B. Reduction of fever C. Sterile sputum cultures D. Oxygen saturation of 98%

A patient is prescribed doxycycline [Vibramycin]. If the patient complains of gastric irritation, what should the nurse do? a. Instruct the patient to take the medication with milk b. Tell the patient to take an antacid with the medication c. Give the patient food, such as crackers or toast, with the medication d. Have the patient stop the medication immediately and contact the health care provider

C. Give the patient food, such as crackers or toast, with the medication Rationale: Tetracyclines form insoluble chelates with calcium, iron, magnesium, aluminum, and zinc; absorption is decreased. Tetracyclines should not be administered together with milk or antacids. Long-acting tetracyclines, such as doxycycline, may be taken with food; food does not affect absorption.

A patient who was taking sulfonamides develops Stevens-Johnson syndrome. Upon assessment, the nurse expects to find what? a. Hypotension b. Bronchospasm c. Temperature of 35.5º C d. Widespread skin lesions

D. Widespread skin lesions The most severe hypersensitivity response to sulfonamides is Stevens-Johnson syndrome, a rare reaction with a mortality rate of about 25%. Symptoms include widespread lesions of the skin and mucous membranes, combined with fever, malaise, and toxemia. Bronchospasm and hypotension, as well as tachycardia, are manifestations of anaphylactic reactions.

"Tetracycline can be harmful to the baby's teeth and should be avoided." b."Tetracycline may cause allergic reactions in pregnant women." c."Tetracycline will prevent asymptomatic urinary tract infections." d. "Tetracycline is safe to take during pregnancy."

a. "Tetracycline can be harmful to the baby's teeth and should be avoided."

Which statement about allergic reactions to penicillin does the nurse identify as true? a. Anaphylactic reactions occur more frequently with penicillins than with any other drug. b. Allergy to penicillin always increases over time. c. Benadryl is the drug of choice for anaphylaxis due to penicillin allergy. d. Patients allergic to penicillin are also allergic to vancomycin.

a. Anaphylactic reactions occur more frequently with penicillins than with any other drug. Rationale: Anaphylactic reactions occur more frequently with penicillins than with any other drug. Allergy to penicillin can decrease over time. Epinephrine is the drug of choice for anaphylaxis. Vancomycin, erythromycin, and clindamycin are effective and safe alternatives for patients with penicillin allergy.

A patient with no known drug allergies is receiving amoxicillin [Amoxil] PO twice daily. Twenty minutes after being given a dose, the patient complains of shortness of breath. The patient's blood pressure is 100/58 mm Hg. What will the nurse do? a. Contact the provider and prepare to administer epinephrine. b. Withhold the next dose until symptoms subside. c. Request an order for a skin test to evaluate possible PCN allergy. d. Notify the provider if the patient develops a rash.

a. Contact the provider and prepare to administer epinephrine.

A patient with a history of a severe anaphylactic reaction to penicillin has an order to receive cephalosporin. What should the nurse do? a. Administer the cephalosporin as ordered. b. Contact the health care provider for a different antibiotic. c. Administer a test dose of cephalosporin to determine reactivity. d. Have an epinephrine dose available when administering the cephalosporin.

b. Contact the health care provider for a different antibiotic. Rationale: A few patients with penicillin allergy (about 1%) display cross-sensitivity to cephalosporins. If at all possible, patients with penicillin allergy should not be treated with any member of the penicillin family. Use of cephalosporins depends on the intensity of the allergic response to penicillin; if the penicillin allergy is mild, use of cephalosporins is probably safe. However, if the allergy is severe, cephalosporins should be avoided.

The nurse is preparing to administer 30 units of NPH to client. He finds that the vial of insulin looks cloudy and uneven in appearance. Which of the following is the appropriate action? a. Discard the vial of NPH and open a new one b. Shake the vial of NPH thoroughly then administer the dose c. Hold the dose and alert the prescriber d. Give the client 10 units of regular insulin

A nurse is explaining to nursing students why a cephalosporin is used in conjunction with an aminoglycoside for a patient with an infection. Which statement by a student indicates a. "Cephalosporins reduce bacterial resistance to aminoglycosides." b. "Cephalosporins prevent neuromuscular blockade associated with aminoglycosides." c. "Cephalosporins prolong the postantibiotic effects of the aminoglycosides so doses can be decreased." d. "Cephalosporins enhance the actions of aminoglycosides by weakening bacterial cell walls."

d. "Cephalosporins enhance the actions of aminoglycosides by weakening bacterial cell walls."

Which information should the nurse include when teaching a patient about rifampin therapy? a. Oral contraceptives are safe to use with rifampin therapy. b. Contact your healthcare provider immediately if the color of your body fluids changes to reddish orange. c. Rifampin is safe to use in patients who have hepatic disease. d. Rifampin may be administered intravenously.

D. Rifampin may be administered intravenously. Rationale: Rifampin may be administered intravenously. Women taking oral contraceptives should consider a nonhormonal form of birth control while taking rifampin. Rifampin frequently imparts a red-orange color to urine, sweat, saliva, and tears; patients should be informed of this harmless effect. Permanent staining of soft contact lenses occasionally has occurred, so the patient should consult an ophthalmologist about contact lens use. Rifampin is toxic to the liver, posing a risk of jaundice and even hepatitis. Asymptomatic elevation of liver enzymes occurs in about 14% of patients. However, the incidence of overt hepatitis is less than 1%. Hepatotoxicity is most likely in alcohol abusers and patients with pre-existing liver disease. These individuals should be monitored closely for signs of liver dysfunction.

Both IV ampicillin/sulbactam [Unasyn] and gentamicin are ordered for a patient. When administering these medications, the nurse will do what? Ensure that separate IV solutions are used. Use two different peripheral IV sites. Administer the gentamicin first. There are no necessary precautions.

Ensure that separate IV solutions are used. When penicillins are present in high concentrations, they interact chemically with aminoglycosides, causing inactivation of the aminoglycosides. Therefore, penicillins and aminoglycosides should not be mixed in the same IV solution.

When people wear face masks in public to reduce the spread of COVID 19 which link in the chain of infection transmission is being interrupted? a. Port of Exit AND Port of Entry b. Reservoir c. Susceptibility of victim d. Port of Entry

a. Port of Exit AND Port of Entry

a. up to 10 hours

A patient is prescribed cefixime. The nurse should teach the patient to immediately report any signs of what? a. Milk intolerance b. Skin rash, hives, or itching c. Constipation, nausea, or vomiting d. Headache, contusions, or seizures

b. Skin rash, hives, or itching Rationale: Hypersensitivity reactions are common with cephalosporins. Patients should be instructed to report any signs of allergy, such as skin rash, itching, or hives. Cefditoren contains a milk protein and should not be prescribed for patients with a milk protein allergy. Cefoperazone and cefotetan can promote bleeding. Diarrhea associated with antibiotic-associated pseudomembranous colitis (AAPMC) is a possible side effect with cephalosporins.

Which statement about superinfections does the nurse identify as true? a. Superinfections are more common in patients treated with narrow-spectrum drugs. b. Superinfection is defined as a new infection that appears. during the course of treatment for a primary infection. c. Superinfections are caused by viruses. d. Superinfections are easy to treat.

b. Superinfection is defined as a new infection that appears. during the course of treatment for a primary infection. Rationale: Because broad-spectrum antibiotics kill off more normal flora than do narrow-spectrum drugs, superinfections are more likely in patients receiving broad-spectrum agents. Suprainfections are caused by drug-resistant microbes; these infections are often difficult to treat.

A patient has been prescribed oral ciprofloxacin [Cipro] for a skin infection. When administering the medication, it is most important for the nurse to do what? a. Monitor for a decrease in the prothrombin time (PT) if the patient is also taking warfarin [Coumadin] b. Withhold antacids and milk products for 6 hours before or 2 hours afterward c. Inform the healthcare provider if the patient has a history of asthma d. Assess the skin for Stevens-Johnson syndrome

b. Withhold antacids and milk products for 6 hours before or 2 hours afterward Rationale: Absorption of ciprofloxacin can be reduced by ingestion of antacids and milk products. Ingestion of these products should occur at least 6 hours before ciprofloxacin or 2 hours afterward. Ciprofloxacin can increase the PT if the patient is also taking warfarin. Use of ciprofloxacin is contraindicated in patients with a history of myasthenia gravis. Patients taking ciprofloxacin are at risk for development of phototoxicity.
