Which site is most appropriate?
A) Deltoid muscle
B) Upper arm
C) Abdomen

holding the dose?
A) Blood pressure 130/80 mmHg
B) Heart rate 58/min
C) Potassium level 4.0 mEq/L
D) Respiratory rate 20/min
Correct Answer: B) Heart rate 58/min
Rationale: Digoxin is held if heart rate is below 60/min to prevent bradycardia.
Normal BP (A), potassium (C), and respiratory rate (D) are not contraindications.
3. A PN is administering an oral medication. Which action verifies the right client?
A) Check the medication label
B) Use two client identifiers
C) Ask the client’s roommate
D) Review the MAR once
Correct Answer: B) Use two client identifiers

6. A PN is caring for a client receiving furosemide. Which electrolyte imbalance is a
risk?
A) Hyperkalemia
B) Hypokalemia
C) Hypernatremia
D) Hypermagnesemia
Correct Answer: B) Hypokalemia
Rationale: Furosemide causes potassium loss, leading to hypokalemia. Hyperkalemia
(A), hypernatremia (C), and hypermagnesemia (D) are not typical.
7. A PN is administering a medication via a nasogastric tube. Which action ensures
safety?
A) Crush enteric-coated tablets
B) Check tube placement
C) Mix medication with formula
D) Flush with 10 mL water
Correct Answer: B) Check tube placement
Rationale: Checking placement prevents aspiration. Crushing (A) is unsafe, mixing
(C) risks interactions, and 15–30 mL (D) is standard for flushing.
8. A PN is reviewing a client’s medication reconciliation. Which action is priority?
A) Administer all ordered medications
B) Verify discrepancies with the provider
C) Skip the client’s home medications

monitored?
A) Hypoglycemia
B) Weight gain
C) Bradycardia
D) Hypotension
Correct Answer: B) Weight gain

A) Use daily to prevent asthma
B) Rinse mouth after use
C) Inhale rapidly
D) Expect drowsiness

reaction?
A) Pain at the site
B) Rash and itching
C) Warmth at the site
D) Clear fluid flow

A) Blood pressure
B) Respiratory rate
C) Temperature
D) Pulse oximetry
Correct Answer: B) Respiratory rate
Rationale: Morphine can depress respirations, making rate the priority. BP (A),
temperature (C), and oximetry (D) are secondary.
13. A PN is teaching a client about metformin. Which instruction is correct?
A) Take with grapefruit juice
B) Monitor for lactic acidosis
C) Expect weight gain
D) Skip doses if fasting
Correct Answer: B) Monitor for lactic acidosis
