A nurse is preparing to administer lansoprazole 30 mg PO daily to a client. The amount available is lansoprazole 10 mg per tablet. How many tablets should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Free T4

In primary hypothyroidism, the thyroid gland is underactive and does not produce enough thyroid hormones. As a result, free T4 levels are typically low, not elevated. Free T4 is a direct measure of the active thyroid hormone available in the blood. Therefore, an elevation in free T4 is not expected in primary hypothyroidism.

Choice B reason: Thyroid-stimulating hormone (TSH)

Thyroid-stimulating hormone (TSH) is elevated in primary hypothyroidism due to the lack of negative feedback from low thyroid hormone levels. The pituitary gland produces more TSH in an attempt to stimulate the thyroid gland to produce more hormones. This is a hallmark finding in primary hypothyroidism and is used as a key diagnostic indicator.

Choice C reason: Serum T3

Serum T3 levels can be variable in primary hypothyroidism. While they may be low, they are often maintained within the normal range until the condition becomes severe. This is because T3 is produced in smaller quantities and has a shorter half-life compared to T4. Therefore, an elevation in serum T3 is not typically seen in primary hypothyroidism.

Choice D reason: Serum T4

Similar to free T4, serum T4 levels are usually low in primary hypothyroidism. The thyroid gland’s reduced ability to produce thyroid hormones results in decreased levels of both free and total T4. Thus, an elevation in serum T4 is not expected in primary hypothyroidism.

Choice A reason:

Washing the cord daily with mild soap and water is not recommended. The best practice is to keep the umbilical cord stump clean and dry. Cleaning it with water and mild soap can be done if it gets dirty, but it should not be a daily routine as it might delay the drying process.

Choice B reason:

Applying petroleum jelly to the cord stump is not advised. The goal is to keep the stump dry to promote natural drying and falling off. Petroleum jelly can keep the area moist, which is counterproductive to the drying process.

Choice C reason:

Covering the cord with the diaper is not recommended. Instead, the diaper should be folded down below the umbilical cord stump to keep it exposed to air and prevent irritation from urine or stool3. This helps the stump to dry out and fall off naturally.

Choice D reason:

Giving a sponge bath until the cord stump falls off is the correct instruction. Submerging the baby in water can delay the drying and falling off of the stump. Sponge baths help keep the area dry and clean, promoting faster healing.
