a- lying flat in bed
b- left side-lying
c- in high fowler's position
d- semi-fowler's position
A

c- in high fowler’s position

17
Q
Which of the following blood gas abnormalities is initially most suggestive of pulmonary edema?
a- anoxia
b- hypercapnia
c- hyperoxygenation
d- hypocapnia
A

d- hypocapnia

decreased CO2 levels due to hyperventilation

18
Q
Which of the following actions is the appropriate initial response to a client coughing up pink, frothy sputum?
a- call for help
b- call the physician
c- start an I.V. line
d- suction the client
A

a- call for help

classic sign of acute pulmonary edema

19
Q
Which of the following terms describes the force against which the ventricle must expel blood?
a- afterload
b- cardiac output
c- overload
d- preload
A

a- afterload

refers to the resistance normally maintained by the aortic and pulmonic valves

20
Q
After recovery from an episode of acute pulmonary edema, why would an angiotensin-converting enzyme (ACE) inhibitor be administered?
a- promote diuresis
b- increase contractility
c- decrease contractility
d- reduce blood pressure
A

d- reduce blood pressure

21
Q
Acute pulmonary edema caused by heart failure is usually a result of damage to which of the following areas of the heart?
a- left atrium
b- right atrium
c- left ventricle
d- right ventricle
A

c- left ventricle

if left ventricle is damaged, output decreases & fluid accumulates in interstitial & alveolar spaces

22
Q
How quickly can an episode of acute pulmonary edema develop?
a- minutes
b- 1/2 hour
c- 1 hour
d- 3 hours
A

a- minutes

23
Q
Which of the following terms is used to describe the amount of stretch on the myocardium at the end of diastole?
a- afterload
b- cardiac index
c- cardiac output
d- preload
A

d- preload

the volume of the ventricle at the end of diastole determines preload

24
Q
Antihypertensives should be used cautiously in clients taking which of the following drugs?
a- ibuprofen
b- diphenhydramine
c- thioridazine
d- vitamins
A

c- thioridazine

thioridazine affects neurotransmitter norepinephrine which causes hypotension & other cardiovascular effects

25
``` One hour after administering IV furosemide to a client with heart failure, a short burst of ventricular tachycardia appears on the cardiac monitor. Which of the following electrolyte imbalances should the nurse suspect? a- hypocalcemia b- hypermagnesemia c- hypokalemia d- hypernatremia ```
c- hypokalemia | furosemide is a potassium depleting diuretic. hypokalemia increases myocardial excitability
26
An 18 year old client who recently had an upper respiratory infection is admitted with suspected rheumatic fever. Which assessment findings confirm this diagnosis? a- Erythema marginatum, sub-Q nodule & fever b- tachycardia, finger clubbing, loud S2 sound c- dyspnea, cough, palpitations d- dyspnes, fatigue & syncope
a- Erythema marginatum, sub-Q nodule & fever
27
``` A client is receiving spironolactone to treat HTN. Which of the following instruction should the nurse provide? a- eat foods high in potassium b- take daily potassium supplements c- discontinue sodium restrictions d- avoid salt substitutes ```
d- avoid salt substitutes | spironolactone is potassium sparing diuretic, salt substitutes are high in potassium
28
``` A 7 year old client is brought to the ED. He's tachypneic & afebrile & has a respiratory rate of 36 & a nonproductive cough. He recently had a cold. From this Hx, the client may have which of the following conditions? a- acute asthma b- bronchial pneumonia c- COPD d- emphysema ```
a- acute asthma
29
``` Which of the following assessment findings would help confirm a diagnosis of asthma in a client suspected of having the disorder? a- circumoral cyanosis b- increased forced expiratory volume c- inspiratory & expiratory wheezing d- normal breath sounds ```
c- inspiratory & expiratory wheezing
30
``` Which of the following types of asthma involves and acute asthma attack brought on by an upper respiratory infection? a- emotional b- extrinsic c- intrinsic d- mediated ```
c- intrinsic | intrinsic asthma doesn't have an easily identifiable allergen & can be triggered by the common cold
31
``` A client with acute asthma showing inspiratory & expiratory wheezes & a decreased forced expiratory volume should be treated with which of the following classes of medication right away? a- beta-adrenergic blockers b- bronchodilators c- inhaled steroids d- oral steroids ```
