WGU D116 Final Exam Guide | Verified 2025/2026 Q&A | 700 Questions | 100% Accurate | Advance with Confidence Question 1 What is the primary mechanism of action for beta-blockers?

• Increase heart rate
• Block beta-adrenergic receptors to reduce heart rate and blood

pressure

• Stimulate alpha receptors
• Enhance potassium excretion

Rationale: Beta-blockers inhibit the effects of catecholamines, reducing cardiac workload.Question 2 Which drug class is contraindicated in patients with a sulfa allergy?

• ACE inhibitors
• Sulfonamides
• Beta-blockers
• Statins

Rationale: Sulfonamides contain a sulfa moiety, posing a risk of allergic reaction.Question 3 What is the half-life of acetaminophen?

• 2-4 hours
• 2-3 hours
• 6-8 hours
• 10-12 hours

Rationale: Acetaminophen’s half-life allows for dosing every 4-6 hours. 1 / 4

Question 4 Which adverse effect is most associated with loop diuretics?

• Hypokalemia
• Hypokalemia
• Hypernatremia
• Hypercalcemia

Rationale: Loop diuretics increase potassium excretion, leading to hypokalemia.

Question 5 What is the first-line treatment for hypertension in a patient with diabetes?

• Thiazide diuretics
• ACE inhibitors
• Calcium channel blockers
• Beta-blockers

Rationale: ACE inhibitors protect renal function in diabetic patients.

Question 6 Which drug requires monitoring for QT prolongation?

• Metformin
• Amiodarone
• Ibuprofen
• Levothyroxine

Rationale: Amiodarone can prolong QT interval, increasing arrhythmia risk.

Question 7 What is the primary site of action for opioids?

• Peripheral nerves
• Central nervous system
• Adrenal glands
• Liver

Rationale: Opioids act on mu-opioid receptors in the CNS for pain relief.

Question 8 Which condition is a contraindication for NSAID use?

• Mild headache
• Active peptic ulcer disease
• Hypertension
• Asthma

Rationale: NSAIDs can exacerbate ulcers due to gastric irritation.

Question 9 What is the therapeutic range for digoxin?

• 0.5-1.0 ng/mL
• 0.5-2.0 ng/mL
• 2.5-3.0 ng/mL
• 4.0-5.0 ng/mL

Rationale: Levels above 2.0 ng/mL increase toxicity risk.

Question 10 Which drug class is used to treat type 2 diabetes by increasing insulin sensitivity?

• Sulfonylureas
• Thiazolidinediones
• Biguanides 2 / 4

• Alpha-glucosidase inhibitors

Rationale: Thiazolidinediones enhance insulin action in peripheral tissues.

Question 11 What is a common side effect of statins?

• Hypoglycemia
• Myopathy
• Hyperkalemia
• Bradycardia

Rationale: Muscle pain or weakness is a known statin side effect.

Question 12 Which antibiotic is contraindicated in patients with myasthenia gravis?

• Amoxicillin
• Fluoroquinolones
• Cephalexin
• Azithromycin

Rationale: Fluoroquinolones can worsen muscle weakness.

Question 13 What is the mechanism of action of warfarin?

• Inhibits platelet aggregation
• Inhibits vitamin K-dependent clotting factors
• Activates fibrinolysis
• Increases thrombin production

Rationale: Warfarin prevents clot formation by blocking vitamin K.

Question 14 Which drug is used to reverse opioid overdose?

• Flumazenil
• Naloxone
• Atropine
• Epinephrine

Rationale: Naloxone competitively binds opioid receptors.

Question 15 What is the primary concern with long-term corticosteroid use?

• Hypoglycemia
• Adrenal suppression
• Hyperkalemia
• Bradycardia

Rationale: Prolonged use suppresses the hypothalamic-pituitary-adrenal axis.

Question 16 Which drug class is first-line for treating acute gout?

• Corticosteroids
• Nonsteroidal anti-inflammatory drugs (NSAIDs)
• Opioids
• Antihistamines

Rationale: NSAIDs reduce inflammation and pain in acute gout.

Question 17 What is the antidote for heparin overdose? 3 / 4

• Vitamin K
• Protamine sulfate
• Naloxone
• Flumazenil

Rationale: Protamine neutralizes heparin’s anticoagulant effects.

Question 18 Which condition requires caution when prescribing beta-blockers?

• Hypothyroidism
• Asthma
• Hyperlipidemia
• Osteoporosis

Rationale: Beta-blockers can cause bronchoconstriction in asthmatics.

Question 19 What is the primary action of diuretics in heart failure?

• Increase blood pressure
• Reduce fluid overload
• Enhance cardiac contractility
• Dilate coronary arteries

Rationale: Diuretics decrease preload by removing excess fluid.

Question 20 Which drug is contraindicated in pregnancy due to teratogenic effects?

• Acetaminophen
• Isotretinoin
• Metoprolol
• Insulin

Rationale: Isotretinoin can cause severe birth defects.

Question 21 What is the primary site of metabolism for most drugs?

• Kidneys
• Liver
• Lungs
• Skin

Rationale: The liver processes drugs via cytochrome P450 enzymes.

Question 22 Which drug is used to treat status epilepticus?

• Carbamazepine
• Lorazepam
• Phenytoin
• Valproic acid

Rationale: Lorazepam acts quickly to stop seizures.

Question 23 What is a common adverse effect of chemotherapy?

• Hypoglycemia
• Nausea and vomiting
• Hypernatremia
• Bradycardia

Rationale: Chemotherapy often causes gastrointestinal distress.
