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. A client with coronary artery disease complains of substernal chest pain. After checking the client's heart rate and blood pressure, a nurse administers nitroglycerin, 0.4 mg, sublingually. After 5 minutes, the client states, 'My chest still hurts.' Select the appropriate actions that the nurse should take.

Correct answer: B

Rationale: The correct action for the nurse to take in this situation is to contact the registered nurse. When a client with coronary artery disease experiences chest pain and does not achieve relief after the initial administration of nitroglycerin, it is crucial to inform the registered nurse promptly. Following the usual guideline for nitroglycerin administration, the nurse may administer a second tablet after assessing the client's pain level. The nurse should continue to assess the client's pain and monitor vital signs before each dose administration. Calling a code blue is not warranted at this point, as the client's condition does not indicate an immediate life-threatening emergency. Contacting the client's family is not necessary unless requested by the client.

3. A postoperative client has received a dose of naloxone hydrochloride for respiratory depression shortly after transfer to the nursing unit from the postanesthesia care unit. After administration of the medication, the nurse checks the client for:

Correct answer: C

Rationale: Naloxone hydrochloride is an antidote to opioids and may be administered to postoperative clients to address respiratory depression. This medication can also reverse the effects of analgesics, potentially leading to a sudden increase in pain. Therefore, the nurse must assess the client for any unexpected rise in pain levels after naloxone administration. Choices A, B, and D are incorrect because pupillary changes, scattered lung wheezes, and sudden episodes of diarrhea are not typically associated with naloxone administration for respiratory depression.

4. A client taking ethambutol (Myambutol) understands the instructions provided by the nurse if the client states that he or she will immediately report:

Correct answer: B

Rationale: The correct answer is B: Problems with visual acuity. Ethambutol is known to cause optic neuritis, leading to a decrease in visual acuity and color discrimination. Therefore, any visual changes should be reported promptly to prevent further complications. Choices A, C, and D are incorrect because ethambutol does not typically cause impaired sense of hearing, gastrointestinal side effects, or orange-red discoloration of body secretions. It is crucial for clients taking ethambutol to be aware of potential visual disturbances and report them promptly to healthcare providers.

5. A client with diabetes mellitus is prescribed Humulin NPH insulin. The client asks the nurse how to store unopened vials of insulin. The nurse instructs the client to:

Correct answer: B

Rationale: Unopened vials of insulin should be stored in the refrigerator until needed. Freezing insulin can damage it, affecting its efficacy. Storing insulin in a dark, dry place or at room temperature is not recommended as it can lead to degradation of the insulin. Refrigeration helps maintain the stability and effectiveness of insulin.
