Which of the following disorders can lead to a low V/Q mismatch?
A. Pulmonary edema
B. Pulmonary Embolism
C. Pulmonary Hypertension
D. Hypercapnia - Answer A. Pulmonary edema
Nitric oxide, which is released by the glomerular endothelial cells, causes which physiological process to
occur?
A. Vasoconstriction
B. Vasodilation - Answer B. Vasodilation
What would be a normal physiological response in regard to osmosis be in a patient with hyperglycemia?
- Answer The patient's serum is hypertonic and the fluid will move out of the cell
How does the parasympathetic nervous system decrease heart rate? - Answer Release of ACH from the
parasympathetic system increases the permeability of K+ ions and leads to hyperpolarization of the cell.
A patient is in renal failure. The patient reports a history of severe diarrhea for several days. They also
report they have not been able to eat or drink anything for the last 24 hours due to not feeling well. The
NP would suspect that this patient's renal failure is a (pre/intral/post renal) and is due to
(dehydration/ischemia/urinary obstruction). - Answer Prerenal; dehydration
Which of the following cardiac alterations could lead to left sided hypertrophic cardiomyopathy?
A. Aortic stenosis
B. Pulmonary hypertension
C. Cardiac dilation
D. Amyloidosis - Answer A. Aortic stenosis

heart failure
If a patient's BP was 200/120 what would you expect to occur physiologically in the kidneys? - Answer
Afferent arteriole constriction
GFR is directly related to.. - Answer renal blood flow and perfusion pressure in the glomerular
capillaries
Which of the following represents ventricular systole on the ECG?
A. PR interval
B. QRS
C. ST interval
D. QT interval - Answer QT interval

means there is a large presence of - Answer Protein
When reviewing the patients chart a provider reads that there is nephritic sediment in the urine. This
means there is a large presence of - Answer Blood
What are two functions of surfactant in the lungs? - Answer -Keeps alveoli open and free of fluid
