A nurse is assisting with the admission of a child who has measles. Which of the following isolation precautions should the nurse initiate?

Choice A reason: This choice is incorrect because limiting intake of high-protein foods is not a method of preventing iron deficiency anemia. High-protein foods are foods that contain a large amount of protein, such as meat, poultry, fish, eggs, dairy products, beans, nuts, or seeds. Protein is a nutrient that helps to build and repair body tissues and support immune function. It may also provide iron, which is a mineral that helps to produce hemoglobin, the protein that carries oxygen in red blood cells. Therefore, limiting intake of high-protein foods may reduce iron intake and increase the risk of iron deficiency anemia.

Choice B reason: This choice is correct because mom should continue prenatal vitamins if breastfeeding or formula with an iron supplement is a method of preventing iron deficiency anemia. Prenatal vitamins are supplements that contain various vitamins and minerals that are essential for pregnant or lactating women and their babies. They may include iron, which helps to prevent maternal and infant anemia. Formula with an iron supplement is a type of infant formula that contains added iron to meet the nutritional needs of infants who are not breastfed or partially breastfed. Therefore, mom should continue prenatal vitamins if breastfeeding or formula with an iron supplement can help to provide adequate iron intake and prevent iron deficiency anemia.

Choice C reason: This choice is incorrect because administering fat-soluble vitamins daily is not a method of preventing iron deficiency anemia. Fat-soluble vitamins are vitamins that dissolve in fat and can be stored in the body, such as vitamins A, D, E, and K. They have various functions such as maintaining vision, bone health, skin health, and blood clotting. They do not have a direct role in preventing iron deficiency anemia.

Choice D reason: This choice is incorrect because including fluoridated water in the toddler's diet is not a method of preventing iron deficiency anemia. Fluoridated water is water that contains fluoride, which is a substance that helps to prevent tooth decay and cavities. It does not have a direct role in preventing iron deficiency anemia.

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.
