,Q. 4.4. A physical assessment of a 28-year-old female patient indicates that her blood pressure in her
legs is lower than that in her arms & that her brachial pulse is weaker in her left arm than in her right.
In addition, her femoral pulses are weak bilaterally. Which of the following possibilities would her care
provider be most likely to suspect? (Points : 0.4)

Q. 5.5. A 6-year-old boy has been brought to the emergency department by ambulance after his
mother discovered that his heart rate was “so fast I couldn't even count it.” The child was determined
to be in atrial flutter & his mother is seeking an explanation from the health care team. Which of the
following points should underlie an explanation to the mother? (Points : 0.4)
The child is experiencing a reentry rhythm in his right atrium.
The resolution of the problem is dependent on spontaneous recovery & is resistant to pacing
interventions.
The child is likely to have a normal ECG apart from the rapid heart rate.
The boy's atria are experiencing abnormal sympathetic stimulation.
Q. 6.6. A 66-year-old patient's echocardiogram reveals a hypertrophied left ventricle, normal chamber
volume, & a normal ejection fraction from the heart. What is this patient's most likely
diagnosis? (Points : 0.4)
Q. 7.7. A 70-year-old male patient presents to the emergency department complaining of pain in his
calf that is exacerbated when he walks. His pedal & popliteal pulses are faintly palpable & his leg distal
to the pain is noticeably reddened. What would his care provider's preliminary diagnosis & anticipated
treatment most likely be?(Points : 0.4)

A 44-year-old man awaiting a kidney transplant who requires hemodialysis three times per week
A 66-year-old woman with poorly controlled angina & consequent limited activity tolerance
Q. 11.11. A patient is experiencing impaired circulation secondary to increased systemic arterial
pressure. Which of the following statements is the most relevant phenomenon?(Points : 0.4)
Increased preload due to vascular resistance
High afterload because of backpressure against the left ventricle
Impaired contractility due to aortic resistance
Systolic impairment because of arterial stenosis
, Q. 12.12. A number of patients have presented to the emergency department in the last 24 hours with

Q. 13.13. A formerly normotensive woman, pregnant for the first time, develops hypertension &
headaches at 26 weeks' gestation. Her blood pressure is 154/110 mm Hg & she has proteinuria. What
other labs should be ordered for her? (Points : 0.4)
Q. 14.14. An older adult female patient has presented with a new onset of shortness of breath, & the
patient's nurse practitioner has ordered measurement of her BNP levels along with other diagnostic
tests. What is the most accurate rationale for the nurse practitioner's choice of blood work? (Points :
0.4)
BNP is released as a compensatory mechanism during heart failure & measuring it can help
differentiate the patient's dyspnea from a respiratory pathology.
BNP is an indirect indicator of the effectiveness of the RAA system in compensating for heart failure.
BNP levels correlate with the patient's risk of developing cognitive deficits secondary to heart failure
& consequent brain hypoxia.
BNP becomes elevated in cases of cardiac asthma, Cheyne-Stokes respirations, & acute pulmonary
edema, & measurement can gauge the severity of pulmonary effects.
Q. 15.15. The nurse practitioner for a cardiology practice is responsible for providing presurgical
teaching for patients who are about to undergo a coronary artery bypass graft. Which of the following
teaching points best conveys an aspect of the human circulatory system? (Points : 0.4)
