NRNP 6540 Exam | Complete Study Guide (Latest 2023) All Exams. A 74-year-old man presents to your office for a routine He has no present complaint His medical history is significant for right knee osteoarthritis He takes naproxen occasionally, to relieve knee pain. He does not smoke or consume alcohol His BP is 165/75 mm Hg and PR is 70/min. The physical examination showed a mild systolic ejection type murmur at the base of the heat to the right. An EKG revealed left ventricular hypertrophy and secondary ST segment and T wave change Moderate left ventricular hypertrophy, without any flow abnormalities, was demonstrated on echocardiography. The ejection fraction was 60%. What is the most probable cause of hypertension in this patient? A. Rigidity of the arterial wall B. Elevated plasma renin activity C. Aortic insufficiency D. Increased cardiac output E. Increased intravascular volume 2. A 32-year-old Caucasian female comes to the physician because of a one-week history of fatigue, progressive worsening of shortness of breath and swelling of feet. She denies any chest pain She has no other medical problems except a recent cold two weeks ago. She is not taking any medication Her temperature is 36 7 C (98 F), blood pressure is 110/65 mmHg, pulse is g0/min, and respirations are 20/min Bilateral basal crackles, elevated jugular venous pressure, and 2+ bilateral pitting edema of the ankles are noted Complete blood count is unremarkable. Transthoracic echocardiogram of her heat will most likely show? A. Concentric hypertrophy of the heart B. Eccentric hypertrophy of the heart C. Mitral stenosis D. Hypokinesia of the inferior wall E. Dilated ventricles with diffuse hypokinesia 3. A 47-year-old woman loses consciousness for 2 minutes while shopping in a supermarket. In the emergency room, she recounts feeling nausea and warmth spreading over her body immediately before passing out She has never had a similar episode before. She has not seen a doctor for several years and does not take any medications, nor does she use tobacco, alcohol or drug. Her family history is unremarkable. Which of the following most likely caused this episode? A. Cardiac arrythmia B. Seizure C. Neurocardiogenic syncope D. Heat valve disease E. Orthostatic hypotension 4. A 25-year-old woman experiences sudden-onset palpitations and generalized weakness. During this episode, her blood pressure is 100/60 mmHg and her heat rate is 160/min and regular. She has no significant past medical history and does not take any medications She reports having a few similar episodes in the past which she has self-treated by immersing her face in cold water Generally, she says, cold water immersion relieves her symptoms within several minutes. This cold water therapy works by affecting which of the following? A. Vascular tone B. Sinoatrial node automatism C. Atrioventricular node conductivity D. Purkinje fiber conduction E. Ventricular myocardium contractility 5. A 67-year-old man is evaluated for hypertension He complains of occasional morning headaches. His past medical history is also significant for type 2 diabetes mellitus, coronary artery disease, and a stroke with residual left-sided weakness. He underwent coronary artery bypass surgery seven years ago and carotid endarterectomy five years ago. His current medication list includes lisinopril hydrochlorothiazide, amlodipine, metoprolol, aspirin, metformin and glyburide His blood pressure is 190/120 mmHg on the right arm and 170/110 mmHg on the left arm. His heat rate is 65/min Physical examination reveals a periumbilical systolic-diastolic bruit. The latter finding is best explained by which of the following? A. Abdominal aortic aneurysm B. Aortic dissection C. Aortic coarctation D. Renal artery stenosis E. Aorto-enteric fistula 6. A 67-year-old male is brought to the emergency department after a syncopal episode. He lost consciousness while shopping in the mall. He denies any nausea, diaphoresis, chest pain, or shortness of breath. He has had two episodes of lightheadedness over the last month but has not seen a doctor. His past medical history is significant for long-standing hypertension, which is being treated with enalapril. His blood pressure is 135/90 mmHg while supine, and 130/85 mmHg while standing His heat rate is 64/min ECG shows a sinus rhythm with high voltage, prolonged PR interval, prolonged QRS interval, normal QT interval and occasional premature ventricular contractions (PVC) E- chocardiography reveals left ventricular hypertrophy and an ejection fraction (EF) of 55% Which of the following is the most likely cause of this patient's syncope? A. Bradyarrhythmia B. Decreased myocardial contractility C. Torsades de pointes D. Autonomic dysfunction E. Ventricular premature beats 7. A 60-year-old male is 2 days status post primary percutaneous coronary intervention (PCI) with stent placement. He had previously suffered from an antero-lateral myocardial infarction. His cardiac enzymes have been trending down since admission He has recovered well and is ready for discharge He is currently asymptomatic. His temperature is 37.5 C (99.5 F), blood pressure is 130/70 mm Hg, pulse is 66/min, and respirations are 14/min He is discharged with instructions to take the following medications aspirin simvastatin, lisinopril metoprolol and sublingual nitroglycerine. In addition to the medications listed above, which of the following medications should this patient also be taking after discharge? A. Isosorbide mononitrate B. Low molecular weight heparin C. Waffarin D. Clopidogrel E. Amlodipine
