⩥ Besides sodium, aldosterone also regulates which electrolyte?
A) Chloride
,B) Potassium

⩥ The humoral immune response consists of molecules produced by T
cells. True or False. Answer: False (B cells)
⩥ Hypokalemia is characterized by:
a) slow repolarization and a spiked T-wave
b) slow repolarization and a shallow T-wave
c) rapid repolarization and a spiked T-wave
d) rapid repolarization and a shallow T-wave. Answer: B (slow
repolarization and shallow T-wave)
⩥ Which of the following is NOT true of Natural Killer Cells?
a) they recognize and eliminate cells infected with viruses
b) they produce cytokines and toxic molecules
c) they are a vital component of the adaptive immune system
d) forcing apoptosis, or cell suicide, of infected cell is one way NK cells
operate. Answer: C (they are a vital component of the adaptive immune
system)
,⩥ What electrolyte should be closely monitored during insulin
administration to an insulin dependent diabetic patient?
potassium
Sodium
Chloride
Magnesium. Answer: Potassium
⩥ An invading antigen would stay away from all of the following
except:
Red blood cells
Immunoglobulins
Neutrophils. Answer: Red Blood Cells
⩥ True or False: Starling Forces also known as net filtration is composed
of 4 components, Capillary hydrostatic pressure, blood pressure,
interstitial hydrostatic pressure, and interstitial oncotic pressure..
Answer: FALSE, blood pressure is considered capillary hydrostatic
pressure the real answer would include capillary oncotic pressure where
blood pressure is placed in the statement.
⩥ In severe hyperkalemia:
a. Causes acute, chronic renal failure
b. Causes hyperparathyroidism
, c. Causes cerebral edema and increased intracranial pressure
d. Causes muscle weakness, loss of muscle tone and paralysis. Answer:
D. causes muscle weakness, loss of muscle tone and paralysis
Acute, chronic renal failure is results of hyperphosphatemia
Hyperparathyroidism is result of hypercalcemia
Cerebral Edema, and increased ICP result of hyponatremia

for Hydrogen ions.
A.) protein
B.) potassium
C.) Keloids
D.) Chemotactic factors. Answer: B. Potassium
⩥ This will activate the plasma protein system bringing about damage to
bacteria or more recognition by macrophages.
A.) Normal microbiome
B.) Mannose-binding lectin (MBL)
C.) opportunistic microorganisms
D.) chemotactic factors. Answer: B. Mannose-binding Lectin (MBL)
