The drugs on the list must be dispensed by the pharmacist using the drug's trade name as written on the prescription.

From your understanding of drug administration, which of the following routes will the nurse likely use? โ ANS Nasogastric (enteral) The nurse will not crush the extended-release medications ordered for his or patient because: - ANS Crushing alters the rate of absorption and medication delivery.

The student knows that: - ANS This abbreviation should not be used. Instead write out "every other day." Patients with liver disorder would most likely have problems with which pharmacokinetic phase? โ ANS Metabolism The patient asks the nurse why he or she must take his or her medication twice a day instead of just once. The nurse's best response would be: - ANS "Taking the medication twice a day ensures that maximum concentrations are maintained within the body." Which of the following principles are true about how medications work? For a drug to be effective, it must be potent For drug efficacy to occur, a lower dose must be administered Antagonists bind to receptors and produce responses to block agonists The agonist-receptor interaction causes a cellular response resulting in therapeutic action โ ANS Antagonists bind to receptors and produce responses to block agonists The agonist-receptor interaction causes a cellular response resulting in therapeutic action If a patient takes a medication on a full stomach, the medication will be ___________. โ ANS Absorbed more slowly When planning care for a patient, the nurse takes into consideration which of the following factors that could directly influence the effectiveness of the drugs that will be given?
