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 in advance ensures it has enough time to be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.

2. A client with severe acne is seen in the clinic, and the health care provider (HCP) prescribes isotretinoin. The nurse reviews the client's medication record and would contact the HCP if the client is taking which medication?

• A. Vitamin A
• B. Digoxin (Lanoxin)
• C. Furosemide (Lasix)
• D. Phenytoin (Dilantin)

Correct Answer: A

Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the HCP to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects.

3. A client is receiving an intravenous (IV) infusion of an antineoplastic medication. During the infusion, the client complains of pain at the insertion site. The nurse notes redness and swelling at the site, along with a slowed infusion rate. What is the appropriate action for the nurse to take?

• A. Notify the healthcare provider.
• B. Administer pain medication to reduce discomfort.
• C. Apply ice and maintain the infusion rate as prescribed.
• D. Elevate the extremity of the IV site and slow the infusion rate.

Correct Answer: A

Rationale: When a client complains of pain at the IV insertion site, and there are signs of extravasation such as redness and swelling, it is crucial to notify the healthcare provider immediately. Extravasation of antineoplastic medications can cause tissue damage, pain, and necrosis if they escape into surrounding tissues. Prompt action is necessary to prevent further complications and ensure appropriate management of the situation.

4. The clinic nurse is reviewing a teaching plan for a client receiving antineoplastic medication. When implementing the plan, the nurse should advise the client:

• A. To take aspirin (acetylsalicylic acid) as needed for a headache
• B. To avoid drinking beverages containing alcohol
• C. To consult with healthcare providers (HCPs) before receiving immunizations
• D. That it is necessary to consult HCPs before receiving a flu vaccine at the local health fair

Correct Answer: C

Rationale: Antineoplastic medications can lower the body's resistance, making it crucial for clients to consult with healthcare providers (HCPs) before receiving immunizations. This precaution helps to prevent potential complications that may arise due to the medication's impact on the immune system.

5. The client with metastatic breast cancer is receiving tamoxifen. The nurse specifically monitors which laboratory value while the client is taking this medication?

• A. Glucose level
• B. Calcium level
• C. Potassium level
• D. Prothrombin time

Correct Answer: B

Rationale: The correct answer is B: Calcium level. Tamoxifen may increase calcium levels, leading to hypercalcemia. Symptoms of hypercalcemia include increased urine volume, excessive thirst, nausea, vomiting, constipation, muscle weakness, and bone pain. Monitoring serum calcium levels is essential to detect and manage this potential side effect.
