Correct Answer: A

Rationale: In this scenario, the nurse should stand to the side of the patient's eye and observe the cornea. This action is crucial in assessing whether the patient wears contact lenses, especially in unresponsive patients. Observing the cornea can provide valuable information about the patient's eye health and potential use of contact lenses. Choices B, C, and D are incorrect. Concluding that the glasses were lost during the accident is premature without proper assessment. Notifying ambulance personnel about the missing glasses may not be the immediate priority, and asking the unresponsive patient about the glasses would not yield useful information in this situation.

Correct Answer: A

Rationale: The correct answer is to flush the tube before and after each medication administration. This helps prevent clogging and ensures the medication is delivered properly. Mixing medications with enteral feeding (choice B) is incorrect as medications should be administered separately. Pushing tablets through the tube (choice C) is not recommended as they should be properly dissolved before administration. Mixing all crushed medications before dissolving them in water (choice D) is incorrect; medications should be dissolved individually to avoid interactions or inconsistencies in dosages.

Correct Answer: C

Rationale: The correct answer is to recommend the client to use progressive relaxation techniques at bedtime. Progressive relaxation techniques help reduce stress and muscle tension, which can promote better sleep. Choice A, drinking a cup of hot cocoa before bedtime, contains caffeine which can interfere with falling asleep. Choice B, exercising 1 hour before going to bed, can stimulate the body and mind, making it harder to fall asleep. Choice D, reflecting on the day's activities before going to bed, may lead to increased mental activity and prevent relaxation, making it difficult to fall asleep.

Correct Answer: B

Rationale: The correct answer is B: Increased urine output. In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), leading to the excretion of large amounts of dilute urine. Reporting increased urine output is crucial as it is a hallmark sign of diabetes insipidus. Weight gain (choice A) is not typically associated with diabetes insipidus; instead, clients may experience weight loss due to fluid loss. Low blood pressure (choice C) can be a complication of diabetes insipidus due to dehydration from excessive urination, but the priority finding to report is the increased urine output. Thirst (choice D) is a common symptom of diabetes insipidus due to the body's attempt to compensate for fluid loss, but it is not the most critical finding to report.

Correct Answer: A

Rationale: For a client who has undergone an allogeneic stem cell transplant, it is crucial to minimize exposure to potential sources of infection. Wearing a mask when outside the room, especially in areas with construction or other potential risks, helps protect the client's compromised immune system. Positive pressure airflow rooms are typically used for clients with airborne infections, not for those post-stem cell transplant. Restricting all visitors may contribute to the client's well-being, but it is not a direct protective measure against infection. While HEPA filters can be beneficial in maintaining air quality, wearing a mask when exposed to external risks is a more targeted and immediate protective measure in this scenario.
