 Part 2 - The Test

 

1) The magnitude of the potassium gradient across the cell membrane:

A) Does not concern the cardiac cells

B) Determines the excitability of nerve and muscle cells

C) Does not have an effect on the serum pH

D) All the above

2) When serum pH falls:

A) Serum potassium rises because potassium shifts from the cells into the vascular space

B) Serum potassium rises because potassium shifts from the vascular space into the cells

C) Serum potassium falls because potassium shifts from the vascular space into the cells

D) None of the above

3) Impairment of renal water excretion may be caused by:

A) Use of thiazide diuretics

B) ECF depletion (e.g., vomiting with continued water intake)

C) Edematous states (e.g., congestive heart failure, cirrhosis with ascites)

D) All the above

4) Hypomagnesemia is treated with:

A) Administration of calcium, which removes magnesium from serum

B) Dialysis

C) 1 to 2 g of IV MgSO4 over 5 to 60 minutes

D) A & B

5) Neurologic symptoms of hypermagnesemia:

A) Muscular weakness and paralysis

B) Ataxia

C) Drowsiness and confusion
D) All the above

6) Hypocalcemia may develop:
A) With toxic shock syndrome
B) With abnormalities in serum magnesium
C) With fluoride poisoning
D) All the above

7) Electrolyte abnormalities:
A) Are among the most common causes of cardiac arrhythmias
B) Can cause or complicate attempted resuscitation and post-resuscitation care
C) A & B
D) None of the above

8) Diagnosis of acute myocardial infarction is based on:
A) Clinical features and presence of risk factors
B) Levels of cardiac biomarker
C) Electrocardiographic changes
D) All the above

9) CK-MB is present in high concentrations in myocardium and:
A) Is present in the lungs and small intestine
B) Is not present in the lungs and small intestine
C) Is not present in the uterus, prostate, and healthy skeletal muscle
D) None of the above

10) In the diagnosis of acute myocardial infarction, especially in patients with other medical conditions such as renal disease or severe musculoskeletal disorders:
A) Measurements of CK and CK-MB have greater sensitivity and specificity than measurements of both cardiac troponins
B) Measurements of both cardiac troponins have greater sensitivity and specificity than measurements of CK and CK-MB
C) Measurements of lactate dehydrogenase have successfully replaced measurements of both troponins
D) None of the above
