ATI Fundamentals Exam Special Unit ADN | Nurselytic

Correct Answer: C

Rationale: The correct answer is C: Assess the apical pulse for a full minute. The nurse should assess the apical pulse when a radial pulse is irregular because the apical pulse is more accurate in detecting irregularities. By counting the apical pulse for a full minute, the nurse can accurately determine the rate, rhythm, and regularity of the heartbeat. This action allows for a more comprehensive assessment of the client's cardiovascular status.


Choice A is incorrect because assessing the pedal pulses does not provide an accurate assessment of the client's heart rhythm.
Choice B is incorrect because using a Doppler device on the apical pulse is unnecessary and may not provide a more accurate assessment than manually counting the pulse.
Choice D is incorrect because assessing the pedal pulses with a Doppler device is not relevant to determining the irregularity of the radial pulse.
