Competencies | 2026 Latest Version Graded A+
1.
A 58-year-old male with a history of hypertension and type 2 diabetes
presents for follow-up. He is currently taking lisinopril 20 mg daily. He
reports a persistent dry cough that has worsened over the past month and
is interfering with his sleep. His blood pressure is well controlled at 124/78
mmHg. The provider suspects the cough is medication-related. Which of
the following is the most appropriate next step in management?
A. Continue lisinopril and add a cough suppressant
B. Discontinue lisinopril and initiate losartan
C. Reduce lisinopril dose to 10 mg
D. Switch to a calcium channel blocker
👉 Answer: B. Discontinue lisinopril and initiate losartan
Rationale:
ACE inhibitors like lisinopril increase bradykinin levels, leading to a dry,
persistent cough. This side effect is not dose-dependent and will not
improve with dose reduction. The best alternative is an ARB (like losartan),
which provides similar cardiovascular and renal protection without
,increasing bradykinin. Adding a cough suppressant does not address the
root cause.
2.
A 72-year-old female with chronic kidney disease (eGFR 32 mL/min) and
heart failure is prescribed metformin for newly diagnosed type 2 diabetes.
During medication review, the nurse practitioner recognizes a potential
safety concern. What is the most appropriate action?
A. Continue metformin without changes
B. Reduce dose by half
C. Discontinue metformin due to lactic acidosis risk
D. Add insulin therapy only at night
👉 Answer: C. Discontinue metformin due to lactic acidosis risk
Rationale:
Metformin is contraindicated in patients with significantly reduced renal
function (eGFR <30, caution <45) due to increased risk of lactic acidosis,
a rare but potentially fatal condition. In this patient with eGFR 32,
continuation is unsafe. Alternative therapies should be considered.
3.
A 45-year-old patient with major depressive disorder is started on
sertraline. Two weeks later, the patient reports no improvement in
symptoms and asks to switch medications. What is the best response by the
provider?
A. Discontinue sertraline and start another SSRI immediately
B. Increase dose immediately
C. Educate the patient that full therapeutic effects may take 4–6 weeks
D. Add a benzodiazepine
,👉 Answer: C. Educate the patient that full therapeutic effects may take
4–6 weeks
Rationale:
SSRIs such as sertraline require 4–6 weeks (sometimes up to 8 weeks) to
reach full therapeutic effect. Early discontinuation is inappropriate unless
side effects occur. Patient education is critical to improve adherence.
4.
A 60-year-old male on warfarin therapy for atrial fibrillation presents with
bleeding gums and a nosebleed. His INR is 5.2. What is the most
appropriate initial intervention?
A. Continue warfarin and recheck INR in 24 hours
B. Hold warfarin and administer vitamin K
C. Increase vitamin K intake through diet
D. Switch to aspirin
👉 Answer: B. Hold warfarin and administer vitamin K
Rationale:
An INR >5 with signs of bleeding indicates over-anticoagulation. The
priority is to reverse warfarin effects using vitamin K and hold further
doses. This prevents serious bleeding complications.
5.
A 25-year-old female presents with a urinary tract infection. She is
prescribed trimethoprim-sulfamethoxazole. She reports a severe sulfa
allergy. What is the best alternative?
A. Ciprofloxacin
B. Amoxicillin
, C. Nitrofurantoin
D. Doxycycline
👉 Answer: C. Nitrofurantoin
Rationale:
Nitrofurantoin is a first-line treatment for uncomplicated UTIs and is
safe in patients with sulfa allergies. TMP-SMX must be avoided due to risk
of hypersensitivity reactions.
6.
A patient with asthma is prescribed propranolol for migraine prevention.
Shortly after starting therapy, the patient develops wheezing and shortness
of breath. What explains this reaction?
A. Drug allergy
B. Beta-1 receptor stimulation
C. Beta-2 receptor blockade
D. Histamine release
👉 Answer: C. Beta-2 receptor blockade
Rationale:
Propranolol is a non-selective beta-blocker that blocks both β1 and β2
receptors. Blocking β2 receptors in the lungs causes bronchoconstriction,
worsening asthma symptoms.
7.
A patient taking simvastatin reports muscle pain and weakness. Lab results
show elevated creatine kinase levels. What is the priority action?
A. Continue medication and monitor
B. Reduce dose
