Ampicillin 500 mg IM daily is ordered for your patient.

After reconstitution with 5 ml of sterile water, the vial of Ampicillin contains a total of 500 mg/ml. How many milliliters will your patient receive per day?

Choice A rationale

Meningococcal meningitis requires strict droplet precautions and intensive antibiotic therapy, but the management of the patient's stability often aligns with medical-surgical nursing competencies. While the patient is in the ICU for monitoring, the core tasks involve administering intravenous medications and monitoring for standard neurological changes. This makes the patient the most stable and appropriate choice for a float nurse who may not be proficient with specialized ICU-specific equipment or advanced hemodynamic monitoring.

Choice B rationale

A patient who is only one day post-craniotomy for a skull fracture is in a highly critical and unstable period. These patients require frequent, expert neurological assessments every hour to detect subtle signs of increasing intracranial pressure, hemorrhage, or herniation. A medical unit nurse lacks the specific training and daily experience required to manage a fresh post-operative neurosurgical patient, as these cases often involve complex nursing interventions and rapid titration of specialized medications.

Choice C rationale

The presence of an intracranial pressure (ICP) monitor requires specialized knowledge of transducer leveling, zeroing, and waveform interpretation. ICU nurses receive specific training to manage these invasive devices and to calculate cerebral perfusion pressure (CPP). A nurse floating from a medical unit would not have the competency to manage or troubleshoot an ICP monitor, making this assignment unsafe. The risk of infection and technical error is too high for a non-ICU nurse.

Choice D rationale

Hyperventilation therapy is a controlled intervention used to induce hypocapnia, which causes cerebral vasoconstriction and reduces intracranial pressure. This requires very close monitoring of arterial blood gases and ventilator settings to keep carbon dioxide levels within a specific, narrow range. This is a high-acuity intervention that is strictly managed by experienced critical care nurses and respiratory therapists. A float nurse would not have the necessary expertise to manage this specialized physiological manipulation.

Choice A rationale

Rest and watchful waiting are typically management strategies used for acute hepatitis A or sometimes acute hepatitis B, but they are not the standard of care for chronic hepatitis C. Chronic hepatitis C is a progressive viral infection that leads to liver fibrosis, cirrhosis, and hepatocellular carcinoma if left untreated. Because the virus continuously replicates and causes ongoing inflammatory damage to the hepatocytes, a passive approach is scientifically inadequate to prevent long term liver failure and mortality.

Choice B rationale

Immune globulins provide passive immunity and are used for post-exposure prophylaxis in hepatitis A or hepatitis B to prevent the development of an active infection. However, immune globulin has no proven efficacy in treating a well-established chronic hepatitis C infection. The hepatitis C virus has high genetic variability and undergoes rapid mutation, making it an ineffective target for standard immune globulin preparations. Treatment requires direct action against the viral replication cycle rather than a temporary immune boost.

Choice C rationale

Antiviral medications, specifically direct-acting antivirals, are the definitive treatment for chronic hepatitis C. These drugs work by targeting specific nonstructural proteins of the virus, such as NS3/4A, NS5A, or NS5B, which are essential for viral RNA replication and assembly. Modern regimens can achieve a sustained virologic response, which is effectively a cure, in over 95 percent of patients. Clearing the virus stops the progression of liver inflammation and allows the hepatic tissue to begin healing.

Choice D rationale

Fresh-frozen plasma is a blood product used to replace clotting factors in patients with severe coagulopathy or active bleeding, often seen in end-stage liver disease. While a patient with chronic hepatitis C might eventually need fresh-frozen plasma if they develop advanced cirrhosis and liver failure, it is not a treatment for the hepatitis C virus itself. It only manages the symptomatic complications of liver dysfunction rather than addressing the underlying viral etiology responsible for the hepatic damage.
