,Q1. A 30-year-old patient with a history of recurrent, unprovoked generalized tonic-clonic seizures currently
on lamotrigine 200 mg twice daily presents with a new-onset rash that is diffuse, erythematous, and includes
target lesions on the palms and soles. Vital signs are normal. Which of the following is the most appropriate
immediate action?
A. Continue lamotrigine and prescribe oral antihistamines for symptomatic relief.
B. Discontinue lamotrigine immediately and refer to emergency department for evaluation.
C. Reduce lamotrigine dose to 100 mg twice daily and add a short course of prednisone.
D. Obtain a serum lamotrigine level and schedule a follow-up in one week.
Correct Answer: B. Discontinue lamotrigine immediately and refer to emergency department for evaluation.
Rationale: The rash with target lesions on palms/soles is concerning for Stevens-Johnson syndrome (SJS), a
life-threatening hypersensitivity reaction associated with lamotrigine. Immediate discontinuation and emergency
evaluation are mandatory. Antihistamines or steroids alone are insufficient, and dose reduction does not mitigate
risk.
Why Wrong:
A - Continuing lamotrigine with antihistamines delays recognition and treatment of potential SJS, which can
rapidly progress.
C - Dose reduction and prednisone do not address the ongoing hypersensitivity reaction and may worsen
outcomes.
D - Obtaining a lamotrigine level is not diagnostic for SJS; prompt discontinuation and referral are critical.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 24; UpToDate: Stevens-Johnson
syndrome.
Q2. Which of the following best explains why a patient with chronic kidney disease (CKD) stage 4 who is
started on enalapril may experience a rapid decline in glomerular filtration rate (GFR) within the first week
of therapy?
A. Enalapril causes afferent arteriolar vasodilation, reducing intraglomerular pressure.
B. Enalapril preferentially dilates the efferent arteriole, decreasing glomerular capillary pressure.
C. Enalapril increases angiotensin II levels, leading to mesangial cell contraction.
D. Enalapril promotes sodium and water retention, increasing extracellular volume.
Correct Answer: B. Enalapril preferentially dilates the efferent arteriole, decreasing glomerular capillary
pressure.
Rationale: ACE inhibitors like enalapril block angiotensin II formation, reducing efferent arteriolar tone. In CKD,
GFR is maintained by angiotensin II-mediated efferent vasoconstriction; removing this support causes a drop in
GFR. Afferent dilation would increase GFR, not decrease. Increased angiotensin II (C) is incorrect because
enalapril decreases it. Sodium/water retention (D) is not a direct effect.
Why Wrong:
A - Afferent arteriolar vasodilation would increase GFR, opposite of the observed decline.
C - Enalapril decreases angiotensin II, not increases it.
D - ACE inhibitors typically reduce aldosterone, leading to mild natriuresis, not retention.

Q3. A 45-year-old patient with type 2 diabetes mellitus and hypertension is currently on metformin 1000 mg
BID and lisinopril 20 mg daily. Hemoglobin A1c is 8.5%, and eGFR is 55 mL/min/1.73 m². According to the
latest ADA standards, which of the following medication additions is most appropriate as initial combination
therapy?
A. Glipizide extended-release 5 mg daily
B. Empagliflozin 10 mg daily
C. Insulin glargine 10 units at bedtime
D. Pioglitazone 15 mg daily
Page 3
, Correct Answer: B. Empagliflozin 10 mg daily
Rationale: The ADA 2026 guidelines recommend SGLT2 inhibitors (e.g., empagliflozin) as first-line add-on to metformin for
patients with CKD (eGFR 25-60) and established ASCVD or high risk, due to cardiorenal benefits. Glipizide increases
hypoglycemia risk and lacks organ protection. Insulin is not first-line for add-on. Pioglitazone may worsen fluid retention and
is less preferred with CKD.
Why Wrong:
A - Sulfonylureas are associated with hypoglycemia and weight gain, and do not provide cardiovascular or renal
protection.
C - Insulin is typically reserved for severe hyperglycemia or when other agents fail; not first add-on in this scenario.
D - Pioglitazone can cause fluid retention and may increase heart failure risk; not preferred with CKD stage 3.

1), S112-S127.
Q4. A patient with a history of opioid use disorder is started on buprenorphine/naloxone for maintenance
therapy. After the first dose, the patient reports feeling 'more withdrawal symptoms.' Which of the following
is the most likely explanation?
A. Naloxone precipitated withdrawal due to rapid absorption.
B. Buprenorphine partially displaced full agonists from mu receptors, inducing precipitated withdrawal.
C. Buprenorphine is a full antagonist at mu receptors, causing immediate withdrawal.
D. The patient is experiencing a placebo effect due to anxiety about treatment.
Correct Answer: B. Buprenorphine partially displaced full agonists from mu receptors, inducing precipitated
withdrawal.
Rationale: Buprenorphine is a partial mu agonist with high receptor affinity. If given when full agonists (e.g.,
heroin, morphine) are still bound, it can displace them and precipitate withdrawal. Naloxone has poor sublingual
bioavailability and is not the cause. Buprenorphine is not a full antagonist. Placebo effect is unlikely given the
mechanism.
Why Wrong:
A - Naloxone in sublingual buprenorphine/naloxone has minimal systemic absorption and does not precipitate
withdrawal.
C - Buprenorphine is a partial agonist, not an antagonist; it produces some agonist effect.
D - The phenomenon is pharmacologically predictable, not primarily psychological.

392(10), 987-998.
Q5. A 28-year-old patient presents with acute onset of severe, colicky right flank pain radiating to the groin,
associated with nausea and hematuria. CT scan reveals a 5 mm radiopaque stone in the proximal right ureter
with mild hydronephrosis. Which of the following management strategies is most appropriate as initial
treatment?
A. Immediate ureteroscopic lithotripsy
B. Trial of passage with tamsulosin and analgesics
C. Extracorporeal shock wave lithotripsy (ESWL) within 24 hours
D. Percutaneous nephrostomy tube placement
Correct Answer: B. Trial of passage with tamsulosin and analgesics
Rationale: Stones "d5 mm in the proximal ureter have a high likelihood of spontaneous passage. Medical expulsive
therapy (tamsulosin) and adequate analgesia are first-line. Ureteroscopy or ESWL is reserved for stones >5 mm,
failure to pass, or complications. Nephrostomy is indicated for obstruction with infection or renal failure.
Why Wrong:
A - Ureteroscopic intervention is not first-line for small, potentially passable stones without indications for
urgent removal.
