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 A

Explanation

A. Continuous IV infusion is the most appropriate route for treating hypertensive emergencies because it allows for rapid and controlled reduction of blood pressure, which is crucial in preventing target organ damage.
B. Sublingual administration is not recommended in hypertensive emergencies because it does not allow for the precise control needed in these situations.
C. Intramuscular administration is generally not used for antihypertensive agents in emergencies because it does not provide the rapid and adjustable response that IV infusion does.
D. Oral administration is too slow in onset for hypertensive emergencies and is not appropriate when immediate blood pressure control is necessary.

A. Cluster nursing activities so that the patient has uninterrupted rest periods. B. Silence the alarms on the cardiac monitors to allow 30- to 40-minute naps. C. Administer sedatives or opioids at bedtime to promote sleep. D. Eliminate assessments between 2200 and 0600 to allow uninterrupted sleep

Correct Answer is A

Explanation

A. Clustering nursing activities helps to minimize interruptions, allowing the patient to have longer periods of uninterrupted rest, which is essential for recovery and reducing sensory disturbances from sleep deprivation.

B. Silencing alarms could compromise patient safety and is not recommended.

C. Administering sedatives or opioids should be done cautiously and is not a first-line approach for promoting sleep, especially if non-pharmacological methods can be effective.

D. While reducing nighttime assessments may help with sleep, it is not always feasible and should be balanced with the need for monitoring the patient’s condition.
