  D) Improving concentration in the body

Question 2

The nurse is caring for an adolescent patient who began taking an antipsychotic drug last month to treat newly diagnosed schizophrenia.
 
  The drug has not been effective and the mother asks the nurse if this means the adolescent's symptoms cannot be controlled by drugs. What is the nurse's best response? A) Patients commonly have to try different drugs until the most effective drug is identified.

  C) Most likely your child was not taking the medication properly as prescribed.

Answer to Question 1

A
Feedback:
This specificity allows the clinician to select a drug that will have the desired therapeutic effects without the undesired effects that occur when the entire sympathetic nervous system is blocked. In general, however, the specificity of adrenergic blocking agents depends on the concentration of drug in the body. Most specificity is lost with higher serum drug levels.

Answer to Question 2

A
Feedback:
A patient who does not respond to one drug may react successfully to another agent. Responses may also vary because of cultural issues. The selection of a specific drug depends on the desired potency and patient tolerance of the associated adverse effects. It is not common to have a patient who does not demonstrate some improvement from medications so it would be incorrect to tell the mother the child won't respond to any drug after trying only one medication. There is no indication the drug was taken improperly and even properly administered drugs will not work on all patients. Multiple drug therapy is not indicated by the question.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
