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.

(B) American Association of Critical Care Nurses (AACN) website: The AACN is a credible source of information for nurses working in critical care. It provides resources, education, and advocacy to ensure optimal care for critically ill patients.

(C) Association of Women’s Health, Obstetric, and Neonatal Nurses (AWHONN) website: AWHONN is a reputable organization that promotes the health of women and newborns. Its website provides evidence-based clinical practice guidelines and other resources for nurses.

(D) A pamphlet about hypoglycemia from the American Diabetes Association: The American Diabetes Association is a reputable source of information on diabetes. A pamphlet from this organization about hypoglycemia would be based on the latest research and would be a credible source of information.

(E) Cumulative Index of Nursing and Allied Health Literature (CINAHL) website: CINAHL is a comprehensive source of full-text for nursing & allied health journals, providing full text for more than 610 journals indexed in CINAHL. This is a highly respected research tool for nurses and allied health professionals.

A. Metabolic alkalosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic acidosis

Correct Answer is D

Explanation

(A) Metabolic alkalosis: This condition is characterized by a high blood pH (>7.45) and a high bicarbonate level (>26 mEq/L). The client’s pH and bicarbonate levels are both lower than normal, which rules out metabolic alkalosis.

(B) Respiratory acidosis: This condition is characterized by a low blood pH (<7.35) and a high PaCO2 level (>45 mm Hg). Although the client’s pH is low, the PaCO2 level is also low, which rules out respiratory acidosis.

(c) Respiratory alkalosis: This condition is characterized by a high blood pH (>7.45) and a low PaCO2 level (<35 mm Hg). The client’s pH is low, which rules out respiratory alkalosis.

(D) Metabolic acidosis: This condition is characterized by a low blood pH (<7.35) and a low bicarbonate level (<22 mEq/L). The client’s pH is 7.26 and bicarbonate level is 14 mEq/L, both of which are lower than normal. This indicates metabolic acidosis, which is common in clients with acute kidney injury as the kidneys are unable to excrete hydrogen ions and reabsorb bicarbonate. Therefore, the nurse should identify that the client is experiencing metabolic acidosis.
