Safety and side effects 6. Azithromycin dosing requires that the first day’s dosage be twice those of the other 4 days of the prescription. This is considered a loading dose. A loading dose: 1 . Rapidly achieves drug levels in the therapeutic range 2 . Requires four- to five-half-lives to attain 3 . Is influenced by renal function 4 . Is directly related to the drug circulating to the target tissues 7. The point in time on the drug concentration curve that indicates the first sign of a therapeutic effect is the: 1 . Minimum adverse effect level 2 Peak of action . 3 . Onset of action 4 . Therapeutic range 8. Phenytoin requires that a trough level be drawn. Peak and trough levels are done: 1 . When the drug has a wide therapeutic range 2 . When the drug will be administered for a short time only 3 . When there is a high correlation between the dose and saturation of receptor sites 4 . To determine if a drug is in the therapeutic range 9. A laboratory result indicates that the peak level for a drug is above the minimum toxic concentration. This means that the: 1 .

Ralph contacts his NP to discuss the need to increase the dosage. 3. Ralph consistently keeps his follow-up appointments to check his blood pressure. 4. All of the above show that he is adherent to the drug regimen. 7. Nonadherence is especially common in drugs that treat asymptomatic conditions, such as hypertension. One way to reduce the likelihood of nonadherence to these drugs is to prescribe a drug that: 1 . Has a short half-life so that missing one dose has limited effect 2 . Requires several dosage titrations so that missed doses can be replaced with lower doses to keep costs down 3 . Has a tolerability profile with fewer of the adverse effects that are considered “irritating,” such as nausea and dizziness 4 . Must be taken no more than twice a day 8.

Combined with patient education about the need to adhere even when symptoms are absent 11. Many disorders require multiple drugs to treat them. The more complex the drug regimen, the less likely the patient will adhere to it. Which of the following interventions will NOT improve adherence? 1 . Have the patient purchase a pill container with compartments for daily or multiple times-per-day dosing. 2 . Match the clinic appointment to the next time the drug is to be refilled. 3 .

Information Technology and Pharmacotherapeutics Multiple Choice Identify the choice that best completes the statement or answers the question. 1. Being competent in the use of information technology in clinical practice is expected in professional nurses. Advanced practice competence includes the ability to: 1 . Search for information using the most common search engines 2 . Serve as content experts in developing, implementing, and evaluating information systems 3 . Write programs to assure the integrity of health information 4 . Use information technology to prescribe drugs 2. You are going to prescribe a drug and the electronic health record (EHR) alerts you that there is a potential drug–drug interaction. The alert is generated by: 1 . The Food and Drug Administration MedWatch system 2 . TOXNET, the National Institutes of Health alert system 3 . The EHR clinical decision support system 4 . Lexicomp, a commercial medication alert system 3. Which of the following is a primary benefit of the use of computerized provider order entry for patient medications? 1 . Reduces time that prescribing drugs takes 2 . Eliminates the need to chart drugs prescribed 3 . Decreases prescribing and transcription errors 4 . Helps keep the number of drugs prescribed to a minimum 4. A number of barriers and concerns exist before the goals of a safe and efficient information technology (IT) system can be realized. Which of the following is NOT a barrier to adoption and use of IT in prescribing drugs? 1 . Cost of initial setup 2 . Access to highly skilled experts 3 . Compatibility between systems 4 . Patient confidentiality risks 5. EHRs: 1 . Are being discouraged by the Centers for Medicare and Medicaid Services due to cost issues 2 Allow for all patient data to be centralized in one location for access by multiple . 6. Factors that facilitate keeping patient information confidential in an electronic health record (EHR) system include: 1 . Designing software so that only those who need the information can gain access 2 . Requiring providers to log off at the end of the clinical day 3 . Keeping a file of the login and password information for each provider in a secure place 4 . Having patients sign informed consent documents to have their data on an EHR 7. Decision support systems often provide medication alerts that tell the prescriber: 1 . Patient history data with a summary of their diagnoses 2 . The usual dosage for the drug being prescribed 3 . The patient’s latest laboratory values, such as potassium levels 4 . Potential drug-to-drug interactions with other medications the patient is taking 8.
