A nurse is teaching a newly licensed nurse about the uses of ultrasonography in the first trimester of pregnancy. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

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.

The correct answer is **Choice C: A client who has salicylate intoxication.**

Choice A rationale:

A client taking a thiazide diuretic is at risk for metabolic alkalosis, not metabolic acidosis. Thiazide diuretics can cause a loss of potassium and chloride, leading to a relative increase in bicarbonate and a higher pH, resulting in metabolic alkalosis.

Choice B rationale:

A client who is vomiting is at risk for metabolic alkalosis, not metabolic acidosis. Vomiting leads to a loss of gastric acid (hydrochloric acid), resulting in a relative increase in bicarbonate and a higher pH, leading to metabolic alkalosis.

Choice C rationale:

A client with salicylate intoxication is at risk for metabolic acidosis. Salicylates, the active ingredient in aspirin, can cause an increased production of organic acids, leading to a decrease in pH and the development of metabolic acidosis.

Choice D rationale:

A client with hypoventilation is at risk for respiratory acidosis, not metabolic acidosis. Hypoventilation leads to a buildup of carbon dioxide, which dissolves in the blood to form carbonic acid, resulting in a decrease in pH and respiratory acidosis.
