The nurse examines a patient who has asthma and chronic hypoxemia. The nurse would expect to find which condition of the nails?

Choice A reason: Guidelines recommend the first Pap smear at age 21, regardless of sexual activity, to screen for cervical cancer. This age balances the risk of detecting clinically significant abnormalities while avoiding unnecessary testing in younger women, whose HPV infections often resolve.

Choice B reason: Age 16 is too early for routine Pap smears, as cervical cancer is rare in adolescents, and HPV infections often clear spontaneously. Screening at this age may lead to overdiagnosis and unnecessary procedures, making it an incorrect recommendation.

Choice C reason: Tying Pap smears to sexual activity is outdated. Current guidelines recommend starting at age 21, as earlier screening in sexually active younger women often detects transient HPV infections, leading to overtreatment, making this an incorrect criterion.

Choice D reason: Age 18 is not the recommended starting point for Pap smears, as cervical cancer risk is low in this age group, and screening may lead to unnecessary interventions. Guidelines specify age 21 for routine screening, making this choice incorrect.

Choice A reason: Cranial Nerve VII (facial nerve) controls facial expression muscles. Asking the patient to smile tests the nerve’s motor function, specifically the zygomaticus muscles, which elevate the mouth corners, making this a correct assessment task for this nerve.

Choice B reason: Closing eyes tightly assesses Cranial Nerve VII’s motor function, specifically the orbicularis oculi muscle, which closes the eyelids. Weakness or asymmetry indicates potential facial nerve dysfunction, making this a correct task for evaluating this nerve.

Choice C reason: Shrugging shoulders tests Cranial Nerve XI (spinal accessory nerve), which innervates the trapezius and sternocleidomastoid muscles. This action is unrelated to Cranial Nerve VII’s facial motor functions, making it an incorrect choice for this assessment.

Choice D reason: Frowning assesses Cranial Nerve VII’s control over the corrugator supercilii and procerus muscles, which wrinkle the brow and depress the mouth. This task evaluates facial nerve function, making it a correct choice for the assessment.

Choice E reason: Smelling a flower tests Cranial Nerve I (olfactory nerve), responsible for smell sensation. This is unrelated to Cranial Nerve VII’s motor functions for facial expressions, making it an incorrect task for assessing this nerve.
