miscellaneous Jackie nonsense

Question 1

S/S of heart failure

Answer 1

SOB, fatigue, weakness, swelling of legs, feet or abdomen, rapid or irregular heart beat, **S3 or S4 sounds, persistent cough or ** wheezing, wt gain c fluid retention

Question 2

Indication of HTN

Answer 2

SBP >or = 140 mmHg or DBP > or = 90 mmHg; S4 heart sound

Question 3

Exercise prescription for HTN

Answer 3

30 min/d most days of the week; maintain BMI b/w 18.5-24.9

Question 4

Bronchiectasis- s/S & description

Answer 4

Progressive obstructive lung disease that produces abnormal dilation of bronchus
S/s: consistent productive cough, hemoptysis, wt loss, anemia, crackles, wheezes, loud breath sounds

Question 5

Change in FEV1 that indicates asthma after bronchodilator

Answer 5

after bronchodilator Rx FEV1 is improved by 15%

Question 6

O2 therapy requirements

Answer 6

Pa02 55 mmHg or O2 sat 88%
Or
Pa02 55-59mmHg or 02 sat 89% c for pulmonary or polycythemia

Question 7

Measurement difference (cm) b/w affected vs non-affected UE indicates lymphedema?

Answer 7

2-3cm difference

Question 8

MI EKG changes

Answer 8

ST elevation (acute transmural infarct) & T-wave inversion (STEMI)
Or NSTEMI

Question 9

sign on EKG of ischemia

Answer 9

ST depression

Question 10

What % indicates obstructive impairment on Pulmonary function test (FEV1/FVC)

Answer 10

< 70%

Question 11

Formula for rate pressure product (RPP)

Answer 11

RPP = SBP x HR

Used for angina patients

Question 12

Upper limit of prescribed training HR early in cardiac rehab

Answer 12

11-13 RPE

Question 13

Represents 70% HR max on RPE (on 20 point scale)

Answer 13

13-14

Question 14

Normal inspiratory: expiration ration

Answer 14

1:2 (inspiration 1/2 a long as expiration)

Question 15

Inspiration: expiration ratio for COPD

Answer 15

I:E- 1:3 or 1:4

Takes longer for COPD pt to expel air

Question 16

Karvonen formula

Answer 16

[(HR max-HR rest)x Intensity] - HR rest
Lower target HR= [(HR max-HR rest)x .40% ] - HR rest
Higher target HR = [(HR max-HR rest)x 85%] - HR rest

Question 17

Linear change in SBP c inc in workload during acute aerobic exercise (mmHg/MET)?

Answer 17

8-12 mmHg/MET

Question 18

Difference b/w Atelectasis vs PTX

Answer 18

Atelectasis is alveolar collapse or deflated, under ventilated.
vs
PTX is lung collapse

Question 19

Cardiac Output formula & L/min at rest

Answer 19

CO = HR x SV

5.0-5.5 L/min

Question 20

S1 heart sound

Answer 20

Mitral & tricuspid value shut

Question 21

S2 heart sound

Answer 21

Pulmonary and aortic valves shut

Question 22

Ventilation/Perfusion ratio (V/Q ratio)

Answer 22

Ratio of pulmonary alveolar ventilation to pulmonary capillary perfusion

Question 23

Negative pressure

Answer 23

• generated and maintained by a ventilation system that removes more exhaust air from the room than air is allowed into the room.
  Ex/ isolate patients with airborne contagious diseases such as tuberculosis, measles, or chickenpox

Question 24

Positive pressure rooms

Answer 24

• Air pressure in the room under positive pressure is higher than outside, so contaminants (particles, viruses, bacteria) are kept out.
• positive pressure environment is used to protect patients in operating theatres, so that infection does not enter open body cavities, and to protect patients with HIV infection, or other conditions linked to a compromised immune system, being nursed in isolation rooms.
