(Select all that apply) A client is receiving ciprofloxacin IV for a severe infection caused by Pseudomonas aeruginosa.
Which of the following laboratory tests should the nurse monitor for adverse effects of this medication?

Ciprofloxacin is an antibiotic that can cause various side effects, some of which are serious and may be permanent.

The nurse should monitor the following laboratory tests for adverse effects of this medication:

• Liver function tests: Ciprofloxacin can cause hepatotoxicity, which is damage to the liver cells.Liver function tests can detect abnormal levels of enzymes or bilirubin that indicate liver injury.

• Serum creatinine levels: Ciprofloxacin can cause nephrotoxicity, which is damage to the kidney cells.

Serum creatinine levels can measure how well the kidneys are filtering waste products from the blood.Elevated serum creatinine levels indicate impaired kidney function.

• Complete blood count: Ciprofloxacin can cause hematologic disorders, such as anemia, leukopenia, thrombocytopenia, or pancytopenia.

A complete blood count can evaluate the number and quality of red blood cells, white blood cells, and platelets in the blood.Abnormal blood counts can increase the risk of bleeding, infection, or fatigue.

Choice B is wrong because ciprofloxacin does not affect blood glucose levels directly.

However, ciprofloxacin can interact with some oral antidiabetic drugs and increase the risk of hypoglycemia or hyperglycemia.Therefore, the nurse should monitor the blood glucose levels of diabetic patients who are taking ciprofloxacin and other antidiabetic drugs.

Choice E is wrong because ciprofloxacin does not affect thyroid function tests directly.

However, ciprofloxacin can interact with some thyroid hormone replacement drugs and decrease their absorption or efficacy.Therefore, the nurse should monitor the thyroid function tests of patients who are taking ciprofloxacin and thyroid hormone replacement drugs.

This statement indicates a need for further education because oseltamivir does not prevent the transmission of influenza virus to others.Oseltamivir is an antiviral drug that can shorten the duration of symptoms, reduce the risk of complications, and work best if started within 48 hours of symptom onset. However, it does not eliminate the virus from the body or provide immunity against future infections.Therefore, the client should still practice good hygiene and avoid contact with others who are at high risk of influenza complications.

Choice A is wrong because oseltamivir can shorten the duration of symptoms by about one day if taken within 48 hours of symptom onset.

Choice C is wrong because oseltamivir works best if started within 48 hours of symptom onset, as it inhibits the viral replication and reduces the viral load.

Choice D is wrong because oseltamivir may cause nausea and vomiting as side effects in some people, especially if taken without food.These side effects are usually mild and transient and can be minimized by taking the medication with food or milk.
