventral surface of the penis suggests hypospadias, a condition where the urethral opening is on the underside of the penis. This finding is crucial information that needs to be documented for further evaluation. Palpating the scrotum for testicular descent, assessing for bladder distension, and auscultating bowel sounds are not appropriate actions based on the presented scenario and do not address the specific concern of the urinary stream location.

Correct Answer: C

Rationale: The correct answer is C. Placing babies on their stomach to sleep increases the risk of sudden infant death syndrome (SIDS). The safest sleep position for infants is on their back to reduce the risk of SIDS. Teaching parents about safe sleep practices is crucial in preventing potential harm to the infant. Choices A, B, and D are all correct statements that promote the well-being of the infant. Feeding the baby in an upright position helps prevent reflux, delaying solid foods until 6 months of age is recommended for proper growth and development, and burping the baby frequently during feedings helps prevent gas buildup and colic.

Correct Answer: A

Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.
