And Answers
the nurse suspects a pt with dark skin is hypoxic. which area would the nurse check to help
confirm this conclusion?
1. eye sclera
2. skin
3. mucous membranes
4. chest - ANS answer = 3
in pts with deeply pigmented skin, these color changes can be seen in the nail beds or mucous
membranes of the mouth
a pts SA and AV nodes have failed to fire. which of these results should the nurse expect as the
ventricles take over and initiate impulses? (SATA)
1. change in LOC
2. hypertension
3. dyspnea
4. bounding peripheral pulses
5. tachycardia - ANS answer = 1 & 3
when SA and AV nodes fail to fire, the ventricles initiates impulses at a rate of 20-40 bpm ...
changes in LOC is caused b inadequate cardiac output; hypotension would occur; dyspnea bc
ventrical rate is not fast enough to meet body's O2 demands; bradycardia would also be present
the nurse is assess a pt with heart failure. what should the nurse expect to hear upon
auscultating lung sounds?
1. wheezing
2. pleural friction rub
3. rhonchi
4. crackles - ANS answer = 4
crackles are a clinical finding of HF. wheezing is heard with asthma; pleural friction rub is heard
with pneumonia, pleural effusion or PE; and rhonci is not a clinical finding in HF.
a pt presents to the ED with chest pain. which blood study is most important to monitor to rule
out a mycardial infarction (MI)?
1. complete blood count
2. cardiac troponin
3. kidney function tests
4. potassium level - ANS answer = 2
cardiac troponin level is drawn to detect cardiac damag, this is more effective than a CK-MB.
, CBC may be drawn but not used to rule out MI; kidney function tests aren't used to dx a MI;
potassium level will be checked but an abnormal level doesn't reveal cardiac damage, a K+
abnormality will show up on an ECG
which of the following is most common cause of left sided heart failure?
1. hypertension
2. kidney failure
3. mitral stenosis
4. aortic regurgitation - ANS answer = 1
high blood pressure is the number 1 cause of left sided HF
kidney failure doesn't cause HF directly; mitral stenosis is not the most common cause; aortic
regurgitation isn't the most common cause
the nurse is caring for a pt with HF who has a pattern of shallow respirations building to deep
breaths, followed by apnea. which of the following does this describe?
1. kussmaul respirations
2. cheyne-stokes breathing
3. bradypnea
4. agonal breathing - ANS answer = 2
kussmauls is deep and labored breathing associtated with metabolic acidosis; bradypnea is
abnoramally slow breathing; agonal is characterized by gasping and labored breathing
which is the most common cause of right sided HF?
1. left sided HF
2. hypertension
3. infective endocarditis (IE)
4. aortic regurgitation - ANS answer = 1
a pt asks the nurse about the goal of heart failure treatment. which response by the nurse is
best?
1. to increase strength of heart's contraction while increasing workload
2. reduce amount of O2 delivered to the tisses and decrease heart's workload
3. improve heart's ability to pump and decrease O2 demands of heart
4. increase water and sodium in body while decreasing strength of heart's contractions - ANS
answer = 3
the nurse is caring for a pt with pulmonary edema. in which position should the nurse place the
pt?
1. fowler's
2. left side lying
3. prone
4. supine - ANS answer = 1 , this will reduce venous return
all the other choices will increase the venous return
