Why does anaphylactic shock cause severe hypoxia very quickly?1) Generalized vasoconstriction reduces venous return.2) Bronchoconstriction and bronchial edema reduce airflow.3) Heart rate and contractility are reduced.4) Metabolic rate is greatly increased. - CORRECT ANSWER - 2) Bronchoconstriction and bronchial edema reduce airflow.
A cardiac pacemaker would most likely be inserted in cases of:
1) angina pectoris.2) heart block.3) congestive heart failure.4) ventricular fibrillation. - CORRECT ANSWER -2) heart block.

The most common factor predisposing to the development of
varicose veins is:
1) trauma.2) congenital valve defect in the abdominal veins.3) infection.4) increased venous pressure. - CORRECT ANSWER -4) increased venous pressure.
In the period immediately following a myocardial infarction, the manifestations of pallor and diaphoresis, rapid pulse, and
anxiety result from:
1) onset of circulatory shock.2) the inflammatory response.3) release of enzymes from necrotic tissue.4) heart failure. - CORRECT ANSWER -1) onset of circulatory shock.
Septic shock differs from hypovolemic shock in that it is
frequently manifested by:
1) fever and flushed face.2) elevated blood pressure.3) increased urinary output. 2 / 4

4) slow bounding pulse. - CORRECT ANSWER -1) fever and flushed face.
SEPTIC SHOCK = WARM SHOCK
hypovolemic = vasoconstriction due to reduced volume and flow
In patients with congestive heart failure, ACE inhibitor drugs are
useful because they:
1) reduce renin and aldosterone secretion.2) slow the heart rate.3) strengthen myocardial contraction.4) block arrhythmias. - CORRECT ANSWER -1) reduce renin and aldosterone secretion.
Excessive fluid in the pericardial space causes:
1) increased cardiac output.2) myocardial infarction.3) reduced venous return.4) friction rub. - CORRECT ANSWER -3) reduced venous return.

Friction rub is less fluid, fluid constricting heart so low CO
The endothelial cells of the vasculature have a(n) ______ action and conrol the nearby smooth muscle cells and local environs.1) endocrine 2) paracrine 3) autocrine 4) coagulative - CORRECT ANSWER -2) paracrine
autocrine - controls itself paracrine - controls things around it
Match the endocrine/paracrine molecule to its usual action in most parts of the body parasympathetic action endothelin angiotensin II nitric oxide epinephrine 1.most active vasoconstrictor released from vessel-lining cells 2.a vasoconstrictor released from adrenal cells
