Karch Sixth Edition Chapter 9 Prep U Exam Questions With 100% Correct Answers Before the selection of an aminoglycoside to treat a client's wound infection, what would the nurse expect the physician to order? - answerCulture and sensitivity The choice of aminoglycoside depends on local susceptibility patterns and specific organisms causing an infection. A client has a diagnosis of otitis media and has just begun antibiotic treatment. The client reports otalgia and has asked for medication.

The nurse knows that pseudomembranous colitis is a superinfection of fluoroquinolones, especially when they are administered in high doses, because these medications have what effect in the body? - answerThey disrupt the microbial flora of the body. Pseudomembranous colitis is a superinfection that occurs when the antibiotic disrupts the normal flora, causing a secondary infection or superinfection. A patient with septicemia is administered cefotaxime sodium (Claforan). How is this medication excreted? - answerIt is excreted by the kidneys. Cefotaxime sodium is excreted by the kidneys. Cefotaxime is not excreted by the lungs, liver, or skin. The nurse receives a call from a client who is taking clindamycin (Cleocin) and reports of a burning feeling when swallowing. The nurse knows that the client has developed which adverse reaction related to this medication? - answeresophagitis The client reports esophagitis (an inflammation of the esophagus) that may be seen in clients taking clindamycin.

(less) The nurse is providing care for a teenager with otitis media. When assessing the patient for potentially adverse effects of Cortisporin Otic, what question should the nurse ask? - answer"Have you noticed any loss of hearing since you started taking the drops?" It is necessary to assess the patient taking Cortisporin Otic for signs of hearing loss due to ototoxicity. Fever, bleeding, and headaches are not typical adverse effects. A patient has been admitted to the intensive care unit with signs and symptoms of sepsis and preliminary results of the patient's initial blood cultures reveal the presence of methicillin- resistant Staphylococcus aureus (MRSA). This finding is an indication for treatment with? - answerdaptomycin. Daptomycin is FDA approved for treatment of bacteremia due to S. aureus (including MRSA). Ciprofloxacin, levofloxacin and polymyxin B are not typically used in cases of MRSA sepsis. (less) A nurse teaching the patient with tuberculosis (TB) should include the following information about ethambutol: - answerIt can cause optic neuritis.

Which of the following medications will be administered? - answerErythromycin (Ery-Tab) A patient who is diagnosed with a genitourinary infection that is caused by trachomatis and who is allergic to penicillin should be administered erythromycin (Ery-Tab). Acamprosate calcium is administered as a substance abuse deterrent, not in place of penicillin. Atazanavir (Reyataz) is an antiviral agent that is used to treat HIV infection, not Chlamydia trachomatis. Flumazenil is a benzodiazepine antagonist and not used for Chlamydia trachomatis. (less) A patient is hospitalized due to noncompliance with an antitubercular drug treatment. Which of the following is most important for the nurse to do? - answerObserve the patient taking the medications Directly observed therapy in which a health care provider observes the patient taking each dose of anti-TB drugs is recommended for all drug regimens and is considered mandatory in this case.

How should the nurse account for this patient's health status when planning care during INH treatment? - answerThe patient will require vigilant monitoring of blood glucose levels. INH treatment constitutes a risk for hyperglycemia and close monitoring of blood glucose levels is thus indicated. This patient's history will not likely impact the chosen route for the drug and insulin therapy can be safely continued. The patient will be vulnerable to other infections for the foreseeable future, but he will not likely be immunocompromised to the degree that positive-pressure isolation is required. (less) A client is prescribed ciprofloxacin for a urinary tract infection. The nurse is preparing to teach the client about the medication.
