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.

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: A

Rationale: In a child who has fallen and hit their head, presenting with drowsiness and headache, the priority action for the nurse is to perform a full neurological assessment. This is crucial to evaluate the extent of the head injury and monitor for signs of increased intracranial pressure, which could indicate a more severe traumatic brain injury. Administering pain medication or allowing the child to rest quietly are not appropriate initial actions without first assessing the neurological status. Checking the child's immunization status is important for overall health but is not the priority in this acute situation.

Correct Answer: D

Rationale: The correct answer is D. Placing the child in a supine position to begin percussion is incorrect for chest physiotherapy (CPT). This position is not effective for CPT as it may lead to improper drainage of secretions. The child should be in an appropriate sitting or slightly reclined position to ensure proper lung drainage during CPT. Choices A, B, and C are all appropriate actions for chest physiotherapy. Performing CPT when the child awakens helps in clearing secretions, using a cupped hand during percussion is a proper technique to promote secretion movement, and administering a bronchodilator before CPT can help open up the airways for better clearance.

Correct Answer: A

Rationale: Corrected Question: The healthcare provider plans to screen only the highest risk children for scoliosis. Which group of children should the healthcare provider screen first? Girls between ages 10 and 14 are at the highest risk for scoliosis and should be screened first as they have a higher incidence of developing scoliosis during their adolescent growth spurt. Early detection and intervention can help prevent further complications associated with scoliosis. Boys between ages 10 and 14 (choice B) are not at the highest risk compared to girls in the same age group. Boys and girls between 12 and 14 (choice C) are at a lower risk compared to girls between ages 10 and 14. Boys and girls between 8 and 12 (choice D) are at a lower risk group compared to girls between ages 10 and 14.
