A nurse is helping to place a client into the prone position.
The nurse should use a small pillow to relieve pressure from which of the following areas of the client's body?

Choice A rationale:

The administration of Rh(D) immune globulin (RhoGAM) is typically indicated for Rh-negative mothers who are carrying Rh-positive fetuses to prevent sensitization to Rh antigens. It is not directly related to the amniocentesis procedure. Therefore, this information is not necessary for the client undergoing an amniocentesis.

Choice B rationale:

This is the correct answer. Having an empty bladder is crucial during an amniocentesis procedure because a full bladder can obscure visualization of the fetus and the needle placement. It is essential for a successful and safe procedure. The nurse should instruct the client to empty their bladder before the test.

Choice C rationale:

The position during an amniocentesis is typically dorsal recumbent or semi-Fowler's position to allow for proper visualization of the fetus and needle placement. Lying on the left side is not a standard position for this procedure, so this information is incorrect and not necessary for the client.

Choice D rationale:

Drinking 50 grams of oral glucose is not a requirement for an amniocentesis procedure. This information is unrelated to the amniocentesis and can be confusing for the client. Therefore, it is not necessary to include this in the instructions.

Choice B rationale:

Prothrombin time. Monitoring prothrombin time is not typically required for clients taking levothyroxine. Prothrombin time is a measure of blood clotting and is not directly affected by thyroid hormone replacement therapy.

Choice C rationale:

Blood urea nitrogen. Monitoring blood urea nitrogen is not specifically related to levothyroxine therapy. Blood urea nitrogen is a measure of kidney function and is not typically affected by thyroid hormone replacement.

Choice D rationale:

Serum potassium. Monitoring serum potassium levels is important for some medications, but it is not a primary concern when a client is taking levothyroxine. Levothyroxine is primarily used to replace or supplement thyroid hormones, and its main focus is on thyroid function.

Choice A rationale:

Triiodothyronine. Triiodothyronine (T3) is one of the thyroid hormones, and monitoring its levels is essential when a client is taking levothyroxine. Levothyroxine is a synthetic form of thyroxine (T4), which the body converts into triiodothyronine (T3) Monitoring T3 levels helps ensure that the client's thyroid hormone replacement therapy is effective and that they are not experiencing over- or under-dosage.
