Question 16 1 out of 1 points Which of the following statements best defines how a chemical becomes termed a drug? Response Feedback : Even though all the responses are correct, a chemical must undergo a series of tests to determine its therapeutic value and efficacy without severe toxicity or damaging properties before it is termed a drug. Test results are reported to the FDA, which may or may not give approval. Question 17 1 out of 1 points An elderly postsurgical patient has developed postoperative pneumonia in the days following abdominal surgery and is being treated with a number of medications. Which of the following medications that the nurse will administer has the slowest
absorption? Response Feedback: Absorption of drugs is dependent primarily on the route of administration. IV, IM, and sublingual administration results in faster absorption than drugs that are given orally. Question 18 1 out of 1 points An unconscious patient has been brought to the hospital, and the physician has prescribed a life-saving drug to be administered parenterally. Which of the following methods would be the most appropriate for the nurse to use when administering the medication? Response Feedback : Intravenous infusion is the preferred method for use in emergency situations when rapid drug effects are desired. Absorption is considered to be instantaneous, as the drug is placed directly into the bloodstream. The subcutaneous and intramuscular routes could be used but would not ensure rapid drug effects. Intrathecal administration is usually done by a physician or a specially trained health care provider. Question 19 1 out of 1 points A patient has been prescribed an oral drug that is known to have a high first-pass effect. Which of the following measures has the potential to increase the amount of the free drug that is available to body cells? Response Feedback : Unlike oral medications, drugs that are given intravenously do not initially pass through the liver. As a result, the first-pass effect is mitigated and more of the drug is available to cells. Frequent oral doses, low protein intake, and administration with food do not reduce the first-pass effect. Question 20 1 out of 1 points A patient has been prescribed 1 mg lorazepam (Ativan) sublingual prior to the scheduled insertion of a peripherally inserted central (PIC) line. How should the nurse direct the patient when administering this medication? Response Feedback : Sublingual tablets are placed under the tongue where they dissolve and are absorbed into the bloodstream. Swallowing the pill may render it less effective, but is not
unsafe. It is not recommended to chew and hold sublingual medications nor to hold them in the mouth for length of time.
