Correct Answer: D

Rationale: The correct answer is D because using the index and middle fingers to palpate with gentle pressure in a rotating pattern allows for a thorough examination of the lymph nodes without causing discomfort or injury. This method helps to assess the size, shape, consistency, and tenderness of the nodes accurately. It also enables the examiner to detect any abnormalities such as enlargement or tenderness. A is incorrect as using strong pressure can be painful and lead to inaccurate assessment. B is incorrect as strong pressure can be harmful and may not provide the necessary sensitivity to detect abnormalities. C is incorrect as pinching each node can be uncomfortable and may not allow for a systematic examination of the lymph nodes.

Correct Answer: D

Rationale: The correct answer is D. The "soft spot" on a baby's head, also known as the fontanelle, is a normal anatomical feature that allows for the growth and development of the baby's brain during the first year of life. It is a gap between the bones of the skull that eventually closes as the baby grows. Response A is incorrect because the fontanelle is not related to maternal dietary intake during pregnancy. Response B is incorrect as craniosynostosis is a condition where the sutures of the skull close prematurely, leading to abnormal head shape. Response C is incorrect as cretinism and congenital hypothyroidism are not typically associated with the fontanelle. Overall, the correct response, D, provides an accurate explanation of the normal function of the fontanelle in a newborn's development.

Correct Answer: B

Rationale: The correct answer is B because unequal pupillary constriction in response to light is abnormal and may indicate nerve damage or neurological issues. A: Decrease in tear production is common with age. C: Arcus senilis is a normal age-related change. D: Loss of hair at the outer line of the eyebrows is also a common age-related change.

Correct Answer: C

Rationale: The correct answer is C: Degeneration of nerves in the inner ear. This is likely the cause of the patient's hearing difficulties, as age-related degeneration of nerves in the inner ear can lead to difficulty distinguishing sounds and determining their direction. Atrophy of the apocrine glands (Choice A) and cilia becoming coarse and stiff (Choice B) are not related to hearing loss. Scarring of the tympanic membrane (Choice D) would affect sound conduction but not the perception of sound direction and clarity.

Correct Answer: B

Rationale: The correct answer is B (XI; asking the patient to shrug her shoulders against resistance). This is the correct choice because the nurse suspects damage to the spinal accessory nerve (CN XI), which innervates the trapezius and sternocleidomastoid muscles. Asking the patient to shrug her shoulders against resistance tests the function of the trapezius muscle, which is innervated by CN XI. This examination helps to assess the integrity of the nerve and its ability to innervate the muscle. Palpating the anterior and posterior triangles (choice A) is not specific to CN XI function. Percussing the sternomastoid and submandibular neck muscles (choice C) is related to CN XII, not CN XI. Assessing for a positive Romberg's sign (choice D) is not relevant to testing the function of CN XI.
