1. A client has been prescribed diltiazem (Cardizem) and asks the nurse what type of drug this is. Which response by the nurse is most appropriate?
- A. “A beta blocker.”
- B. “A sodium channel blocker.”
- C. “An alpha blocker.”
- D. “A calcium channel blocker.”
Correct answer: D
Rationale: Diltiazem (Cardizem) belongs to the class of drugs known as calcium channel blockers. These medications work by blocking calcium from entering the muscle cells of the heart and blood vessels, leading to relaxation of the blood vessels and reduced workload on the heart. This helps in lowering blood pressure and improving blood flow. It is crucial for the nurse to provide accurate information to the client about the type of drug prescribed to ensure understanding and compliance with the treatment plan.
2. A client is being educated about the use of Fluticasone to treat Perennial Rhinitis. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should use the spray every 4 hours while I am awake.
- B. It can take as long as 3 weeks before the medication takes maximum effect.
- C. This medication can also be used to treat motion sickness.
- D. I can use this medication when my nasal passages are blocked.
Correct answer: B
Rationale: The correct answer is B because Fluticasone may show some benefits within a few hours, but its full therapeutic effect may take up to 3 weeks to be achieved in treating Perennial Rhinitis. Option A is incorrect as the frequency of Fluticasone use is usually once daily. Option C is incorrect as Fluticasone is not used for motion sickness. Option D is incorrect as Fluticasone is a preventive medication and not used for immediate relief when nasal passages are blocked.
3. During an admission assessment for a client with severe Aspirin toxicity, what finding should the nurse expect?
- A. Body temperature 35°C (95°F)
- B. Lung crackles
- C. Cool, dry skin
- D. Respiratory depression
Correct answer: D
Rationale: In severe Aspirin toxicity, respiratory depression can occur due to increasing respiratory acidosis. Aspirin toxicity leads to metabolic acidosis, stimulating the respiratory center in the brain to increase the respiratory rate initially. However, as the toxicity worsens, respiratory muscle fatigue and depression can occur, resulting in respiratory depression. This can lead to hypoxia, respiratory failure, and ultimately, respiratory arrest.
4. Which of the following is the primary site of activity for the drug Warfarin?
- A. Kidney
- B. Liver
- C. Blood
- D. Heart
Correct answer: B
Rationale: Warfarin primarily affects the liver where it inhibits the synthesis of clotting factors.
5. A client has a prescription for Timolol eye drops for the treatment of glaucoma. Which of the following instructions should the nurse include?
- A. Apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application.
- B. Avoid blinking immediately after instilling the drops.
- C. Keep your eyes closed for 5 minutes after application.
- D. Administer the drops directly onto the cornea.
Correct answer: A
Rationale: The correct instruction for the nurse to include is to apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application. This technique helps prevent systemic absorption of the medication, reducing the risk of systemic side effects. By applying pressure, the drainage of the medication into the bloodstream through the nasolacrimal duct is minimized, enhancing the drug's local ocular effects. Choices B, C, and D are incorrect because blinking immediately after instilling the drops, keeping eyes closed for 5 minutes, and administering the drops directly onto the cornea are not recommended practices for administering Timolol eye drops.
