A client at 8 weeks' gestation has been advised to have the embryo undergo genetic testing. The nurse will instruct the client that the area of the embryo being tested will be the:
 
  1. Endometrium.
   2. Ectoderm.
   3. Chorion.
   4. Amnion.

Question 2

The client is admitted to the acute care unit with a phosphorus level of 2.3 mg/dL. Which nursing intervention would support this client's homeostasis?
 
  1. Encourage consumption of milk and yogurt
   2. Enforce strict isolation protocols
   3. Encourage consumption of a high-calorie carbohydrate diet
   4. Strain all urine

Answer to Question 1

3. Chorion.

Rationale:
The chorion is the outermost embryonic membrane and develops into chorionic villi, which can be used for early genetic testing of the embryo at 8 to 11 weeks' gestation by chorionic villi sampling. The endometrium is the lining of the uterus and will not be used for genetic testing of the embryo. The ectoderm is a germ layer and will develop into specific structures within the developing fetus. The amnion will develop into amniotic fluid, which can also be sampled for genetic testing but may not be developed by 8 weeks; gestation.

Answer to Question 2

1. Encourage consumption of milk and yogurt

Rationale:
A phosphorus level of 2.3 is low, and the client needs additional phosphorus. Provision of phosphorus-rich foods such as milk and yogurt is a good way to provide that additional phosphorus. There is no indication of the need to place this client in strict isolation, to increase the client's carbohydrate calorie intake, or to strain all urine.
