A) An adult with exercise induced bronchospasm B) An adult with a suspected shunt C) An adolescent with myasthenia gravis D) An obese child correct answers B

PHYS 506 Anatomy and Physiology Respiratory MCQs Answers Lung Compartments 1. A spirometer can be used to directly measure which of the following? (A) Functional residual capacity (B) Peak flow rate (C) Residual volume (D) Total lung capacity (E) Vital capacity Answer: E. A spirometer is an instrument that records the volume of air moved into and out of the lungs during breathing, and therefore can only be used to measure lung volumes and capacities that can be exchanged with the envi...

What is a normal FEV1 in a normal healthy adult? This is an exact statistical percentage value. correct answer: - 83% What shape of the flow-volume loop is typical for the patient with a fixed upper airway obstruction? correct answer: -Box shaped Which volumes or capacities cannot be measured by simple Spirometry? correct answer: (FRC, TLC, RV) Exam FRC and RV When an SVC is significantly larger than a FVC, what does this indicate? correct answer: An Obstruction is present What i...

Florida University: Chapter 20-31| NUR 3125Med-Surg Exam 3 Chapter 20: Assessment of Respiratory Function Purpose of the respiratory system ● Deliver oxygen to the body, expels carbon dioxide from the body ○ Works with the circulatory system ● Upper respiratory system: warms and fills air ○ Nose: serves as passageway, filters impurities, humidifies and warms air ○ Sinuses and nasal passages ■ Paranasal sinuses: lines with mucosa and ciliated pseudostratified epithelium; s...

Interstitial lung disease (ILD) correct answers - Is a restrictive disease that causes lung volumes to decrease - primary pathologic change are Alveolar-capillary membrane structures replaced by fibrotic tissue - Causes increased mPAP & CVP - Cause pleural friction rub and cor pulmonale - consist of dull percussion notes - Cough and dyspnea are the two most common symptoms - The term refers to a broad group of inflammatory lung disorders characterized by fibrotic infiltrates in the lower...

FEV1/FVC <0.7 - indicates airflow obstruction on spirometry >/=10% increase from baseline in FEV1, FVC, or both with bronchodilator therapy - indicates reversible airway obstruction on spirometry restrictive lung dz - equal reductions in FEV1 and FVC suggests obstructive: normal or increased restrictive: decreased - differentiate TLC in restrictive vs obstructive disease DLCO - evaluates gas transport across the alveolar-capillary membrane DPLD - decreased DLCO and reduced ...
