Sample Questions Are Posted Below
| 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. | ||
