NUR 254 Test 1 Review# of alveoli perfused decreases as shock progresses. Hypoxemia and respiratory acidosis. If
this persists ARDS may develop. - ANS-respiratory S/S of progressive/ intermediate shock
<150 mg/dL - ANS-A patient is taking simvastatin for coronary artery disease. Which of the
following is the desired goal for triglycerides?
0.12- 0.20 seconds - ANS-WHAT IS THE NORMAL MEASUREMENT IN SECONDS FOR THE
PR INTERVAL?
0.5-2 ng/mL
give digibound if toxic
N/V/ visual disturbances - ANS-normal digoxin level
0.6-0.10 seconds - ANS-WHAT IS THE NORMAL MEASURMENT IN SECONDS FOR THE
QRS COMPLEX?
1. Cardiac output
2. Vessel diameter and tone
3. Blood volume
4. Tissues ability to extract and use O2 - ANS-Four factors necessary to maintain cellular
metabolism. When one of these is disrupted, shock occurs.
1. Endothelial damage (smoking, HTN)
2. Hypercoagulability (obesity, hormones)
3. Stasis (immobility, polycythemia) - ANS-What are the three (3) components of Virchow's
Triad?
10-15 mmhg - ANS-In stage I of shock, compensatory mechanisms begin when there is a
volume loss of approximately 1000 mL which causes a MAP drop of __________ mmHg
11-16 seconds - ANS-Normal PT (prothrombin time)
2. bradycardia - ANS-A patient is involved in a MVC. Which finding would indicate neruogenic
shock as opposed to hypovolvemic shock?
1. Decreased hgb and hct
2. Bradycardia
,3. Tachycardia
4. Hypotension
5. Hypertension
2. increased lactic acid/ hyperkalemia - ANS-Which findings indicates progression from early (I)
to intermediate (II)?
1. decreased U/O
2. increased lactic acid/ hyperkalemia
3. fluid shift from interstitial space INTO capillaries
4. MAP drop 12 mmHg
20 seconds - ANS-Each large box on the ecg paper represents how many seconds
200 - ANS-The TLC (Therapeutic Lifestyle Change) diet is recommended by NCEP (National
Cholesterol Education Program). The recommendation is no more than how many mg of
cholesterol each day?
22 mmHg - ANS-Central venous pressure (CVP) monitoring provides information related to
preload. If a patient were experiencing heart failure after myocardial infarction which of the
following readings would indicate hypervolemia?
3 mmHg
0 mmHg
10 mmHg
22 mmHg
24-36 hours after the incident - ANS-when do troponins peak? After how many hours?
25 to 35 seconds - ANS-Normal PTT (partial thromboplastin time)
2nd intercostal space, right sternal border - ANS-A patient has a history of aortic stenosis and
has a murmur. This murmur would be best auscultated in what location?
30 minutes per day most days (5-6 days a week) - ANS-ULTIMATELY THE RECOMMENDED
GOAL FOR PHYSICAL ACTIVITY FOR CORONARY ARTERY DISEASE IS:
300mg - ANS-Initial dose of amiodarone bolus IV
, 40-60 BPM - ANS-If the sinoatrial (SA) node is unable to pace the heart due to damage, the
atrioventricular (AV) node will take over. What will the heart rate range be if this occurs?
5th intercostal space at midclavicular line - ANS-where would you place the V4 lead when doing
a 12 lead EKG?
5th intercostal space, left midclavicular line. - ANS-The nurse prepares to administer metoprolol,
to a patient with atrial fibrillation. This beta adrenenergic blocker is used to control heart rate for
this patient. When determining heart rate the nurse should assess an apical heart rate for 60
seconds. Where would the nurse auscultate?
6mg, 12 mg, 12mg rapid IV push - ANS-what are the doses for adenosine?
a patient that fell 3 days ago - ANS-A patient with myocardial infarction is ordered the fibrinolytic
streptokinase. Which of the following would contraindicate its use?
a. blood flow
b. oxygenation - ANS-Shock is a SYNDROME resulting from a decrease in
a. ____________, that causes inadequate
b. __________ resulting in ischemic organs/tissues that cannot carry out cellular metabolism.
ACS- acute coronary syndrome - ANS-THIS IS THE UMBRELLA TERM FOR UNSTABLE
ANGINA, THAT IS WORSE THAN TYPICAL ANGINA, LASTS GREATER THAN 15 MINUTES,
INDICATES MYOCARDIAL INJURY, AND IS OFTEN A PRECURSOR TO MYOCARDIAL
INFARCTION?
adenosine - ANS-The med is administrated rapid iv push resulting In a brief flatline, used for
SVT, code cart must be at bedside
Adequate cardiac output
Tissues must be able to extract and use oxygen
Blood vessel diameter and tone must be adequate
Blood volume must be adequate - ANS-In order for cells to "do their work" (cellular metabolism),
which of the following physiologic components must be working appropriately?
Adequate early stages. Heart rate increased, but BP normal. - ANS-cardiac S/S of
compensatory/ early shock
