UPDATE 2026/2027
Serum sodium levels below 120 mEq/L are often
associated with:
A. seizure activity
B. diminished or changes in the LOC
C. syndrome of inappropriate diuretic hormone (SIADH)
D. all of the above
❖D. all of the above
When serum sodium levels are this low, the patient may
become very symptomatic. seizure activit, diminished or
changed LOC and behavioral changes may be related to
SIADH (water intoxication associated with lowered sodium
levels)
,Page 2 of 100
The following drug/s may be administered to remove
extra potassium from the body in the patient with
hyperkalemia secondary to AKI?
A. sodium bicarbonate
B. calcium chloride
C. glucose and insulin infusion
D. kayexalate and sorbitol
❖D. kayexalate and sorbitol
These drugs increase gastric motility (cause diarrhea).
Potassium is then evacuated from the body.
,Page 3 of 100
Sodium bicarbonate, glucose and insulin shift the
potassium from the intravascular compartment into the
body's cells and do not remove the potassium from the
body.
The electrolyte abnormality that produces a U wave and a
depressed ST-segment on the ECG and ventricular
irritability is:
A. hypernatremia
B. hyperkalemia
C. hypokalemia
D. hypocalcemia
❖C. hypokalemia
low potassium causes a ventricular irritability (VT and VF)
and causes prominent U wave formation as well as ST-
segment depression
, Page 4 of 100
Which ECG finding would NOT be observed in the
presence of hyperkalemia?
A. prolonged PR interval
B. absence of P waves
C. ventricular irritability
D. widened QRS complexes
❖C. ventriculare irritability
hyperkalemia is a ventricular depressant causing
bradycardias, widened QRS, absence of P waves, and
heart blocks. ventricular irritability is from hypokalemia
Which of the following elements is not filtered during
glomerular filtration?
A. sodium
B. potassium
C. proteins
D. creatinine
