NPTE Test Questions Practice questions with correct answers

What conditions are the abnormal heart sounds S3 and S4 associated with, respectively? A. S3 = MI or HTN; S4 =CHF B. S3 = Tracheal Stenosis; S4 = Asthma C. S3 = closure of Mitral and Tricuspid Valves; S4 = Closure of Pulmonary Valves D. S3 = CHF; S4 =MI or HTN - Answer Feedback Correct Answer - D S3 is heard in early diastole (after S2) and is associated with CHF. S4 is heard in late diastole (before S1) and is associated with an MI or hypertension. A chronic smoker diagnosed with COPD was tested for an arterial blood gas (ABG) analysis. After reviewing the patient's chart, the physical therapist is MOST likely to see which of the following changes in the ABG results? A. Decreased PaCO2, increased PaO2, and decreased pH. B. Decreased PaCO2, decreased PaO2, and increased pH. C. Increased PaCO2, increased PaO2, and increased pH. D. Increased PaCO2, decreased PaO2, and decreased pH - Answer Feedback Correct Answer - D COPD causes dilation and destruction of the airspaces and alteration in pulmonary vasculature resulting in mismatch in ventilation in the alveoli and perfusion in the capillary membrane. This results in hypoxemia (decreased oxygen in the arterial blood) in the early stage of COPD and hypercapnea (increased carbon dioxide in the arterial blood) as the disease progresses.
