A nurse is admitting a child who has pertussis. Which of the following transmission-based precautions should the nurse initiate?

Choice A reason: Introducing popcorn as a healthy snack at 12 months of age is not recommended due to the risk of choking. Popcorn is a choking hazard for young children and should be avoided until they are older.

Choice B reason: Providing 36 oz of milk per day to a toddler may be excessive and can lead to iron deficiency anemia due to the displacement of other iron-rich foods. The American Academy of Pediatrics recommends 16-24 oz of milk per day for toddlers.

Choice C reason: Offering 8 to 10 oz of juice per day to a preschooler exceeds the American Academy of Pediatrics' recommendation of limiting juice to 4-6 oz per day for children 1-6 years old to prevent dental caries and ensure they consume more whole fruits.

Choice D reason: Encouraging a 15-year-old to increase calcium intake is appropriate as adolescence is a critical period for bone development. Adequate calcium intake supports optimal bone growth and density, helping to prevent osteoporosis later in life.

Choice A reason: Assessing vital signs every 4 hours is important, but it is not specific to the care of an infant post-cardiac catheterization. Vital signs should be monitored according to the infant's condition and hospital policy.

Choice B reason: Monitoring the color of the affected extremity is crucial after cardiac catheterization to ensure there is no compromise in blood flow, which could indicate a vascular injury or thrombosis at the catheterization site.

Choice C reason: Maintaining NPO (nothing by mouth) status for 8 hours may be necessary before the procedure, but post-catheterization care typically includes gradual reintroduction of fluids and then food as tolerated.

Choice D reason: Keeping the affected extremity flexed is not recommended post-cardiac catheterization. The limb should be kept straight to avoid bending at the catheterization site, which could lead to bleeding or clot formation.
