A client is admitted to the emergency room with chest pain and a suspected diagnosis of acute myocardial infarction (MI). Which test would the nurse expect the physician to order to make a definitive diagnosis of MI?

Choice A rationale

A decreased white blood cell count indicates the body's response to infection is improving, showing the effectiveness of the antibiotics.

Choice B rationale

Increased chest pain and shortness of breath would suggest worsening of the condition, not improvement.

Choice C rationale

Adventitious breath sounds and increased cough are signs that pneumonia may be persisting or worsening.

Choice D rationale

Improved appetite and weight gain are positive signs but are not direct indicators of the effectiveness of antibiotic treatment.

Choice A rationale

Administering insulin when the breakfast tray arrives may not provide sufficient time for the insulin to take effect before the client begins eating, potentially leading to hyperglycemia.

Choice B rationale

Administering insulin at 07: is too early and may result in hypoglycemia before the client eats breakfast.

Choice C rationale

Administering insulin at 07: allows sufficient time for the insulin to take effect before the client eats breakfast, helping to maintain appropriate blood glucose levels.

Choice D rationale

Administering insulin 30 minutes after breakfast is too late and could result in hyperglycemia since the client would have already consumed carbohydrates.
