The nurse is preparing an intravenous infusion of phenytoin (Dilantin) as prescribed by the physician for the client with seizures. Which of the following solutions will the nurse plan to use to dilute this medication?
- A. Dextrose 5%
- B. Lactated Ringer's solution
- C. Normal saline solution
- D. Dextrose 5% and half-normal saline (0.45%)
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.
Lily , age 5, with an intelligence quotient of 65 is admitted to the hospital for evaluation. When planning care, the nurse should keep in mind that this child is:
- A. Within the lower range of normal intelligence
- B. Mildly retarded but educable
- C. Moderately retarded but trainable
- D. Completely dependent on others for care
Correct Answer: C
Rationale: Lily, with an intelligence quotient of 65, falls into the category of moderate intellectual disability, which typically ranges from IQ 35-49 to 50-69. Children with moderate intellectual disability have limitations in intellectual functioning that result in difficulties with adaptive behaviors, learning, and social skills. They can benefit from training, therapies, and educational interventions to improve their functional abilities and quality of life. While they may require support and supervision in various aspects of daily living, they are not completely dependent on others for care like individuals with severe or profound intellectual disability. Therefore, the nurse should consider Lily as moderately retarded but trainable when planning care for her in the hospital.
