A nurse is providing teaching about self-administration of insulin to the parent of a school-age child who has a new diagnosis of diabetes mellitus. Which of the following statements by the parent indicates a need for further teaching?

Choice A: Clubbing of the nail beds is not a finding that the nurse should expect in a child who has aortic stenosis, which is a condition that causes narrowing of the aortic valve and obstructs blood flow from the left ventricle to the aorta. Clubbing of the nail beds is a sign of chronic hypoxia, which can occur in conditions that affect the lungs or the right side of the heart.

Choice B: Murmur is a finding that the nurse should expect in a child who has aortic stenosis, as it indicates turbulent blood flow through the narrowed valve. A murmur can be heard with a stethoscope over the chest and may vary in intensity, pitch, and duration. A murmur caused by aortic stenosis is typically systolic, loud, and harsh and radiates to the neck or back.

Choice C: Weak pulses are a finding that the nurse should expect in a child who has aortic stenosis, as they indicate reduced blood flow and pressure in the peripheral arteries. Weak pulses can be felt with palpation of the radial, brachial, femoral, or pedal arteries and may be difficult to detect or absent.

Choice D: Bradycardia is not a finding that the nurse should expect in a child who has aortic stenosis, as it indicates a slow heart rate, which is less than 60 beats per minute in children. Bradycardia can occur in conditions that affect the electrical conduction system of the heart or cause increased vagal tone. A child who has aortic stenosis may have tachycardia, which is a fast heart rate, as a compensatory mechanism to increase cardiac output.

Choice E:Hypertension is not typically associated with aortic stenosis in children; instead, the condition often results in reduced blood pressure distal to the valve.

Choice A reason: This choice is incorrect because a regular diet, no added salt may not be sufficient to prevent fluid retention and hypertension in a child who has acute glomerulonephritis. Acute glomerulonephritis is an inflammation of the glomeruli, which are the tiny blood vessels that filter blood in the kidneys. It may cause symptoms such as hematuria, proteinuria, oliguria, edema, or hypertension. Therefore, avoiding salt alone may not reduce sodium and water intake and excretion.

Choice B reason: This choice is incorrect because a low-protein, low-potassium diet may not be necessary for a child who has acute glomerulonephritis. A low-protein, low-potassium diet may be indicated for a child who has chronic kidney disease or end-stage renal disease, which can cause uremia, hyperkalemia, or metabolic acidosis. However, in acute glomerulonephritis, the kidney function usually recovers within weeks or months, and the protein and potassium levels are not significantly affected.

Choice C reason: This choice is incorrect because a low-carbohydrate, low-protein diet may not be appropriate for a child who has acute glomerulonephritis. A low-carbohydrate, low-protein diet may be used for a child who has diabetes mellitus or ketosis-prone epilepsy, which can cause hyperglycemia or ketone production. However, in acute glomerulonephritis, carbohydrate metabolism is not impaired, and the protein intake should be adequate to prevent malnutrition and promote healing.

Choice D reason: This choice is correct because a low-sodium, fluid-restricted diet is an appropriate diet for a child who has acute glomerulonephritis. A low-sodium, fluid-restricted diet helps to reduce the fluid retention and hypertension by limiting the sodium and water intake and excretion. The sodium intake should be less than 2 g per day, and the fluid intake should be equal to the urine output plus 500 mL per day.
