NCLEX Questions - Pharmacology (with Rationales)

Pharmacology is one of the most crucial subjects for nursing students preparing for the NCLEX-RN and NCLEX-PN exams. A strong grasp of medications, their mechanisms, indications, contraindications, and side effects is essential to ensuring patient safety and effective clinical decision-making. Utilizing NCLEX questions pharmacology with rationales PDF resources, as well as interactive tools like NCLEX questions pharmacology with rationales Quizlet, can significantly enhance retention and understanding.

Understanding NCLEX Pharmacology Questions

The pharmacology section of the NCLEX is designed to assess a nurse's ability to safely administer medications and manage their effects. Questions may involve multiple-choice formats, alternative response items (such as select-all-that-apply or prioritization questions), and case studies that require critical thinking. Resources like Pharmacology exam questions and answers PDF can provide a structured review, allowing candidates to familiarize themselves with commonly tested drug classes and clinical applications.

Common Topics in NCLEX Pharmacology Questions

1. Autonomic Nervous System Medications

• Beta-blockers (e.g., metoprolol, propranolol) and their impact on heart rate and blood pressure.

• Cholinergic and anticholinergic drugs, including their effects on smooth muscle and glandular activity.

2. Cardiovascular Medications

• ACE inhibitors and their role in blood pressure regulation.

• Diuretics such as furosemide and their effects on electrolyte balance.

• Antiarrhythmics like amiodarone and their implications for cardiac rhythm management.

3. Central Nervous System Drugs

• Benzodiazepines (e.g., lorazepam) for anxiety and seizure control.

• Antidepressants, including SSRIs and tricyclics, along with their side effect profiles.

• Opioid analgesics and considerations for pain management and dependency.

4. Endocrine Medications

• Insulin therapy in diabetes management, including different types of insulin and their onset times.

• Thyroid medications like levothyroxine and their monitoring parameters.

5. Antibiotics and Antimicrobial Therapy

• Common classifications such as penicillins, cephalosporins, and fluoroquinolones.

• Mechanisms of action and bacterial resistance considerations.

6. Gastrointestinal Medications

• Proton pump inhibitors (e.g., omeprazole) for GERD management.

• Laxatives and stool softeners, including their indications and contraindications.

7. Chemotherapy and Immunosuppressants

• Side effects of cytotoxic drugs, such as myelosuppression and nausea.

• Considerations for immunosuppressants in transplant patients.

Sample NCLEX Pharmacology Questions with Rationales

Question 1: Cardiovascular Medications

A nurse is administering metoprolol to a patient with hypertension. Which assessment finding would require immediate intervention?

A) Heart rate of 58 bpm B) Blood pressure of 130/85 mmHg C) Complaints of fatigue D) Patient reports dizziness upon standing

Correct Answer: A

Rationale: Beta-blockers like metoprolol can cause bradycardia. A heart rate below 60 bpm requires reassessment before administration, as further reduction could lead to symptomatic hypotension or heart block.

Question 2: Insulin Therapy

A patient with type 1 diabetes receives rapid-acting insulin at 0730. At what time should the nurse assess for peak effects of this medication?

A) 0745 B) 0800-0930 C) 1000-1200 D) 1200-1400

Correct Answer: B

Rationale: Rapid-acting insulins, such as lispro and aspart, peak within 30-90 minutes post-administration, requiring close monitoring for signs of hypoglycemia.

Question 3: Antibiotics

A patient receiving gentamicin reports tinnitus and dizziness. What is the nurse’s priority action?

A) Encourage fluid intake B) Continue the medication as prescribed C) Report findings to the healthcare provider D) Administer an anti-nausea medication

Correct Answer: C

Rationale: Aminoglycosides like gentamicin can cause ototoxicity, presenting as tinnitus and vertigo. Immediate intervention is needed to prevent permanent hearing loss.

Question 4: Pain Management

A nurse is preparing to administer morphine IV to a post-operative patient. Which of the following assessments is most critical prior to administration?

A) Heart rate B) Oxygen saturation and respiratory rate C) Pain score D) Blood pressure

Correct Answer: B

Rationale: Opioids can cause respiratory depression. Monitoring oxygen saturation and respiratory rate ensures safe administration.

Below are sample Questions and Answers:

1. A nurse is caring for a client
with hyperparathyroidism and
notes that the client's serum
calcium level is 13 mg/dL.
Which medication should the
nurse prepare to administer as
prescribed to the client?
 1. Calcium chloride
 2. Calcium gluconate
 3. Calcitonin (Miacalcin)
 4. Large doses of vitamin D
3. Calcitonin (Miacalcin)
Rationale:
The normal serum calcium level is 8.6 to
10.0 mg/dL. This client is experiencing hypercalcemia. Calcium gluconate and calcium chloride are medications used for the
treatment of tetany, which occurs as a result of acute hypocalcemia. In hypercalcemia, large doses of vitamin D need to
be avoided. Calcitonin, a thyroid hormone,
decreases the plasma calcium level by inhibiting bone resorption and lowering the
serum calcium concentration.
2. Oral iron supplements are prescribed for a 6-year-old child
with iron deficiency anemia.
The nurse instructs the mother to administer the iron with
which best food item?
 1. Milk
 2. Water
 3. Apple juice
 4. Orange juice
4. Orange juice
Rationale:
Vitamin C increases the absorption of iron
by the body. The mother should be instructed to administer the medication with a citrus fruit or a juice that is high in vitamin
C. Milk may affect absorption of the iron.
Water will not assist in absorption. Orange
juice contains a greater amount of vitamin
C than apple juice.
3. Salicylic acid is prescribed for
a client with a diagnosis of
psoriasis. The nurse monitors
the client, knowing that which
of the following would indicate
the presence of systemic toxicity from this medication?
 1. Tinnitus
 2. Diarrhea
 3. Constipation
 4. Decreased respirations
1. Tinnitus
Rationale:
Salicylic acid is absorbed readily through
the skin, and systemic toxicity (salicylism)
can result. Symptoms include tinnitus,
dizziness, hyperpnea, and psychological
disturbances. Constipation and diarrhea
are not associated with salicylism.
4. A client with severe acne is
seen in the clinic and the health
1. Vitamin A
