20 Questions
Why should rectal temperature measurements be used with caution in certain clients?
To avoid stimulating the vagus nerve
What is the normal range for rectal temperature?
36.3 – 38.1 °C
How does the parasympathetic nervous system affect heart rate?
It decreases heart rate
What is the normal pulse rate range for adults?
60 – 100 bpm
Why should rectal temperature measurements not be used in newborns or children with diarrhea?
Due to potential vagus nerve stimulation
What is the definition of tachycardia?
A heart rate (HR) of 100 - 180 bpm
What is bradycardia and what are some common causes?
A heart rate (HR) of less than 60 bpm, caused by vagal stimulation and severe pain
How is pulse amplitude graded?
0 = Weak, 1+ = Diminished, 2+ = Normal, 3+ = Bounding
What term is used to describe an irregular pulse rhythm?
Dysrhythmia
When should the apical pulse be assessed?
When giving medications that can alter heart rate and rhythm
What is a potential source of error in blood pressure assessment that can lead to falsely low assessments?
Using a cuff that is too small or too narrow
Which technique is used to measure arterial oxyhemoglobin saturation noninvasively?
Pulse oximetry
What is the usual range for oxygen saturation in percentage?
95% - 100%
How does the conical shape of an obese arm affect blood pressure assessment?
It makes it difficult to fit the blood pressure cuff properly
Which factor does NOT affect oxygen saturation levels?
Temperature
What is the term used to describe the difference between apical pulse rate and radial pulse rate?
Pulse deficit
Where should a nurse listen with a stethoscope to assess the apical pulse?
Over the apex of the heart
What does the term 'diffusion' refer to in the context of respiration?
Exchange of O2 and CO2 between alveoli and circulating blood
Which receptors are responsible for detecting an increase in CO2, triggering a powerful respiratory response?
Chemo receptors located in the aortic arch
What does the term 'perfusion' involve in the context of respiration?
Exchange of O2 and CO2 between circulating blood and tissue cells
Learn how to assess the apical-radial pulse in a clinical setting by using a stethoscope to listen for one minute over the apex of the heart. Understand the difference between the apical pulse rate and radial pulse rate, known as pulse deficit.
