A nurse is caring for a 7-year-old child who has a fever, tachycardia, and low oxygen saturation. The nurse reviews the child's laboratory results and notes the following:
- WBC count 15,000/mm^3^ (normal range: 5,000 to 10,000/mm^3^)
- Hgb 8 g/dL (normal range: 10 to 15.5 g/dL)
- Hct 32% (normal range: 32% to 44%)
The nurse should suspect that the child has which of the following conditions?
Leukemia.
Sickle cell anemia.
Hemophilia.
Iron deficiency anemia.
The Correct Answer is B
Choice A reason: Leukemia is not a probable condition, as it is a cancer of the white blood cells that causes abnormal proliferation and accumulation of immature or dysfunctional white blood cells. The child has a high WBC count, which can indicate leukemia, but not necessarily. The child does not have other signs of leukemia, such as bleeding, bruising, bone pain, or lymphadenopathy.
Choice B reason: Sickle cell anemia is a possible condition, as it is an inherited disorder that affects the shape and function of the red blood cells, causing them to become sickle-shaped and rigid. The child has a low Hgb and Hct, which can indicate anemia, and a fever, tachycardia, and low oxygen saturation, which can indicate a sickle cell crisis. A sickle cell crisis is a condition where the sickle-shaped red blood cells block the blood flow and cause tissue ischemia and inflammation.
Choice C reason: Hemophilia is not a likely condition, as it is an inherited disorder that affects the clotting factors, causing impaired blood clotting and increased risk of bleeding. The child has a low Hgb and Hct, which can indicate anemia, but not necessarily hemophilia. The child does not have other signs of hemophilia, such as bleeding, bruising, hemarthrosis, or hematuria.
Choice D reason: Iron deficiency anemia is not a definite condition, as it is a type of anemia that occurs when the body does not have enough iron to produce hemoglobin, the protein that carries oxygen in the blood. The child has a low Hgb and Hct, which can indicate iron deficiency anemia, but not necessarily. The child does not have other signs of iron deficiency anemia, such as pallor, fatigue, weakness, or pica.

Correct Answer is A
Explanation
Choice A reason: Broad-spectrum antibiotics are indicated for septic shock caused by bacterial infection, as they can target a wide range of pathogens and prevent further sepsis. Fluid boluses are also essential to restore the intravascular volume and improve tissue perfusion and oxygenation.
Choice B reason: Antipyretics and oxygen therapy are not sufficient to treat septic shock, as they do not address the underlying infection or the hypovolemia. Antipyretics may lower the temperature, but they do not eliminate the bacteria. Oxygen therapy may improve the pulse oximeter reading, but it does not correct the hypoperfusion.
Choice C reason: Vasopressors and blood transfusions are not the first-line treatments for septic shock, as they may have adverse effects on the cardiovascular system and the coagulation cascade. Vasopressors may increase the blood pressure, but they may also cause vasoconstriction and reduce the blood flow to vital organs. Blood transfusions may increase the hemoglobin level, but they may also increase the risk of fluid overload, hemolysis, and transfusion reactions.
Choice D reason: Corticosteroids and antihistamines are not indicated for septic shock, as they do not have any proven benefits and may have harmful effects on the immune system and the inflammatory response. Corticosteroids may suppress the adrenal function and increase the risk of infection. Antihistamines may cause sedation and dryness of the mucous membranes.
Correct Answer is B
Explanation
Choice A reason: A protective environment is a type of isolation precaution that is used for patients who are immunocompromised and at high risk of infection from environmental sources, such as fungi or bacteria. It involves using a private room with positive air pressure, high-efficiency particulate air (HEPA) filtration, and strict hand hygiene. It is not indicated for patients who have measles, as they are the source of infection, not the susceptible host.
Choice B reason: Airborne is a type of isolation precaution that is used for patients who have diseases that are transmitted by small droplets that can remain suspended in the air and travel over long distances, such as tuberculosis, chickenpox, or measles. It involves using a private room with negative air pressure, HEPA filtration, and respiratory protection for health care workers and visitors. It is the appropriate isolation precaution for patients who have measles, as it prevents the spread of the virus to others.
Choice C reason: Contact is a type of isolation precaution that is used for patients who have diseases that are transmitted by direct or indirect contact with the patient or their environment, such as Clostridioides difficile, scabies, or impetigo. It involves using a private room or cohorting with similar patients, wearing gloves and gowns, and using dedicated equipment. It is not indicated for patients who have measles, as the disease is not spread by contact.
Choice D reason: Droplet is a type of isolation precaution that is used for patients who have diseases that are transmitted by large droplets that are generated by coughing, sneezing, or talking, such as influenza, pertussis, or meningitis. It involves using a private room or cohorting with similar patients, wearing a surgical mask, and maintaining a distance of at least 3 feet from the patient. It is not indicated for patients who have measles, as the disease is spread by airborne transmission.
