A nurse is caring for a client who reports chest pain. Which of the following laboratory findings indicates myocardial damage?

Troponin 11.8 ng/mL

Erythrocyte sedimentation rate (ESR) 17 mm/hr

Human B-type natriuretic peptide 88 pg/ml.

aPTT 80 seconds

Answer and Explanation

The Correct Answer is A

A. Troponin is a protein released into the bloodstream when there is damage to the heart muscle (myocardium), such as during a heart attack. Elevated troponin levels indicate myocardial injury or damage, making this the correct choice for indicating myocardial damage.

B. Erythrocyte sedimentation rate (ESR) measures the rate at which red blood cells settle in a tube of blood. It is a non-specific marker of inflammation and is not specific to myocardial damage.

C. Human B-type natriuretic peptide (BNP) is released by the heart in response to increased pressure and volume. Elevated levels are indicative of heart failure, not necessarily myocardial damage.

D. Activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot. It is used to monitor the effectiveness of anticoagulant therapy and is not specific to myocardial

damage.

Correct Answer is D

Explanation

A. Taking pancrelipase on an empty stomach may not provide optimal effectiveness as there would be no food in the stomach to mix with the enzymes for proper digestion.

B. Taking pancrelipase 1 hour before meals may not be as effective as taking it with meals because the enzymes need to be present when food enters the stomach for digestion.

C. Taking pancrelipase 1 hour after meals may not be as effective as taking it with meals because the enzymes need to be present when food enters the stomach for digestion.

D. Taking pancrelipase with meals is the correct instruction. Pancrelipase supplements the digestive enzymes that are deficient in individuals with cystic fibrosis, helping them digest food properly. Taking it with meals ensures that the enzymes are present when food enters the stomach, optimizing digestion and nutrient absorption.

A. A client who is at 38 weeks of gestation and reports irregular uterine contractions B. A client who is at 39 weeks of gestation and is scheduled for a weekly nonstress test (NST) C. A client who is at 40 weeks of gestation and is scheduled for an induction of labor D. A client who is at 36 weeks of gestation and reports decreased fetal movement for 2 days

Correct Answer is D

Explanation

A. Irregular uterine contractions at 38 weeks of gestation may not be a concern unless they become regular and more intense.

B. A client scheduled for a nonstress test (NST) at 39 weeks of gestation can typically wait until after attending to more urgent matters.

C. A client scheduled for an induction of labor at 40 weeks of gestation is not necessarily a priority unless there are urgent concerns.

D. Decreased fetal movement, especially for 2 days at 36 weeks of gestation, requires immediate assessment to ensure fetal well-being.
