ATI: Infection Test
A nurse is caring for a client who is about to begin receiving acyclovir IV to treat a viral infection. The nurse should recognize that cautious use of the drug is essential if the client also has which of the following conditions? Heart failure Dehydration Asthma Tinnitus
Dehydration Acyclovir, an antiviral drug, can cause renal toxicity, especially in clients who are dehydrated. Hydration during and after IV infusion of the drug can help prevent crystalluria.
A nurse is caring for a client who is about to begin gentamicin therapy to treat an infection. The nurse should monitor the client for an alteration in which of the following? Bowel function Peripheral pulses Urine output Level of consciousness

When administering oral erythromycin to a client who has acute diphtheria, a nurse should monitor for which of the following adverse effects? Hypothermia Blurred vision Constipation Cardiac dysrhythmias
Cardiac dysrhythmias Erythromycin, a macrolide, can cause ECG changes, including a prolonged QT interval, and put the client at risk for a potentially fatal ventricular dysrhythmia.

A nurse is caring for a client who has a prescription for rifampin to treat tuberculosis. The nurse should expect the provider to prescribe which of the following drugs to the client to prevent possible resistance to rifampin? Gentamicin Vancomycin Isoniazid Metronidazole
Isoniazid Isoniazid is used to treat tuberculosis and reduces the possibility of resistance to rifampin when combined with the drug. Drug resistance can develop quickly if the client only takes rifampin.
A nurse is caring for a client who is about to begin taking isoniazid to treat tuberculosis. The nurse should instruct the client to report which of the following adverse effects of the drug? (Select all that apply.) Jaundice Numbness of the hands Dizziness Hearing loss Oral ulcers
Jaundice Numbness of the hands Dizziness Isoniazid, an antimycobacterial drug, can cause liver toxicity, especially in clients who abuse alcohol. The nurse should monitor liver enzymes during therapy and instruct the client to report indications of liver damage, such as jaundice, abdominal pain, and fatigue. Isoniazid can cause peripheral neuropathy. The nurse should instruct the client to report numbness, pain, or tingling in the hands or feet.

Which of the following findings in the client's medical record should the nurse recognize as requiring cautious use for this prescription and report to the provider? Glaucoma Closed-head injury Heart failure Renal impairment
Renal impairment Aztreonam, a monobactam, requires cautious use with clients who have renal dysfunction because it is excreted in the urine.

The nurse should report this finding to the provider, so the provider can prescribe a lower dose for the client or prescribe a different antimicrobial drug.
A nurse is caring for a client who is about to begin taking metronidazole to treat an anaerobic intra-abdominal bacterial infection. The nurse should recognize that cautious use of the drug is indicated if the client also has which of the following conditions? Seizure disorder Hearing loss Asthma Anemia

The nurse should identify that the client might be experiencing which of the following as an adverse effect of this drug? Malabsorption Superinfection Anorexia Dental caries
Superinfection Imipenem, a carbapenem, can cause the superinfection Candida albicans in the mouth, throat, or vagina. It can also cause glossitis, an inflammation or infection of the tongue.

A nurse is caring for a client who is about to begin taking itraconazole to treat a fungal infection. The nurse should instruct the client to report which of the following adverse effects of the drug? Tingling in the hands and feet Joint pain Swelling of hands or feet Excessive sweating
Swelling of hands or feet Itraconazole, an azole antifungal drug, can cause edema, which can also indicate heart dysfunction, and should be monitored closely.
A nurse in a provider's office receives a call from a client who is taking ciprofloxacin to treat a respiratory tract infection and reports dyspepsia. Which of the following instructions should the nurse give the client? Take an antacid at least 2 hr after taking the drug. Take the drug with a cup of coffee. Take an iron supplement with the drug. Take the drug with 240 mL (8 oz) of milk.
Take an antacid at least 2 hr after taking the drug. The nurse should recommend that the client take an antacid to relieve the dyspepsia at least 2 hr after taking ciprofloxacin, a fluoroquinolone. This is because antacids decrease the absorption of the drug.

This adverse effect is especially common for older adults or clients who take glucocorticoids, such as prednisolone. The nurse should tell the client to report tendon pain and stop taking the drug.
A nurse is caring for a client who has a new diagnosis of bacterial meningitis. The nurse should expect the provider to prescribe a drug from which of the following classifications of antibiotics? First generation cephalosporins Third generation cephalosporins Monobactams Macrolides
Third generation cephalosporins Later generation cephalosporins are used to treat infections that cross the blood-brain barrier, and third-generation are specifically prescribed to treat bacterial meningitis.
A nurse is providing teaching for a client who takes an oral contraceptive and is about to begin rifampin therapy to treat tuberculosis. Which of the following instructions should the nurse include? Increase the rifampin dose. Increase the oral contraceptive dose. Allow 2 hr between taking the two drugs. Use a non-hormonal form of contraception.
Use a non-hormonal form of contraception. Rifampin, an antimycobacterial drug, can increase the metabolism of oral contraceptives, reducing their effectiveness. Clients who are taking oral contraceptives and rifampin should use additional, non-hormonal contraceptive methods to prevent an unwanted pregnancy.
A nurse is caring for a client whose sputum culture results indicate methicillin-resistant Staphylococcus aureus (MRSA). The nurse should recognize that which of the following medications will likely be administered to this client? Trimethoprim/sulfamethoxazole Tetracycline Cephalexin Vancomycin
Vancomycin Vancomycin, a potentially toxic antibiotic, is used primarily to treat serious infections in clients who are allergic to penicillin or whose infecting bacteria are resistant to penicillin, such as MRSA.
