A nurse is planning care for a newborn who has hyperbilirubinemia and is receiving phototherapy.

Which of the following interventions should the nurse include in the plan?

This is because phototherapy can cause dehydration and increase insensible water loss, so covering the genitalia can prevent excessive fluid loss and maintain thermoregulation.

Some possible explanations for the other choices are:

• Choice A is wrong because monitoring skin temperature every hour is not enough to prevent hyperthermia or hypothermia during phototherapy.The skin temperature should be monitored continuously or at least every 15 minutes.

• Choice C is wrong because repositioning newborn every 4 hours is not frequent enough to prevent pressure ulcers, skin breakdown, or eye damage from the light source.The newborn should be repositioned at least every 2 hours.

• Choice D is wrong because encouraging parent-infant interaction as tolerated is not a specific intervention for phototherapy.

While parent-infant interaction is important for bonding and development, it should not interfere with the effectiveness of phototherapy.The newborn should be exposed to the light as much as possible, except for feeding and diaper changes.

Normal ranges for serum bilirubin levels vary depending on the age, gestational age, and risk factors of the newborn.Generally, the levels should be below 5 mg/dL for term infants and below 7 mg/dL for preterm infants by the fifth day of life.

These are normal inflammatory responses to the vaccine.

The tetanus vaccine protects people from the bacteria that cause tetanus, a serious disease that causes muscle stiffness and spasms.

The vaccine stimulates the body’s immune system to produce antibodies against the bacteria.Sometimes, this immune response can cause mild symptoms such as pain, redness, swelling, fever, headache, or tiredness.

These are not signs of an infection or an allergic reaction, but rather the body’s way of building immunity.

Choice A is wrong because an allergic reaction to the vaccine would cause more severe symptoms such as hives, swelling of the face or throat, difficulty breathing, or shock.

These symptoms would usually occur within minutes or hours of getting the vaccine and require immediate medical attention.

Choice C is wrong because these are not signs of an active infection with tetanus.

Tetanus is a rare but potentially fatal disease that causes muscle spasms and paralysis.

It is caused by bacteria that enter the body through wounds or cuts.The symptoms of tetanus usually appear several days or weeks after exposure and include lockjaw, stiffness of the neck and abdomen, difficulty swallowing, fever, sweating, and seizures.

The tetanus vaccine prevents the disease by creating immunity before exposure.

Choice D is wrong because these are not adverse effects of preservatives in the vaccine.

Preservatives are substances that prevent contamination and spoilage of vaccines.The most common preservative used in tetanus vaccines is thimerosal, a mercury-based compound that has been proven to be safe and effective.

There is no evidence that thimerosal causes autism or any other health problems.

Some people may have a sensitivity to thimerosal or other ingredients in the vaccine, but this is very rare and would cause an allergic reaction as described in choice A.
