Nursing Elites

1. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:

• A. Immediately before swimming
• B. 15 minutes before exposure to the sun
• C. Immediately before exposure to the sun
• D. At least 30 minutes before exposure to the sun

Correct answer: D

Rationale: Chemical sunscreens are most effective when applied at least 30 minutes before exposure to the sun to allow them to penetrate the skin and provide optimal protection. Applying sunscreen immediately before swimming (Choice A) or immediately before exposure to the sun (Choice C) may not provide sufficient time for the sunscreen to be absorbed and offer proper protection. Applying sunscreen 15 minutes before sun exposure (Choice B) is also not ideal as it may not allow enough time for the sunscreen to work effectively. Therefore, the correct answer is to apply chemical sunscreen at least 30 minutes before exposure to the sun to ensure it can be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.

2. A client is being taught about the use of nitroglycerin (Nitrostat) for angina. Which statement by the client indicates a need for further teaching?

• A. I will sit or lie down when I take the medication.
• B. I can take up to three tablets, 5 minutes apart, if needed.
• C. I will call 911 if my chest pain is not relieved after taking three tablets.
• D. I will keep the medication in its original dark container.

Correct answer: B

Rationale: The correct administration of nitroglycerin for angina is to take up to three tablets, 5 minutes apart. If the chest pain persists after the third tablet, emergency medical services should be called. Taking more than three tablets or reducing the time interval between doses may lead to hypotension and indicates a need for further teaching.

3. A client has been prescribed cyclosporine (Sandimmune). Which food item should the client avoid based on the medication's interaction?

• A. Red meats
• B. Orange juice
• C. Grapefruit juice
• D. Green, leafy vegetables

Correct answer: C

Rationale: Grapefruit juice should be avoided when taking cyclosporine because it inhibits the metabolism of the medication, leading to increased blood levels and a higher risk of toxicity. It is important for the client to follow this dietary instruction to ensure the safe and effective use of cyclosporine.

4. A healthcare provider has written a prescription for ranitidine (Zantac), once daily. When should the nurse schedule the medication?

• A. At bedtime
• B. After lunch
• C. With supper
• D. Before breakfast

Correct answer: A

Rationale: The correct answer is A: At bedtime. Ranitidine should be scheduled at bedtime because it provides a prolonged effect and offers the greatest protection of the gastric mucosa. Administering it at this time helps in managing nocturnal acid breakthrough and providing relief during the night.

5. Cycloserine (Seromycin) is added to the medication regimen for a client with tuberculosis. Which of the following would the nurse include in the client-teaching plan regarding this medication?

• A. To take the medication after meals
• B. To return to the clinic weekly for serum drug-level testing
• C. To call the health care provider (HCP) if a skin rash occurs
• D. To restrict alcohol intake with this medication

Correct answer: B

Rationale: Cycloserine requires weekly serum drug level determinations to monitor for neurotoxicity. The medication must be taken after meals, and the client should avoid alcohol. Additionally, the client should report any signs of skin rash or central nervous system toxicity to the healthcare provider.
