1. A licensed practical nurse is caring for a client with chronic
obstructive pulmonary disease who is receiving oxygen at 2 liters per
minute via nasal cannula. Which assessment finding indicates that the
oxygen therapy is effective?
A) Respiratory rate of 26 breaths per minute
B) Oxygen saturation of 92% on pulse oximetry
C) Use of accessory muscles during inspiration
D) Arterial blood gas pH of 7.30
Answer: B) Oxygen saturation of 92% on pulse oximetry
Explanation: The goal of oxygen therapy in COPD is to maintain oxygen
saturation between 88% and 92% to prevent hypoxemia while avoiding
suppression of the hypoxic drive. An oxygen saturation of 92% indicates
adequate oxygenation. A respiratory rate of 26 is elevated, accessory
muscle use suggests respiratory distress, and a pH of 7.30 indicates
acidosis, all of which are signs of ineffective therapy or worsening
respiratory status.

2. A client with heart failure is prescribed furosemide. Which laboratory
value requires immediate notification of the healthcare provider?
A) Serum sodium of 135 mEq/L
B) Serum potassium of 3.0 mEq/L
C) Serum calcium of 9.5 mg/dL
D) Serum magnesium of 2.0 mEq/L
Answer: B) Serum potassium of 3.0 mEq/L
Explanation: Furosemide is a loop diuretic that can cause significant
potassium depletion. A serum potassium of 3.0 mEq/L is below the
normal range of 3.5 to 5.0 mEq/L and places the client at risk for cardiac
arrhythmias. The other values are within normal limits and do not
require immediate action.
3. The LPN is reinforcing teaching for a client prescribed a metered-
dose inhaler. Which instruction is most important to include?
A) "Shake the inhaler vigorously for at least 10 seconds before use."
B) "Hold your breath for 10 seconds after inhaling the medication."
C) "Inhale rapidly and deeply while pressing the canister."
D) "Rinse your mouth with water after using a corticosteroid inhaler."

Answer: D) "Rinse your mouth with water after using a corticosteroid
inhaler."
Explanation: Rinsing the mouth after using a corticosteroid inhaler is
crucial to prevent oral thrush (candidiasis), a common side effect. While
holding the breath for 10 seconds and shaking the inhaler are correct
techniques, the most important instruction to prevent a complication is
mouth rinsing. Inhaling should be slow and deep, not rapid.
4. A client with a nasogastric tube to low intermittent suction has a
gastric output of 800 mL over 8 hours. Which intravenous fluid would
the nurse anticipate being prescribed to maintain electrolyte balance?
A) 0.9% sodium chloride with 20 mEq potassium chloride
B) Dextrose 5% in water
C) 0.45% sodium chloride
D) Lactated Ringer's solution
Answer: A) 0.9% sodium chloride with 20 mEq potassium chloride
Explanation: Large gastric output via NG suction leads to loss of gastric
acids, sodium, and potassium. Isotonic fluids like 0.9% sodium chloride
help restore vascular volume, and potassium replacement is needed due
to losses. D5W and hypotonic fluids do not adequately replace
electrolytes, and lactated Ringer's may not provide sufficient potassium
for these losses.

5. The LPN is caring for a postoperative client who has a Jackson-Pratt
drain. Which finding indicates proper functioning of the drain?
A) The drain is placed below the level of the incision
B) The drainage collection chamber is fully expanded
C) The drain tubing is secured with a safety pin to the bedding
D) The drainage amount has decreased to 10 mL over 24 hours
Answer: A) The drain is placed below the level of the incision
Explanation: For gravity drainage to work effectively, the Jackson-Pratt
drain must be kept below the level of the incision to facilitate fluid flow.
The collection chamber should be compressed, not expanded, to create
suction. Tubing should not be pinned to bedding as it can cause tension
and dislodgement. A decrease in drainage is expected but does not
indicate function.
6. A client is admitted with a diagnosis of acute pancreatitis. Which
laboratory finding is consistent with this condition?
A) Elevated serum amylase and lipase
B) Decreased blood glucose
C) Elevated serum calcium
D) Decreased white blood cell count
