A charge nurse is providing teaching to a newly licensed nurse on how to clean surfaces contaminated with blood. Which of the following agents should the nurse include in theteaching?

A. Weight loss while using a diaphragm is not typically an urgent concern and may be related to dieting; the client should be advised to follow up with her primary care provider for further

evaluation.

B. Cramping and bleeding are common side effects following an IUD insertion and typically do not require immediate attention unless severe or accompanied by other concerning symptoms;

the client should be advised to monitor her symptoms and follow up if they worsen.

C. Breakthrough bleeding is a common side effect of starting oral contraceptives and may resolve on its own after a few cycles; the client should be advised to continue taking her pills as prescribed and to follow up if the bleeding persists or worsens.

D. Shoulder pain following a laparoscopic procedure may indicate a potential complication such as referred pain from gas used during the procedure or more serious issues such as internal bleeding or organ injury; the client should be instructed to come to the clinic for further

evaluation and management.

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.
