Section A: Safe Medication Administration & Advanced Dosage Calculations
Q1. A practical nurse (PN) is preparing to administer medication to an older adult
client. Which physiological change associated with aging must the PN consider
because it significantly increases the risk of drug toxicity?
A) Increased gastric motility and acidity
B) Decreased glomerular filtration rate (GFR) and reduced hepatic blood flow
C) Decreased proportion of body fat
D) Increased serum albumin levels
Answer: B
Explanation: Aging decreases renal function (reduced GFR) and hepatic clearance. This
delays drug metabolism and excretion, allowing medications to accumulate in the
bloodstream and increasing the risk of adverse drug reactions and cumulative toxicity.
Q2. The provider orders 0.25 mg of digoxin PO daily. The pharmacy supplies digoxin
tablets labeled 125 mcg per tablet. How many tablets should the PN administer?
A) 0.5 tablet
,B) 1 tablet
C) 2 tablets
D) 3 tablets
Answer: C
Explanation: First, convert milligrams to micrograms: 0.25 mg = 250 mcg. Next, use the
formula (Desired / Have): 250 mcg / 125 mcg = 2 tablets.
Q3. A client is prescribed an enteric-coated medication. The client states, "I have
trouble swallowing pills. Can you crush this and put it in my applesauce?" What is
the PN's most appropriate response?
A) "Yes, crushing it will help it absorb faster in your stomach."
B) "No, enteric-coated pills must be swallowed whole so they dissolve in the small
intestine rather than irritating your stomach."
C) "I can dissolve it in warm water for you instead of crushing it."
D) "You can chew it quickly before swallowing."
Answer: B
Explanation: Enteric-coated tablets are designed to pass through the stomach intact to
protect the gastric mucosa from irritation or to prevent stomach acid from destroying the
drug. Crushing them destroys this protective barrier, leading to premature release of the
drug and potential gastric distress.
, Q4. The PN is reviewing the prescriptions for a client who is scheduled to start a
high-alert medication. Which action represents a mandatory safety protocol unique to
high-alert medications?
A) Documenting administration at the end of the shift
B) Performing an independent double-check of the medication, dose, and pump
settings with another licensed nurse
C) Asking the client if they feel they need the medication
D) Administering the drug 1 hour before the scheduled time
Answer: B
Explanation: High-alert medications (e.g., insulin, heparin, opioids) carry an increased risk
of causing significant patient harm if misused. Safety organizations mandate an
independent double-check by two licensed nurses to intercept errors before administration.
Q5. A provider writes a prescription that reads: "Furosemide 40mg IVP STAT." How
should the PN interpret the timing of "STAT"?
A) Administer within the next 2 to 3 hours.
B) Administer immediately and exactly once.
C) Give only if the client's blood pressure rises.
D) Administer routinely at the next scheduled medication pass.
Answer: B
