SECTION 1: Fluid and Electrolyte Balance
Question 1
A 72-year-old patient is admitted with confusion and muscle weakness. Laboratory results show serum sodium of 118
mEq/L. The nurse notes the patient has been on a low-sodium diet and taking a thiazide diuretic. Which assessment
finding is most consistent with this electrolyte imbalance?
A. Decreased deep tendon reflexes and orthostatic hypotension
B. Hyperactive bowel sounds and increased thirst
C. Bounding pulses and elevated blood pressure
D. Dry mucous membranes and poor skin turgor only
Correct Answer: A
Rationale:
Hyponatremia commonly produces neurological changes, muscle weakness, and decreased reflexes; orthostatic hypotension can
accompany fluid shifts. Hyperactive bowel sounds are more typical of hyperkalemia or hypermagnesemia, while bounding pulses
suggest fluid volume excess.
Question 2
A patient with heart failure is receiving furosemide. The nurse reviews the morning laboratory results and notes a
potassium level of 2.9 mEq/L. Which clinical manifestation should the nurse monitor for most closely?
A. Cardiac dysrhythmias and muscle cramps
B. Hyperactive deep tendon reflexes and diarrhea
C. Increased blood pressure and bounding pulses
D. Flushed skin and bradycardia
Correct Answer: A
Rationale:
Hypokalemia increases the risk of ventricular dysrhythmias and causes muscle weakness or cramps. Hyperactive reflexes and diarrhea
are associated with hyperkalemia; flushed skin and bradycardia are more typical of hypermagnesemia.
Question 3
A patient is receiving intravenous 0.9% sodium chloride at 125 mL/hr. After four hours the nurse notes crackles at the
lung bases, a weight gain of 1.2 kg, and jugular venous distention. Which action is the priority?
A. Slow the infusion rate and notify the provider of possible fluid volume excess
B. Continue the current rate and reassess lung sounds in two hours
C. Increase the rate to complete the ordered volume more quickly
D. Discontinue the intravenous access and encourage oral fluids
Correct Answer: A
Rationale:
Crackles, rapid weight gain, and jugular venous distention indicate fluid volume excess. Slowing the infusion and notifying the provider
are appropriate first actions. Continuing or increasing the rate would worsen overload.
Question 4
A patient with chronic kidney disease has a serum calcium of 7.2 mg/dL and an elevated phosphorus level. Which
assessment finding is most expected?
A. Positive Trousseau and Chvostek signs
B. Decreased deep tendon reflexes and lethargy
C. Polyuria and polydipsia
D. Warm, flushed skin and bradycardia
Correct Answer: A
Rationale:
Hypocalcemia produces neuromuscular irritability manifested by Trousseau and Chvostek signs. Decreased reflexes and lethargy are
more consistent with hypercalcemia or hypermagnesemia.
