1. A client has been prescribed Aspirin for prevention of cardiovascular disease. Which of the following findings indicates the medication is effective?
- A. The client has a decrease in troponin levels.
- B. The client has a regular heart rhythm.
- C. The client experiences a decrease in episodes of angina.
- D. The client's blood pressure remains stable.
Correct answer: C
Rationale: The correct answer is C. A decrease in episodes of angina is an indicator of Aspirin's effectiveness in preventing cardiovascular events. Aspirin works by inhibiting platelet aggregation, thereby reducing the formation of blood clots that could lead to angina episodes or more severe cardiovascular complications. Choices A, B, and D are incorrect because troponin levels, heart rhythm, and blood pressure are not direct indicators of Aspirin's effectiveness in preventing cardiovascular events.
2. 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.
3. A client has been prescribed Nitroglycerin patches for angina. Which of the following instructions should the nurse include during discharge teaching?
- A. Apply the patch to a different site each time.
- B. Remove the patch for 12 hours each day.
- C. Apply the patch at the same time every day.
- D. Cut the patch in half if your blood pressure is well controlled.
Correct answer: B
Rationale: The correct answer is B: 'Remove the patch for 12 hours each day.' Nitroglycerin patches should be removed for 12 hours each day to prevent the development of tolerance. This nitrate-free interval ensures the medication remains effective in managing angina. Choice A is incorrect because applying the patch to a different site each time is not necessary; it is more important to ensure a nitrate-free interval. Choice C is incorrect because while consistency in timing is good for medication adherence, the crucial aspect for Nitroglycerin patches is the nitrate-free interval. Choice D is incorrect because cutting the patch in half based on blood pressure control is not a recommended practice and could alter the medication's efficacy.
4. Phenytoin is an antiarrhythmic and anticonvulsant that has an unlabeled use for:
- A. Headaches
- B. Cold remedy
- C. Neuropathic pain
- D. Antianxiety
Correct answer: C
Rationale: Phenytoin, an antiarrhythmic and anticonvulsant medication, is also used off-label for treating neuropathic pain. While its primary indications are for managing heart rhythm disorders and seizures, it has shown efficacy in managing neuropathic pain, expanding its clinical utility. Choices A, B, and D are incorrect as phenytoin is not commonly used for headaches, cold remedies, or antianxiety purposes.
5. When administering the drug senna to a patient, what must a health care provider inform the patient of?
- A. This drug is intended to lower blood pressure and is best used in combination with other antihypertensives
- B. This drug is not intended for long-term use
- C. The patient must limit his/her fiber intake
- D. Advise the patient to change positions slowly to limit the risk of orthostatic hypotension
Correct answer: B
Rationale: The correct answer is B. Senna is a laxative used for short-term relief of constipation, not for long-term use. Choice A is incorrect because senna does not lower blood pressure or require combination with antihypertensives. Choice C is unrelated as there is no need to limit fiber intake with senna. Choice D is incorrect as orthostatic hypotension is not a common concern with senna use.
