Fluid and Electrolyte NCLEX 2026 Realistic Questions And
Answers With 100% Verified Solutions| Achieving Sore Of A+.
The nurse is caring for a client with heart failure. On Assessment, the nurse notes
that the client is dyspneic and crackles are audible on auscultation. What additional
signs would the nurse expect to note in this client if excess fluid volume is present?
1 - weight loss
2 - Flat neck and head veins
3 - An increase in BP
4 - Decreased central venous pressure - ANSWER: 3 - Increase in BP
Reason:
-Dyspneic - difficulty breathing and crackles are findings of fluid volume excess
(overhydration)
-The other symptoms would not match because they should be the opposite (weight
gain, distended veins, elevated CVP)
The nurse is preparing to care for a client with a potassium deficit. The nurse
reviews the client record and determines that the client was at risk for developing
the potassium deficit because of which situation?
1 - Sustained tissue damage
2 - Requires nasogastric suction
3 - Has a history of Addison's disease
4 - Is taking potassium-retaining diuretics - ANSWER: 2 - Required nasogastric
suction
Reason:
- Hyopkalemia - potassium deficit (normal levels 3.5 mEq/L - 5.0 mEq/L)
, - The other points are risks for HYPERkalemia
The nurse reviews a client's electrolyte laboratory report and notes that the
potassium level is 2.5 mEq/L. Which pattern would the nurse note on the electrolyte
cardiogram as a result of the lab value?
1 - U waves
2 - Absent P waves
3 - Elevated T waves
4 - Elevated ST segment - ANSWER: 1 - U waves
Reason:
- Level is below normal limit (HYPO)
- This results in the following ECG results: ST depression, shallow/flat/inverted T
wave, prominent U wave
The nursing student needs to administer potassium chloride IV as prescribed to
client with hypokalemia. The instructor determines that the student is unprepared if
the student states that which action is part of the plan for preparation and
administration of the potassium?
1 - obtaining IV infusion pump
2 - Monitoring urine output during administration
3 - Preparing the medication for bolus administration
4 - Ensuring the med is diluted in the appropriate amount of normal saline -
ANSWER: 3 - Preparing for bolus administration
Reason:
- Bolus = IV push
