1. When teaching a client with a new prescription for Timolol how to insert eye drops, which instruction should the nurse include?
- A. Press your finger on the inside corner of your eye for 1 minute after application.
- B. Apply the eye drops directly on the cornea.
- C. Drop the prescribed amount of medication into the center of the conjunctival sac.
- D. Wipe your eyes gently with a tissue immediately after application.
Correct answer: C
Rationale: The correct way to administer eye drops is by instructing the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps in proper distribution and absorption of the medication. Choice A is incorrect as pressing the inside corner of the eye is not necessary. Choice B is incorrect because applying eye drops directly on the cornea can cause irritation and discomfort. Choice D is incorrect as wiping the eyes immediately after application can remove the medication and reduce its effectiveness.
2. How do ACE inhibitors work?
- A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
- B. Block stimulation of beta 1 and beta 2 at the receptor sites
- C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
- D. None of the above
Correct answer: C
Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
3. A client is starting Simvastatin. Which of the following information should be included in the teaching?
- A. Take this medication in the evening.
- B. Change positions slowly when rising from a chair.
- C. Maintain a steady intake of green leafy vegetables.
- D. Consume no more than 1 L/day of fluid.
Correct answer: A
Rationale: The correct answer is to take simvastatin in the evening. This timing is recommended because nighttime is when the most cholesterol is synthesized in the body. By taking statin medications in the evening, it can enhance their effectiveness in reducing cholesterol levels.
4. A client has a new prescription for rituximab. Which of the following findings should the nurse instruct the client to report?
- A. Dizziness
- B. Fever
- C. Urinary frequency
- D. Dry mouth
Correct answer: B
Rationale: The nurse should instruct the client to report fever. Fever can be an indication of an infection, a potential complication of rituximab therapy. Monitoring and reporting fever promptly can help in early intervention to prevent further complications. Dizziness, urinary frequency, and dry mouth are not typically associated with rituximab therapy and are less likely to be directly related to the medication. Therefore, they are not the priority findings to report in this scenario.
5. A client with brain cancer and headaches is prescribed dexamethasone. What is the purpose of this adjuvant medication?
- A. To decrease inflammation and swelling
- B. To improve concentration
- C. To induce sedation
- D. To treat depression
Correct answer: A
Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer to decrease inflammation and swelling. It helps reduce cerebral edema and relieve pressure caused by the tumor, ultimately alleviating headaches. The purpose of prescribing dexamethasone in this case is not to improve concentration (choice B), induce sedation (choice C), or treat depression (choice D). Methylphenidate, a stimulant, is used for conditions like ADHD, not for brain cancer. Hydroxyzine, an antihistamine, is primarily used for anxiety and itching, not for brain cancer. Amitriptyline, a tricyclic antidepressant, is used for conditions like depression and neuropathic pain, not specifically for brain cancer-related headaches.
