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:

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. 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.

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.

3. A client with chronic renal failure is receiving ferrous sulfate (Feosol). The nurse monitors the client for which common side effect associated with this medication?

Correct answer: D

Rationale: Constipation is a common side effect of iron supplements such as ferrous sulfate. Iron can cause constipation by slowing down the movement of the digestive system and hardening the stool. Patients should be advised to increase their fluid intake, dietary fiber, and physical activity to help alleviate this side effect. Diarrhea (Choice A) is not a common side effect associated with ferrous sulfate. Weakness (Choice B) and headache (Choice C) are not typically linked to this medication.

4. The burn client is receiving treatments of topical mafenide acetate (Sulfamylon) to the site of injury. The nurse monitors the client, knowing that which of the following indicates that a systemic effect has occurred?

Correct answer: A

Rationale: Hyperventilation is an indication of a systemic effect of mafenide acetate (Sulfamylon) due to its potential to cause acidosis by suppressing renal excretion of acid. If hyperventilation occurs, the medication should be discontinued to prevent further complications.

5. The client with breast cancer is receiving cyclophosphamide (Neosar). The nurse is reinforcing medication instructions and advises the client to:

Correct answer: B

Rationale: The correct answer is to increase fluid intake to 2000 to 3000 mL daily. Cyclophosphamide can cause hemorrhagic cystitis as a toxic effect. By increasing fluid intake, the client can help prevent this complication by promoting frequent urination, which reduces the concentration of the drug and its metabolites in the bladder. This dilution effect can help reduce the risk of bladder toxicity.
