D441 Pharmacology - Week 7 Practice Quiz 2026 |WGU
1. A patient with a history of asthma is prescribed a non-selective beta-blocker.
Which side effect is the nurse most concerned about?
A. Bronchospasm
B. Hypertension
C. Bradycardia
D. Hypoglycemia
Answer: A
Rationale: Non-selective beta-blockers block Beta-2 receptors in the lungs, which can lead
to bronchoconstriction and bronchospasm in patients with asthma.
2. Which laboratory value is most important to monitor in a patient receiving
Furosemide (Lasix)?
A. Serum Potassium
B. Serum Sodium
C. Serum Calcium
D. Serum Magnesium
Answer: A
Rationale: Furosemide is a loop diuretic that causes significant loss of potassium;
hypokalemia is a common and dangerous side effect.
,3. What is the therapeutic range for a patient taking Digoxin?
A. 10 to 20 mcg/mL
B. 2.5 to 5.0 ng/mL
C. 0.5 to 2.0 ng/mL
D. 0.1 to 0.5 ng/mL
Answer: C
Rationale: The standard therapeutic range for Digoxin is 0.5 to 2.0 ng/mL. Levels above
this indicate toxicity.
4. A patient is prescribed Warfarin (Coumadin). Which lab test is used to
monitor the effectiveness of this medication?
A. aPTT
B. Bleeding time
C. Platelet count
D. PT/INR
Answer: D
Rationale: Prothrombin Time (PT) and International Normalized Ratio (INR) are used to
monitor Warfarin therapy.
5. What is the specific antidote for Heparin overdose?
A. Vitamin K
B. Glucagon
C. Protamine Sulfate
D. Acetylcysteine
Answer: C
Rationale: Protamine Sulfate is the antidote that neutralizes the effects of Heparin.
, 6. Which medication class is the first-line treatment for chronic heart failure to
prevent cardiac remodeling?
A. Calcium Channel Blockers
B. Loop Diuretics
C. ACE Inhibitors
D. Cardiac Glycosides
Answer: C
Rationale: ACE Inhibitors are proven to reduce mortality and prevent cardiac remodeling
in heart failure patients.
7. A patient taking Spironolactone should be educated to avoid which of the
following?
A. Green leafy vegetables
B. Dairy products
C. Salt substitutes
D. Grapefruit juice
Answer: C
Rationale: Salt substitutes often contain potassium chloride. Since Spironolactone is a
potassium-sparing diuretic, this increases the risk of hyperkalemia.
8. Which side effect is specific to ACE Inhibitors and often leads to the
medication being switched to an ARB?
A. Dry, hacking cough
B. Peripheral edema
C. Constipation
D. Tachycardia
Answer: A
Rationale: ACE inhibitors prevent the breakdown of bradykinin, which can cause a
persistent dry cough in some patients.
