Multiple Choice

Which method should a nurse use to assess a client for a pulse rate deficit?

Assess the carotid pulse while the client is lying down.

Measure the radial pulse rate and multiply by two.

Count the apical pulse for 15 seconds and multiply by four.

Simultaneously measure the apical and radial pulse rates and compare them.

Verified step by step guidance

Understand the concept of pulse rate deficit: It is the difference between the apical pulse rate and the radial pulse rate. This can indicate a discrepancy in heartbeats reaching the periphery.

Identify the apical pulse: The apical pulse is measured at the apex of the heart, typically found at the fifth intercostal space at the midclavicular line on the left side of the chest.

Identify the radial pulse: The radial pulse is measured at the wrist, where the radial artery is located, on the thumb side of the forearm.

Simultaneously measure both pulses: Use a stethoscope to listen to the apical pulse while palpating the radial pulse with your fingers. This allows for an accurate comparison of the two rates.

Compare the two pulse rates: Count the number of beats for each pulse over the same time period, typically one minute, and calculate the difference to determine if there is a pulse rate deficit.
