1. Which cellular structure stores hormones and other substances and packages these
substances into secretory granules?
A) Golgi apparatus
B) 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.

, 4. Which of the following sites of drug absorption is considered to have an exceptionally
large surface area for drug absorption?
A) Rectum
B) Fundus of the stomach
C) Esophagus
D) Lungs
Ans: D
Feedback:
The lungs have a large surface area for absorption of anesthetic gases and a few other
drugs. The rectum absorbs the medication through the mucous membranes and has a
smaller surface area than the lungs. The fundus and esophagus have comparatively
small surface areas.
5. A nurse is aware of the importance of adhering to the intended route of a medication.
Which of the following drugs are formulated to be absorbed through the skin?
A) Amoxicillin, tetracycline, and penicillin
B) Clonidine, fentanyl, and nitroglycerin
C) Digoxin, lidocaine, and propranolol
D) Insulin, heparin, and morphine
Ans: B
Feedback:
Some drugs are formulated in adhesive skin patches for absorption through the skin.
Clonidine, fentanyl, and nitroglycerin are examples of drugs that are formulated in
adhesive skin patch form to be absorbed through the skin. Amoxicillin, tetracycline, and
penicillin are administered orally. Digoxin and propranolol are administered orally, and
lidocaine can be administered intravenously, subcutaneously, or topically. Insulin and
heparin are administered intravenously and subcutaneously. Morphine is administered
orally, intramuscularly, and intravenously.
6. An 85-year-old patient has an elevated serum creatinine level, indicating impaired
kidney function. When the patient is administered a medication, this patient is at risk for
which of the following medication-related effects?
A) Toxicity
B) Increased absorption
C) Delayed gastric emptying
D) Idiosyncratic effects
Ans: A
Feedback:
An elevated creatinine level is indicative of diminished kidney function, which will
result in serum drug toxicity. The creatinine level indicates kidney function, does not
affect absorption, and has no effect on gastric emptying.
