A nurse is teaching the parents of a child who has ADHD about methylphenidate. Which of the following statements should the nurse include in the teaching?
This medication might increase the amount of saliva your child produces.
Administer the medication at bedtime.
Your child might gain weight while taking this medication.
Restrict your child’s intake of caffeine while she is taking this medication.
The Correct Answer is D
The correct answer is d. Restrict your child’s intake of caffeine while she is taking this medication.
Choice A Reason:
This statement is incorrect. Methylphenidate does not typically increase saliva production. In fact, it is more commonly associated with dry mouth as a side effect. Therefore, informing parents that the medication might increase saliva production would be misleading and not based on the known side effects of the drug.
Choice B Reason:
This statement is incorrect. Methylphenidate should generally be administered in the morning or early afternoon to avoid insomnia, as it is a stimulant and can interfere with sleep if taken too late in the day. Administering the medication at bedtime would likely cause sleep disturbances, which is counterproductive for managing ADHD symptoms.
Choice C Reason:
This statement is incorrect. Methylphenidate is more commonly associated with weight loss rather than weight gain. The medication can suppress appetite, leading to reduced food intake and potential weight loss. Therefore, it is important to monitor the child’s weight and nutritional intake while on the medication, but weight gain is not a typical concern.
Choice D Reason:
This statement is correct. Caffeine is a stimulant and can exacerbate the side effects of methylphenidate, such as increased heart rate, jitteriness, and anxiety. Therefore, it is advisable to restrict the child’s intake of caffeine while taking this medication to avoid these potential interactions and side effects. This includes limiting consumption of caffeinated beverages like coffee, tea, and certain sodas.

Correct Answer is D
Explanation
d. Do not reduce normal dietary sodium intake.
Explanation of Choices
Choice A Reason: Limit Fluid Intake to 1,000 mL of Fluid per Day
Limiting fluid intake to 1,000 mL per day is not recommended for clients taking lithium carbonate. Adequate hydration is crucial because lithium can affect kidney function and fluid balance. Dehydration can increase lithium levels in the blood, leading to toxicity. Therefore, clients should maintain normal fluid intake to ensure proper hydration and avoid complications.
Choice B Reason: Adjust the Dose if You Feel Out of Control
Clients should never adjust their lithium dose on their own. Lithium has a narrow therapeutic range, meaning the difference between an effective dose and a toxic dose is small. Any changes in dosage should be made under the supervision of a healthcare provider to avoid the risk of lithium toxicity or subtherapeutic levels. Self-adjusting the dose can lead to serious health risks.
Choice C Reason: Have Serum Lithium Levels Checked Every 6 Months
While regular monitoring of serum lithium levels is essential, checking levels every 6 months may not be sufficient. Initially, serum lithium levels should be checked more frequently, such as every 1 to 2 weeks, until stable therapeutic levels are achieved. After stabilization, levels are typically monitored every 3 to 6 months, depending on the patient’s clinical status and any changes in medication or health condition. Regular monitoring helps ensure the medication remains within the therapeutic range and prevents toxicity.
Choice D Reason: Do Not Reduce Normal Dietary Sodium Intake
Maintaining normal dietary sodium intake is crucial for clients taking lithium. Sodium levels in the body can affect lithium levels; a decrease in sodium intake can lead to higher lithium levels and increase the risk of toxicity. Conversely, an increase in sodium intake can lower lithium levels, reducing its effectiveness. Therefore, clients should be advised to maintain a consistent sodium intake to help stabilize lithium levels in the blood.
Correct Answer is ["10.5"]
Explanation
Step 1: Determine the concentration of insulin in the IV bag. 100 units of insulin are added to 150 mL of normal saline.
100 units ÷ 150 mL = (100 ÷ 150) = 0.6667 units per mL Result: 0.6667 units per mL
Step 2: Calculate the rate in mL per hour needed to deliver 7 units per hour. 7 units per hour ÷ 0.6667 units per mL = (7 ÷ 0.6667) = 10.5 mL per hour Result: 10.5 mL per hour
The correct rate for the nurse to set the IV pump is 10.5 mL per hour.
