NHA MODULE 7- POINT OF CARE TESTING AND
LABORATORY PROCEDURES
What causes the pain that occurs with myocardial ischemia?
A. death of myocardial tissue
b. dysrhythmias caused by cellular irritability
c. lactic acid accumulation during anaerobic metabolism
d. increased pressure in the arteries and pulmonary vessels - Answers - C
In the patient with chest pain, which results distinguish unstable angina from an MI?
a. serum troponin levels increased 4-6 hours after onset of pain
b. a chest xray showing left ventricular hypertrophy
c. CK-MB elevations that peak 6 hours after the infarct
D. ECG changes present at the onset of pain - Answers - A
What should the nurse teach women about CAD?
a. estrogen replacement in postmenopausal women decreases risk of CAD
b. cholesterol levels are not as significant a risk factor for women as men
c. CAD is the leading cause of death in women
d. women typically have substernal crushing chest pain - Answers - C
Which drugs should the nurse anticipate for clients with mechanical valves?
a. nitrates
b. antidysrhythmics
c. beta blockers
d. anticoagulants - Answers - D
which diagnostic test is most useful in differentiating dyspnea related to pulmonary
effects of HF versus dyspnea related to pulmonary disease?
a. stress test
b. cardiac catheterization
c. BNP levels
d. echocardiogram - Answers - C
explanation: if someone is SOB and trying to figure out if it's related to HF or lung
disease, the BNP will tell you if it's heart failure
a client with chest pain is admitted to the ED and all of the following items are ordered.
which one should be completed first?
, a. chest x-ray
b. troponin level
c. electrocardiogram
d. insertion of peripheral IV - Answers - C
explanation: takes 30 seconds to a minute to do and it will give you very important
information about the patient's heart
a nurse is caring for a client receiving IV lasix and morphine for decompensated heart
failure with orthopnea. Which clinical finding is the best indicator that the treatment has
been effective?
a. weight loss of 2lb in 24 hours
b. hourly urine output of 50 mL
c. client denies chest pain or pressure
d. reduced dyspnea with HOB at 30 degrees - Answers - D
explanation: it is measurable - indicator that HOB is all the way down to 30 degrees and
client is getting better
what are manifestations of Acute Coronary Syndrome? select all that apply
a. dysrhythmia
b. stable angina
c. unstable angina
d. ST segment elevation MI (STEMI)
e. non-ST segment elevation MI (non-STEMI) - Answers - A, C, D, E
in the patient with SVT, which assessment indicates decreased CO?
a. dyspnea and HTN
b. palpitations and chest pain
c. tachypnea and abdominal distention
d. bounding pulses and systolic murmur - Answers - B
remember: palpitations and chest pain are results of decreased CO!!!!
what is the most common finding in people at risk for sudden cardiac death?
a. mitral valve stenosis
b. left ventricular dysfunction
c. atherosclerotic heart disease
d. aortic valve disease - Answers - B
a client with no history of cardiovascular disease comes into the ambulatory clinic with
flu-like symptoms. the client suddenly complains of chest pain. which of the following
