ATI RN Pharmacology 2025/2026 Proctored Exam 250 Verified Q&A & NGN
Rationale Pack
This ultimate 250-question mega-bank is designed for the ATI RN Pharmacology Proctored
Exam (2023–2026). It features the most frequent high-yield medications, antidotes, and
safety protocols with answers in Broadway and comprehensive clinical judgment
rationales. Perfect for original attempts or retakes, this set covers everything from NGN
case priorities to essential drug-drug interactions.
1. A nurse is caring for a client receiving Digoxin. Which of the following
manifestations should the nurse identify as an early sign of toxicity?
A) Hyperkalemia
B) Anorexia and nausea
C) Tachycardia
D) Hypertension
Rationale: Gastrointestinal distress (anorexia, nausea, vomiting) and vision
changes (yellow-green halos) are early warning signs of digoxin toxicity.
2. A client is prescribed Atorvastatin. Which of the following laboratory
values should the nurse monitor?
A) Liver Function Tests (LFTs)
B) International Normalized Ratio (INR)
C) Serum Creatinine
D) Magnesium
Rationale: Statins can cause hepatotoxicity and rhabdomyolysis; LFTs should be
checked at baseline and periodically.
3. A nurse is preparing to administer Heparin subcutaneously. Which of the
following actions should the nurse take?
A) Massage the site after injection to increase absorption.
B) Aspirate for blood return before injecting.
C) Administer the injection 2 inches from the umbilicus.
D) Use a 20-gauge needle.
Rationale: Heparin should be injected into the abdomen, away from the
umbilicus, without aspiration or massaging to prevent bruising.
,4. A client is taking Phenelzine (an MAOI). Which food choice indicates the
client understands the dietary restrictions?
A)
Pepperoni pizza
B)
Smoked salmon
C)
Roasted chicken with potatoes
D)
Aged cheddar cheese
Rationale: MAOIs require a low-tyramine diet to prevent hypertensive crisis.
Roasted chicken is safe; aged, smoked, and fermented foods are not.
5. A nurse is teaching a client about a new prescription for Alendronate for
osteoporosis. Which instruction is the priority?
A) Take the medication with a full glass of milk.
B) Sit upright for 30 minutes after taking the medication.
C) Take the medication right before bedtime.
D) Exercise immediately after taking the pill.
Rationale: Alendronate can cause severe esophagitis. The client must stay
upright and take it with 8 oz of plain water on an empty stomach.
6. Which of the following medications is the antidote for Benzodiazepine
overdose?
A) Naloxone
B) Acetylcysteine
C) Flumazenil
D) Protamine Sulfate
Rationale: Flumazenil is the specific reversal agent for benzodiazepines;
Naloxone is for opioids.
7. A client is prescribed Lithium Carbonate. Which of the following dietary
instructions should the nurse provide?
A) Limit calorie intake to prevent weight gain.
B) Restrict fluid intake to 1 liter per day.
, C) Maintain a consistent intake of dietary sodium.
D) Avoid green leafy vegetables.
Rationale: Lithium is a salt. If sodium levels drop (due to diet or sweating), the
kidneys retain lithium, leading to toxicity.
8. A nurse is assessing a client receiving Magnesium Sulfate IV for
preeclampsia. Which finding should the nurse report immediately?
A) Absent deep tendon reflexes (DTRs)
B) Increased urinary output
C) Respiratory rate of 16/min
D) Fetal heart rate of 140/min
Rationale: Magnesium toxicity causes CNS depression, evidenced by decreased
DTRs, respiratory depression, and oliguria.
9. A client is starting Spironolactone. Which of the following electrolyte
imbalances should the nurse monitor for?
A) Hypokalemia
B) Hyperkalemia
C) Hyponatremia
D) Hypocalcemia
Rationale: Spironolactone is a potassium-sparing diuretic; it can cause the body
to retain dangerous levels of potassium.
10. A nurse is teaching a client about taking Ferrous Sulfate syrup. Which
instruction should be included?
A) Mix the medication with milk.
B) Drink the medication through a straw.
C) Take the medication with an antacid.
D) Expect stools to be light clay-colored.
Rationale: Liquid iron can stain teeth; drinking through a straw bypasses the
teeth. Vitamin C increases absorption, while calcium/dairy decreases it.
11. Which medication is used to treat a "myasthenic crisis"?
A) Neostigmine
B) Atropine
C) Dopamine
D) Scopolamine
Rationale: Cholinesterase inhibitors like Neostigmine increase acetylcholine at
the neuromuscular junction to improve muscle strength.
, 12. A nurse is administering Gentamicin IV. Which of the following adverse
effects is the priority to monitor?
A) Constipation
B) Tinnitus and hearing loss
C) Photosensitivity
D) Nasal congestion
Rationale: Aminoglycosides (Gentamicin) are highly ototoxic and nephrotoxic.
Tinnitus is an early sign of cochlear damage.
13. A client is prescribed Nitroglycerin sublingual tablets for angina. What
should the nurse instruct the client to do if chest pain occurs?
A) Take 3 tablets at once.
B) Place one tablet under the tongue and call emergency services if pain is
not relieved in 5 minutes.
C) Swallow the tablet with a sip of water.
D) Wait 15 minutes before taking a second dose.
Rationale: The protocol is 1 tablet every 5 mins for up to 3 doses; however, the
client must call emergency services after the first dose if pain persists.
14. A client is receiving a Warfarin infusion. Which lab value indicates the
treatment is therapeutic?
A) aPTT of 60 seconds
B) INR of 2.5
C) Platelets of 100,000
D) Hemoglobin of 14 g/dL
Rationale: INR is the standard monitoring tool for Warfarin (target 2.0–3.0); aPTT
is used for Heparin.
15. A nurse is preparing to administer Lispro insulin. When should the nurse
administer this medication?
A) 30 to 60 minutes before a meal.
B) At bedtime.
C) 15 minutes before a meal.
D) Only when the blood glucose is above 200 mg/dL.
Rationale: Lispro is rapid-acting; it has an onset of 15 minutes and should be
given "when the tray is in sight."
16. Which of the following is a common adverse effect of ACE inhibitors like
Lisinopril?
A) Tachycardia
