Answer to Question 1

A

Feedback
A The ileum is the longest part of the small intestine.
B The jejunum measures about 2.7 m.
C The duodenum measures about 22 cm.
D The descending colon is not part of the small intestine; it is part of the large intestine.

Answer to Question 2

B

Feedback
A The therapeutic effect is the expected or predictable physiological response a medication causes. Respiratory depression and decreased urine output are not the desired (i.e., therapeutic) effects of morphine.
B Toxic levels of morphine may cause severe respiratory depression. Toxic effects may develop after prolonged intake of a medication or when a medication accumulates in the blood because of impaired metabolism or excretion. The patient with a decreased urine output is not excreting the morphine.
C An idiosyncratic effect occurs when a medication causes an unpredictable outcome, such as when a patient overreacts or underreacts to a medication. This is not an example of an idiosyncratic effect.
D When a patient experiences an allergic response to a medication, the medication acts as an antigen, triggering the release of antibodies. The patient may experience itching, urticaria, a rash, or in more severe cases, may have difficulty breathing. This patient's response to morphine is not an example of an allergic effect.
