Nursing Elites

1. 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.

2. A client has a new prescription for spironolactone. The nurse should instruct the client to avoid which of the following foods?

• A. Salt substitutes
• B. Apples
• C. Chicken
• D. Bananas

Correct answer: A

Rationale: Spironolactone is a potassium-sparing diuretic. The client should avoid salt substitutes because they often contain potassium, which could lead to hyperkalemia. Hyperkalemia, or high levels of potassium in the blood, is a potential side effect of spironolactone, and ingesting additional potassium from salt substitutes can exacerbate this risk.

3. 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.

4. A client receiving chemotherapy reports nausea and vomiting. Which of the following medications should the nurse anticipate administering?

• A. Ondansetron
• B. Metoclopramide
• C. Promethazine
• D. Lorazepam

Correct answer: A

Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.

5. A client has a new diagnosis of Fibromyalgia. Which of the following medications should the nurse anticipate being prescribed for this client?

• A. Colchicine
• B. Hydroxychloroquine
• C. Auranofin
• D. Duloxetine

Correct answer: D

Rationale: The correct answer is D, Duloxetine. Duloxetine is a serotonin-norepinephrine reuptake inhibitor commonly used to manage fibromyalgia. It helps in reducing pain and improving mood in individuals with this condition. Colchicine (Choice A) is primarily used to treat gout, while Hydroxychloroquine (Choice B) and Auranofin (Choice C) are medications used to manage conditions like rheumatoid arthritis and lupus, not fibromyalgia.
