A nurse is collecting data from a client who is receiving continuous cardiac monitoring that is indicating premature ventricular contractions (PVCs). Which of the following findings should the nurse expect when assessing the client?

S3 heart sounds

Irregular pulsations

Bradycardia

Increase in point of maximum impulse (PMI)

Answer and Explanation

The Correct Answer is B

A) S3 heart sounds:
S3 heart sounds are typically associated with heart failure and are not directly related to premature ventricular contractions (PVCs). S3 heart sounds occur during the early diastolic phase and are heard immediately after S2.

B) Irregular pulsations:
This is the correct choice. Premature ventricular contractions (PVCs) can cause irregular pulsations in the pulse. PVCs are premature contractions originating from the ventricles, which can interrupt the normal rhythm of the heart and lead to irregularities in the pulse.

C) Bradycardia:
Premature ventricular contractions (PVCs) can lead to various rhythm disturbances, but bradycardia (slow heart rate) is not typically associated with PVCs. In fact, PVCs often occur in the context of tachycardia (rapid heart rate).

D) Increase in point of maximum impulse (PMI):
An increase in the point of maximum impulse (PMI) is not typically associated with premature ventricular contractions (PVCs). The PMI refers to the location where the apex of the heart is palpated during systole and is not directly affected by PVCs.

Correct Answer is A

Explanation

A) Tingling of the lips:
This is the correct choice. Hypocalcemia, which is low calcium levels in the blood, can lead to neurological symptoms such as tingling sensations around the lips and in the extremities. This occurs due to the effect of low calcium levels on the nervous system.

B) Hypoactive bowel sounds:
Hypocalcemia primarily affects neuromuscular function rather than gastrointestinal function. While calcium imbalances can impact gastrointestinal motility, hypoactive bowel sounds are not typically associated with hypocalcemia.

C) Skeletal muscle weakness:
Skeletal muscle weakness is a common symptom of hypocalcemia. Low calcium levels affect the ability of muscles to contract effectively, leading to weakness and fatigue.

D) Decreased deep-tendon reflexes:
Hypocalcemia can actually lead to increased deep-tendon reflexes rather than decreased reflexes. Calcium plays a role in neuromuscular transmission, and low levels can result in hyperexcitability of nerves, leading to increased reflexes rather than decreased reflexes.

A. Atropine B. Verapamil C. Digoxin D. Carvedilol

Correct Answer is A

Explanation

A) Atropine:
Atropine is a medication used to increase heart rate. It acts by blocking the parasympathetic nervous system, leading to increased heart rate. It is commonly used to treat bradycardia, which is characterized by a heart rate less than 60 beats per minute. In this scenario, with the client's apical heart rate at 49/min, indicating bradycardia, the nurse should prepare to administer atropine to increase the heart rate.

B) Verapamil:
Verapamil is a calcium channel blocker that can decrease heart rate. It is used to treat various cardiac conditions, but it is not appropriate for a client with bradycardia, as it would further lower the heart rate.

C) Digoxin:
Digoxin is a medication used to treat heart failure and certain arrhythmias, but it does not directly increase heart rate. In fact, it can exacerbate bradycardia in some cases.

D) Carvedilol:
Carvedilol is a beta-blocker that can decrease heart rate. It is used to treat hypertension, heart failure, and other cardiovascular conditions, but it is not appropriate for a client with bradycardia, as it would further lower the heart rate.
