MULTIPLE CHOICE f




1. The nurse is teaching a patient how a medication works to treat an illness. To do this, the
f f f f f f f f f f f f f f f f f


nurse will rely on knowledge of:
f f f f f f


a. clinical pharmacology. f


b. drug efficacy. f


c. pharmacokinetics.
d. pharmacotherapeutics.

ANS: D f


Pharmacotherapeutics is the study of the use of drugs to diagnose, treat, and prevent f f f f f f f f f f f f f


conditions. Clinical pharmacology is concerned with all aspects of drug–human interactions.
f f f f f f f f f f f


Drug efficacy measures the extent to which a given drug causes an intended effect.
f f f f f f f f f f f f f f


Pharmacokinetics is the study of the impact of the body on a drug. f f f f f f f f f f f f

2. What does it mean when a drug is described as easy to administer?
f f f f f f f f f f f f


a. It can be stored indefinitely without need for refrigeration.
f f f f f f f f


b. It does not interact significantly with other medications.
f f f f f f f


c. It enhances patient adherence to the drug regimen.
f f f f f f f


d. It is usually relatively inexpensive to produce.
f f f f f f




ANS: C f


A major benefit of drugs that are easy to administer is that patients taking them are more likely
f f f f f f f f f f f f f f f f f


to comply with the drug regimen. Drugs that are easy to give may have the other attributes
f f f f f f f f f f f f f f f f f


listed, but those properties are independent of ease of administration.

3. A patient tells the nurse that he was told by the prescriber that the analgesic he is taking is
f f f f f f f f f f f f f f f f f f


very effective. Which statement by the patient demonstrates an understanding of the drug’s
f f f f f f f f f f f f f


effectiveness?
f


a. “I don’t have to worry about toxicity, since it takes a large amount of this drug to
f f f f f f f f f f f f f f f f


cause an overdose.”
f f f


b. “It has no side effects and doesn’t interact with other drugs.”
f f f f f f f f f f


c. “I only have to take it every 12 hours.”
f f f f f f f f


d. “It might make me sleepy, and it lessens pain for several hours at a time.”
f f f f f f f f f f f f f f




ANS: D f

, A drug is effective if it produces the intended effects, even if it also produces side effects.
f f f f f f f f f f f f f f f f


Because no drug is completely safe, the level of toxicity does not determine effectiveness. All
f f f f f f f f f f f f f f f


drugs have side effects and many react with other substances; these do not affect the drug’s
f f f f f f f f f f f f f f f f


effectiveness. Ease of administration is independent of a drug’s effectiveness.

ANS: B, C, D f f f


In addition to predictability, ease of administration, and chemical stability, other properties
f f f f f f f f f f f


include a reversible action so that any harm the drug may cause can be undone and a simple
f f f f f f f f f f f f f f f f f f


generic name, because generic names are usually complex and difficult to remember and
f f f f f f f f f f f f f


pronounce.

2. Before administering a medication, what does the nurse need to know to evaluate how
f f f f f f f f f f f f f


individual patient variability might affect the patient’s response to the medication? (Select all
f f f f f f f f f f f f


that apply.)
f f


a. Chemical stability of the medication f f f f


b. Ease of administration f f


c. Family medical history f f


d. Patient’s age f


e. Patient’s diagnosis f




ANS: C, D, E f f f


The family medical history can indicate genetic factors that may affect a patient’s response to a
f f f f f f f f f f f f f f f


medication. Patients of different ages can respond differently to medications. The patient’s
f f f f f f f f f f f f


illness can affect how drugs are metabolized. The chemical stability of the medication and the
f f f f f f f f f f f f f f f


ease of administration are properties of drugs.

MULTIPLE CHOICE f




1. A patient is using a metered-dose inhaler containing albuterol for asthma. The medication
f f f f f f f f f f f f


label instructs the patient to administer “2 puffs every 4 hours as needed for coughing or
f f f f f f f f f f f f f f f f


wheezing.” The patient reports feeling jittery sometimes when taking the medication, and she
f f f f f f f f f f f f


doesn’t feel that the medication is always effective. Which is not an appropriate nursing
f f f f f f f f f f f f f f


intervention for this patient?
f f f f


a. Asking the patient to demonstrate use of the inhaler f f f f f f f f


b. Assessing the patient’s exposure to tobacco smoke f f f f f f


c. Auscultating lung sounds and obtaining vital signs f f f f f f


d. Suggesting that the patient use one puff to reduce side effects f f f f f f f f f f




ANS: D f


It is not within the nurse’s scope of practice to change the dose of a medication without an order
f f f f f f f f f f f f f f f f f f


from a prescriber. Asking the patient to demonstrate inhaler use helps the nurse to
f f f f f f f f f f f f f f


evaluate the patient’s ability to administer the medication properly and is part of the nurse’s
f f f f f f f f f f f f f f


evaluation. Assessing tobacco smoke exposure helps the nurse determine whether nondrug
f f f f f f f f f f f


therapies, such a smoke avoidance, can be used as an adjunct to drug therapy. Performing a physical
f f f f f f f f f f f f f f f f f


assessment helps the nurse evaluate the patient’s response to the medication.

2. A postoperative patient is being discharged home with acetaminophen/hydrocodone (Lortab)
f f f f f f f f f


for pain. The patient asks the nurse about using Tylenol for fever. Which statement by the
f f f f f f f f f f f f f f f f


nurse is correct?
f f f


a. “It is not safe to take over-the-counter drugs with prescription medications.”
f f f f f f f f f f


b. “Taking the two medications together poses a risk of drug toxicity.” f f f f f f f f f f


c. “There are no known drug interactions, so this will be safe.” f f f f f f f f f f


d. “Tylenol and Lortab are different drugs, so there is no risk of overdose.” f f f f f f f f f f f f




ANS: B f


Tylenol is the trade name and acetaminophen is the generic name for the same medication. It is
f f f f f f f f f f f f f f f f


important to teach patients to be aware of the different names for the same drug to minimize the
f f f f f f f f f f f f f f f f f f


risk of overdose. Over-the-counter (OTC) medications and prescription medications may be
f f f f f f f f f f f


taken together unless significant harmful drug interactions are possible. Even though no drug
f f f f f f f f f f f f f


interactions are at play in this case, both drugs contain acetaminophen, which could lead to
f f f f f f f f f f f f f f f


toxicity.

, 3. The nurse is preparing to care for a patient who will be taking an antihypertensive medication.
f f f f f f f f f f f f f f f


Which action by the nurse is part of the assessment step of the nursing process?
f f f f f f f f f f f f f f f


a. Asking the prescriber for an order to monitor serum drug levels f f f f f f f f f f


b. Monitoring the patient for drug interactions after giving the medication f f f f f f f f f


c. Questioning the patient about over-the-counter medications f f f f f


d. Taking the patient’s blood pressure throughout the course of treatment
f f f f f f f f f




ANS: C f


The assessment part of the nursing process involves gathering information before beginning
f f f f f f f f f f f


treatment, and this includes asking about other medications the patient may be taking.
f f f f f f f f f f f f f


Monitoring serum drug levels, watching for drug interactions, and checking vital signs after
f f f f f f f f f f f f


giving the medication are all part of the evaluation phase.

4. A postoperative patient reports pain, which the patient rates as an 8 on a scale from 1 to 10
f f f f f f f f f f f f f f f f f f


(10 being the most extreme pain). The prescriber has ordered acetaminophen (Tylenol) 650
f f f f f f f f f f f f f


mg PO every 6 hours PRN pain. What will the nurse do?
f f f f f f f f f f f f


a. Ask the patient what medications have helped with pain in the past.
f f f f f f f f f f f


b. Contact the provider to request a different analgesic medication. f f f f f f f f


c. Give the pain medication and reposition the patient to promote comfort.
f f f f f f f f f f


d. Request an order to administer the medication every 4 hours. f f f f f f f f f




ANS: B f


The nursing diagnosis for this patient is severe pain. Acetaminophen is given for mild to
f f f f f f f f f f f f f f


moderate pain, so the nurse should ask the prescriber to order a stronger analgesic medication.
f f f f f f f f f f f f f f f


Asking the patient to tell the nurse what has helped in the past is a part of an initial assessment
f f f f f f f f f f f f f f f f f f f f


and should be done preoperatively and not when the patient is having severe pain. Because the
f f f f f f f f f f f f f f f f


patient is having severe pain, acetaminophen combined with nondrug therapies will not be
f f f f f f f f f f f f f


sufficient. Increasing the frequency of the dose of a medication for mild pain will not be
f f f f f f f f f f f f f f f f


effective.

5. A patient newly diagnosed with diabetes is to be discharged from the hospital. The nurse
f f f f f f f f f f f f f f


teaching this patient about home management should begin by doing what?
f f f f f f f f f f f


a. Asking the patient to demonstrate how to measure and administer insulin
f f f f f f f f f f


b. Discussing methods of storing insulin and discarding syringes f f f f f f f


c. Giving information about how diet and exercise affect insulin requirements
f f f f f f f f f
