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. Documentation of waveform values is important but does not directly enhance patient safety during monitoring.

B. Limiting the pressure tubing length can help maintain accuracy, but it is not the primary safety measure.

C. Zero referencing is crucial for accurate readings, but it must be done in conjunction with ensuring alarms are active.

D. Ensuring that alarm limits are turned on and appropriately set is the best safety measure to immediately alert the nurse to any critical changes in the patient's status.

A. Obtain a stat chest x-ray to verify proper catheter placement. B. Zero reference and level the catheter at the phlebostatic-axis. C. Increase supplemental oxygen and notify respiratory therapy. D. Notify the provider immediately of the assessment findings.

Correct Answer is B

Explanation

A. Obtaining a stat chest x-ray is important if catheter misplacement is suspected, but in this situation, ensuring the accuracy of the pressure reading through proper leveling and zeroing is the priority.
B. Zero referencing and leveling the catheter at the phlebostatic axis is essential to ensure accurate readings of the pulmonary artery pressure, which is critical for patient assessment and management.
C. Increasing supplemental oxygen is unnecessary given the patient’s stable oxygen saturation and normal respiratory status.
D. While notifying the provider is important, ensuring the accuracy of the pressure reading by leveling and zeroing the catheter should be done first.
