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 D
Explanation
Choice A reason: Holding the infant's chin to his chest and knees to his abdomen during the procedure is not a correct action for the nurse to take. This position may cause spinal cord compression or respiratory distress in the infant. The nurse should position the infant on his side with his back arched and his head and knees flexed.
Choice B reason: Placing the infant in an infant seat for 2 hr following the procedure is not a correct action for the nurse to take. This position may increase the intracranial pressure and cause headaches or vomiting in the infant. The nurse should keep the infant flat or slightly elevated for 4 to 6 hr after the procedure.
Choice C reason: Keeping the infant NPO for 6 hr prior to the procedure is not a correct action for the nurse to take. This may cause dehydration or hypoglycemia in the infant. The nurse should follow the provider's orders for fasting, which are usually 2 to 4 hr for clear liquids and 4 to 6 hr for solids.
Choice D reason: Applying a eutectic mixture of lidocaine and prilocaine cream topically 15 min prior to the procedure is a correct action for the nurse to take. This is a topical anesthetic that can reduce the pain and discomfort of the needle insertion. The nurse should apply the cream to the lower back and cover it with an occlusive dressing.
Correct Answer is B
Explanation
Choice A reason: Glyburide is an oral medication that lowers blood sugar by stimulating the pancreas to produce more insulin. It is not used for type 1 diabetes mellitus, as the pancreas cannot produce enough insulin in this condition. Glyburide is used for type 2 diabetes mellitus, which is caused by insulin resistance.
Choice B reason: Obtaining an influenza vaccine annually is recommended for people who have type 1 diabetes mellitus, as they are more prone to complications from the flu, such as pneumonia, ketoacidosis, and hospitalization. The vaccine can help prevent or reduce the severity of the flu and its complications.
Choice C reason: Injecting insulin in the deltoid muscle is not the best practice for administering insulin, as the absorption rate and onset of action may vary depending on the muscle mass and blood flow. The preferred sites for insulin injection are the abdomen, the upper arms, the thighs, and the buttocks, as they have more subcutaneous fat and less muscle tissue. The injection site should also be rotated to prevent lipodystrophy.
Choice D reason: Administering glucagon for hyperglycemia is not appropriate, as glucagon is a hormone that raises blood sugar by stimulating the liver to release glucose. It is used for hypoglycemia, or low blood sugar, which is a common and serious complication of type 1 diabetes mellitus. Hyperglycemia, or high blood sugar, is treated with insulin, fluids, and electrolytes.
