(Wilkes NSG533 Final Exam 2026)
1. A patient is prescribed a medication that is known to be a highly protein-bound drug. If the
patient’s albumin level is significantly low, what is the primary pharmacological concern?
A. The drug will be excreted more slowly by the kidneys.
B. There will be an increase in the free, active fraction of the drug.
C. The drug will have a decreased volume of distribution.
D. Absorption from the gastrointestinal tract will be inhibited.
Answer: B
Rationale: Low albumin levels result in fewer binding sites for highly protein-bound
medications, which leads to a higher concentration of the unbound or ‘free’ drug in the
plasma. This free fraction is the pharmacologically active component, which can lead to
increased therapeutic effects or toxicity. Clinicians must monitor such patients closely and
potentially adjust dosages based on free drug levels rather than total levels.
2. Which of the following describes the mechanism of action of ACE inhibitors in the
management of hypertension and heart failure?
A. Directly antagonizing the AT1 receptor sites.
,B. Blocking the conversion of Angiotensin I to Angiotensin II.
C. Inhibiting the release of renin from the juxtaglomerular cells.
D. Preventing the breakdown of bradykinin to increase vasodilation.
Answer: B
Rationale: ACE inhibitors work by inhibiting the angiotensin-converting enzyme, which
prevents the conversion of Angiotensin I into the potent vasoconstrictor Angiotensin II. By
reducing Angiotensin II levels, these drugs promote vasodilation and decrease aldosterone
secretion, which helps lower blood pressure and reduce preload/afterload in heart failure.
The accumulation of bradykinin is a side effect of this process, which often contributes to
the characteristic dry cough associated with these medications.
3. A 65-year-old male with a history of asthma is diagnosed with hypertension. Which of the
following beta-blockers would be the most appropriate choice for this patient?
A. Propranolol
B. Metoprolol
C. Nadolol
D. Timolol
Answer: B
Rationale: Metoprolol is a cardioselective beta-1 antagonist, meaning it preferentially
blocks receptors in the heart rather than beta-2 receptors in the lungs. In patients with
,asthma or COPD, non-selective beta-blockers like propranolol can cause
bronchoconstriction by blocking beta-2 receptors, potentially precipitating an asthma
attack. While cardioselectivity is dose-dependent, Metoprolol is generally safer for patients
with respiratory comorbidities compared to non-selective agents.
4. When prescribing Warfarin (Coumadin), the clinician must educate the patient on the
importance of maintaining a consistent intake of which vitamin?
A. Vitamin C
B. Vitamin K
C. Vitamin B12
D. Vitamin D
Answer: B
Rationale: Warfarin acts as a Vitamin K antagonist, inhibiting the synthesis of Vitamin K-
dependent clotting factors II, VII, IX, and X. Sudden increases in Vitamin K intake (e.g., from
green leafy vegetables) can overcome the inhibitory effect of Warfarin, leading to a sub-
therapeutic INR and increased risk of clotting. Conversely, a sudden decrease in Vitamin K
can increase the risk of bleeding, making consistent dietary habits essential for stable
anticoagulation.
5. Which medication is considered the first-line pharmacological treatment for Type 2
Diabetes Mellitus, provided there are no contraindications?
A. Glipizide
, B. Sitagliptin
C. Pioglitazone
D. Metformin
Answer: D
Rationale: Metformin is the gold standard for initial therapy in Type 2 Diabetes due to its
efficacy in lowering HbA1c, its low risk of hypoglycemia, and its weight-neutral or weight-
loss benefits. It primarily works by decreasing hepatic glucose production and improving
insulin sensitivity in peripheral tissues. According to ADA guidelines, it should be started at
diagnosis unless the patient has contraindications like severe renal impairment (eGFR < 30
mL/min).
6. A patient is taking a ‘statin’ medication for hyperlipidemia. Which laboratory test is most
critical to monitor if the patient reports new-onset muscle pain?
A. Creatine Kinase (CK)
B. Serum Potassium
C. Blood Urea Nitrogen (BUN)
D. Prothrombin Time (PT)
Answer: A
Rationale: Statins can cause myopathy, which in rare cases can progress to life-threatening
rhabdomyolysis. Monitoring Creatine Kinase (CK) levels is necessary to assess the degree
