What describes the strength of left ventricular contraction and is graded on a scale from 0 to +3?
Pulse amplitude
Which method is preferred for assessing pulses in infants and children under 2 years?
Assessing apical pulse
What does an irregular pulse pattern with beats and pauses occurring at unequal intervals indicate?
Dysrhythmia
When is a Doppler ultrasound used for pulse assessment?
When peripheral pulses are difficult to palpate or auscultate
Where should you use a stethoscope to listen for 1 minute to assess the apical pulse?
Between the 5th and 6th rib in the midclavicular line
What does a difference between the apical pulse rate and radial pulse rate indicate?
Pulse deficit due to weak heart thrust or peripheral disease
What is the primary function of diffusion in the respiratory system?
Exchange of O2 and CO2 between alveoli and circulating blood
What controls respiration and serves as a vital sign for ventilation?
Activation of respiratory centers in the brain and chemoreceptors
What is the purpose of measuring respirations?
To establish a baseline of respiratory function
What is the main advantage of using the popliteal artery for blood pressure assessment?
It is less affected by the conical shape of an obese arm
Which factor does not affect oxygen saturation?
Respiration
What is the purpose of pulse oximetry?
To monitor arterial oxyhemoglobin saturation
What can cause falsely high assessments of blood pressure?
Using a cuff that is too small or too narrow
Why is the systolic blood pressure usually 10-40 mmHg higher when assessed using the popliteal artery?
The popliteal artery is closer to the heart than the brachial artery
What is the normal range of rectal temperature?
36.3 - 38.1 °C
How does insertion of a rectal thermometer affect the heart rate?
It stimulates the vagus nerve and causes a decrease in heart rate
Which system decreases the heart rate via the vagus nerve?
Parasympathetic Nervous System
What is the normal pulse rate range for adults?
60 - 100 bpm
What happens to the pulse rate across the lifespan?
It gradually diminishes across the lifespan
What is the normal oral temperature range?
35.9 - 37.5 °C
Why should a nurse wait 15-30 minutes before taking an oral temperature if the client has been consuming hot or cold foods or liquids, or smoking?
To prevent inaccurate temperature readings
In what scenario should an oral temperature not be taken?
If the patient has a broken jaw that is wired closed
What is the average duration for taking an oral temperature?
1 minute
Which site is often used to estimate core body temperature?
Tympanic membrane
What is the preferred method to measure blood pressure in adults?
Auscultation
Which of the following indicates positive results for orthostatic hypotension?
SBP decrease of more than 20mmHg
Which equipment is preferred for measuring blood pressure in adults?
Sphygmomanometer
What is the recommended site for accurate assessment of blood pressure in clients?
Upper arm
What do automated blood pressure monitors determine by analyzing?
Blood flow sounds
What is the primary source of heat produced in the body?
Hormones such as epinephrine and norepinephrine
Where is body temperature regulation primarily controlled?
Hypothalamus
Which part of the body has a higher temperature than surface temperature?
Intracranial area
What does the release of thyroid hormone contribute to in terms of body temperature regulation?
Heat production
Which factor reduces the surface area of skin available for heat loss?
Piloerection (goose bumps)
Which method provides the core body temperature measurement?
Rectal measurement
Which location has a lower temperature compared to core body temperature?
Axillary (armpit)
What defines the term 'pulse' in relation to cardiovascular assessment?
(Heart rate) Beat or thrust felt with each contraction of the heart
Which factor affects blood pressure regulation by increasing or decreasing heat loss?
(Body temperature) Difference between heat produced by the body and heat lost to the environment
This quiz covers the measurement and recording of blood pressure and pulse, as well as the assessment of orthostatic hypotension following the guidelines from Taylor, Lynn, and Bartlett's 10th edition. It also includes information on assessing blood pressure and nursing responsibilities.
