NURS 6521 WEEK 2 QUIZ

A patient has taken an overdose of a vitamin/mineral supplement containing magnesium. The nurse will be sure to assess 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. 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? A nurse receives an order to administer a critically ill patient two drugs immediately (stat). The nurse begins the process by Response A nurse should always make sure that two or more drugs can be given Feedback: 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. A 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. A physician has ordered subcutaneous injections of morphine, a narcotic, every 4 hours as needed for pain for a motor vehicle accident victim. The nurse is aware that there is a high abuse potential for this drug and that it is categorized as a Response Feedback: Narcotics such as morphine are considered C-II drugs because of the high abuse potential with severe dependence liability. C-I drugs have high abuse potential and are not accepted for medical use. C-III drugs have a lesser abuse potential than C-II drugs and an accepted medical use. C-IV drugs have a low abuse potential and limited dependence liability. 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 The patient would likely be prescribed a lower-than-normal dose of Feedback: 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. What critical piece of information is missing from the following medication order: Amoxicillin 250 mg every 8 hours? 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. 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.
