Answer to Question 1

ANS: B
It would be unusual for pruritus in the head and neck to indicate anything except a skin condition/disease or infestation. If the patient is a school-age child, pediculosis (head lice) is an obvious choice, and the child's friends and school administrators should be questioned about recent outbreaks. Nits are lice eggs that are fixed to the hair shaft and are grayish-white in appearance. Unlike the flakiness of seborrhea or psoriasis, nits cannot be easily dislodged. Basal cell carcinoma is a slow-growing, invasive type of skin cancer that occurs on sun-exposed regions of the head, such as the nose.

Answer to Question 2

ANS: D
Hyperthyroidism does not necessarily coincide with a thyroid nodule. Myxedema is a tissue swelling of the face and body due to hypothyroidism. Trigeminal neuralgia causes paroxysms of pain on one side of the face. Thyroid cancer presents as a solitary cold nodule on a thyroid ultrasound. Predisposing factors include female gender, positive family history, and history of radiation exposure to the head, face, or neck.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
