Correct Answer: D

Rationale: The correct answer is D: Elevated creatinine phosphokinase (CPK). Elevated CPK levels indicate muscle damage, including damage to the cardiac muscle, which aligns with the diagnosis of myocardial infarction. Choice A, low serum albumin, is not directly related to myocardial infarction. Choice B, high serum cholesterol, is more associated with conditions like atherosclerosis rather than acute myocardial infarction. Choice C, abnormally low white blood cell count, is typically not a lab value associated with myocardial infarction; instead, it could suggest other conditions like infections or bone marrow issues.

Correct Answer: A

Rationale: In some Hispanic cultures, touching the baby after looking at them is believed to prevent the 'evil eye.' Respecting this cultural belief can help build trust and comfort with the client. Choices B, C, and D are incorrect as they do not address the specific cultural concern raised by the client. Talking slowly or avoiding touching the child does not relate to the belief in the 'evil eye.' Similarly, focusing only on the parents does not address the client's worry about the newborn receiving the 'evil eye.'

Correct Answer: C

Rationale: The correct answer is C because wound care for a postoperative infection is a skilled service that qualifies for Medicare reimbursement. Choices A, B, and D involve assessments, teaching, and evaluation, which may not meet the criteria for Medicare reimbursement as they do not directly involve a skilled nursing service related to a postoperative condition.

Correct Answer: C

Rationale: The correct answer is C, 'Prolonged hypoxemia.' Prolonged hypoxemia is a critical condition that requires specialized pediatric care due to the high risk of cardiac arrest. The other choices, such as congenital cardiac defects, acute febrile illness, and severe multiple trauma, may also require attention, but prolonged hypoxemia poses the highest risk for cardiac arrest and demands specialized expertise in managing pediatric patients with this condition.

Correct Answer: A

Rationale: The correct answer is A: 'Has increased airway obstruction.' High-pitched wheezes extending throughout exhalation indicate a worsening airway obstruction, leading to increased resistance in the airways. Low-pitched wheezes present on the final half of exhalation may suggest some level of obstruction, but the change to high-pitched wheezes throughout exhalation indicates a progression in the obstruction. Choice B is incorrect as the change in wheeze characteristics signifies deterioration rather than improvement. Choice C is incorrect as suctioning is not indicated based on the wheeze assessment findings. Choice D is incorrect as hyperventilation does not typically present with wheezes and is not supported by the information provided.
