FSCJ NUR 1023C EXAM 3 LATEST VERSION
WITH 300 QUESTIONS AND CORRECT DETAILED
SOLUTIONS JUST RELEASED THIS YEAR
Question 1: A nurse is caring for a patient with a nasogastric tube that has been on continuous
suction for several days. Which electrolyte imbalance is the patient most at risk for developing?
A) Hypernatremia
B) Hyperkalemia
C) Hypokalemia
D) Hypermagnesemia
Answer: C – Gastric suction removes fluid rich in hydrochloric acid and potassium, placing the
patient at high risk for hypokalemia.
Question 2: A patient presents with confusion, muscle cramps, and a serum sodium level of 128
mEq/L. Which intervention would the nurse expect the physician to order?
A) Administer 3% normal saline IV cautiously
B) Restrict oral fluid intake

C) Encourage a high-sodium diet
D) Administer loop diuretics
Answer: A – This patient has severe symptomatic hyponatremia (below 130 mEq/L); hypertonic
saline (3%) is indicated to correct the deficit carefully.
Question 3: The nurse is teaching a patient about foods high in potassium. Which meal
selection indicates the patient understands the teaching?
A) Grilled chicken breast with apple sauce
B) A baked potato with steamed spinach and a banana
C) A turkey sandwich on white bread with diet soda
D) A salad with lettuce, cucumber, and low-fat yogurt
Answer: B – Potassium is abundant in fruits (bananas) and vegetables (potatoes, spinach); this
meal contains the highest potassium sources.
Question 4: A patient with chronic kidney disease has a serum potassium level of 6.5 mEq/L.
Which assessment finding should the nurse prioritize?

A) Severe muscle weakness and cardiac arrhythmias
B) Numbness and tingling of the extremities
C) Decreased deep tendon reflexes
D) Hyperactive bowel sounds
Answer: A – A potassium of 6.5 mEq/L indicates severe hyperkalemia; the most life-threatening
complications are cardiac arrhythmias and muscle weakness/paralysis.
Question 5: A client is taking furosemide (a potassium-wasting diuretic). The nurse should
monitor for which electrolyte imbalance?
A) Hyperkalemia
B) Hypercalcemia
C) Hypokalemia
D) Hyponatremia
Answer: C – Loop and thiazide diuretics increase potassium excretion by the kidneys, leading to
hypokalemia unless supplemented.

Question 6: When administering intravenous potassium chloride (KCl), which nursing
intervention is the highest priority?
A) Administer as a rapid IV push to relieve symptoms quickly
B) Monitor the IV site for phlebitis only
C) Ensure the medication is diluted and administered via an infusion pump
D) Hold the patient's oral potassium supplements
Answer: C – IV potassium MUST be diluted and administered via infusion pump (never IV push)
to prevent fatal cardiac arrhythmias.
Question 7: What is the normal serum sodium level for an adult?
A) 125-135 mEq/L
B) 135-145 mEq/L
C) 145-155 mEq/L
D) 115-125 mEq/L
Answer: B – Normal sodium range is 135-145 mEq/L; levels below or above this require nursing
intervention.
