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: D

Rationale: Severe skin breakdown in the diaper area is significant as it indicates a potential severe issue that needs immediate attention to prevent further complications. Skin breakdown can lead to infections and discomfort for the infant, making it a priority in planning care for this family. The other findings, such as the mother's living situation, baby's irritability during feedings, or formula changes, are important but do not pose immediate risks to the infant's health compared to severe skin breakdown.

Correct Answer: B

Rationale: When screening a 5-year-old for strabismus, directing the child through the six cardinal positions of gaze is the most appropriate action. This method helps the nurse to assess eye alignment, which is crucial in identifying any misalignment that may indicate strabismus. Choices A, C, and D are incorrect. Having the child identify colored patterns on polychromatic cards is more related to visual acuity testing rather than strabismus screening. Inspecting the child for the setting sun sign is not a standard method for strabismus screening. Observing the child for blank, sunken eyes is not specific to strabismus assessment.

Correct Answer: C

Rationale: The correct answer is C: 'Enzymes should be taken before or with meals.' Pancreatic enzymes should be taken before or with meals to assist with digestion in children with cystic fibrosis. This timing helps maximize the effectiveness of the enzymes in breaking down nutrients from food. Giving the enzymes after meals (choice A) may not provide the necessary support for digestion. Mixing the enzymes with hot food or drinks (choice B) is not recommended as it may affect the enzymes' efficacy. Avoiding giving enzymes with any food or drink (choice D) is incorrect as enzymes need to be taken in conjunction with meals to aid in digestion.
