Answer to Question 1

Answer: 4
Explanation: Lithium can also interfere with sodium and water regulation in the body so it is important that the patient drink plenty of water and avoid overheating. Grapefruit juice does not interact with lithium. Taking lithium with food or milk will reduce possible digestive side effects like nausea, vomiting, diarrhea, and abdominal pain. Some of the other medicines used to treat bipolar disorder, including carbamazepine, interact with birth control pills, but here is no known interaction with lithium.

Answer to Question 2

Answer: 3, 4
Explanation: Two interactions that occur when one substance competes with another at sites of enzymatic activity are of particular importance: induction and inhibition. The inhibitive competition of one substance interferes with the ability of the enzyme to breakdown the other substance, while induction hastens the speed of enzymatic action. Excretion is a pharmokinetic process that is not necessarily associated with drug interactions. Dependence refers to a developed compulsive need to use a substance to function normally. Tolerance results when the presentation of a medication to a receptor leads to a diminished effect of the drug over time.

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.
