A nurse is preparing to administer methylphenidate 25 mg PO to a school-age child who has ADHD. Available is methylphenidate 10 mg/5 mL liquid. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["12.5"]
Desired dose = 25 mg.
Available concentration = 10 mg / 5 mL.
- Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / (Available concentration (mg) / Available volume (mL))
= 25 mg / (10 mg / 5 mL)
= 25 mg × (5 mL / 10 mg)
= (25 × 5) / 10 mL
= 125 / 10 mL
= 12.5 mL.

Correct Answer is B
Explanation
A. A medication group: A medication group can help clients understand their medications, but it may not be the best for helping them adapt to the health care setting. Medication groups typically focus on pharmacological aspects rather than emotional or social adaptation.
B. A community meeting: A community meeting is an appropriate resource to help a newly admitted client adjust to the health care setting. These meetings allow clients to connect with others, learn about the structure of the facility, and share their experiences, which aids in their social and emotional adaptation.
C. A self-help meeting: Self-help meetings, such as those for addiction or mental health disorders, are useful for ongoing recovery, but they may not specifically help the client adapt to the new environment of a mental health facility.
D. A symptom-management group: While symptom-management groups can be helpful for clients to manage their mental health conditions, they do not specifically address adaptation to the healthcare setting, which is the primary need for a newly admitted client.
Correct Answer is ["B","D","E","G","H"]
Explanation
Rationale for correct choices:
- Client's recent loss: The recent death of the client's parents is a critical factor in the client's relapse into alcohol use. This significant emotional stress can exacerbate substance use and affect the client's mental and physical health, requiring close monitoring and support.
- Client's recent consumption of alcohol: The client's last drink was estimated to be 2 hours ago, and they are currently intoxicated with a blood alcohol level (BAC) of 310 mg/dL. This level is dangerously high, requiring immediate observation for signs of alcohol toxicity.
- Gastrointestinal assessment: The client reports weight loss and minimal appetite, which may be indicative of alcohol-related damage to the gastrointestinal system, such as gastritis or liver disease. This warrants a thorough assessment to address any underlying issues.
- Neurological assessment: The client is intoxicated and has slurred speech, indicating impaired neurological functioning. Additionally, alcohol use disorder can lead to long-term neurological impairments, such as cognitive deficits, which require careful monitoring during withdrawal.
- Blood alcohol level: A blood alcohol level of 310 mg/dL is critically elevated and requires urgent follow-up. This level is significantly above the normal range and indicates severe intoxication, which can lead to life-threatening complications such as respiratory depression or coma.
Rationale for incorrect choices:
- Genitourinary assessment: There are no immediate concerns related to the client's genitourinary system based on the provided information. The client did not report any issues or symptoms in this area.
- Smoking history: Although smoking history is important in overall health assessments, the client's current concerns (alcohol use disorder, recent loss, intoxication) take priority over the 20 years ago smoking history in this situation.
- Respiratory assessment: The client's respiratory rate is 10/min, which is low but not immediately alarming in the context of alcohol intoxication. Close monitoring is required, but there is no urgent indication of respiratory distress at this time. The client ‘s respiratory examination is normal as well as SPO2.
- Cardiac assessment: The client's heart rate and blood pressure are within normal limits, and there is no indication of acute cardiac distress. Therefore, a cardiac assessment does not require immediate follow-up unless other symptoms develop.
