Module 4 Flashcards
What is the normal range of temperature?
35.8 to 37.3 degrees Celsius (Rectal: 0.4 to 0.5 degrees Celsius higher)
What is the normal Resting heart rate in adults?
50-95 is normal resting heart rate for adults
Normal resting respiratory rate =
10 to 20 breaths per minute
What is systolic pressure?
the maximum pressure on the arteries during left ventricular contraction
What is diastolic pressure?
the resting pressure on the arteries between each cardiac contraction.
a pulse oximeter measures
measures light absorption of hemoglobin and represents arterial SpO2
A healthy patient will have oxygen saturation of
SpO2 of ≥ 97%.
Assessing physical appearance includes
Age, sex, level of consciousness, skin color, facial features
Assessing body structure includes
Stature (height), Nutrition, symmetry, posture, position, and bodybuilder, contour
Assessing mobility includes
Gait, range of motion
Assessing behaviour includes
Facial expression, mood and affect, speech, dress, personal hygiene
How do you measure BMI?
= weight (kg)/height (metres)2
OR lbs/in 2 x 703
The waist to hip ratio reflects
Body fat distribution as an indicator of health risk
= Waist circumference/hip circumference
Cellular metabolism requires mean stable core (“deep body”) temperature of
37.2 c (99F)
Assessing the pulse includes
Rate, rhythm, force, and equality (when comparing pulses bilaterally)
The normal resting heart range of 95% of healthy persons is
50 - 95 bpm
In adults, a resting heart rate less than 50 bpm is called
Bradycardia
The force of the pulse shows
The strength of the hearts stroke volume
The pulse force is recorded on a three point scale… which looks like
3+ Full, bounding
2+ Normal
1+ weak, threads
0 Absent
The pulse pressure is the
Difference between the systolic and diastolic pressures and reflects the stroke volume
The level of BP is determined by five factors. What are they
Cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, elasticity of vessel walls
What is phase 1 of Korotkoff sounds?
The first appearance of faint, repetitive, clear TAPPING sounds which gradually increase in intensity for at least two consecutive beats is the systolic blood pressure.
What is phase 2 of Korotkoff sounds?
brief period may follow during which the sounds soften and acquire a SWISHING quality.
What is phase 3vof Korotkoff sounds?
The return of sharper sounds (KNOCKING), which become crisper to regain, or even exceed, the intensity of phase I sounds.
What is phase 4 of Korotkoff sounds?
The distinct ABRUPT MUFFLING of sounds, which become soft and blowing in quality.
What is phase 5 of Korotkoff sounds?
The point at which all sounds finally disappear completely is the diastolic pressure
When BP measured at the arm is excessively high, Compare it with the five pressure to check for
Coarctation Of the aorta (a congenital form of narrowing)
Temperature is a
Feedback mechanism regulated by the hypothalamus
What are some influencers on temperature
Diurnal cycle, Menstrual cycle, age, Exercise
What is mean arterial pressure?
GPressure forcing blood into tissues
Hypotension is (in measurement)
> 95/60
Pre-hypertension is
130-139 and 80-89
Stage one hypertension is
140-159 and 90-99
Stage two hypertension is
> 160 systolic and >100 diastolic
What are the five factors the level of BP is determined by?
Cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, elasticity of vessel walls
