NPTE Test Practice Questions And Answers (Verified Solution) With Rationale

NPTE Test Practice Questions And Answers (Verified Solution) With Rationale 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 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 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. A geriatric patient recently developed CHF. The patient has symptoms of nausea, vomiting, and gastrointestinal irritability. The patient also presents with mental confusion and frustration. Based on these symptoms, what clinical condition does the therapist suspect? A. Alzheimer's disease B. Dementia C. Digoxin toxicity D. Age related symptoms Feedback Correct Answer - C Signs of digoxin toxicity in patients with CHF : Nausea, vomiting, headache, dizziness, confusion, abdominal pain, delirium, vision disturbance. With Alzheimer's and dementia, patient will experience significant memory loss. A patient has a history of diabetes, hypertension, and chronic heart failure. The patient's venous filling time is 10 seconds, while Homan's sign and rubor dependency tests are both negative. These findings support which of the following diagnoses? Select one: A. Chronic venous insufficiency B. Intermittent claudication C. Arterial insufficiency D. Lymphedema Feedback Correct Answer - A Venous filling time- The extremity is elevated and then lowered into a dependent position. The time it takes for the veins on top of the foot to refill is recorded. Normal filling time is 15 seconds. Greater than 15 seconds indicates arterial disease whereas less than 15 indicate venous disease. Rubor dependency test is negative indicating no arterial insufficiency. No signs of intermittent claudication and lymphedema are seen. While evaluating a 30-year-old male with shoulder pain, the therapist applies pressure at the end range of shoulder abduction and external rotation. The patient feels a sudden PARALYZING pain and WEAKNESS in his shoulder. This finding is MOST LIKELY an indication of: A. Thoracic outlet syndrome B. Myotome involvement C. Anterior instability D. Cervical spondylosis Feedback Correct Answer - C The therapist is performing anterior apprehension test or crank test. This test is primarily designed to check for traumatic instability problems causing gross or anatomical instability of the shoulder; positive anterior apprehension test indicates anterior instability. A physical therapist is examining a patient with hypomobile talocrural joint and finds that the range of motion of ankle dorsiflexion is limited. Which of the following mobilization techniques can be used to increase ankle dorsiflexion? A. Posterior glide of talus with small amplitude oscillations into tissue resistance at the limit of available joint motion B. Anterior glide of talus with small-amplitude rhythmic oscillations performed at the beginning of the range C. Posterior glide of talus with small-amplitude rhythmic oscillations performed at the beginning of the range D. Anterior glide of talus with small amplitude oscillations into tissue resistance at the limit of available joint motion Feedback Correct Answer - A Posterior glide of talus with small amplitude oscillations into tissue resistance at the limit of available joint motion At the talocrural joint, convex talus moves over with the concave mortise made up of the tibia and fibula. So, according to convex-concave rule, posterior glide of talus can be used to increase ankle dorsiflexion. Grade I, i.e. small-amplitude rhythmic oscillations performed at the beginning of the range is primarily used for treating joints limited by pain or muscle guarding. Grade IV, i.e. small-amplitude rhythmic oscillations performed at the limit of the available motion and stressed into the tissue resistance is used as stretching maneuver to increase range of motion. So, grade
