Pharm Module 2 Chapter 9 PrepU

A client has been on an antibiotic for two weeks for treatment of an infection. The client asks the nurse why a superinfection has been caused by this medication. What is the nurse's best response?

"Antibiotics can disrupt the normal bacteria in your body, causing another infection to occur."

Levofloxacin 750 mg IV is ordered for a client with a urinary tract infection. The medication is to mixed yielding 250 mg/15 mL. How many mL should be drawn up in the syringe?

45

The client has been started on levofloxacin (Levaquin) for a respiratory infection. The client is now experiencing sores in his mouth. The nurse suspects this is due to what type of superinfection?

Candidiasis

The client is complaining of vaginal itching after five days of fluoroquinolone therapy. The nurse suspects which of the following?

Candidiasis

A client who takes zinc daily is diagnosed with a severe infection and is ordered levofloxacin (Levaquin). The nurse is aware that taking these two drugs may have what affect on the antibiotic?

Decreased absorption

A client is receiving ciprofloxacin for a urinary tract infection. This drug is administered IV. During the infusion, the nurse notes fluid leaking into the tissue around the IV site. What is the best response of the nurse?

Discontinue the IV.

The nurse is providing client teaching before discharging a client home. The client is taking ciprofloxacin. What action should the nurse encourage the client to prioritize?

Drink at least 2L of fluid per day.

A client is prescribed ciprofloxacin for an acute sinus infection. The nurse knows that this anti-infective medication belongs to which drug category?

Fluoroquinolones

Which of the following classes of antibiotics is a direct inhibitor of DNA synthesis in bacteria?

Fluoroquinolones

The pharmacology instructor is discussing antimicrobials with the nursing class. What would the instructor tell the students is the mechanism of action of some antimicrobials?

Inhibiting cell wall synthesis

A nurse knows that promoting an optimal response to drug therapy is a desired outcome for clients on fluoroquinolones. One important action the nurse should include in the plan of care is which?

Observe the client for the first 48 hours for adverse reactions to the drug.

When preparing to administer a fluoroquinolone, the nurse understands that the majority of drugs belonging to this class are administered by which route?

Oral

A young lifeguard has been prescribed moxifloxacin (Avelox). The nurse understands that the focus on education would be which adverse reaction?

Photosensitivity

The client has been taking her antibiotic for five days. She tells the nurse that she is now experiencing vaginal itching and discharge. The nurse suspects what has occurred?

The client has developed a superinfection.

An older adult client has a feeding tube in place to manage dysphagia. After developing an infected pressure ulcer, ciprofloxacin suspension has been prescribed via feeding tube. How should the nurse follow-up this prescription?

The nurse should liaise with the health care provider to provide an alternative route of administration. Explanation: Administration of the oral suspension of ciprofloxacin via feeding tubes should not occur, because the oil-based formulation tends to adhere to the feeding tube. An alternative route is consequently necessary. None of the other options would address the problem of adherence sufficiently.

A 30-year-old woman who is in the first trimester of pregnancy has presented to her primary care provider with a 4-day history of a reddened, itchy left eye that is crusted with purulent exudate. The clinician suspects a bacterial, rather than viral, etiology. How will the client's pregnancy affect the potential use of ciprofloxacin to treat her conjunctivitis?

The use of ciprofloxacin is contraindicated in pregnancy.

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?

They disrupt the normal flora of the body.

Prior to administering fluoroquinolones, it is most important for the nurse to assess for which finding or condition?

allergies.

Tendinitis has been reported with the use of fluoroquinolones. The nurse instructs the client to report any pain or soreness in which area? Select all that apply.

back of the heel, leg, shoulder

When describing the action of fluoroquinolones to treat infection to a group of nursing students, which action would the instructor most likely include?

bactericidal

The nurse identifies Zyvox, the first drug in a new class called the oxazolidinones, to be which of the following? (Select all that apply.)

bacteriostatic bactericidal

changing to a different antibiotic

The client has been prescribed a fluoroquinolone. The nurse knows that nursing interventions for clients taking fluoroquinolones include which?

increase fluid intake

A nursing instructor is preparing a teaching plan for a nursing pharmacology class on the action of fluoroquinolones. Which action would the instructor most likely include?

interfering with DNA synthesis in the bacterial cell

A group of nursing students are reviewing information about fluoroquinolones. The students demonstrate a need for additional review when they identify which as an example?

metronidazole

What route of administration is most commonly used for the administration of ciprofloxacin when prescribed to an older adult client?

oral (PO)

A client is receiving levofloxacin (Levaquin) IV. During an infusion, the client reports pain and the nurse notes a reddened area along the vein. What does the nurse suspect?

phlebitis

A client is prescribed ciprofloxacin 500 mg PO twice a day. When would the nurse most likely administer the drug?

twice daily PO, 2 hours after the meal

The nursing student correctly identifies the class of drugs that exerts their bactericidal effect by interfering with the synthesis of bacterial DNA, thus preventing cell reproduction and leading to death of the bacteria, as which of the following groups?

Fluoroquinolones
