Chapter 28 - Assessment of CardiovascularFunction
Answer: C
Rationale: Excessive fatigue is not normal and may
indicate the onset of heart failure. While physical
activity should be continued, even if healthy, a
new strenuous exercise regime should be carefully
monitored. - ANS-What information should be in the teaching plan of a
76-year-old patient after a physical?
A. Initiating a new strenuous exercise regimen is
recommended.
B. Limit physical activity and exercise.
C. Report any new or excessive fatigue.
D. Excessive fatigue is not unusual as you age.
Answer: C
Rationale: Avoiding stress at the cannula insertion site
by maintaining flat bed rest helps reduce the incidence of
bleeding. Encouraging fluids helps clear the contrast dye. - ANS-What is an important nursing
action post cardiac
catheterization interventions?
A. Early mobilization to prevent clot formation
B. Fluid restriction to avoid fluid overload
C. Bedrest to avoid stress on cannula insertion site
D. Head of bed at 30 degrees for respiratory support
Answer: A
Rationale: Coronary angiography is done to specifically evaluate the coronary arteries. Stress
testing evaluates heart functioning during times of increased
workload. Right heart catheterization evaluates cardiac
filling pressures, cardiac output, and valvular function.
Transesophageal echo evaluates the posterior aspect of
the heart and the presence of clots. - ANS-What is the most likely procedure to determine
the cause of severe chest pain in the patient newly
admitted to the hospital?
A. Coronary angiography
B. Nuclear stress testing
C. Right heart catheterization
D. TEE
, Answer: A, C, and E
Rationale: Smoking, exercise, and alcohol intake
are modifiable risk factors for heart disease. Patients
should not be told to drink lots of water as the heart
may not be able to handle excessive fluids. A diet rich
in red meat is a risk factor - ANS-A nurse is providing care for a patient newly
diagnosed with heart disease. Which dietary, activity,
or lifestyle modification(s) should be included in the
plan of care? (Select all that apply.)
A. Stop smoking.
B. Drink lots of water.
C. Limit sedentary lifestyle.
D. Eat a diet rich in red meat protein.
E. Limit alcohol.
Answer: B
Rationale: Hypertension increases resistance. Increase
resistance may decrease cardiac output. Decreased
resistance may increase cardiac output. - ANS-A patient with hypertension has which physical
symptom?
A. Decreased resistance, which may increase CO
B. Increased resistance, which may decrease CO
C. Increased resistance, which may increase CO
D. Decreased resistance, which may decrease CO
Answer: C
Rationale: The electrical conduction system is controlled by the movement of charged ions
across the
cell membrane, has a negative resting membrane
potential, and is composed of cells with the property
of automaticity, which is reflected in the waveforms
on the electrocardiogram. - ANS-Which is true of the electrical conduction system of the
heart?
A. It is primarily controlled by the movement of
uncharged ions.
B. It has a positive resting membrane potential.
C. It is reflected in the waveforms on the
electrocardiogram.
D. It requires cells that respond only to stimulus from
the autonomic nervous system.
Answer: A
Rationale: Flow through the heart is controlled
through changes in pressure, not oxygen. The
