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?

A.

S3 heart sounds

B.

Increase in point of maximum impulse (PMI)

C.

Irregular pulsations

D.

Bradycardia

Answer and Explanation

The Correct Answer is C

A. S3 heart sounds. An S3 sound is more indicative of heart failure rather than PVCs specifically.

 

B. Increase in point of maximum impulse (PMI). PMI is typically displaced in conditions like ventricular hypertrophy or heart failure, not PVCs.

 

C. Irregular pulsations. PVCs are extra beats that interrupt the heart’s normal rhythm, leading to irregular pulsations on palpation.

 

D. Bradycardia. PVCs usually occur in the context of normal or elevated heart rates rather than bradycardia.

Correct Answer is B

Explanation

A. Bounding peripheral pulses: Hypokalemia typically causes weak, thready pulses rather than bounding ones.

B. Decreased deep-tendon reflexes: Hypokalemia can cause muscle weakness and decreased deep-tendon reflexes due to impaired neuromuscular function.

C. Hyperactive bowel sounds: Hypokalemia generally causes decreased or hypoactive bowel sounds due to slowed smooth muscle contraction.

D. Restlessness: Restlessness is not a typical sign of hypokalemia; hypokalemia more commonly causes weakness, lethargy, or fatigue.

Correct Answer is D

Explanation

A. Partial thromboplastin time (PTT) 55 seconds: This PTT value is within the therapeutic range for a client on heparin therapy.

B. Hematocrit 45%: This hematocrit value is within normal limits and is not concerning.

C. White blood cell count 8,000/mm³: A WBC count of 8,000/mm³ is within the normal range and does not require reporting.

D. Platelets 74,000/mm³: A low platelet count (thrombocytopenia) can indicate heparin-induced thrombocytopenia (HIT), a potentially serious complication of heparin therapy.
