COVERING PHARMACOKINETICS, ANTIBIOTICS,
CARDIAC, ENDOCRINE & PSYCH MEDS
1. A patient with Chronic Renal Failure is prescribed Gentamicin. Why is this patient
at a higher risk for toxicity?
A. Increased drug metabolism
B. Decreased drug excretion
C. Increased protein binding
D. Rapid first-pass effect
Rationale: Gentamicin is primarily excreted by the kidneys; impaired renal
function leads to drug accumulation and toxic levels.
2. Which medication is considered the first-line treatment for a patient newly
diagnosed with Type 2 Diabetes?
A. Glyburide
B. Metformin
C. Insulin Glargine
D. Pioglitazone
Rationale: Metformin is the preferred initial pharmacological agent due to its
efficacy, low risk of hypoglycemia, and weight-neutral effects.
3. Before administering an opioid analgesic, which vital sign is the priority for the
nurse to assess?
A. Temperature
B. Blood Pressure
C. Respiratory Rate
D. Heart Rate
Rationale: Opioids are CNS depressants that can cause fatal respiratory
depression; a rate below 12 breaths/min usually requires holding the dose.

4. A patient taking Lisinopril develops a persistent, dry cough. Which medication
class is the most appropriate alternative?
A. Beta-Blockers
B. Angiotensin II Receptor Blockers (ARBs)
C. Calcium Channel Blockers
D. Loop Diuretics
Rationale: The "ACE cough" is caused by bradykinin accumulation; ARBs
provide similar cardiovascular benefits without affecting bradykinin.
5. What is the mechanism of action for Phenytoin in the treatment of seizures?
A. Increasing GABA levels
B. Selective inhibition of sodium channels
C. Blocking calcium influx
D. Inhibiting glutamate receptors
Rationale: Phenytoin stabilizes neuronal membranes by delaying the influx of
sodium ions, thereby suppressing repetitive firing of neurons.
6. A patient is prescribed Sildenafil for erectile dysfunction. Which concurrent
medication is strictly contraindicated?
A. Amlodipine
B. Isosorbide Mononitrate
C. Metformin
D. Atorvastatin
Rationale: Nitrates combined with PDE-5 inhibitors can cause a life-threatening
drop in blood pressure due to excessive cGMP accumulation.
7. Which baseline laboratory test is essential before starting a patient on Lithium for
Bipolar Disorder?
A. Liver Function Tests
B. BUN and Creatinine
C. Coagulation Panel
D. Amylase and Lipase
Rationale: Lithium is excreted entirely by the kidneys and has a narrow
therapeutic index; baseline renal function is critical for safe dosing.
8. An elderly patient is at a higher risk for Adverse Drug Events (ADEs) primarily
due to:
A. Increased gastric acidity
,2026 UPDATED QUESTIONS DOWNLOAD
B. Reduced hepatic blood flow and glomerular filtration
C. Increased total body water
D. Faster drug metabolism
Rationale: Aging leads to physiological declines in organ function, which slows
the metabolism and excretion of drugs.
9. Which antidepressant is the best choice for a patient concerned about sexual
dysfunction?
A. Fluoxetine
B. Bupropion
C. Sertraline
D. Venlafaxine
Rationale: Bupropion does not affect serotonin as significantly as SSRIs/SNRIs,
making it much less likely to cause sexual side effects.
10. A patient presents with Atropine poisoning (anticholinergic toxicity). Which drug is
the specific antidote?
A. Naloxone
B. Physostigmine
C. Flumazenil
D. Digibind
Rationale: Physostigmine is an acetylcholinesterase inhibitor that crosses the
blood-brain barrier to reverse central and peripheral anticholinergic effects.
11. When starting Levothyroxine for hypothyroidism, how long does it typically take
to reach a steady state?
A. 24 hours
B. 1 week
C. 4 to 6 weeks
D. 3 months
Rationale: Due to its long half-life (approx. 7 days), it takes several weeks of
consistent dosing to achieve stable serum TSH levels.
12. Which statement by a patient indicates an understanding of taking Alendronate
for osteoporosis?
A. "I will take it with my morning coffee."
B. "I will sit upright for 30 minutes after taking it."
C. "I will take it right before I go to bed."
, 2026 UPDATED QUESTIONS DOWNLOAD
D. "I will take it with a calcium supplement."
Rationale: Bisphosphonates can cause severe esophageal irritation; patients
must remain upright and take it only with plain water on an empty stomach.
13. Which medication is used orally to treat severe, recalcitrant psoriasis?
A. Hydrocortisone
B. Methotrexate
C. Mupirocin
D. Benzoyl Peroxide
Rationale: Methotrexate is a systemic antimetabolite that slows the rapid
proliferation of skin cells in severe psoriasis.
14. A patient on Warfarin has an INR of 7.5 but no active bleeding. Which is the
appropriate intervention?
A. Administer Protamine Sulfate
B. Administer Vitamin K
C. Administer Heparin
D. Increase the Warfarin dose
Rationale: Vitamin K is the direct antagonist for Warfarin; it helps the liver
synthesize clotting factors to lower a dangerously high INR.
15. What is a common side effect of the Alpha-1 blocker Tamsulosin?
A. Hypertension
B. Orthostatic Hypotension
C. Constipation
D. Weight Gain
Rationale: Alpha-blockers relax vascular smooth muscle, which can lead to a
sudden drop in blood pressure when standing.
16. Which antimicrobial is associated with the risk of tendon rupture, especially in
older adults?
A. Amoxicillin
B. Ciprofloxacin
C. Azithromycin
D. Doxycycline
Rationale: Fluoroquinolones carry a black box warning for tendonitis and tendon
rupture.
