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 started on long-term therapy with rifampin (Rifadin). A nurse teaches the client that the medication:

• A. Should always be taken with food or antacids
• B. Should be double-dosed if one dose is forgotten
• C. Causes orange discoloration of sweat, tears, urine, and feces
• D. May not be discontinued independently if symptoms are gone in 3 months

Correct answer: C

Rationale: Rifampin causes orange-red discoloration of body secretions, including sweat, tears, urine, and feces. It can also permanently stain soft contact lenses. It is essential to take rifampin exactly as directed and not discontinue it without consulting the healthcare provider.

3. A healthcare professional is planning to administer amlodipine (Norvasc) to a client. The healthcare professional plans to check which of the following before giving the medication?

• A. Respiratory rate
• B. Blood pressure and heart rate
• C. Heart rate and respiratory rate
• D. Level of consciousness and blood pressure

Correct answer: B

Rationale: Before administering amlodipine, it is important to check the client's blood pressure and heart rate. Amlodipine is known to lower blood pressure and heart rate as part of its mechanism of action. Monitoring these vital signs helps ensure the safety of the client and allows for appropriate assessment of the medication's effects post-administration.

4. A client who received a kidney transplant is taking azathioprine (Imuran), and the nurse provides instructions about the medication. Which statement by the client indicates a need for further instructions?

• A. I need to watch for signs of infection.
• B. I need to discontinue the medication after 14 days of use.
• C. I can take the medication with meals to minimize nausea.
• D. I need to call the health care provider (HCP) if more than one dose is missed.

Correct answer: B

Rationale: Azathioprine is an immunosuppressant taken for life. Discontinuing the medication after 14 days is incorrect.

5. The client has been taking omeprazole (Prilosec) for 4 weeks. The ambulatory care nurse evaluates that the client is receiving the optimal intended effect of the medication if the client reports the absence of which symptom?

• A. Diarrhea
• B. Heartburn
• C. Flatulence
• D. Constipation

Correct answer: B

Rationale: Omeprazole, a proton pump inhibitor, is used as an antiulcer agent to reduce gastric acid secretion. The optimal intended effect of omeprazole is the relief of pain and discomfort associated with gastric irritation, commonly referred to as heartburn. Therefore, the absence of heartburn indicates that the medication is working effectively in managing the client's gastric condition.
