Nursing Elites

1. A healthcare professional in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?

• A. Isosorbide
• B. Phenytoin
• C. Metronidazole
• D. Prednisone

Correct answer: A

Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.

2. When teaching a client about preventing Otitis Externa, which of the following instructions should the nurse include?

• A. Clean the ear with a cotton-tipped swab daily.
• B. Place earplugs in the ears when sleeping at night.
• C. Use a cool water irrigation solution to remove earwax.
• D. Tip the head to the side to remove water from the ears after showering.

Correct answer: D

Rationale: To prevent Otitis Externa, the nurse should instruct the client to tip the head to the side to allow water to drain out after showering or swimming. This helps to prevent moisture buildup in the ear canal, reducing the risk of developing Otitis Externa, commonly known as swimmer's ear.

3. When a client is discharged with nitroglycerin (Nitrostat), what should the nurse include in client education?

• A. “Your chest pain should go away with one tablet.”
• B. “If your chest pain doesn’t go away after three tablets, call 911; you might be having a heart attack.”
• C. “If your chest pain doesn’t go away with one tablet, you can repeat the dose as many times as you need to.”
• D. “Be sure to call 911 before you take any tablets.”

Correct answer: B

Rationale: The correct answer instructs the client on the appropriate use of nitroglycerin. Nitroglycerin is used to relieve chest pain or angina. If the chest pain does not subside after taking one tablet, the client should take a maximum of three tablets at 5-minute intervals. If the pain persists after three tablets, it could indicate a heart attack, and emergency medical help should be sought. This education is crucial to ensure the client knows when to seek immediate medical attention.

4. A healthcare provider is planning care for a client with brain cancer experiencing headaches. Which of the following adjuvant medications is indicated for this client?

• A. Dexamethasone
• B. Methylphenidate
• C. Hydroxyzine
• D. Amitriptyline

Correct answer: A

Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer experiencing headaches as it decreases inflammation and swelling. It is commonly used to reduce cerebral edema and relieve pressure caused by the tumor. Methylphenidate (Choice B) is a central nervous system stimulant used in conditions like ADHD and narcolepsy, not for brain cancer headaches. Hydroxyzine (Choice C) is an antihistamine used for anxiety and allergic conditions, not indicated for brain cancer headaches. Amitriptyline (Choice D) is a tricyclic antidepressant used for depression, neuropathic pain, and migraine prophylaxis, but not typically indicated for brain cancer headaches.

5. A client is prescribed Ciprofloxacin and seeks guidance from a nurse. Which instruction should the nurse provide?

• A. Take this medication with meals.
• B. Avoid taking this medication with dairy products.
• C. Take this medication at bedtime.
• D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Avoid taking this medication with dairy products.' Ciprofloxacin should not be taken with dairy products due to the interference of calcium with medication absorption. Taking Ciprofloxacin 1 hour before or 2 hours after consuming dairy products ensures optimal effectiveness. Choice A is incorrect because Ciprofloxacin is usually taken on an empty stomach or with a light meal, not necessarily with heavy meals. Choice C is incorrect as there is no specific instruction to take Ciprofloxacin at bedtime. Choice D is incorrect because there is no need to increase potassium-rich foods intake specifically related to Ciprofloxacin use.
