A complete blood workup is ordered for a 5 month old with tetralogy of Fallot. Because of the infant's heart disease, the nurse would expect the report to show:

Correct Answer: B

Rationale: Tetralogy of Fallot is a congenital heart defect that affects the flow of blood through the heart. In this condition, there is decreased pulmonary blood flow leading to reduced oxygenation of the blood. To compensate for the low oxygen levels in the blood, the body may increase the production of red blood cells, resulting in polycythemia (an increased red blood cell count). This is the body's way of trying to ensure that enough oxygen is carried to the tissues despite the heart defect. Therefore, in a 5-month-old infant with tetralogy of Fallot, the nurse would expect the blood workup to show polycythemia.

Correct Answer: B

Rationale: Diaphoresis, which refers to excessive sweating, is a common clinical feature seen in a hypoglycemic reaction. Hypoglycemia occurs when the blood sugar level drops too low, leading to symptoms like sweating, shakiness, confusion, and rapid heartbeat. On the other hand, ketoacidosis is a serious complication of diabetes that occurs when there is a lack of insulin, causing high blood sugar levels and the body to break down fat for energy. Symptoms of ketoacidosis include nausea, vomiting, abdominal pain, and fruity-smelling breath, but diaphoresis is not typically a prominent feature. Therefore, diaphoresis can help clinicians differentiate between hypoglycemic and ketoacidosis reactions.

Correct Answer: B

Rationale: Acute glomerulonephritis is an inflammatory kidney disease that typically follows a streptococcal infection, such as strep throat or skin infection caused by group A beta-hemolytic streptococcus. The infection triggers the body's immune response, leading to the deposition of immune complexes in the glomeruli of the kidneys. This results in inflammation, damage to the glomeruli, and impaired kidney function. Symptoms of acute glomerulonephritis may include hematuria (blood in the urine), proteinuria (protein in the urine), edema, hypertension, and decreased urine output. It is important to diagnose and manage acute glomerulonephritis promptly to prevent complications and promote recovery. Other answer choices do not accurately describe the typical etiology or presentation of acute glomerulonephritis.

Correct Answer: A

Rationale: The best procedure to follow if a child swallows something poisonous is to telephone the local poison control center. The experts at the poison control center can provide immediate guidance on how to handle the situation based on the specific substance ingested and the child's age and weight. They will advise whether it is necessary to bring the child to the emergency room, induce vomiting, or take other appropriate actions. Providing milk to drink to induce vomiting is not recommended as it can lead to further complications. Identifying the substance the child swallowed is important, but the first step should be to contact the poison control center for immediate assistance.

Correct Answer: A

Rationale: The first stage of the first period of reactivity in the newborn begins when the newborn awakes from a deep sleep. This stage is characterized by increased muscle tone, alertness, and interest in the environment. It typically starts about 30 minutes after birth and can last up to 2 hours. During this stage, the newborn may be restless, have an increased heart rate, and show increased vocalization. It is an important time for bonding and initial interactions with the parents, as the newborn is most alert and responsive during this period.
