Final answer:
The nurse may observe hypotension as a sign in a client with premature ventricular contractions, as PVCs can disrupt regular heart rhythm, leading to lowered blood pressure.
Step-by-step explanation:
The nurse is caring for a client who has premature ventricular contractions.
A symptom that is observed in this client could be hypotension. Premature ventricular contractions (PVCs) are extra heartbeats that disrupt the regular heart rhythm and can lead to insufficient blood pressure. While other symptoms such as fluttering in the chest or nausea can also be associated with PVCs, hypotension stands out as a clinical sign that can be observed and measured. Fever is not typically related to PVCs, and while nausea can occur, it is not as specifically linked to the effect of PVCs on circulation as hypotension is.
