What is the most likely cause of this occurance after ruling out hypoxia? A) Congetital heart defect B) DIaphramatic hernia C) Fluid overload D) Hypothermiaa. Name the common electrolytes lost because ofdiarrhea.b. State the major effect on the body of sodiumloss and potassium loss.c. State and explain what arterial blood gas levelsmay be expected in the presence of severevomiting.

A) Antipsychotics B) Beta blockers C) Antiepileptics D) None of the above Why would a cardiac glycoside be indicated in congestive heart failure? A) Increased ventricular strength B) Increased glycolysis C) Increased urination D) VasoconstrictionAldosterone secretion is regulated by: A. renin secretion by the kidney resulting in the formation of angiotensin II that directly causes aldosterone release B. direct humoral stimulation of adrenal cortex cells by potassium ions C. ACTH during conditions of severe stress D. Atrial natriuretic pepside causing inhibition of aldosterone effects E. All of these are correctDiabetes insipidus:* a. Hypernatremia due to decreased water intake b. Hypernatremia due to excess water loss c. Hyponatremia due to increased sodium loss d. Hyponatremia due to increased water retention
- explain how/why diuretics that block ADH secretion would work to reduce blood pressure (ie, what ASPECT of blood pressure is affected, and how is it affected)A patient is found to have severe arteriosclerosis of the renal arteries,which has reduced renal blood pressure. Which of these is consistentwith that condition?a. hypotensionb. hypertensionc. decreased vasomotor toned. exaggerated sympathetic stimulation of the hearte. Both a and c are correct.Although orthostatic hypotension has many causes, in the elderlyit can be due to age-related decreases in neural and cardiovascular responses. Decreased fluid intake while feeling ill and sweating due to a fever can result in dehydration. Dehydration candecrease blood volume and lower blood pressure, increasing thelikelihood of orthostatic hypotension.a. Describe the normal response to a decrease in blood pressureon standing.b.
