The nurse notes that a client's cardiac monitor shows that every other beat is earlier than expected, has no visible P wave, and has a QRS complex that is wide and bizarre in shape. How will the nurse document the rhythm?
Ventricular tachycardia
Multifocal premature ventricular contractions
Ventricular couplets
Ventricular bigeminy
The Correct Answer is D
A. Ventricular tachycardia is a run of three or more consecutive ventricular beats at a rapid rate, not every other beat.
B. Multifocal premature ventricular contractions (PVCs) arise from different ventricular foci and have different shapes, but this scenario describes uniform shape and consistent pattern.
C. Ventricular couplets are two consecutive PVCs, not a pattern where every other beat is abnormal.
D. Ventricular bigeminy is the correct term for a rhythm in which every other beat is a premature ventricular contraction (PVC). These PVCs typically have no visible P wave and a wide, bizarre QRS complex, matching the description given.

C. Radiation exposure – While it may affect cardiac tissue, it is not considered a risk factor for infective endocarditis.
D. Cardiac catheterization – While it is an invasive procedure, it is not a major or common risk factor for infective endocarditis compared to prosthetic valves or structural heart defects.
Correct Answer is D
Explanation
A. Taking a diuretic before sleep can lead to nocturia (frequent urination at night), disrupting sleep. Also, fluid intake may need to be restricted, not encouraged.
B. Clients with heart failure are usually advised to limit sodium to 2 grams or less per day, not 4 grams, to help reduce fluid retention.
C. Naproxen (a NSAID) is not recommended for clients with heart failure as it can cause fluid retention and worsen the condition.
D. Slowing down when tired after exercise shows an understanding of energy conservation and pacing—appropriate for managing heart failure symptoms. This indicates that teaching was effective.
