A client has flushed skin, bulging eyes and perspiration, and states that he has been "irritable" and having palpitations. The nurse interprets these findings as suggesting:

A. Push IV potassium: Potassium should be administered slowly and with caution, as administering potassium too rapidly can cause cardiac arrhythmias. Potassium should only be given according to specific protocols and after monitoring serum potassium levels.

B. Administer intravenous potassium: In diabetic ketoacidosis (DKA), potassium levels often decrease due to insulin therapy, which shifts potassium into cells. Intravenous potassium is often required to replace lost potassium and prevent dangerous complications.

C. Assess fluid volume status: In DKA, the client experiences significant fluid loss due to polyuria (frequent urination) and dehydration. It is important to closely monitor the client’s fluid volume status and correct it with intravenous fluids, typically normal saline.

D. Check for urinary ketones: Urinary ketones are a key marker in diagnosing DKA. The nurse should monitor for the presence of ketones in the urine as it helps assess the degree of ketosis and the effectiveness of treatment.

E. Maintain adequate ventilation: In DKA, respiratory compensation (such as Kussmaul breathing) is common as the body attempts to correct acidosis. Adequate ventilation should be ensured to support the respiratory system and correct the metabolic acidosis.

A. "Eat foods high in vitamins such as apples, pears, and oranges.": There is no specific dietary restriction related to vitamins following radioactive iodine therapy. The primary focus should be on radiation precautions and post-treatment care, not on specific food choices.

B. "Wash your clothing separate from others in the household.": Sarah should wash her clothes separately from others to minimize exposure to radiation. Radioactive iodine can be excreted in sweat, and separation helps reduce exposure to family members.

C. "Do not share utensils, plates, and cups with anyone else.": After receiving radioactive iodine therapy, Sarah should avoid sharing utensils, plates, and cups to limit potential exposure to radioactive material. This helps reduce the risk of radiation contamination.

D. "You can play with your children for 1 hour each day.": Direct contact with others, especially children, should be minimized after radioactive iodine therapy. Sarah should avoid close contact with children and others to minimize exposure to radiation.

E. "Flush the toilet at least 3 times after each use.": To reduce radiation exposure, Sarah should flush the toilet at least three times after each use to ensure that radioactive iodine is effectively cleared from the system. This helps prevent contamination of shared bathroom areas.
