A nurse is planning care for a preschooler who has leukemia. After reviewing the child's information, which of the following potential issues should the nurse identify that the child is at risk for developing? (Select all that apply.)

Choice A reason: Administering antibiotic therapy is an anticipated prescription for the client, as it can treat the possible bacterial infection that is causing the fever, anorexia, and shortness of breath. The client may have developed infective endocarditis, a serious condition that affects the heart valves and can lead to heart failure or stroke. Antibiotic therapy can help prevent further complications and reduce the risk of mortality.

Choice B reason: Obtaining an echocardiogram is an anticipated prescription for the client, as it can help diagnose the presence and severity of infective endocarditis. An echocardiogram is a noninvasive test that uses sound waves to create images of the heart and its structures. It can show if there is any damage to the heart valves, vegetation (clumps of bacteria and cells) on the valves, or signs of heart failure.

Choice C reason: Obtaining blood cultures x3 is an anticipated prescription for the client, as it can help identify the causative organism of the infection and guide the appropriate antibiotic therapy. Blood cultures are samples of blood that are taken from different sites and times and tested for the presence of bacteria or other microorganisms. They can confirm the diagnosis of infective endocarditis and determine the sensitivity and resistance of the bacteria to different antibiotics.

Choice D reason: Restricting dental hygiene is a contraindicated prescription for the client, as it can worsen the oral health and increase the risk of infection. Dental hygiene is important for preventing plaque and tartar buildup, which can harbor bacteria and cause dental caries, gingivitis, or periodontitis. These conditions can increase the risk of bacteremia (bacteria in the blood) and infective endocarditis. The nurse should teach the client to maintain good oral hygiene and use a soft-bristled toothbrush and gentle flossing.

Choice E reason: Performing a strenuous exercise regimen twice a day is a contraindicated prescription for the client, as it can increase the cardiac workload and exacerbate the symptoms of infective endocarditis. Strenuous exercise can cause tachycardia (fast heart rate), dyspnea (difficulty breathing), chest pain, and fatigue, which can worsen the condition of the heart and the valves. The nurse should advise the client to avoid strenuous exercise and limit physical activity to a level that does not cause symptoms.

Choice A reason: Nephritic syndrome is a kidney disorder that causes inflammation and damage to the glomeruli, the filtering units of the kidneys. It can cause hematuria (blood in the urine), proteinuria (protein in the urine), hypertension (high blood pressure), and edema (swelling). However, it does not cause a palpable abdominal mass, which is a characteristic sign of Wilms tumor.

Choice B reason: Wilms tumor is a malignant tumor of the kidney that occurs mainly in children under 5 years of age. It can cause a large, firm, and painless abdominal mass, hematuria, abdominal pain, fever, and hypertension. It is the most common renal tumor in children and requires prompt diagnosis and treatment.

Choice C reason: Pyloric stenosis is a condition that causes narrowing of the pylorus, the outlet of the stomach. It can cause projectile vomiting, dehydration, weight loss, and a palpable olive-shaped mass in the upper abdomen. However, it does not cause hematuria or a large abdominal mass.

Choice D reason: Intussusception is a condition that occurs when a part of the intestine slides into another part, causing a blockage. It can cause abdominal pain, vomiting, bloody stools, and a sausage-shaped mass in the abdomen. However, it does not cause hematuria or a large abdominal mass.
