Final answer:
A nurse should closely monitor a patient throwing PVC's for symptoms such as cherry-red skin, cyanosis, confusion, nausea, gasping for air, seizures, and metabolic acidosis. Vital signs, oxygen saturation levels, and ECG readings can aid in assessing PVC severity and frequency.
Step-by-step explanation:
A nurse should monitor a patient who is throwing PVC's (premature ventricular contractions) very closely for possible symptoms such as cherry-red skin, cyanosis, confusion, nausea, gasping for air, seizures, and metabolic acidosis. PVC's are abnormal heartbeats that occur earlier than expected, causing the heart's ventricles to contract too soon. Monitoring the patient's vital signs, oxygen saturation levels, and electrocardiogram (ECG or EKG) readings can help the nurse assess the severity and frequency of PVC's and take appropriate actions.
