A child with a poor nutritional status and weight loss is at risk for a negative nitrogen balance. To help diagnose this problem, the nurse in charge anticipates that the doctor will order which laboratory test?

Correct Answer: C

Rationale: Total protein is a laboratory test that is commonly ordered to assess the nutritional status of an individual. In the case of a child with poor nutritional status and weight loss, assessing the total protein levels can help in diagnosing a negative nitrogen balance. Total protein levels may decrease in individuals with inadequate protein intake, malnutrition, or negative nitrogen balance. Monitoring total protein levels can provide valuable information about the child's nutritional status and help guide further interventions to improve their overall health and well-being.

Correct Answer: A

Rationale: In a female child with acute post-streptococcal glomerulonephritis, the earliest sign of improvement is often seen as an increase in urine output. This occurs as the kidneys start to recover and normal functioning is restored. Increased urine output indicates improved glomerular filtration and clearance of waste products from the body. It is an essential indicator of renal function and overall improvement in the condition of the child. Other signs such as increased appetite and energy levels may follow but increased urine output is typically the first noticeable sign of improvement in cases of glomerulonephritis.

Correct Answer: D

Rationale: The correct concept that should be reinforced in the teaching plan is to systematically rotate injection sites. Rotating injection sites helps prevent lipodystrophy - changes in fat tissue due to repeated injections in the same spot. This can ensure that the insulin is properly absorbed and prevent complications. It is important for the child and their family to understand the importance of rotating injection sites to maintain good insulin absorption and reduce the risk of complications.

Correct Answer: B

Rationale: In a patient with Hirschsprung's disease presenting with fever and watery explosive diarrhea, these symptoms could indicate enterocolitis, which is a serious complication of the disease. Enterocolitis is characterized by inflammation of the intestines and can lead to significant complications if not promptly addressed. Therefore, the priority action for Nurse Joyce would be to immediately notify the physician so that appropriate interventions can be initiated promptly to manage the child's condition. Administering an antidiarrheal or monitoring the child would not be appropriate initial actions given the seriousness of the symptoms described.Ignoring these symptoms and doing nothing is also not advisable as prompt medical attention is necessary in this situation.

Correct Answer: D

Rationale: Tetralogy of Fallot is a congenital heart defect characterized by four primary abnormalities: pulmonary stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Due to the pulmonary stenosis, less blood reaches the lungs to be oxygenated, resulting in deoxygenated blood entering the systemic arterial circulation. This leads to cyanosis, which is often referred to as "Tet spells" in these patients. Cyanosis is the bluish discoloration of the skin and mucous membranes caused by the presence of deoxygenated hemoglobin. The other conditions listed do not typically result in deoxygenated blood entering the systemic arterial circulation and causing cyanosis.
