Question 1
1 out of 1 points
A
... [Show More] nurse working for a drug company is involved in phase III drug evaluation studies. Which of the following might the nurse be responsible for during this stage of drug development?
Response Feedback:
Phase III studies involve administering investigational drugs to patients in a vast clinical market who are voluntarily enrolled in double-blind studies. In phase I studies, a small number of healthy human volunteers are given the drug after blood urine and other appropriate samples are taken to monitor drug metabolism. Sometimes volunteers who have a certain disease are used in phase I instead of healthy volunteers if the drug is expected to have significant toxicity. In phase II, volunteers are given various dosages of the test compound and studied in great detail. Dosage guidelines are usually determined in this phase. Nurses are more likely to be responsible for administering the investigational drugs in phase III than in phases I and II. Use of animal testing is done in the preclinical trials and would not involve a nurse.
Question 2
A nurse is a member of a research team that is exploring unique differences in responses to drugs that each individual possesses, based on genetic make-up. This area of study is called

:
Pharmacogenomics is the area of study that explores the unique individual patient responses to drugs based on the mapping of the human genome. This mapping introduces the possibility of personally designed medical care and drug regimens based on a person's unique genetic make-up.
Pharmacotherapeutics is the branch of pharmacology that deals with uses of drugs to treat, prevent, and diagnose disease. Pharmacodynamics involves how a drug affects the body, and pharmacoeconomics includes any costs involved in drug therapy.
Question 3
The nurse practitioner orders Amoxicillin 250 mg/5 ml tid for 10 days? The nurse

practitioner would expect the pharmacist to fill the prescription bottle with how many ml?
Question 4
A nurse works in a private hospital and needs to administer some narcotic drugs to one of her patients. Which of the following should the nurse consider when administering narcotics to patients in a hospital setting?
1 out of 1 points
Response Feedback:
A nurse can administer narcotics in the hospital after ensuring that narcotics are dispensed only with a written prescription. JCAHO sets the standards for quality of patient care and accreditation of health care institutions, not for using narcotics.
Question 5
1 out of 1 points
A patient has been prescribed a drug that can be self-administered at home. Which of
the following would be the most important information for the nurse to relate to the patient concerning self-administration of a drug?
Response Feedback:
The patient must be knowledgeable about all aspects of the drug regimen so it can be self-administered safely and effectively. All of the responses are important, but the patient must be able to tell if the drug is producing an effective response and must also know the adverse effects to report.
Knowing where to purchase the medication and how much it costs is good information, but it is not the most important information for self- administration. Knowing the pharmacokinetics does not concern most patients.
Question 6
A patient with seasonal allergies is exasperated by her recent nasal congestion and has expressed her desire to treat it by using pseudoephedrine. The nurse should inform the patient that
1 out of 1 points
Response Feedback:
Sudafed and any combination drugs that contain pseudoephedrine have been removed from the shelves of drug stores, but they have not been taken off the market. Consumers must purchase drugs containing pseudoephedrine from a pharmacy, despite the fact the drugs do not require a prescription. Identification is not required to purchase these drugs.
Question 7
1 out of 1 points
A nurse has just completed a medication history on a newly admitted patient. In order to complete medication reconciliation for this patient the nurse will
Response Feedback:
The process of comparing medications ordered by the health care provider with the medications the patient is taking at home and communicating the discrepancies is called medication reconciliation. This process is continued each time the patient is transferred within the hospital, and at discharge. At discharge when the drug regimen is set, the nurse will educate the patient and the family about the medications. This process improves patient outcomes, hopefully preventing serious effects. Determining where the patient buys his medication is not usually done by the hospital nurse.
Patients do not need to know the pharmacokinetics of each drug they take unless they ask.
Question 8
1 out of 1 points
A nurse receives an order to administer a critically ill patient two drugs immediately (stat). The nurse begins the process by
Response Feedback:
A nurse should always make sure that two or more drugs can be given at the same time before the administration process is begun. Incompatibility can affect absorption and distribution. Once the nurse is certain that the drugs are compatible, he or she should perform handwashing and prepare the medications for administration. The nurse should also identify the patient appropriately and ask about drug allergies prior to administering the medication.
Question 9
1 out of 1 points
A patient comes to primary clinic for strep throat. A throat swab culture is sent to lab. What information is required for the nurse practitioner to disclose on lab transmittal?
Question 10
A nurse is providing a patient with a list of drugs as a part of the patient's plan of care. Which of the following drug nomenclatures should the nurse use to list the drugs?
Response Feedback:
The nurse should ideally use the generic names of the drugs in care plans. The generic name is also known as its nonproprietary name. Usually, a drug is ordered by the generic name because numerous trade names may exist for the same drug. It is difficult to remember a drug by its chemical name, because it is usually long and complex. Therefore, drugs are generally not known by their chemical names. Drugs do not have biologic names.
Question 11
A nurse is providing care for a 71-year-old woman who was sponsored to emigrate from Mexico to the United States 6 months ago. Earlier this week, the woman slipped while getting off a bus and fractured her hip. How should the woman's nurse best exemplify cultural competence in the care of this patient?
Response Feedback:
Cultural competence requires maintaining awareness of one's own values and beliefs without letting them have undue influence on those of other backgrounds, demonstrating knowledge and understanding of another's culture, accepting and respecting cultural differences, and considering a patient's culture carefully. This does not mean that only Spanish-speaking staff members should provide care, that the nurse must teach the patient about American culture or that the nurse should address the children before the patient.
Question 12
A patient has taken an overdose of a vitamin/mineral supplement containing magnesium. The nurse will be sure to assess
1 out of 1 points
Response Feedback:
An increase of magnesium could cause hypotension; therefore, the nurse should assess the patient's blood pressure. Body temperature, skin changes, and fluid intake are not critically associated with an overdose of magnesium.
Question 13
Which of the following patients should be advised by the nurse to avoid over-the- counter cold and allergy preparations that contain phenylephrine?
1 out of 1 points
Response Feedback:
Phenylephrine is an alpha-1 adrenergic agonist and a drug commonly used topically for relief of nasal and nasopharyngeal mucosal congestion and to produce mydriasis for ophthalmologic procedures. Phenylephrine acts as a vasopressor causing vasoconstriction of the arterioles. The vasoconstriction from phenylephrine use can increase peripheral resistance and blood pressure. People with hypertension should not take over-the-counter cold and allergy preparations containing phenylephrine because it can further increase their already elevated blood pressure. Patients with diabetes and
gout have not been identified as being at risk for adverse reactions from the use of phenylephrine. A patient with an upper respiratory infection may actually benefit from use of the drug.
Question 14
A nurse at a large, university hospital has been informed that a drug trial will be taking place that may involve several patients in the hospital over the next several months. What is the nurse's most likely role in this drug testing process?
1 out of 1 points
Response Feedback:
Nurses are generally most involved in phase III of clinical trials and may be responsible for administering investigational drugs to patients. The final determination of the efficacy and safety of the drug is beyond the scope of nurses. Nurses do not normally consult on the choice of testing methodology.
Question 15
A patient will begin three new medications as part of her treatment plan. The nurse practitioner understands that proper disposal of medications is key when the nurse practitioner states
Question 16
The nurse practitioner orders Amoxicillin 500 mg tid? What is the total amount of medication patient will take per day?
Question 17
These drugs have a potential for abuse, but the potential is lower than for drugs on Schedule 2. These drugs contain a combination of controlled and noncontrolled

substances. Use of these drugs can cause a moderate to low physiologic dependence and a higher psychological dependence. A verbal order can be given to the pharmacy and the prescription can be refilled up to five times within 6 months. Examples include certain narcotics (codeine) and nonbarbiturate sedatives. This is scheduled drug
Question 18
1 out of 1 points
Drugs have a valid medical use but a high potential for abuse, both psychological and physiologic. In an emergency, a Schedule 2 drug may be prescribed by telephone if a written prescription cannot be provided at the time. However, a written prescription must be provided within 72 hours with the words authorization for emergency dispensing written on the prescription. These prescriptions cannot be refilled. A new prescription must be written each time. Examples include certain amphetamines and barbiturates. This is scheduled drug
Question 19
A patient has been prescribed a Scheduled 5 drug, an example of this drug is
Question 20

A 46-year-old white American has been prescribed a drug that binds to acid glycoproteins. The nurse understands that white Americans usually receive
Response Feedback:
White Americans have been found to have more acid glycoproteins than other ethnic groups. Therefore, when they take drugs that bind to these proteins, they have lower amounts of free or active drug than when the same dose is given to someone of another ethnic group. Since the patient is a white American, he has been prescribed a higher-than-normal dose of the drug that binds to the acid glycoprotein.
Question 21
A nurse is admitting a Mexican woman to the hospital who cannot speak or

understand English. The patient is alone, and there is no interpreter available. When trying to communicate with the patient the nurse will
Response Feedback:
If an interpreter or translator is not available, the nurse should look at the patient, speak slowly, and use nonverbal communication to help the patient understand the message. Speaking loudly and using exaggerated mouth movements only serve to intimidate or belittle the patient and should not be done.
Question 22
What critical piece of information is missing from the following medication order: Amoxicillin 250 mg every 8 hours?
Question 23
Drugs have a high potential for abuse. There is no routine therapeutic use for these drugs and they are not available for regular use. They may be obtained for

“investigational use only” by applying to the U.S. Drug Enforcement Agency. Examples include heroin and LSD. Which scheduled drug is this?
Question 24
A Native American man who lives a traditional lifestyle is scheduled to have heart

surgery. The tribal chief has requested that the tribe's medicine man perform a ritual before the patient goes to surgery. The nurse's response to this request should be
Response Feedback:
If possible, every effort should be made to accommodate the patient's traditional practices. As long as the rituals or ceremonies do not interfere with treatment or care, they should be allowed. The nurse does not have to notify the physician if the patient's care is uninterrupted. A nurse should never be judgmental or make light of cultural practices.
Question 25

A nurse is caring for a 46-year-old patient of Chinese origin who has bipolar disorder. The physician has prescribed lithium carbonate (Eskalith) to treat the disorder. The nurse is aware that the lithium dose will likely be given in a
Response Feedback:
The patient would likely be prescribed a lower-than-normal dose of lithium to treat the disorder since he is an American. Chinese Americans require
lower levels of lithium to achieve a therapeutic response. Different drugs can be metabolized only by specific liver enzymes, and receptors are custom-designed to accept only certain drug configurations. As with enzymes, the number and type of receptors are influenced by genetics. Chinese Americans, and other Chinese people, appear to have a greater number of lithium-activated receptors than other groups. [Show Less]
