Questions With Solutions
As shock progresses, the postcapillary sphincters fail due to acidosis and hypoxia, allowing
microscopic blood clots and lactic acid to re-enter the bloodstream; this phase is called:
A.
extensive cell death.
B.
compensation.
C.
the stagnant phase.
D.
the washout phase. Correct Ans - D. the washout phase.
The sodium/potassium pump will fail to operate, potentially precipitating the death of the
cell, during which of the following conditions?
A.
Anaerobic metabolism
This is the correct answer.
B.
Oxygen exchange
C.
Hemoglobin saturation
D.
Aerobic metabolism Correct Ans - A.
Anaerobic metabolism
You respond to the scene of an 82-year-old female who received a severe laceration when a
glass she was washing broke. Your patient appears to have lost a significant amount of
blood, has cool clammy skin, and a blood pressure of 92/72 mmHg. Her pulse rate is 78
beats per minute and respirations are 20 breaths per minute with a good tidal volume. You
feel she is going into shock. Why is her pulse rate low for her condition?
A.
She has no cellular hypoxia.
B.
Her skin must be cool for another reason.
C.
She is exhibiting signs of a significant compensatory mechanism.
D.
She may be exhibiting a decreased sympathetic nervous system response. Correct Ans
- D.
She may be exhibiting a decreased sympathetic nervous system response.
, The failure of the sodium/potassium pump in a cell results in cell death. The death of the
cell can trigger death in surrounding cells in a process called:
A.
anaerobic metabolism.
B.
lactic acidosis.
C.
osmosis.
D.
apoptosis. Correct Ans - D.
apoptosis.
For a person weighing 70 kg, if breathing becomes shallow and the tidal volume decreases
to ________ mL, only 150 mL is available for gas exchange.
A.
450
B.
500
C.
300
D.
350 Correct Ans - C.
300
If left untreated, hypoglycemia will eventually progress to:
A.
pancreatitis.
B.
hepatomegaly.
C.
seizures and coma.
D.
endocarditis. Correct Ans - C.
seizures and coma.
Which of the following statements regarding defibrillation during cardiac arrest is
ACCURATE?
A.
The only rhythm that can be defibrillated is ventricular fibrillation.
B.
Restoring circulation through CPR is effective to defibrillate the patient.
C.
Asystole can be converted to a normal sinus rhythm.
D.
The cells require uniform depolarization so they can repolarize together. Correct Ans -
D.
