A healthy heart is compliant. What does that mean? - CORRECT ANSWER: Compliant
hearts stretch easily, and therefore fill with blood easily during diastole.
A meal that is high in salt will cause temporary edema. Why? - CORRECT ANSWER:
Absorption of NaCl at the GI tract results in increased water absorption as well. If the
NaCl increases plasma osmolarity then ADH is released which stimulates water
reabsorption by the kidney. This fluid expands the extracellular volume resulting in
edema.
A patient arrives at your clinic with a rapid respiratory rate, plasma pH of 7.30, and a
PCO2 of 40 mmHg. - CORRECT ANSWER: This is a metabolic acidosis because pH is
low and PCO2 is normal.
A person with type O blood - CORRECT ANSWER: Can accept type O blood only
because they have anti-A and Anti-B antibodies in their plasma.
A transfusion of serum would differ from a transfusion of saline in that - CORRECT
ANSWER: Oncotic pressure doesn't change with serum but oncotic pressure will drop
with a saline transfusion.
About 2/3 of the blood entering the liver comes from the hepatic portal circulation. What
is the correct pathway for blood flow? - CORRECT ANSWER: hepatic portal vein
→capillary sinusiods→hepatic vein→inferior vena cava
Anaphylaxis - CORRECT ANSWER: has symptoms such as hives, welts, and airway
constriction resulting from excessive immune response that is mediated by histamines.
, Angiotensin II produces a coordinated elevation in the ECF volume by - CORRECT
ANSWER: 1. triggering the production and secretion of aldosterone
2. causing the release of ADH
3. stimulating thirst
Arteries carry oxygenated blood. True or False? - CORRECT ANSWER: False. Arteries
carry blood AWAY from the heart and veins carry blood returning to the heart. Systemic
arteries carry oxygenated blood and pulmonary arteries carry deoxygenated blood.
Blood flow in the kidney flows through a portal circulation. Which of the following
statements correctly describes the portal circulation in the kidney? - CORRECT
ANSWER: Afferent arteriole-- Glomerular capillaries -- efferent arteriole---peritubular
capillaries
Blood pressure in the femoral artery is higher compared to the brachial artery, but it is
further away from the heart. What explains this? - CORRECT ANSWER: Two factors,
length and vessel radius, influence peripheral resistance. Radius is more important. The
femoral artery has a larger radius compared to the brachial, and therefore pressure
doesn't drop as much
Bronchial smooth muscle - CORRECT ANSWER: Contracts during increased
parasympathetic activity, lowering airflow due to increased resistance.
Bruising is usually associated with swelling. Why? - CORRECT ANSWER: Blood loss
from capillaries results in some plasma proteins moving to the interstitial space. These
proteins, which are usually on inside the capillary, reduce reabsorption.
Calculate the amount of K+ in plasma. Assume that the hematocrit is 50 and that there
are 5 L of blood in your patient. The MW of K+ is 35 g/mol. - CORRECT ANSWER: 12.5
mmol
Choose the correct description for filtration, reabsorption, or secretion by the kidney. -
CORRECT ANSWER: Secretion refers to movement from peritubular fluid into the
nephron.
