A. Look for P waves on the strip
Looking for P waves is important for assessing atrial activity, but it does not directly calculate heart rate.
B. Count how many QRS occur in a 6 second strip
Counting how many QRS complexes occur in a 6-second strip and multiplying by 10 is a quick and accurate way to calculate heart rate.
C. Read the monitor or electrocardiogram interpretation.
Reading the monitor or ECG interpretation provides information about the rhythm and morphology of the heart, but it does not directly calculate heart rate.
D. Measure the T waves
Measuring T waves is important for assessing cardiac repolarization, but it does not directly calculate heart rate.

A nurse is caring for a client diagnosed with heart failure (HF) and atrial fibrillation. The client reports feeling of palpitations and shortness of breath. The nurse is aware that clients Atrial Fibrillation (AF) are at risk for which complication?
A. Hypertensive crisis
Hypertensive crisis is not a common complication of atrial fibrillation.
B. Cardiogenic shock
Cardiogenic shock is not a common complication of atrial fibrillation.
C. Flash pulmonary edema
Flash pulmonary edema is not a common complication of atrial fibrillation.
D. Embolic cerebral vascular accident
Atrial fibrillation can lead to the formation of blood clots in the atria, which can then travel to the brain and cause a stroke or embolic cerebral vascular accident.

A nurse is giving a presentation about preventing deep-vein thrombosis (DVT). Which of the following should the nurse include as a risk factor for this disorder? (Select all that apply.)
A. BMI of 20
A BMI of 20 is not typically considered a risk factor for deep vein thrombosis.
B. High calcium intake
High calcium intake is not typically considered a risk factor for deep vein thrombosis.
C. Oral contraceptive use
Oral contraceptive use is a risk factor for deep vein thrombosis due to the estrogen content.
D. Immobility
Immobility is a risk factor for deep vein thrombosis due to decreased venous return.
E. Hypertension
Hypertension is not typically considered a risk factor for deep vein thrombosis.

A nurse is assessing a patient with known mitral valve regurgitation. The nurse should expect to hear which of the following heart sounds?
A. Murmur
Mitral valve regurgitation typically presents with a murmur, which is a characteristic sound associated with the backflow of blood into the left atrium during systole.
B. S3 and S4
S3 and S4 are not typical heart sounds and do not relate to mitral valve regurgitation.
C. Click
A click is typically associated with mitral valve prolapse, not mitral valve regurgitation.
D. Friction rub
A friction rub is typically associated with pericarditis, not mitral valve regurgitation.
