33 Questions
What do vital signs provide information about?
The level of physical functioning
In what context should vital signs be interpreted?
In the context of the patient's condition
Which statement about changes in vital signs is true?
May be one of the few abnormalities found in disease
What is typically included when assessing a patient's vital signs?
Weight and height measurements
What is SpO2 a measure of?
Peripheral oxygen saturation
In assessing orthostatic blood pressures, what does a drop in systolic blood pressure upon standing suggest?
Hypotension
Which parameter is critical for evaluating a patient's respiratory function?
Pulse oximetry
Pulse rate, part of vital sign assessment, mainly reflects the functioning of which body system?
Cardiovascular system
Why are single measurements in the supine and standing postures considered an alternative in a busy practice?
Because it is quicker to perform than other measurement methods
Why is patient self-report not considered adequate for assessing height and weight?
Because self-reported height and weight can be inaccurate
What is the primary purpose of an oximeter in a medical setting?
To indirectly measure the oxygen level in the blood
What does a reading of 92% SpO2 on a pulse oximeter indicate?
Anywhere from 90% to 94% oxygen saturation in the blood
Why are vital signs referred to as 'vital'?
Because they are crucial indicators of the patient's overall health status
What is the formula to calculate Body Mass Index (BMI) according to the given text?
$Weight(kg)/Height (m^2)$
When should a healthcare professional treat the patient's vitals directly according to the text?
Only when it is necessary to treat the vitals directly
What does an oximeter primarily measure according to the text?
Oxygen level in the blood
What is the term used to describe the absence of respiration?
Apnea
Which respiratory pattern suggests dehydration, volume depletion, or other transient conditions rather than neurogenic orthostatic hypotension?
Bradypnea
Why is early recognition of abnormal respiratory patterns important?
To prevent further deterioration
What does the cerebrum contribute to in terms of respiration?
Controlling voluntary breathing
What should the initial assessment include when evaluating orthostatic blood pressures?
Checking heart rate and blood pressure after 5 minutes of standing
What does tachypnea refer to?
Increased respiratory rate
How do abnormal breathing patterns affect clinical intervention?
They aid in early intervention to prevent deterioration
Why is it important to measure orthostatic blood pressures after the patient has been supine for at least 5 minutes?
To detect immediate BP declines and risk for falls during standing up
What are the factors affecting body temperature that include metabolic processes, digestion, sleep, exercise, and ingestion of exogenous substances?
Digestion and ingestion of exogenous substances
Which method of temperature measurement is generally 0.7 degrees F higher than oral temperature?
Rectal
What is the standard considered as a fever in Fahrenheit?
100.4
Which of the following is NOT a cause of an elevated temperature?
Heat stroke
What is the normal range for adults' respiratory rate per minute?
12 - 20/min
Which factor does NOT affect the respiratory rate according to the text?
Pulse rate
What is considered the most accurate method of measuring core body temperature?
Rectal
Which parameter is NOT important to assess when evaluating respiration status according to the text?
Heart rate
What is the average normal axillary temperature based on the content provided?
$97.6^{ ext{o}F}$
