A nurse is preparing to administer midazolam 0.2 mg/kg via IV bolus now. The client weighs 220 lb. How many mg should the nurse administer?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Dilute the medication with sterile water before injecting: Phenytoin should not be diluted before administration because it may cause precipitation or crystallization of the drug, leading to potential adverse effects such as tissue irritation or embolism.

B. Administer the medication over 1 min: Phenytoin should be administered slowly over 1 to 2 minutes to reduce the risk of adverse effects such as hypotension or cardiac arrhythmias. Rapid infusion can lead to cardiovascular collapse.

C. Slow the injection if the medication crystallizes: If the medication crystallizes, the nurse should stop the injection immediately and flush the IV line with normal saline. However, preventing crystallization by administering the medication slowly over the recommended time is preferable.

D. Follow the IV injection with sterile water: Following the IV injection with sterile water is not a standard practice for administering phenytoin. Instead, the nurse should follow institutional guidelines for flushing the IV line after medication administration, typically with normal saline.

A. The client drinks 2 liters of liquids daily. - This statement indicates adequate fluid intake, which is important for preventing dehydration and lithium toxicity. Increased fluid intake helps maintain normal lithium levels by promoting its excretion through urine.

B. The client eats 2 to 3 gm of sodium-containing foods daily. - This statement suggests a moderate sodium intake, which can help maintain stable lithium levels. Adequate sodium intake is important for preventing lithium toxicity because sodium depletion can increase lithium reabsorption by the kidneys, leading to higher serum levels.

C. The client runs 4 miles outdoors every afternoon. - This statement indicates excessive sweating, which can lead to dehydration and subsequent lithium toxicity. Vigorous exercise, particularly in hot environments, increases fluid loss through sweating, potentially reducing lithium excretion and increasing serum levels.

D. The client eats foods high in tyramine. - This statement is unrelated to lithium toxicity. Tyramine-containing foods are typically associated with interactions with monoamine oxidase inhibitors (MAOIs), not lithium.
