Correct Answer: A

Rationale: When a child's respirations are slow and shallow due to opioid administration, it results in hypoventilation. This leads to retaining carbon dioxide, indicated by an increased PCO2 level on arterial blood gas analysis, and subsequently causes respiratory acidosis due to the buildup of CO2 in the blood.

Correct Answer: D

Rationale: The correct answer is D: BP of 70/50. When sildenafil (Viagra) is taken with nitroglycerin, it can cause severe hypotension that is unresponsive to treatment. The combination of these medications can lead to a dangerous drop in blood pressure. It is crucial to immediately report hypotension in this scenario. It is recommended to allow at least 24 hours to elapse between the last dose of sildenafil and nitroglycerin to prevent such adverse effects. The other vital signs and lab values may be abnormal but do not have the immediate life-threatening implications that severe hypotension does in this context.

Correct Answer: B

Rationale: Feeding a baby in a more upright position and no longer in sidelying is important around 4-6 months of age. At this stage, babies start developing better head and trunk control, which allows them to sit in a more upright position for feeding, promoting safer and more efficient swallowing and digestion.

Correct Answer: A

Rationale: The most appropriate nursing intervention for a 7-year-old child with acute glomerulonephritis experiencing gross hematuria and bed rest is to provide activities for the child on restricted activity. Although the child may feel well, it is essential to limit activity until hematuria resolves to prevent complications and promote recovery.

Correct Answer: B

Rationale: The correct answer is B. Asking for the child's date of birth is a factual question that does not directly relate to the family's cultural values. The other choices (A, C, D) explore aspects that could provide insights into the family's cultural values and beliefs, such as decision-making dynamics, daily routines, mealtime rules, and views on disability.
