What is the typical range for normal pupil size in adults under normal lighting conditions?

Rationale:
A. SBAR is not primarily used for documenting patient care plans. While documentation is an important aspect of nursing practice, SBAR is specifically designed as a communication framework rather than a documentation tool. Therefore, this option is incorrect.

B. SBAR (Situation, Background, Assessment, Recommendation) is a standardized communication tool used to ensure clear, concise, and organized exchange of critical patient information, especially during handoffs and urgent situations. It reduces miscommunication, promotes clarity, and improves patient safety. This is the correct answer because it reflects the primary purpose of SBAR in clinical practice.

C. SBAR is not intended to facilitate electronic medical record (EMR) entry. Although it may indirectly support organized thinking that could help with documentation, its main role is verbal and written communication between healthcare providers, not EMR processing. This option is incorrect.

D. While SBAR may support adherence to hospital policies by promoting effective communication, its primary purpose is not policy compliance. Instead, it is focused on improving communication efficiency and patient safety. Therefore, this option is incorrect.

Rationale:

A. Lymph nodes that are freely moveable under the skin are typically normal. Mobility indicates that the node is not infiltrated by fibrotic tissue or malignant cells. Moveable nodes may shift slightly during palpation and are usually soft or rubbery.

B. Smooth lymph nodes are generally normal. Irregular, nodular, or spiculated nodes are more concerning for pathology. Smoothness alone does not indicate abnormality.

C. Non-tender lymph nodes are often normal, particularly if they are small and soft. Tenderness is usually associated with acute infections, such as localized cellulitis or mastitis. Therefore, non-tender nodes in isolation are not considered abnormal.

D. Hard lymph nodes are abnormal. Hardness suggests that the node may be infiltrated with malignant cells or fibrotic tissue, which can occur in breast cancer metastasis or chronic infections. Hard nodes are less compressible and may be associated with an irregular surface.

E. Fixed, immobile lymph nodes are also abnormal. Normal nodes are freely movable; when nodes are adherent to surrounding tissues, it can indicate malignancy, fibrosis, or metastatic spread. Fixed nodes do not shift easily with palpation and require prompt medical evaluation.
