A nurse in a pediatric clinic is caring for a child who has iron deficiency anemia and a new prescription for ferrous sulfate tablets. Which of the following instructions should the nurse provide the parents regarding the administration of this medication?

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: Polyuria is not a finding of nephrotic syndrome, but rather a finding of diabetes mellitus or diabetes insipidus. Polyuria means excessive urination, which can cause dehydration and electrolyte imbalance.

Choice B: Smoky brown urine is not a finding of nephrotic syndrome, but rather a finding of acute glomerulonephritis or hemolytic uremic syndrome. Smoky brown urine means that there is blood in the urine, which can indicate damage to the glomeruli, the filtering units of the kidneys.

Choice C: Hypertension is not a finding of nephrotic syndrome, but rather a finding of chronic kidney disease or renal artery stenosis. Hypertension means high blood pressure, which can cause damage to the blood vessels and organs.

Choice D: Facial edema is a common finding of nephrotic syndrome, as nephrotic syndrome is a condition in which the kidneys leak large amounts of protein into the urine, causing low blood protein levels and fluid retention. Facial edema means swelling of the face, especially around the eyes, which can occur due to gravity and fluid shifts.
