A nurse is teaching a client who has a new prescription for an antacid to treat a gastric ulcer. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: "Antibiotics are administered to treat viral infections." is an incorrect statement for the nurse to make when providing teaching for a client who has a new prescription for an antibiotic. Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply. Antibiotics do not work against viruses, such as those that cause colds, flu, or COVID19. Taking antibiotics when they are not needed can cause harm and increase the risk of antibiotic resistance¹.

Choice B reason: "Bloody stools are expected while taking antibiotics." is an incorrect statement for the nurse to make when providing teaching for a client who has a new prescription for an antibiotic. Bloody stools are not a normal or expected side effect of antibiotics. They can indicate a serious condition, such as intestinal bleeding, ulcerative colitis, or Clostridioides difficile infection. C. diff is a type of bacteria that can cause severe diarrhea, abdominal pain, and bloody stools. It can occur when antibiotics disrupt the normal balance of bacteria in the gut and allow C. diff to grow and produce toxins. The nurse should instruct the client to report any signs of bloody stools or severe diarrhea to the health care provider immediately.

Choice C reason: "Take the entire course of antibiotics as prescribed." is a correct statement for the nurse to make when providing teaching for a client who has a new prescription for an antibiotic. Taking the entire course of antibiotics as prescribed is important to ensure that the infection is completely treated and to prevent the bacteria from becoming resistant to the antibiotic. Stopping the antibiotic too soon or skipping doses can allow some bacteria to survive and multiply, which can cause the infection to come back or spread to other parts of the body. The nurse should also remind the client to follow the instructions on the medication label or the prescriber's order regarding the dosage, frequency, and duration of the antibiotic therapy.

Choice D reason: "Discontinue the medication when you feel better." is an incorrect statement for the nurse to make when providing teaching for a client who has a new prescription for an antibiotic. Discontinuing the medication when the client feels better is not advisable, as it can lead to incomplete treatment and antibiotic resistance. Feeling better does not mean that the infection is gone or that the bacteria are all killed. The client should continue to take the antibiotic until the end of the prescribed course, even if they have no symptoms or feel better. The nurse should also advise the client to contact the health care provider if they have any questions or concerns about the antibiotic or if they experience any side effects or allergic reactions.

Choice A reason: Dextromethorphan (Robitussin) is not the correct medication for a patient with a productive cough. Dextromethorphan is a cough suppressant that works by acting on the brain to reduce the cough reflex. Dextromethorphan is used for a dry, nonproductive cough that is caused by irritation or inflammation. Dextromethorphan is not effective for a productive cough that produces mucus, and it may even be harmful by preventing the clearance of secretions from the lungs.

Choice B reason: Fluticasone (Flonase) is not the correct medication for a patient with a productive cough. Fluticasone is a corticosteroid that works by reducing inflammation and swelling in the nasal passages. Fluticasone is used for allergic rhinitis, which is a condition that causes sneezing, itching, and runny nose due to an allergic reaction. Fluticasone is not effective for a productive cough that produces mucus, and it may even worsen it by suppressing the immune system and increasing the risk of infection.

Choice C reason: Pseudoephedrine (Sudafed) is not the correct medication for a patient with a productive cough. Pseudoephedrine is a decongestant that works by constricting the blood vessels in the nasal passages and sinuses. Pseudoephedrine is used for nasal congestion, which is a condition that causes stuffy nose and difficulty breathing due to swelling of the mucous membranes. Pseudoephedrine is not effective for a productive cough that produces mucus, and it may even cause side effects such as increased blood pressure, insomnia, and anxiety.

Choice D reason: Guaifenesin (Mucinex) is the correct medication for a patient with a productive cough. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the chest and throat. Guaifenesin is used for a productive cough that produces mucus, as it helps the cough to be more effective and clear the airways. Guaifenesin is generally safe and well tolerated, but it may cause some minor side effects such as nausea, vomiting, and headache.
