What FEV1/FVC ratio on spirometry is consistent with airflow obstruction? - 70% What is used to characterize the degree of obstruction? - the degree of reduction in FEV1 What is considered moderately reduced FEV1? - 50-80% What is considered severely reduced FEV1? - 34-49% What is considered very severely reduced FEV1? - less than 34% In patients with obstruction, what additional test on spirometry should be performed? - bronchodilator challenge (2-4 puffs of a short acting B2 ago...

Cardiac enzyme/marker interpretation (troponin, CK-MB, BNP) Troponin: Troponin is a protein in heart muscle cells that regulates muscular contraction. When the heart muscle is damaged, as in a heart attack, troponin is released into the bloodstream. Troponin levels can become elevated 3-4 hours after a heart attack and can remain elevated for up to 14 days. Therefore, it is a highly specific indicator of heart damage. CK-MB (Creatine Kinase-MB): CK-MB is a form of creatine kinase found mostl...

What is the difference between an anaphylactic and anaphylactoid reaction? - Anaphylactoid reaction is clinically indistinguishable from anaphylactic reaction but does not require previous exposure to the antigen. Anaphylactoid reaction is not IgE mediated, and direct activation and degranulation of mast cells are thought to be triggered by the complement system. Anaphylactic reaction requires previous exposure to the antigen and is IgE mediated What happens to SvO2 if oxygen delivery decre...

Pathophysiology NU 545-- Unit 5-- Pulmonary/ Kidney I Rated A+ Alveolar Type 1 cells Alveolar Type 2 cells Surfactant Cells which provides structure for alveoli. Cells of the alveoli which secrete surfactant. A lipoprotein that coats the inner surface of the alveolus and facilitates its expansion during inspiration. Lowers alveolar surface tension at end expiration and prevents lung collapse. Contributes to control of lung inflammation and innate and adaptive immunity. Su...

PCCN Cardiac Exam 127 Questions with Verified Answers Which of the following is the outermost lining of the heart? A. Endocardium B. Myocardium C. Transcardium D. Pericardium - CORRECT ANSWER D. Pericardium "Endo" meaning "within" is associated with the innermost lining of the heart, so eliminate A. The myocardium is associated with the heart's middle layer, so eliminate option B. The "transcardium" is somewhat of a contrived term, so eliminate C as well. The prefix in pericardium...

The majority of right atrial filling occurs during what phase of respiration? inspiration *inspiration drops the pressure in the chest allowing an increase from the vena cava into the RA Which heart sound marks the start of systole? S1 *S1 represents the atrioventricular valves closing and the start of the QRS wave on the EKG On an EKG, when does ventricular diastole take place? Ventricular and diastole occurs from the end of the T wave to the onset of the QRS wave Right dominant coronar...
