To begin talking with a newly admitted patient about pain management, the nurse would most appropriately state:

A. Memorizing class notes for tests and studying all night for big tests:

This approach focuses on memorization and last-minute cramming for exams, which doesn't necessarily develop critical thinking skills. It's more about rote learning.
B. Questioning every statement made by instructors to be sure of its correctness:

Questioning and seeking clarification are essential parts of developing critical thinking skills. It's important to question and analyze information critically to ensure its accuracy and relevance.
C. Listening attentively and focusing on the speaker's words and meaning:

Active listening and focusing on understanding the meaning behind what's being said are important aspects of developing critical thinking. It's about comprehending the context and depth of information.
D. Working with an inexperienced nurse:

Working with experienced professionals, even if they're inexperienced nurses, can provide opportunities for real-world problem-solving and critical thinking. In healthcare, learning often occurs through hands-on experience and mentorship.

A. itching:
This is a subjective symptom. Itching is a feeling experienced by the patient and cannot be directly observed by the nurse. The patient's report of itching is subjective until the nurse observes any visible signs of scratching or a rash.

B. headache:
Similar to itching, a headache is a subjective symptom. It is a feeling experienced by the patient and cannot be directly observed by others. The patient's report of a headache is subjective until the nurse observes signs such as the patient holding their head or wincing in pain.

C. rash:
In the given context, a red rash on the face and neck is objective data. Objective data refers to measurable and observable information about a patient's condition. In this case, the nurse can directly observe the rash, making it objective. Objective data is factual and can be verified by others.

D. nausea:
Nausea is also a subjective symptom. It is a feeling experienced by the patient and cannot be directly observed by others. The patient's report of nausea is subjective until the nurse observes signs such as the patient looking pale, sweating, or exhibiting other physical symptoms associated with nausea.
