Correct Answer: C

Rationale: Phenytoin (Dilantin) is known to be incompatible with dextrose solutions (such as dextrose 5% or dextrose 5% and half-normal saline). Therefore, the nurse would plan to use normal saline solution to dilute phenytoin in order to ensure medication effectiveness and prevent any potential adverse reactions. Lactated Ringer's solution is not commonly used for diluting phenytoin as normal saline solution is the preferred choice due to compatibility considerations.

Correct Answer: A

Rationale: A first traumatic lumbar puncture is less likely to increase the risk of CNS relapse compared to other factors like T-cell leukemia or cranial nerve involvement.

Correct Answer: A

Rationale: Milk should not be given simultaneously with an oral iron supplement because calcium in milk can interfere with the absorption of iron. Calcium competes with iron for absorption in the digestive tract, thereby reducing the absorption of iron when both are taken together. It is advisable to wait at least 1-2 hours after giving the iron supplement before offering milk to ensure optimal absorption of iron. This is a common practice to improve iron absorption and prevent any potential decrease in the effectiveness of the iron supplement.

Correct Answer: D

Rationale: Speaking inhibition words like 'no' typically occurs later.
