Question

A room has a normal total air pressure, and oxygen levels, but has 10 times the normal percentage of carbon dioxide. Which of the following are true?

		At least one of the other gases has a lower partial pressure
		Your breathing will speed up in this room
		Your blood pH will increase in this room
		The oxygen saturation of a person in this room will be lower QUESTION 15 A patient is experiencing polyuria. Which of the following could be responsible? Excess of albumin in the blood Impaired myogenic feedback mechanisms ACE inhibitors Thiazide diu A patient has experienced a drastic rise in blood osmolarity (concentration). Which issues could cause this? Use of an osmotic diuretic Dehydration Low efficiency renin enzymes Excess release of ADH Which responses are equally effective regardless of whether a patient has encountered a given pathogen before? Phagocytosis Cell-mediated immunity Inflammation Humoral immunity

Answer 1

14) B) Your breathing will speed up in this room

Explanation: Inhalation of air rich in carbon dioxide increases the partial pressure of CO2 in the arterial blood which stimulate the respiratory center to increase rate and depth of the respiration in order to wash out the excessive CO2.

15) Thiazide diuretics

Explanation: Thiazide diuretics is responsible for inhibiting reabsorption of sodium (Na+) and chloride (Cl−) ions from the distal convoluted tubules in the kidneys by blocking the thiazide-sensitive Na+-Cl− symporter. This results in loss of Na+ and water from the urine leading to polyuria.

16) Dehydration

Explanation: dehydration results in loss of water from the body without the loss of solute leading to drastic increase in plasma osmolarity.

I17) Inflammation

Explanation: It is the part of innate immunity which occurs equally effective regardless of type of pathogen or the previous encounter
