## Pharmacology Practice Questions (87-100) **87. A client on doxorubicin (Adriamycin) requires which specific monitoring?** - A. Pulmonary function tests - B. Echocardiogram for cardiac function - C. Liver biopsy - D. Hearing tests **Answer: B. Echocardiogram for cardiac function** *Rationale: Doxorubicin is an anthracycline chemotherapy agent with dose-related cardiotoxicity that can lead to heart failure. Baseline and periodic echocardiograms or MUGA scans are essential to monitor left ventricular ejection fraction. Cumulative doses 550 mg/m² significantly increase cardiomyopathy risk.* **88. A nurse is administering IV immune globulin (IVIG). Which assessment finding requires immediate intervention?** - A. Headache during infusion - B. Flushing - C. Severe back pain and shortness of breath - D. Mild fever **Answer: C. Severe back pain and shortness of breath** *Rationale: Severe back pain, dyspnea, and hypotension may indicate anaphylaxis or a severe infusion reaction. Stop infusion immediately, maintain airway, and notify provider. Headache, flushing, and mild fever are common but require monitoring and possibly slowing the rate.* **89. A client with opioid use disorder is started on methadone. What teaching should the nurse provide?** - A. "You can stop this medication anytime you feel ready." - B. "This medication will cause a euphoric high." - C. "You must take this medication daily as prescribed to prevent withdrawal." - D. "Methadone cannot be combined with any other medications." **Answer: C. "You must take this medication daily as prescribed to prevent withdrawal."** *Rationale: Methadone is a long-acting opioid agonist used for maintenance therapy. It prevents withdrawal symptoms and cravings without producing euphoria when taken at stable doses. Abrupt discontinuation causes withdrawal. Many drug interactions exist, but it can be combined with other medications under monitoring.* **90. A nurse is preparing to administer an IM injection using the ventrogluteal site. Which landmark is correct?** - A. Greater trochanter, anterior iliac spine, and iliac crest - B. Acromion process and deltoid tuberosity - C. Posterior iliac spine and sacrum - D. Midpoint of the lateral thigh **Answer: A. Greater trochanter, anterior iliac spine, and iliac crest** *Rationale: The ventrogluteal site is located by placing the palm on the greater trochanter, index finger on the anterior iliac spine, and middle finger along the iliac crest, forming a V. This site is preferred for IM injections in adults due to lack of major nerves and vessels.* **91. A client on enoxaparin (Lovenox) is scheduled for surgery. When should the nurse hold the preoperative dose?** - A. 4 hours before surgery - B. 8 hours before surgery - C. 12-24 hours before surgery - D. 48 hours before surgery **Answer: C. 12-24 hours before surgery** *Rationale: Enoxaparin should be held 12-24 hours before surgery or neuraxial anesthesia to reduce bleeding and spinal hematoma risk. The exact timing depends on dose (prophylactic vs treatment) and institutional protocol.* **92. A nurse is teaching a client about rifampin. Which statement indicates understanding?** - A. "I need to take this medication with antacids." - B. "My birth control pills may not work while I'm on this medication." - C. "I should take this medication only when I have symptoms." - D. "This medication turns urine blue, which is harmless." **Answer: B. "My birth control pills may not work while I'm on this medication."** *Rationale: Rifampin is a potent CYP450 enzyme inducer that accelerates metabolism of hormonal contraceptives, reducing their effectiveness. Alternative contraception methods are needed. It also causes orange-red (not blue) discoloration of body fluids.* **93. A client with hyperkalemia is receiving IV calcium gluconate. Which assessment finding indicates therapeutic effect?** - A. Increased serum potassium level - B. Resolution of peaked T waves on ECG - C. Decreased blood pressure - D. Increased urine output **Answer: B. Resolution of peaked T waves on ECG** *Rationale: Calcium gluconate stabilizes the cardiac membrane in hyperkalemia, antagonizing the cardiac effects. It does NOT lower serum potassium. Therapeutic effect is improvement in ECG changes (peaked T waves, widened QRS). It provides temporary protection while other measures lower potassium.* **94. A nurse is administering naloxone to a client with respiratory depression. After administration, the client becomes agitated and combative. What is the nurse's priority action?** - A. Administer a sedative - B. Restrain the client - C. Ensure client safety and continue monitoring respirations - D. Discontinue naloxone **Answer: C. Ensure client safety and continue monitoring respirations** *Rationale: Naloxone rapidly reverses opioid effects, causing acute withdrawal symptoms including agitation, pain, and combativeness. Priority is ensuring client and staff safety while continuing to monitor respirations (naloxone duration may be shorter than some opioids). Sedation may be needed but only with caution.* **95. A client on simvastatin (Zocor) reports muscle tenderness and dark urine. What is the priority action?** - A. Encourage increased fluid intake - B. Obtain a creatine kinase (CK) level - C. Administer acetaminophen for pain - D. Reassure the client this is expected **Answer: B. Obtain a creatine kinase (CK) level** *Rationale: These symptoms suggest rhabdomyolysis, a serious adverse effect of statins. The nurse should hold the medication and obtain CK level. Elevated CK confirms rhabdomyolysis. Dark urine indicates myoglobinuria, which can cause kidney damage.* **96. A nurse is administering a vaccine to a 6-month-old infant. Which site and needle length are correct?** - A. Deltoid muscle, 5/8 inch needle - B. Vastus lateralis, 1 inch needle - C. Dorsogluteal, 1.5 inch needle - D. Ventrogluteal, 1 inch needle **Answer: B. Vastus lateralis, 1 inch needle** *Rationale: For infants, the vastus lateralis (anterolateral thigh) is the preferred site. Needle length should be 1 inch to ensure intramuscular deposition. Deltoid is too small in infants. Dorsogluteal is avoided due to proximity to sciatic nerve and underdeveloped muscle.* **97. A client on cyclosporine has a blood pressure of 160/95 mm Hg. What is the nurse's best action?** - A. Administer cyclosporine and notify provider of BP - B. Hold cyclosporine and notify provider - C. Recheck BP in 30 minutes - D. Administer antihypertensive medication **Answer: A. Administer cyclosporine and notify provider of BP** *Rationale: Hypertension is a common adverse effect of cyclosporine but is not a reason to hold the dose (life-sustaining immunosuppression). Administer the dose and notify provider for antihypertensive management. Do not stop immunosuppressants without provider direction.* **98. A client is prescribed ferrous sulfate for iron deficiency anemia. Which statement indicates understanding?** - A. "I should take this medication with milk to prevent stomach upset." - B. "My stools may turn black, which is normal." - C. "I can take this with antacids for better absorption." - D. "This medication will work within 24 hours." **Answer: B. "My stools may turn black, which is normal."** *Rationale: Iron supplements cause harmless dark green or black stools. Clients should be warned to prevent alarm. Iron is best absorbed on empty stomach with vitamin C (orange juice). Avoid milk, antacids, coffee, tea (decrease absorption). Therapeutic effects take weeks.* **99. A nurse is administering IV mannitol to a client with increased intracranial pressure. Which assessment finding indicates therapeutic effect?** - A. Decreased urine output - B. Decreased intracranial pressure - C. Increased blood pressure - D. Increased serum sodium **Answer: B. Decreased intracranial pressure** *Rationale: Mannitol is an osmotic diuretic that draws fluid from brain tissue into vasculature, reducing cerebral edema and ICP. Therapeutic effect is decreased ICP. Monitor for increased urine output (expected), fluid/electrolyte imbalance, and signs of heart failure.* **100. A client on long-term prednisone is scheduled for surgery. What is the priority nursing consideration?** - A. Hold all prednisone doses 24 hours before surgery - B. Administer preoperative stress-dose steroids as ordered - C. Monitor for hyperglycemia only - D. Discontinue prednisone permanently after surgery **Answer: B. Administer preoperative stress-dose steroids as ordered** *Rationale: Long-term corticosteroid use suppresses the HPA axis, impairing the body's ability to respond to surgical stress. Stress-dose steroids are typically administered perioperatively to prevent adrenal crisis. Steroids are tapered, not abruptly discontinued.* --- ## Summary of Key Topics Covered | Category | Question Numbers | Key Drugs | |----------|------------------|-----------| | Cardiovascular | 1,2,9,10,20,26,36,40,56,77,86,95 | Digoxin, Warfarin, Heparin, Furosemide, Statins | | Endocrine | 3,8,12,33,41,53,79,98 | Insulin, Levothyroxine, Metformin, Oral hypoglycemics | | Anti-infectives | 7,29,38,43,63,68,69,92 | Vancomycin, Gentamicin, Rifampin, Ciprofloxacin | | Neurological/Psych | 6,27,46,58,81,83,89 | Lithium, Carbidopa-levodopa, Benzodiazepines, Antipsychotics | | Respiratory | 5,31,49,66 | Albuterol, Montelukast, Salmeterol, Theophylline | | Immunosuppressants | 44,82,97 | Cyclosporine, Azathioprine, Methotrexate | | Chemotherapy | 87 | Doxorubicin | | Vaccines/Immunizations | 57,84,96 | MMR, PPD, Pediatric immunizations | | Administration Techniques | 11,14,18,40,55,63,74,90,96 | IM/SubQ/IV/ID injections, Z-track, Site selection | | Emergency Medications | 13,50,71,94 | Naloxone, Calcium gluconate | --- ## Final Exam Success Strategies Based on the search results and nursing education best practices: 1. **Focus on the Nursing Process** - ATI questions typically follow assessment, intervention, evaluation format 2. **Prioritize Safety** - Questions about holding medications, adverse effects, and contraindications are common 3. **Know Your Calculations** - Dosage calculations appear frequently and are often "gimme" points 4. **Review Lab Values** - Know therapeutic ranges (digoxin 0.5-2.0, lithium 0.6-1.2, INR 2-3, etc.) 5. **Study Drug Interactions** - Grapefruit juice, alcohol, and herb-drug interactions are tested 6. **Practice NGN-style Questions** - Focus on case studies with multiple data points and prioritization ## Pharmacology Practice Questions (87-100) **87.
