ALREADY GRADED A+
This comprehensive test bank provides 400 multiple-choice questions covering
essential NURS 617 pharmacotherapeutics concepts for advanced nursing
practice. Each question includes the correct answer and a detailed rationale to
reinforce learning and clinical reasoning. The content spans major drug
classes including cardiovascular agents (beta-blockers, ACE inhibitors,
diuretics, statins), endocrine medications (levothyroxine, antidiabetic agents,
SGLT-2 inhibitors, GLP-1 receptor agonists), bone health medications
(bisphosphonates), psychiatric drugs (SSRIs, benzodiazepines), and pain
management (opioids). Topics also cover adverse effects, drug interactions,
contraindications, patient education, and special population considerations.
This resource is ideal for exam preparation, clinical reference, and
strengthening pharmacological knowledge for safe prescribing and
medication management in advanced nursing practice.
1. A patient with hyperthyroidism is prescribed methimazole. What is the primary
mechanism of action of this medication?
A. Blocks the release of thyroid hormone from the thyroid gland
B. Inhibits the synthesis of thyroid hormone by blocking thyroid peroxidase
C. Destroys thyroid tissue through radioactive uptake
D. Blocks the peripheral conversion of T4 to T3
Correct Answer: B
Rationale: Methimazole is a thioamide antithyroid medication that inhibits thyroid
hormone synthesis by blocking the enzyme thyroid peroxidase. This prevents the
iodination of tyrosine residues on thyroglobulin, thereby reducing the production
of T3 and T4. It does not block release of preformed hormone, which is why onset
of action is delayed until existing stores are depleted. Radioactive iodine destroys
thyroid tissue, while medications like propylthiouracil also block peripheral
conversion of T4 to T3 .
2. Which thyroid medication is most associated with cardiotoxicity?
,A. Levothyroxine
B. Liothyronine
C. Methimazole
D. Propylthiouracil
Correct Answer: B
Rationale: Liothyronine is the most cardiotoxic thyroid medication because it is the
active form of T3. The rapid onset of action and higher potency of liothyronine can
cause significant cardiac stimulation, palpitations, tachycardia, and even
arrhythmias, particularly in older adults or those with underlying cardiac disease.
This effect is more pronounced than with levothyroxine, which is a prodrug that is
converted to T3 more gradually .
3. Which thyroid hormone preparation has the disadvantage of lacking content
stability?
A. Levothyroxine
B. Liothyronine
C. Liotrix
D. Desiccated thyroid
Correct Answer: C
Rationale: Liotrix is a synthetic combination of T4 and T3 in a fixed 4:1 ratio. It
has been associated with content stability issues, meaning the potency and
consistency of the medication can vary between batches. This lack of stability can
lead to unpredictable therapeutic effects and difficulty in achieving consistent
hormone levels. Levothyroxine, in contrast, has excellent stability and consistent
potency when properly stored .
4. What is the correct method for administering bisphosphonates such as
alendronate?
A. On an empty stomach with a full 8 ounces of water; remain upright for 30-60
minutes
B. With food to minimize gastrointestinal upset
C. At bedtime with milk to enhance absorption
D. With orange juice to improve bioavailability
Correct Answer: A
Rationale: Bisphosphonates, such as alendronate, must be taken on an empty
stomach with a full 8 ounces of plain water, and the patient must remain upright
(sitting or standing) for at least 30-60 minutes after taking the dose. This
,administration method prevents esophageal irritation and ensures adequate
absorption. Taking with food, milk, or other beverages significantly reduces
absorption and increases the risk of esophagitis .
5. Which medication class used to treat osteoporosis can cause severe esophagitis
and possible osteonecrosis of the jaw?
A. Selective estrogen receptor modulators
B. Calcitonin
C. Bisphosphonates
D. Parathyroid hormone analogs
Correct Answer: C
Rationale: Bisphosphonates are associated with two significant adverse effects:
severe esophagitis and osteonecrosis of the jaw. Esophagitis occurs due to local
irritation if the medication is not taken correctly, while osteonecrosis of the jaw is a
rare but serious complication seen with long-term use, particularly following dental
procedures. These risks necessitate careful patient education on proper
administration and dental monitoring .
6. Hyperkalemia is a side effect of which of the following drugs?
A. Chlorthalidone
B. Furosemide
C. Hydrochlorothiazide
D. Spironolactone
Correct Answer: D
Rationale: Spironolactone is a potassium-sparing diuretic that works by
competitively inhibiting aldosterone receptors in the distal convoluted tubule. This
mechanism promotes sodium and water excretion while conserving potassium,
which can lead to hyperkalemia, especially in patients with renal impairment or
those taking other potassium-elevating medications. In contrast, loop diuretics like
furosemide and thiazides like hydrochlorothiazide and chlorthalidone cause
potassium loss and can lead to hypokalemia .
7. Inhalational forms of a drug are absorbed very quickly because:
A. There are no natural barriers to absorption in the lungs
B. The lungs have a large surface area with extensive vascular supply
C. Inhaled drugs are metabolized more slowly than oral drugs
D. The pulmonary circulation has high protein binding capacity
, Correct Answer: B
Rationale: Inhalational drugs are absorbed rapidly because the lungs have an
enormous surface area (approximately 75-100 square meters) with a rich vascular
network that allows for rapid and efficient absorption into the systemic circulation.
The alveolar-capillary membrane is very thin, facilitating direct passage of drug
molecules into the bloodstream without significant first-pass metabolism, unlike
oral medications that must pass through the liver .
8. A patient with osteoporosis is prescribed alendronate. Which instruction is most
important to include in patient teaching?
A. "Take this medication with breakfast to reduce stomach upset"
B. "Take this medication at bedtime with a glass of milk"
C. "Swallow the tablet whole with plain water and remain upright for at least 30
minutes"
D. "If you miss a dose, take two tablets the next day to catch up"
Correct Answer: C
Rationale: The most important teaching point for alendronate is to swallow the
tablet whole with plain water and remain upright for at least 30 minutes. This
prevents esophageal irritation and ensures proper absorption. Taking with food or
milk reduces absorption, and doubling a dose is never recommended. The patient
should not lie down after taking the medication to reduce the risk of esophagitis .
9. Which of the following is a contraindication to the use of bisphosphonates?
A. Hypocalcemia
B. Renal impairment with creatinine clearance <35 mL/min
C. History of peptic ulcer disease
D. All of the above
Correct Answer: D
Rationale: Bisphosphonates are contraindicated in patients with hypocalcemia
because they can further lower serum calcium levels. Renal impairment (creatinine
clearance <35 mL/min) is a contraindication because these medications are
excreted by the kidneys and can accumulate, increasing the risk of toxicity. History
of peptic ulcer disease or other esophageal disorders that delay esophageal
emptying is also a relative contraindication due to the risk of esophageal irritation
and ulceration .
10. A patient is prescribed a beta-blocker for hypertension. What is the primary
mechanism by which beta-blockers exert their therapeutic effects?
