A nurse is preparing to administer blood to a client. Which of the following actions should the nurse take to identify the client? (Select All that Apply.)

A. "Cardiac enzymes assist in diagnosing the presence of pulmonary congestion.": Cardiac enzymes are not used to diagnose pulmonary congestion. They are specific markers used to assess damage to the heart muscle, particularly after a myocardial infarction (MI).

B. "These tests help determine the degree of damage to the heart tissues.": This statement is correct. Cardiac enzyme studies, such as troponin levels, CK-MB (creatine kinase-MB), and LDH (lactate dehydrogenase), are used to evaluate the extent of myocardial damage during and after an MI. Elevated levels of these enzymes indicate myocardial injury.

C. "These tests will enable the provider to determine the heart structure.": While cardiac imaging studies like echocardiograms or angiograms are used to assess heart structure, cardiac enzymes are primarily used to evaluate myocardial damage and not heart structure.

D. "Cardiac enzymes will identify the location of the MI.": Cardiac enzymes can indicate the presence of an MI and the extent of myocardial damage, but they do not specifically identify the location of the MI within the heart. Additional diagnostic tests, such as electrocardiograms (ECGs) and imaging studies, are often used to determine the location of the MI.

A. "If I take my blood pressure and it is normal, I don't have to take my blood pressure pills": This statement reflects a misunderstanding of hypertension management. Blood pressure medications are typically prescribed to help control blood pressure over the long term, regardless of individual blood pressure readings. Stopping medication without consulting a healthcare provider can be dangerous and is not recommended.

B. "When getting up from bed, I will sit for a short period before standing up": This statement demonstrates an understanding of orthostatic hypotension prevention, which is important for clients with hypertension and can be a side effect of certain medications.

C. "I will consult a dietician to help get my weight under control": This statement indicates the client's awareness of the importance of weight management in hypertension control and is a positive step toward healthy lifestyle changes.

D. "I think I'm going to sign up for a yoga class twice a week to help reduce my stress": This statement shows the client's proactive approach to stress reduction, which is beneficial for hypertension management as stress can contribute to elevated blood pressure.
