BIOL 235 Human Anatomy and Physiology Assignment 3 Questions and correct Answers (Correctly Explained). 1. Some patients who suffer from hypertension (high blood pressure) are prescribed medications that are in the category of angiotensin-converting enzyme (ACE) inhibitors. Explain why these drugs are used to combat hypertension. When blood volume falls or blood flow to the kidneys decreases, juxtaglomerular cells in the kidneys secrete renin into the bloodstream. In sequence, renin and ang...

In addition to providing continuous high-quality CPR, what is the other priority intervention for this patient? - Administering epinephrine as early as possible 2. A patient has experienced return of spontaneous circulation (ROSC) after cardiac arrest.

AWHONN Intermediate Fetal Monitoring Exam Questions And Answers If fetal arterial pressure begins to fall below normal levels: - ANS A. BARORECEPTORS CAUSE VASOCONSTRICTION AND INCREASE THE FHR An increase in arterial blood pressure produces vessel distension and causes arterial baroreceptors to send neuronal messages to the cardioinhibitory center, which in turn causes rapid slowing of the fetal heart rate via the parasympathetic vagus nerve. A decrease in arterial pressure results in ...

• A 38-week primigravida who works as a secretary and sits at a computer for 8 hours each day tells the nurse that her feet have begun to swell. Which instruction would be most effective in preventing pooling of blood in the lower extremities? Move about every hour Pooling of blood in the lower extremities results from the enlarged uterus exerting pressure on the pelvic veins. Moving about every hour will straighten out the pelvic veins and increase venous return. • A 26-year-old, g...
