The patient is admitted with a suspected acute myocardial infarction (AMI). In assessing the 12-lead electrocardiogram (ECG) changes, which findings would indicate to the nurse that the patient is in the process of a myocardial infarction (MI)?

Depressed ST-segment on ECG and elevated total CPK

Depressed ST-segment on ECG and normal cardiac enzymes

ST-segment elevation on ECG and elevated CK-MB or troponin levels

Q wave on ECG with normal enzymes and troponin levels

Answer and Explanation

The Correct Answer is C

A. A depressed ST-segment is often associated with ischemia or non-ST elevation myocardial infarction (NSTEMI), not an ongoing MI.

B. A depressed ST-segment with normal cardiac enzymes suggests ischemia rather than an active MI.

C. ST-segment elevation on ECG combined with elevated cardiac biomarkers such as CK-MB or troponin levels is a hallmark of an acute ST-segment elevation myocardial infarction (STEMI), indicating an ongoing MI.

D. A Q wave on ECG indicates an old infarction and is not associated with an acute MI if enzymes and troponin levels are normal.

Correct Answer is D

Explanation

A. A coronary artery bypass graft is used to treat coronary artery disease but is not typically indicated for end-stage heart failure.
B. Percutaneous coronary intervention is also used for coronary artery disease, not for improving quality of life in terminal heart failure.
C. This option dismisses potential interventions that could improve quality of life, such as an LVAD.
D. An LVAD is a mechanical pump that assists the left ventricle in pumping blood, often used as a bridge to heart transplant or as a long-term solution to improve quality of life in patients with terminal heart failure.

A. Deaths from patients with communicable diseases do not need to be reported to organ procurement agencies. B. Tissue donation is involuntary. C. Organ donation can be authorized by a client's surrogate. D. Each organ donation request should be reported to a facility's committee.

Correct Answer is C

Explanation

A. Deaths of patients with communicable diseases still need to be reported because tissue and organ viability must be assessed on a case-by-case basis.

B. Tissue donation is voluntary and requires consent from the patient or their legal representative.

C. Organ donation can be authorized by a client's surrogate if the client has not previously given or refused consent. This allows for the surrogate to make decisions in line with the client’s wishes or best interests.

D. While facilities may have committees involved in the process, reporting is to organ procurement organizations, not solely to a facility's committee.
