A patient with a viral infection is to receive ganciclovir (Cytovene) 5 mg/kg/day IVPB every morning.

The patient weighs 110 pounds.

Identify how many milligrams this patient will receive for this dose.

Choice A rationale

Oseltamivir, an antiviral neuraminidase inhibitor, is most effective when administered within 48 hours of influenza symptom onset. It works by inhibiting the viral neuraminidase enzyme, preventing the release of new virions from infected cells, thereby reducing viral spread and shortening the duration and severity of illness, if given early.

Choice B rationale

Rest is indeed important for recovery from influenza, as it conserves energy and allows the immune system to combat the infection. However, decreasing fluid intake is contraindicated; adequate hydration is crucial to prevent dehydration, especially with fever, and to help thin respiratory secretions, facilitating their clearance.

Choice C rationale

Influenza is a viral infection; therefore, antibiotics, which target bacterial pathogens, are ineffective against the influenza virus itself. Administering antibiotics would be inappropriate and could contribute to antibiotic resistance without providing therapeutic benefit for the viral illness, unless a secondary bacterial infection is suspected.

Choice D rationale

Admission to an acute care facility is generally reserved for severe cases of influenza, such as those with respiratory distress, hypoxemia, or significant comorbidities. For a patient whose symptoms started only 24 hours prior and without severe complications, outpatient management with antiviral therapy is typically sufficient.

Choice A rationale

Treatment for pulmonary tuberculosis with rifampin is typically prolonged, lasting for several months, often 6 to 9 months, not just 1 month. Shortening the treatment duration significantly increases the risk of drug resistance and recurrence of the infection. Adherence to the full regimen is critical for eradication.

Choice B rationale

Rifampin is not typically associated with causing insomnia. Common side effects include gastrointestinal upset, hepatotoxicity, and discoloration of body fluids. Insomnia is more commonly linked to other medications or underlying conditions, not a characteristic side effect of rifampin directly impacting sleep architecture.

Choice C rationale

Taking rifampin with meals is generally not recommended as food can impair its absorption, reducing its bioavailability and therapeutic effectiveness. It is typically advised to take rifampin on an empty stomach, either 1 hour before or 2 hours after meals, to ensure optimal drug absorption and efficacy.

Choice D rationale

Rifampin causes a harmless but noticeable orange-red discoloration of urine, sweat, tears, and other body secretions. This is due to the drug's inherent color and its excretion pathways. Clients should be informed of this expected side effect to prevent anxiety and ensure adherence to the medication regimen.
