Question 1: Pharmacology
A client with asthma is prescribed inhaled fluticasone and albuterol. Which teaching should the nurse provide to ensure optimal therapeutic effect and risk reduction?
- A. “Use the fluticasone inhaler first, then the albuterol inhaler 5 minutes later.”
- B. “Use both inhalers only when you feel short of breath.”
- C. “Use the albuterol inhaler before the fluticasone, then rinse your mouth afterward.”
- D. “Stop the fluticasone if you notice your heart rate increasing.”
Show Answer & Rationale
Answer: C. “Use the albuterol inhaler before the fluticasone, then rinse your mouth afterward.”
Rationale: The nurse educates about medications and expected actions; a short-acting bronchodilator is used before an inhaled corticosteroid to open airways, and rinsing the mouth after fluticasone decreases the risk of oral candidiasis.
Question 2: Pharmacology
An adolescent with rheumatoid arthritis is receiving weekly subcutaneous methotrexate. Which finding requires the nurse to contact the primary health care provider before administering the next dose?
- A. Reports of mild nausea after the last injection
- B. Platelet count 90,000/mm³
- C. Taking folic acid daily as prescribed
- D. Use of a calendar to track injection dates
Show Answer & Rationale
Answer: B. Platelet count 90,000/mm³
Rationale: The nurse must review lab results and recognize contraindications; thrombocytopenia is a serious adverse effect of methotrexate and increases bleeding risk, so the medication should be held and the provider notified.
Question 3: Pharmacology
A pregnant client at 36 weeks’ gestation is prescribed labetalol for chronic hypertension. Which instruction should the nurse prioritize during medication teaching?
- A. “Take this medication only when you feel a headache starting.”
- B. “Check your blood pressure at home and report dizziness or fainting.”
- C. “Avoid all physical activity while you are taking this medicine.”
- D. “Stop taking the medication if your blood pressure returns to normal.”
Show Answer & Rationale
Answer: B. “Check your blood pressure at home and report dizziness or fainting.”
Rationale: The nurse promotes health and reduces risk by teaching self-monitoring; labetalol can cause hypotension and bradycardia, so the client should regularly check blood pressure and report symptoms of low blood pressure.
Question 4: Pharmacology
An older adult with atrial fibrillation is taking apixaban. Which client statement indicates that further teaching is needed?
- A. “I will use an electric razor instead of a blade.”
- B. “I will let my dentist know I take this medicine before any procedure.”
- C. “If I miss a dose, I will double the next one to stay protected.”
- D. “I will call my provider if I notice blood in my urine or stool.”
Show Answer & Rationale
Answer: C. “If I miss a dose, I will double the next one to stay protected.”
Rationale: The nurse educates about safe use of high-risk medications; doses of direct oral anticoagulants should not be doubled when missed because this increases bleeding risk, so the client needs further instruction on what to do after a missed dose.
Question 5: Pharmacology
A school-age child with epilepsy is prescribed oral levetiracetam. The parents report the child has become increasingly irritable and has changes in mood but no recent seizures. What is the nurse’s best response?
- A. “This is expected; no action is needed as long as there are no seizures.”
- B. “Stop the medication and schedule a follow-up visit in a few weeks.”
- C. “Contact the provider to discuss these mood changes and possible dose adjustment.”
- D. “Skip the next few doses to see if the mood changes improve.”
Show Answer & Rationale
Answer: C. “Contact the provider to discuss these mood changes and possible dose adjustment.”
Rationale: The nurse evaluates medication response and teaches parents what to report; behavioral and mood changes are possible adverse effects of antiepileptic drugs and require provider evaluation rather than abrupt discontinuation.
Question 6: Pharmacology
A client with advanced COPD is prescribed home oxygen at 2 L/min via nasal cannula and sustained-release oral morphine for chronic dyspnea. Which instruction is most important for the nurse to reinforce with the client and family?
- A. “Crush the sustained-release morphine tablets if swallowing is difficult.”
- B. “Store the oxygen tank next to the gas stove for easy access.”
- C. “Call the provider if the morphine does not relieve breathlessness.”
- D. “Keep a daily log of bowel movements while taking morphine.”
Show Answer & Rationale
Answer: D. “Keep a daily log of bowel movements while taking morphine.”
Rationale: The nurse provides teaching to reduce medication-related risk; sustained-use opioids frequently cause constipation, so tracking bowel patterns supports early intervention and prevention of complications.
Question 7: Pharmacology
A client with type 2 diabetes and chronic kidney disease is prescribed metformin and recently started IV contrast imaging. Which nursing action is most appropriate regarding metformin therapy?
- A. Encourage taking metformin with contrast to improve glucose control
- B. Hold metformin on the day of the test and for 48 hours afterward as ordered
- C. Increase the metformin dose after the procedure to counteract stress hyperglycemia
- D. Administer metformin immediately after the procedure with extra fluids
Show Answer & Rationale
Answer: B. Hold metformin on the day of the test and for 48 hours afterward as ordered
Rationale: The nurse reviews pertinent data and recognizes high-risk situations; metformin is withheld around iodinated contrast use, especially in clients with kidney disease, to reduce the risk of lactic acidosis.
Question 8: Pharmacology
A client receiving IV gentamicin for a complicated urinary tract infection reports new-onset difficulty hearing and a sense of imbalance. Which action should the nurse take first?
- A. Document the finding as expected with infection
- B. Notify the primary health care provider and hold the next dose
- C. Administer prescribed antiemetic medication
- D. Increase the IV fluid rate to promote drug excretion
Show Answer & Rationale
Answer: B. Notify the primary health care provider and hold the next dose
Rationale: The nurse must recognize signs of toxicity; hearing changes and imbalance suggest ototoxicity from aminoglycosides, so the medication should be held and the provider notified immediately for evaluation and possible dose adjustment.
Question 9: Pharmacology
A client with newly diagnosed major depressive disorder is prescribed sertraline. Which instruction best supports health promotion and safety during the first weeks of therapy?
- A. “You will feel completely better within 24 hours of the first dose.”
- B. “Avoid abruptly stopping this medication, even if you start to feel better.”
- C. “Take extra doses if you feel your mood is not improving quickly enough.”
- D. “Once your mood improves, you can skip doses on days you feel well.”
Show Answer & Rationale
Answer: B. “Avoid abruptly stopping this medication, even if you start to feel better.”
Rationale: The nurse educates about medication self-administration and risk reduction; abrupt discontinuation of SSRIs can cause withdrawal symptoms and relapse, so the medication should be tapered only under provider guidance.
Question 10: Pharmacology
A client with rheumatoid arthritis takes long-term oral prednisone. Which statement by the client indicates a need for additional teaching?
- A. “I will take this medication with food to protect my stomach.”
- B. “I should not stop this medication suddenly; it needs to be tapered.”
- C. “I will avoid live vaccines unless my provider says they are safe.”
- D. “I can skip doses when I feel well because my joints are not inflamed then.”
Show Answer & Rationale
Answer: D. “I can skip doses when I feel well because my joints are not inflamed then.”
Rationale: The nurse educates about chronic corticosteroid therapy; skipping doses on “good days” can cause adrenal insufficiency and loss of disease control, so the client must understand the need for consistent dosing and provider-directed tapering.
