Myoglobin

BNP

CK-MB isoenzymes

Answer and Explanation

The Correct Answer is A

A.   These are the most specific and sensitive markers for diagnosing a heart attack. They are released into the bloodstream when heart muscle is damaged.
B.   Myoglobin is an early marker of heart muscle damage, but it is less specific than troponin and can be elevated in other conditions.
C.   B-type natriuretic peptide is a hormone primarily used to diagnose heart failure, not acute myocardial infarction (heart attack).
D.   Creatine kinase-MB is an older marker for heart damage, but it is less specific than troponin and takes longer to rise in the blood.

Correct Answer is C

Explanation

A. The patient should be the only one to control the PCA pump. This is to prevent overmedication and to ensure the patient is in control of their pain management.
B. While it's important to use the PCA responsibly, the device is designed to prevent overdose. It has built-in safeguards to limit the amount of medication delivered.
C. This statement indicates that the patient understands the importance of communicating with the nurse about pain management. If the PCA is not effectively controlling pain, the nurse needs to be notified to adjust the medication or explore other options.
D. The PCA is designed to be used proactively to manage pain, not reactively when pain is severe. Waiting until pain is unbearable can make it more difficult to control.

A. A low Hgb A1C means that the patient is hypoglycemic, and should drink grape juice B. A Hgb A1C value of greater than 6.5 indicates the patient is likely Diabetic C.
