MN 551 Unit 3 Quiz Questions and Ans

Question 1

Which of the following situations related to the transition from fetal to perinatal circulation would be most likely to necessitate medical intervention?

Question options:

  • Pulmonary vascular resistance, related to muscle regression in the pulmonary arteries, rises over the course of the infant’s first week.
  • Systemic vascular resistance and left ventricular pressure are both increasing.
  • Alveolar oxygen tension increases, causing reversal of pulmonary vasoconstriction of the fetal arteries.
  • Pressure in the pulmonary circulation and the right side of the infant’s heart fall markedly.

Question 2

A 55-year-old male who is beginning to take a statin drug for his hypercholesterolemia is discussing cholesterol and its role in health and illness with his nurse practitioner. Which of the following aspects of hyperlipidemia would the nurse practitioner most likely take into account when teaching the patient?

Question options:

  • Hyperlipidemia is a consequence of diet and lifestyle rather than genetics.
  • HDL cholesterol is often characterized as being beneficial to health.
  • Cholesterol is a metabolic waste product that the liver is responsible for clearing.
  • The goal of medical treatment is to eliminate cholesterol from the vascular system.

Question 3

As part of the diagnostic workup for a male patient with a complex history of cardiovascular disease, the care team has identified the need for a record of the electrical activity of his heart, insight into the metabolism of his myocardium, and physical measurements, and imaging of his heart. Which of the following series of tests is most likely to provide the needed data for his diagnosis and care?

Question options:

  • Cardiac catheterization, cardiac CT, exercise stress testing
  • Serum creatinine levels, chest auscultation, myocardial perfusion scintigraphy
  • Ambulatory ECG, cardiac MRI, echocardiogram
  • Echocardiogram, PET scan, ECG

Question 4

A patient has suffered damage to his pericardium following a motor vehicle accident. Which of the following consequences should the nurse practitioner be most likely to rule out?

Question options:

  • Impaired physical restraint of the left ventricule
  • Increased friction during the contraction/relaxation cycle
  • Reduced protection from infectious organisms
  • Impaired regulation of myocardial contraction

Question 5

An older adult female patient has presented with a new onset of shortness of breath, and 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?

Question options:

  • BNP becomes elevated in cases of cardiac asthma, Cheyne-Stokes respirations, and acute pulmonary edema, and measurement can gauge the severity of pulmonary effects.
  • BNP levels correlate with the patient’s risk of developing cognitive deficits secondary to heart failure and consequent brain hypoxia.
  • BNP is an indirect indicator of the effectiveness of the RAA system in compensating for heart failure.
  • BNP is released as a compensatory mechanism during heart failure and measuring it can help differentiate the patient’s dyspnea from a respiratory pathology.

Question 6

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?

Question options:

  • “Your blood pressure varies widely between arteries and veins, and between pulmonary and systemic circulation.”
  • “Only around one quarter of your blood is in your heart at any given time.”
  • “Blood pressure and blood volume roughly mimic one another at any given location in the circulatory system.”
  • “Left-sided and right-sided pumping action at each beat of the heart must equal each other to ensure adequate blood distribution.”

Question 7                   1 / 1 point

A nurse practitioner is instructing a group of older adults about the risks associated with high cholesterol. Which of the following teaching points should the participants try to integrate into their lifestyle after the teaching session?

Question options:

  • “Remember, the ‘H’ in HDL and the ‘L’ in LDL correspond to high danger and low danger to your health.”
  • “Having high cholesterol increases your risk of developing diabetes and irregular heart rate.”
  • “Smoking and being overweight increases your risk of primary hypercholesterolemia.”
  • “Your family history of hypercholesterolemia is important, but there are things you can do to compensate for a high inherited risk.”

Question 8

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 and his mother is seeking an explanation from the health care team. Which of the following points should underlie an explanation to the mother?

Question options:

  • The boy’s atria are experiencing abnormal sympathetic stimulation.
  • The child is likely to have a normal ECG apart from the rapid heart rate.
  • The resolution of the problem is dependent on spontaneous recovery and is resistant to pacing interventions.
  • The child is experiencing a reentry rhythm in his right atrium.

Question 9

A 68-year-old male complains to his nurse practitioner that when he tests his blood pressure using a machine at his pharmacy, his heart rate is nearly always very low. At other times, he feels that his heart is racing, and it also seems to pause at times. The man has also occasionally had lightheadedness and a recent syncopal episode. What is this patient’s most likely diagnosis and the phenomenon underlying it?

Question options:

  • Ventricular arrhythmia as a result of alternating vagal and sympathetic stimulation
  • Sick sinus syndrome as a result of a disease of his sinus node and atrial or junctional arrhythmias
  • Premature atrial contractions that vacillate between tachycardic and bradycardic episodes as a consequence of an infectious process
  • Torsades de pointes as a result of disease of the bundle of His

Question 10

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 and popliteal pulses are faintly palpable and his leg distal to the pain is noticeably reddened. What would his care provider’s preliminary diagnosis and anticipated treatment most likely be?

Question options:

  • Giant cell temporal arteritis that will be treated with corticosteroids
  • Atherosclerotic occlusive disease necessitating thrombolytic therapy
  • Raynaud disease that will require antiplatelet medications
  • Acute arterial occlusion that will be treated with angioplasty
