ADVANCED FLUID AND ELECTROLYTE
DISORDERS: HIGH-LEVEL NCLEX-STYLE
QUESTIONS WITH CORRECT ANSWERS AND
RATIONALES (2025–2026)
congestive heart failure
due to inefficient pumping of excessive fluids -
CORRECT ANSWERS-Which medical diagnosis
would cause the nurse to include nursing
interventions appropriate for hyponatremia in the
plan of care?
tumor lysis syndrome
causes movement of potassium from the intracellular
fluid (ICF) to the extracellular fluid (ECF) -
CORRECT ANSWERS-Which syndrome would the
, nurse suspect when a patient has a potassium level
of 6.2 mEq/dL?
Loop Diuretics
contraindicated during episodes of hypokalemia
because these medications cause the kidneys to
excrete sodium and potassium. Thus administration
of this type of medication at this time would worsen
the hypokalemia, putting the patient at risk for
dysrhythmias. The prescribing health care provider
should be consulted for potassium replacement
therapy, and the drug should be withheld until the
potassium has returned to normal range. -
CORRECT ANSWERS-The morning laboratory
results of a patient admitted with heart failure reveal
a serum potassium level of 2.9 mEq/L.
Which classification of medications would be
withheld until consulting with the health care
provider?
4.5 mEq/L
The normal range for serum potassium is 3.5 to 5
mEq/L - CORRECT ANSWERS-The patient
presents with a one-time prescription for potassium
chloride 20 mEq in 250 mL of normal saline IV, to be
given immediately.
