When performing an otoscope examination for a 2-year-old child, which of the following techniques is correct?

A. Check the client's visual acuity using a Snellen chart: This assesses cranial nerve II (optic), not cranial nerve VII.
B. Observe for facial symmetry while the client smiles: This is the correct method to assess cranial nerve VII (facial nerve), which controls facial muscles, including those responsible for smiling.
C. Have the client identify specific smells: This tests cranial nerve I (olfactory), not cranial nerve VII.

D. Whisper in one of the client's ears while occluding the other: This assesses cranial nerve VIII (vestibulocochlear), not cranial nerve VII.

A. Tenderness in lymph nodes is not necessarily concerning. It may be due to inflammation or infection, which can cause the lymph nodes to be tender as they react to the presence of pathogens. Tenderness alone is not always indicative of a serious condition.
B. A hard lymph node is concerning because it may suggest malignancy or a chronic infection. Hard, firm, and rubbery nodes can be associated with cancers, such as lymphoma or metastasis from other cancers. Therefore, hard lymph nodes should be evaluated further.
C. Lymph nodes up to 1 cm (10 mm) can be considered normal, depending on the location and individual characteristics of the patient. A 4 mm lymph node is typically not concerning, especially if it is non- tender and mobile. Larger nodes, especially those over 1 cm, are more concerning.
D. Lymph nodes that are immovable or fixed to surrounding tissues are concerning and may suggest malignancy. Cancerous nodes tend to be harder, larger, and fixed in place, which makes them less mobile. Any immovable lymph node requires further investigation.
E. Non-palpable lymph nodes are normal and generally not a concern. Lymph nodes that are not palpable typically do not signify a problem, as they may be too small to be felt or located deep within the tissues.
