NU 641 Advanced Clinical Pharmacology Exam 3 Questions and
Answers and Explanations | Latest - Regis
1. A patient is prescribed Metformin for Type 2 Diabetes. Which of the following
is a primary contraindication for this medication?
A. History of hypertension
B. Body Mass Index (BMI) greater than 30
C. Renal impairment with GFR < 30 mL/min
D. Age over 65 years
Answer: C
Explanation: Metformin is contraindicated in patients with severe renal impairment (GFR
< 30 mL/min) due to the increased risk of lactic acidosis.
2. Which education point is essential for a patient starting Levothyroxine for
hypothyroidism?
A. Take the medication with a full meal to increase absorption.
B. Take the medication on an empty stomach, 30-60 minutes before breakfast.
C. Take the medication at bedtime with a glass of milk.
D. Expect symptoms to resolve within 24 hours of the first dose.
Answer: B
,Explanation: Levothyroxine should be taken on an empty stomach in the morning to
ensure optimal and consistent absorption, as food and other medications can interfere with
it.
3. A patient taking an SSRI for depression presents with agitation, confusion,
tachycardia, and muscle rigidity. What should the clinician suspect?
A. Neuroleptic Malignant Syndrome
B. Tardive Dyskinesia
C. Serotonin Syndrome
D. Anticholinergic Crisis
Answer: C
Explanation: Serotonin syndrome is a potentially life-threatening condition caused by
excess serotonin, characterized by mental status changes, autonomic hyperactivity, and
neuromuscular abnormalities.
4. Which laboratory test must be monitored closely for a patient taking
Clozapine?
A. Absolute Neutrophil Count (ANC)
B. Serum Potassium
C. Thyroid Stimulating Hormone (TSH)
D. Prothrombin Time (PT)
Answer: A
,Explanation: Clozapine carries a black box warning for agranulocytosis; therefore, regular
monitoring of the ANC is required by law.
5. What is the therapeutic serum level range for Lithium in the maintenance
phase of bipolar disorder?
A. 0.1 to 0.5 mEq/L
B. 2.5 to 3.5 mEq/L
C. 1.5 to 2.0 mEq/L
D. 0.6 to 1.2 mEq/L
Answer: D
Explanation: The standard therapeutic range for maintenance lithium therapy is generally
0.6 to 1.2 mEq/L. Levels above 1.5 mEq/L are considered toxic.
6. Which medication is an appropriate first-line treatment for a patient with
newly diagnosed Type 2 Diabetes and a history of Atherosclerotic
Cardiovascular Disease (ASCVD)?
A. Glipizide
B. Pioglitazone
C. Sitagliptin
D. Empagliflozin (SGLT2 inhibitor)
Answer: D
, Explanation: SGLT2 inhibitors like Empagliflozin have proven cardiovascular benefits and
are recommended for patients with DM2 and ASCVD.
7. A patient is prescribed Valproic Acid for seizures. Which of the following is a
potential serious side effect?
A. Hepatotoxicity
B. Pulmonary fibrosis
C. Acute renal failure
D. Gingival hyperplasia
Answer: A
Explanation: Valproic acid is associated with risk of hepatotoxicity and pancreatitis; liver
function tests should be monitored.
8. Which of the following describes the mechanism of action of Alendronate?
A. Stimulates osteoblast activity
B. Inhibits osteoclast-mediated bone resorption
C. Increases intestinal calcium absorption
D. Acts as a selective estrogen receptor modulator
Answer: B
Explanation: Alendronate is a bisphosphonate that binds to bone hydroxyapatite and
inhibits osteoclast activity, thereby reducing bone turnover.
