A nurse is planning care for a child who has a prescription for somatropin.
Which of the following interventions should the nurse include to evaluate the therapeutic effect of this medication?

Choice A rationale

Tuberculosis is a bacterial infection primarily affecting the lungs, caused by *Mycobacterium tuberculosis*. Didanosine is an antiretroviral medication, specifically a nucleoside reverse transcriptase inhibitor (NRTI), and as such, it does not possess antimicrobial activity against bacterial pathogens like *Mycobacterium tuberculosis*. Therefore, it is not indicated for treating tuberculosis.

Choice B rationale

Human immunodeficiency virus (HIV) is a retrovirus that attacks the body's immune system. Didanosine is an antiretroviral drug that inhibits the replication of HIV by interfering with the reverse transcriptase enzyme, which is crucial for the virus to convert its RNA into DNA. This mechanism of action effectively reduces the viral load and improves immune function in individuals with HIV infection.

Choice C rationale

Bacterial meningitis is an inflammation of the meninges, the membranes surrounding the brain and spinal cord, caused by various bacterial species. Didanosine is an antiviral agent specifically targeting retroviruses like HIV. It does not have any direct antibacterial properties or efficacy against the common bacterial pathogens responsible for meningitis, thus making it an inappropriate treatment.

Choice D rationale

Syphilis is a sexually transmitted infection caused by the bacterium *Treponema pallidum*. The primary treatment for syphilis is antibiotics, particularly penicillin. Didanosine, being an antiretroviral medication, does not exhibit any treponemicidal activity and is ineffective against *Treponema pallidum*. Therefore, it is not used in the treatment of syphilis.

Choice A rationale

Administering aspirin for fever in a client receiving alteplase is contraindicated. Alteplase is a potent thrombolytic, and aspirin, an antiplatelet agent, would significantly increase the risk of bleeding. If fever is present, acetaminophen would be the preferred antipyretic due to its lack of antiplatelet activity, minimizing the risk of hemorrhage in this high-risk patient.

Choice B rationale

Ambulation is contraindicated in a client receiving thrombolytic therapy. Alteplase lyses existing clots, increasing the risk of bleeding, especially from sites of trauma or increased pressure. Maintaining bed rest and limiting movement helps to minimize the risk of hemorrhagic complications, such as hematoma formation or internal bleeding, which could be exacerbated by physical activity.

Choice C rationale

Administering a sodium phosphate enema is contraindicated in a client receiving thrombolytic therapy. Sodium phosphate enemas can cause rectal irritation, mucosal injury, and increased peristalsis, all of which elevate the risk of gastrointestinal bleeding in a patient whose coagulation cascade is already significantly impaired by alteplase. Stool softeners are preferred if constipation is present.

Choice D rationale

Monitoring for changes in the level of consciousness is a critical intervention for a client receiving alteplase. Intracranial hemorrhage is the most serious and life-threatening complication of thrombolytic therapy. Any alterations in neurological status, such as confusion, disorientation, or decreased responsiveness, could indicate intracranial bleeding and necessitate immediate intervention and discontinuation of the infusion.
