Order: Ceftriaxone 300 mg IV Q12H for a 6 month old infant with a serious infection who weighs 18 lbs. The recommended dosage is 50-75 mg/kg/day in divided doses BID. Prove mathematically (mg/kg/day) the ordered dose and is it safe to give Safe/Unsafe)?

A. Pertussis:

Pertussis, commonly known as whooping cough, is caused by the bacterium Bordetella pertussis. It is characterized by a persistent cough with a distinctive "whoop" sound during the inspiratory phase. The cough can be severe and may last for several weeks. The characteristic whooping sound is due to the rapid intake of breath after a coughing episode.

B. Asthma:

Asthma is a chronic respiratory condition characterized by recurrent episodes of wheezing, coughing, and shortness of breath. It is not typically associated with a whooping sound during the inspiratory phase. Asthma symptoms are often triggered by factors such as allergies, exercise, or exposure to irritants.

C. Bronchiolitis:

Bronchiolitis is commonly caused by respiratory syncytial virus (RSV), especially in infants. It presents with symptoms such as cough, wheezing, and respiratory distress. However, it does not involve the characteristic whooping cough sound seen in pertussis.

D. Acute Laryngotracheobronchitis (LTB):

Acute Laryngotracheobronchitis, or croup, is characterized by a barking cough, stridor (a high-pitched sound during inhalation), and respiratory distress. It is common in young children and is often caused by viruses. Unlike pertussis, it does not typically include the distinctive whooping sound.

A. Preventing spread of infection:

This is a priority because individuals with acquired immunodeficiency syndrome (AIDS) have a compromised immune system. Preventing the spread of infections is crucial to avoid additional complications and safeguard the individual's health.

B. Maintaining skin integrity:

Skin integrity is important for overall health, but in the context of AIDS, preventing infections and promoting immune function take precedence over maintaining skin integrity. Skin issues might be secondary to the immune system's compromised state.

C. Improving nutrition:

Good nutrition is important for overall health, including supporting the immune system. However, preventing the spread of infection is more immediate and critical in the case of someone with AIDS. Addressing nutritional needs can be part of the overall care plan but might be secondary to preventing infections.

D. Promoting comfort:

While promoting comfort is essential in nursing care, the priority in the case of a child with AIDS would be preventing the spread of infection due to the immunocompromised state. Comfort measures may be incorporated into the care plan, but they would not take precedence over preventing further health complications.
