Q

A client comes in running late and mentions how stressed they are about not being there on time and how much they have to do later that day. What will you take into account when measuring their vital signs?

A

Stress can lead to an increased body temperature so if she measures slightly higher than expected this could be a contributing factor.

Other factors that effect temp include:

  • disease state
  • exercise
  • environment
  • hormone levels
  • circadian rhythm
  • age

Q

How does a fever act as a defense mechanism?

A

Up to 38:

  • enhances the body’s immune system
  • during febrile episode white blood cell production is stimulated
  • reduction in conc. of iron in the blood plasma, suppresses growth of bacteria
  • stimulates production of interferon, fights viruses

Q

List some advantages and disadvantages of taking an oral temperature.

A

Advantages:
non invasive, inexpensive, accurate, easy
Disadvantages:
at the whim of the temp of food/drink they’ve consumed, limited population (ability to follow instruction), if they smoke could be effected, not core

Q

What is Bradycardia?

A

<60bpm

21
Q

What is Tachycardia?

A

> 100bpm

22
Q

What is Dysrhythmia/Arrhythmia?

A

abnormal rhythm

23
Q

What is sinus arrhythmia?

A

variation with the respiratory cycle (heart speeds up when you inhale and slows down when you exhale)
-normal in children and young adults

24
Q

What is a pulse deficit?

A

The difference between apical and radial pulse.

25
Q

What is respiration?

A

the mechanism used by the body to exchange gases between the atmosphere, blood, and the cells

26
Q

Your measuring a newborn resp. rate in the obstetrical unit and get a rate of 28 breaths/min. Should you be concerned?

A

Yes! Measure again for accuracy. Expected resp rate for newborns is 30-60.
12-20 is expected in adults

27
Q

Name 4 factors that could increase resp rate.

A
  1. exercise
  2. acute pain
  3. anxiety
  4. smoking
28
Q

Your client was practicing for baseball try outs and was clocked in the head, how may this effect resp rate? Select all that apply.

a) decreased rate
b) alters rhythm
c) increases depth
d) shallower/quicker

A

Both a and b

29
Q

What are you assess when assessing resp. rate.

A
  1. rate
  2. depth (deep, normal, shallow)
  3. rhythm (regular or irregular)
  4. sound (digression from normal or effortless)
30
Q

What is Bradypnea?

A

<12 breaths/min

31
Q

What is Tachypnea?

A

> 20 breaths/min

32
Q

What is Hyperpnea?

A

laboured, increased depth and rate

33
Q

What is Apnea?

A

pauses in breathing

34
Q

What is Dyspnea?

A

difficulty breathing or breathless

35
Q

Accurate measurement of respirations requires _________________________ and _____________________ of the chest wall movement.

A

Observation, palpation

36
Q

What is blood pressure?

A

The force of blood pushing against the side of the vessel wall. Indicator of cardiovascular health.

37
Q

What is systolic pressure?

A

The max pressure felt in an artery during ventricular contraction

38
Q

What is diastolic pressure?

A

Elastic recoil, resting pressure that blood exerts between each contraction

39
Q

Your client, George, a moderately active accountant, measures in with a blood pressure of 90/70. What would you refer to this as?

A

 Optimal: <120/<80 mmHg Normal: <135/<85 mmHg Hypotension: <90/anything? Hypertension: >140/90

40
Q

Name 5 factors that effect BP

A 
Cardiac output (volume of blood that flows from the heart to the ventricles)

Elasticity of vessel walls
Blood Volume
Age
Stress
Viscosity of blood
Ethnicity
Smoking
Medications
Daily variation
41
Q

What are some ways to assess BP?

A

BP devices (manual or automatic)
Arterial lines
Auscultation with stethoscope and sphygmomanometer

42
Q

How should you size a blood pressure cuff?

A

40% of the width of the arm

2/3 of arm covered

43
Q

An auscultatory gap is when sounds disappear during BP auscultation for _____mmHg

A

10-40 at any point during auscultation

44
Q

What is pain?… other than studying for this course

A

Pain is an unpleasent sensory and emotional experience associated with actual or potential damage

45
Q

How to assess for pain?

A 
History of current pain (subjective, PQRSTU-AAA)
P- provocative/precipitating factors
Q- quality
R- region/radiation
S- severity
T- timing
A- aggravating factors
A- associated symptoms
A- alleviating factors
46
Q

What are the two types of sphygamomanometers?

A
  1. Aneroid- subject to drift, must be recalibrated once a year to rest at zero, inexpensive and lightweight
  2. Mercury- must be read at eye level, doesn’t require readjustment, but mercury is bulky and dangerous
47
Q

What are the Korotkoff sounds?

A

The sounds auscultated during blood pressure measurement.
I- soft, clear tapping, increasing in intensity
II- swooshing, soft murmur that follows tapping
III- knocking, crisp, high pitched sounds
IV- abrupt muffling, muting of sounds to a low-pitched, cushioned murmur, blowing
V- SILENCE

48
Q

Your older nurse mentor says that automatic BP cuffs are the best way to go, but you in all your student wisdom know that manual BP cuff do have their virtues. What are some pros and cons to automatic BP cuffs?

A

Advantages: fast, accurate, non-invasive
Disadvantages: Cannot sense vibrations of low BP or rapidly irregular pulses, as in atrial fibrillation, must be properly calibrated for accurate readings
