Which of the following terms is used when an adult has a pulse rate of 110 to 140 beats per minute?
Dysrhythmia
Tachycardia
Bradycardia
Pyrexia
The Correct Answer is B
A. Dysrhythmia. Dysrhythmia refers to an irregular heart rhythm, not necessarily a fast heart rate. Tachycardia can be regular or irregular.
B. Tachycardia. Tachycardia is defined as a heart rate above 100 beats per minute in adults. A pulse rate of 110 to 140 bpm falls within this range.
C. Bradycardia. Bradycardia refers to a slow heart rate (below 60 bpm), which is the opposite of tachycardia.
D. Pyrexia. Pyrexia refers to fever (elevated body temperature), not an increased heart rate.

Correct Answer is A
Explanation
A. Carotid. The carotid arteries supply blood to the brain, and compressing both simultaneously can reduce cerebral blood flow, potentially causing dizziness, syncope, or loss of consciousness. Therefore, carotid pulses should be assessed one at a time.
B. Radial. The radial pulse can be safely assessed bilaterally at the same time since it does not affect central circulation or brain perfusion.
C. Brachial. The brachial pulse can also be assessed bilaterally without risk, as it does not impact blood flow to critical organs like the brain.
D. Femoral. The femoral pulse can be checked simultaneously on both sides to assess circulation and perfusion, especially in cases of suspected arterial insufficiency.
Correct Answer is D
Explanation
A. Positional BP readings. While orthostatic blood pressure readings can assess for postural hypotension, there is no indication in the current vitals that the client is experiencing symptoms such as dizziness or syncope.
B. Carotid pulse and temperature. The client’s temperature is already documented as normal, and the carotid pulse is not needed when an irregular radial pulse has been noted. The apical pulse is the preferred method to assess for irregularities.
C. Full respiratory system assessment. The respiratory rate is within the normal range, with regular rhythm and normal depth, so a full respiratory assessment is not the immediate priority.
D. Apical pulse for one minute. An irregular radial pulse suggests the possibility of an arrhythmia. The apical pulse provides a more accurate assessment of heart rhythm and rate, ensuring a complete evaluation of the irregularity.
