The nurse is assessing the client with a recent pacemaker placement. The client's monitor is displaying what type of rhythm?

The pacemaker is pacing abnormally

Biventricular, pacing in both ventricles

Atrial paced rhythm

Atrial and ventricular pacing

Answer and Explanation

The Correct Answer is D

A.   This would be concerning, but it is not the correct choice. If a pacemaker is functioning abnormally, it would require an assessment and troubleshooting, not simply a routine rhythm.
B.   This is typical for biventricular pacemakers used in heart failure patients, but it would not apply to a patient with a standard pacemaker unless specified. A recent pacemaker placement does not necessarily indicate biventricular pacing.
C.   This is correct if only the atrium is paced; however, in the case of a typical pacemaker like DDD (dual- chamber pacemaker), both the atrium and ventricle are paced.
D.   This is correct for dual-chamber pacemakers (like DDD), which pace both the atrium and the ventricle to coordinate the heart's rhythm.

Correct Answer is C

Explanation

A. Hypermagnesemia can cause bradycardia and hypotension, but it is less commonly associated with PVCs. This does not align with the lab results provided.
B. Hypocalcemia can cause arrhythmias, but it is not the most likely cause of PVCs in this case, considering other findings.
C. Hypokalemia (low potassium) is a known cause of PVCs. The patient's potassium level is 2.8 mEq/L, which is significantly low and most likely contributing to the PVCs.
D. Although hyperglycemia can affect cardiac function, it is less commonly linked to PVCs compared to electrolyte imbalances, such as hypokalemia.

A. weigh the client to obtain a baseline for comparison B. Insert an indwelling catheter C. Draw blood for chemistry studies and a CBC D. Administer furosemide 40mg PO

Correct Answer is A

Explanation

A. Weighing the client provides an important baseline for monitoring fluid retention and determining the effectiveness of treatments such as diuretics. Rapid changes in weight can indicate worsening heart failure and fluid accumulation.
B. Inserting an indwelling catheter is not indicated unless there are concerns about urinary retention or output, which are not the priority here.
C. Drawing blood for chemistry studies and a CBC is important but it does not directly address the immediate concern of fluid retention and worsening heart failure.
D. Administering furosemide may be necessary depending on the client's condition, but first establishing a baseline weight is important before making further treatment decisions.
