A nurse is providing discharge teaching for a patient who will be going home on cyclobenzaprine (Flexeril) prescribed for his acute musculoskeletal pain.
The nurse will stress that the patient should avoid what?

Choice A rationale

Guaifenesin is an expectorant that increases the output of respiratory tract fluid by reducing the adhesiveness and surface tension of the mucus, facilitating the removal of viscous mucus.

Choice B rationale

Dextromethorphan is a cough suppressant that works on the cough center in the brain to reduce the urge to cough. It does not enhance the output of respiratory tract fluid.

Choice C rationale

Acetylcysteine is a mucolytic that breaks down the chemical structure of mucus molecules, making the mucus less viscous, but it does not enhance the output of respiratory tract fluid by reducing adhesiveness.

Choice D rationale

Flunisolide is an inhaled corticosteroid used to reduce inflammation in the airways. It does not enhance the output of respiratory tract fluid.

Choice A rationale

Pharmacodynamics is the study of how drugs affect the body, including the mechanisms of action and the relationship between drug concentration and effect. It does not describe the actions of the nurses in this context.

Choice B rationale

Pharmacotherapeutics involves the use of drugs to diagnose, treat, and prevent disease. The actions of the nurses in administering iodine, chemotherapy, and vaccines are examples of pharmacotherapeutics, as they are using drugs for therapeutic purposes.

Choice C rationale

Pharmacoeconomics is the study of the cost and value of drugs and therapies. It does not describe the actions of the nurses in administering medications.

Choice D rationale

Pharmacokinetics is the study of how the body absorbs, distributes, metabolizes, and excretes drugs. It does not describe the actions of the nurses in this context.
