Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.
The Correct Answer is []
- Myocardial infarction (MI) is suggested by chest pain radiating to the left arm, diaphoresis, shortness of breath, and epigastric discomfort. The pain described as "sharp, tight, and like indigestion" aligns with cardiac ischemia.
- Administering oxygen helps improve myocardial oxygenation, reducing ischemia.
- Aspirin 325 mg is a standard intervention in suspected MI to prevent further platelet aggregation and reduce the risk of worsening thrombosis in the coronary arteries.
- Monitoring vital signs is critical to assess for hemodynamic stability and signs of worsening cardiac function (e.g., hypotension, tachycardia).
- Monitoring ECG rhythm helps detect ST-elevation or other ischemic changes and assess for life-threatening arrhythmias.
- Morphine may be used for chest pain, but it is now considered secondary to nitroglycerin and beta-blockers.
- Verapamil is a calcium channel blocker used for rate control in arrhythmias but is not first-line for acute MI.
- Platelet count and WBC count are not immediately relevant to MI management.
- Serum glucose levels may be affected by stress but are not a primary concern in acute MI management.

Correct Answer is A
Explanation
A. Digoxin is a positive inotropic agent, meaning it increases the force of cardiac contractions. This helps improve cardiac output in patients with heart failure.
B. Digoxin does not decrease the force of contractions; instead, it strengthens them, making it beneficial for heart failure treatment.
C. Digoxin is commonly used in heart failure management, particularly in cases of systolic dysfunction or atrial fibrillation.
D. Digoxin decreases heart rate by slowing conduction through the atrioventricular (AV) node, making it useful in atrial fibrillation, but its primary benefit in heart failure is increasing contractility.
Correct Answer is A
Explanation
A. Counting the number of QRS complexes in a 6-second strip and multiplying by 10 provides an estimate of the heart rate per minute.
B. Measuring T waves is used to assess repolarization abnormalities, not to determine heart rate.
C. While the monitor provides a heart rate reading, manual calculation is essential for verifying accuracy.
D. P waves indicate atrial activity but are not used to calculate the overall heart rate.
