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 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.

3. Rifabutin (Mycobutin) is prescribed for a client with active Mycobacterium avium complex (MAC) disease and tuberculosis. The nurse monitors for which side effects of the medication? Select one that doesn't apply.

• A. Signs of hepatitis
• B. Flu-like syndrome
• C. Low neutrophil count
• D. Vitamin B6 deficiency

Correct answer: D

Rationale: Rifabutin is known to cause side effects such as hepatitis, flu-like syndrome, low neutrophil count, and ocular pain or blurred vision. Vitamin B6 deficiency is not associated with rifabutin but is a side effect of isoniazid (INH). Therefore, the nurse should not monitor for Vitamin B6 deficiency when administering rifabutin.

4. 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.

5. A client is being monitored while receiving bethanechol chloride (Urecholine) for urinary retention. Which of the following indicates a therapeutic effect of this medication?

• A. Increased heart rate
• B. Increased peristalsis
• C. Passage of flatus
• D. Urinary output of 50 mL per hour

Correct answer: D

Rationale: Bethanechol chloride (Urecholine) is administered to stimulate the bladder and treat urinary retention. The therapeutic effect is indicated by an increased urinary output, as it demonstrates the medication's ability to prompt the bladder to empty. Increased heart rate and passage of flatus are unrelated to the therapeutic effects of bethanechol. Although bethanechol can increase peristalsis, the primary therapeutic goal is to address urinary retention.
