... [Show More] or answers the question.
____ 1. A patient is prescribed to have capillary blood glucose readings every four hours. What should the nurse
include when explaining capillaries to the patient?
1) It is a low-pressure vascular circuit.
2) Capillaries are the largest vessel within the arterial system.
3) The real work of the vascular system occurs at the capillary level.
4) They are flexible to adapt to changes in volume without large changes in pressure.
____ 2. While auscultating a patient’s heart rate the nurse hears scratching sounds. What is most likely causing this
sound?
1) Epicardium adhering to the heart surface
2) Low level of fluid in the pericardial cavity
3) Parietal pericardium adhering to the sternum
4) Endocardium adhering to the heart chambers
____ 3. The nurse is reviewing the anatomy of the heart with a patient scheduled for cardiac surgery. Which patient
statement indicates additional teaching is required?
1) “Oxygenated blood returns to the left atrium through the pulmonary vein.”
2) “The right atrium receives blood from the superior and inferior vena cava.”
3) “Blood leaves the right ventricle and travels through the pulmonary vein to the lungs.”
4) “Blood leaves the right ventricle and travels through the pulmonary artery to the lungs.”
____ 4. The nurse is preparing teaching about the coronary arteries for a group of patients scheduled for heart surgery.
Which information should the nurse include in this teaching?
1) The coronary arteries originate in the cusps of the aortic valve.
2) The coronary arteries prevent the backflow of blood into the atria.
3) The coronary arteries respond to changes in pressure within the heart.
4) The coronary arteries prevent the backflow of blood into the ventricles.
____ 5. The nurse notes that a patient has a low serum potassium level. Which phase of the cardiac action potential
will be most affected by this blood level?
1) Phase 0
2) Phase 1
3) Phase 3
4) Phase 4
____ 6. A patient’s QRS complex is becoming increasingly wider. What is occurring within the heart muscle that is
reflected on this tracing?
1) The ventricles are repolarizing.
2) Atrial repolarization is occurring.
3) Ventricular depolarization is prolonged.
4) The atria depolarize and the impulse at the AV node is delayed.
____ 7. A patient with a blood pressure of 88/50 mm Hg has a heart rate of 112 beats per minute. Which mechanism
should the nurse realize is occurring in this patient?
1) Positive chronotropic effect
2) Negative chronotropic effect
3) Force of the mechanical contraction
4) Reaction to ventricular volume at the end of diastole
____ 8. The nurse suspects that a patient is experiencing a release of norepinephrine from the adrenal medulla. Which
assessment finding did the nurse use to make this clinical decision?
1) Blood pressure 94/48 mm Hg 3) Heart rate 120 beats per minute
2) Heart rate 68 beats per minute 4) Blood pressure 180/100 mm Hg
____ 9. The nurse is preparing to determine a patient’s cardiac output. Which measurement should be used for
preload?
1) Heart rate 3) Oxygen saturation
2) Blood pressure 4) Central venous pressure
____ 10. A patient’s blood pressure is 174/98 mm Hg. Which aspect of cardiac output is most affected by this elevated
reading?
1) Preload 3) Afterload
2) Heart rate 4) Contractility
____ 11. The nurse notes that a patient has bilateral lower extremity edema. For which health problem should the nurse
assess further?
1) Pericarditis 3) Lymph obstruction
2) Cardiac tamponade 4) Venous insufficiency
____ 12. After palpating a patient’s radial pulses, the nurse proceeds to palpate the brachial, carotid, femoral, popliteal,
and posterior tibial pulses. What condition caused the nurse to make this more thorough physical assessment?
1) Skin warm and dry 3) Edema of the left lower extremity
2) Various skin temperatures 4) Respiratory rate of 24 and labored
____ 13. The nurse is preparing to auscultate the heart sounds of a patient with mitral valve regurgitation. Which sound
should the nurse expect to hear?
1) Rub 3) Murmur
2) Click 4) Atrial gallop
____ 14. A patient is being assessed for heart disease. For which laboratory test should the nurse instruct to avoid
eating and drinking fluids for 12 hours?
1) Lipid panel 3) C-reactive protein
2) Homocysteine 4) Partial thromboplastin time
____ 15. The nurse notes that a patient is scheduled for a brain natriuretic peptide level to be drawn. What patient
teaching should the nurse prepare for this patient?
1) Low-fat diet 3) Symptoms of a heart attack
2) Signs of heart failure 4) Lung versus heart problems
____ 16. A patient is scheduled for a transesophageal echocardiogram (TEE). What information should the nurse
expect to be provided from this test?
1) Cardiac filling pressures 3) Heart function during stress
2) Integrity of cardiac arteries 4) Presence of clots in the atria
____ 17. A patient is recovering from a cardiac catheterization. For which finding should the nurse notify the healthcare provider?
1) Warm right foot 3) Discomfort lying flat for six hours
2) Urine output 250 mL/2 hours 4) Hematoma formation at puncture site [Show Less]
