A nurse is providing prenatal teaching to a client who practices a vegan diet and is trying to increase her intake of vitamin B12. Which of the following foods should the nurse recommend?

Choice A rationale:
Placing the client in a Trendelenburg position (head down and feet up) is not recommended after a convulsion in a pregnant client. It could potentially compromise blood flow to the brain and fetus. The priority after a convulsion is to ensure the client's airway and oxygenation.

Choice B rationale:
Assisting the client to void might be necessary during the course of care but is not the immediate action needed after a convulsion. The priority is to address airway and oxygenation needs.

Choice C rationale:
Administering oxygen to the client via face mask at 10 L/min is the correct action after the client experiences a convulsion. Eclampsia is a severe complication of preeclampsia, characterized by seizures. Providing oxygen ensures adequate oxygenation to the brain and vital organs during and after the convulsion.

Choice D rationale:
Giving calcium gluconate is not the appropriate action for eclampsia. Calcium gluconate is used to treat hyperkalemia and calcium channel blocker overdose. It does not address the underlying issue of eclampsia or prevent further convulsions. The immediate focus should be on managing the convulsions and ensuring the client's safety and well-being.

Choice A rationale:

Determining gestational age in the first trimester is a common and important use of ultrasound. It helps confirm the estimated due date and monitor the fetus's growth and development.

Choice B rationale:

Performing a biophysical profile in the first trimester is not a common use of ultrasound. Biophysical profiles are usually performed in the second or third trimester to assess fetal well-being.

Choice C rationale:

Observing placental maturity in the first trimester is not a standard use of ultrasound. Placental maturity is typically assessed later in pregnancy, especially in the third trimester.

Choice D rationale:

Detecting intrauterine growth restriction in the first trimester is not a primary use of ultrasound. Intrauterine growth restriction is more commonly assessed in the later stages of pregnancy when fetal growth is a concern.
