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 tying colorful latex balloons to the side of
the crib may pose a risk of choking or suffocation for the infant who is in a cast for DDH. Latex balloons are made of rubber that can break easily and form small pieces that can block the airway or lungs if swallowed or inhaled by
the infant. Therefore, avoiding latex products such as balloons, gloves, or bandages is important to prevent accidents or injuries.

Choice B reason: This choice is incorrect because following the doctor's instructions regarding activities and treatment plans is not a specific strategy to promote the infant's growth and development. Following
the doctor's instructions regarding activities and treatment plans is a general responsibility of the nurse that applies to any client who has any condition or procedure. It may help to ensure the safety and effectiveness of the care, but it does not address the developmental needs of the infant who is in a cast for DDH.

Choice C reason: This choice is correct because providing a small electronic toy is a specific strategy to promote
the infant's growth and development. Providing a small electronic toy can help stimulate the infant's senses, cognition, and motor skills by offering visual, auditory, or tactile feedback. It may also help to reduce boredom, frustration, or depression by providing entertainment, diversion, or comfort. Therefore, providing a small electronic toy can help to enhance the developmental outcomes of the infant who is in a cast for DDH.

Choice D reason: This choice is incorrect because changing the infant's diaper as soon as soiling occurs is not a specific strategy to promote the infant's growth and development. Changing the infant's diaper as soon as soiling occurs is a general hygiene measure that applies to any infant who wears a diaper. It may help to prevent skin irritation, infection, or odor by keeping the diaper area clean and dry, but it does not address the developmental needs of the infant who is in a cast for DDH.

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.
