  NURS 6521 Week 1 Quiz 1Â
• Question 1
1 out of 1 points
In which of the following patients would a nurse expect to experience alterations in drug metabolism?
Response Feedback: The liver is the most important site for drug metabolism. If the liver is not functioning effectively, as with cirrhosis, drugs will not be metabolized normally and toxic levels could develop. Drug dosage will have to be altered to ensure normal levels in the body. The patient with kidney stones and the patient in acute renal failure would most likely have alterations in drug excretion. If there are no complications with the cervical cancer patient, there should be no alterations in drug therapy.
• Question 2
1 out of 1 points
The nurse's assessment of a community-dwelling adult suggests that the client may have drug allergies that have not been previously documented. What statement by the client would confirm this?
Response Feedback: True allergic reactions include formation of rash or hives, itching, redness, swelling, difficulty breathing, and anaphylactic shock. Nausea and vomiting, however, are adverse effects of drug therapy. Similarly, an unsafe drop in blood pressure and gastric bleeding from aspirin use are adverse drug effects, not allergic reactions.
• Question 3
0 out of 1 points
A patient who has ongoing pain issues has been prescribed meperidine (Demerol) IM. How should the nurse best administer this medication?
Response Feedback: The ventrogluteal site is the preferred site for intramuscular injection. IM injections necessitate the use of a larger gauge needle than is required for subcutaneous injections.
• Question 4
1 out of 1 points
A patient with a variety of chronic health problems is being seen by her nurse practitioner, who is currently reviewing the patient's medication regimen. Which of the patient's medications should prompt the nurse to teach her to avoid drinking grapefruit juice?
Response Feedback: Metabolism of many varied drugs such as calcium channel blockers (used to treat hypertension), statins (used to lower blood lipid levels), and antihistamines (used to prevent allergic reactions) is affected by grapefruit juice.
• Question 5
1 out of 1 points
A nurse is discussing with a patient the efficacy of a drug that his physician has suggested, and he begin taking. Efficacy of a drug means which of the following?
Response Feedback: Efficacy indicates how well a drug produces its desired effect. Different drugs have different strengths of attraction or affinity for receptor sites. A drug's ability to stimulate its receptor is called its intrinsic activity, and the amount of a drug that must be given to produce a particular response is called the potency of a drug.
