Answer to Question 1

ANS: A
Deficiency of antidiuretic hormone (ADH) produces hypothalamic diabetes insipidus, in which large volumes of dilute urine are produced. Head trauma can cause the hypothalamus to stop producing ADH. Diabetes mellitus is an endocrine disorder of the pancreas that causes the production of large volumes of nondilute urine. SIADH is a condition in which too much ADH is produced, causing oliguria. Water intoxication occurs with SIADH.

Answer to Question 2

ANS: D
Propylthiouracil is used for patients experiencing thyroid storm, and this patient is showing signs of that condition. Levothyroxine is given IV for hypothyroidism. 131I is used in patients over age 30 who have not responded to other therapies. Methimazole is used long term to treat hyperthyroidism, but PTU is more useful for emergency treatment.

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.
