1. Which cellular structure stores hormones and other substances and packages these
substances into secretory granules?
A) Golgi apparatus
B)
... [Show More] Endoplasmic reticulum
C) Mitochondria
D) Lysosome
Ans: A
Feedback:
The golgi apparatus stores hormones and other substances. The endoplasmic reticulum
contains ribosomes, which synthesize proteins, including enzymes that synthesize
glycogen, triglycerides, and steroids and those that metabolize drugs and other
chemicals. The mitochondria generate energy for cellular activities and require oxygen.
Lysosomes are membrane-enclosed vesicles that contain enzymes capable of digesting
nutrients (proteins, carbohydrates, fats), damaged cellular structures, foreign substances
(bacteria), and the cell itself.
2. A patient is suffering from a cough associated with an upper respiratory infection.
Which oral medication will likely produce the most therapeutic effect?
A) A tablet
B) An expectorant
C) A topical spray
D) A timed-release tablet
Ans: B
Feedback:
Liquid medications are absorbed faster than tablets or capsules. Expectorants are liquid
medications. A tablet is an oral medication that has a slower onset of action than a liquid
medication. A topical spray can be sprayed to the back of the throat and provides only a
local effect. A timed-release tablet is an oral medication that has a slower onset and
longer duration of action.
3. A patient is administered an oral contraceptive. Which of the following is the process
that occurs between the time the drug enters the body and the time that it enters the
bloodstream?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Ans: A
Feedback:
Absorption is the process that occurs from the time the drug enters the body to the time
it enters the bloodstream to be circulated. Distribution involves the transport of drug
molecules within the body. Metabolism is the method by which drugs are inactivated or
biotransformed by the body. Excretion refers to elimination of a drug from the body [Show Less]
