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 C
Explanation
A. Call security guards to the scene for a show of force: Calling security may escalate the situation, especially if the client is already showing signs of agitation. This could increase fear or aggression, making it harder to de-escalate the client. A calm and supportive approach is more effective.
B. Escort the client to a secluded area to speak privately: Escorting the client to a secluded area may increase feelings of isolation or entrapment, potentially worsening the situation. It is better to maintain an open, non-threatening environment for communication and de-escalation.
C. Offer the client several options for a time-out period: Offering choices, such as a time-out, helps the client feel some control over the situation, which can reduce agitation. This strategy fosters cooperation while addressing the need for the client to calm down in a safe space.
D. Place the client in restraints before they escalate further: Restraints should be a last resort and only used if the client poses an immediate danger to themselves or others. Using restraints prematurely can increase aggression and escalate the situation, so other de-escalation techniques should be tried first.
Correct Answer is ["C","E","H"]
Explanation
Rationale for correct choices:
- Ask the client if they have been hit, slapped, or kicked within the past year: This question is specific and nonjudgmental, helping the client disclose abusive behaviors without feeling pressured. It's important for identifying signs of abuse that may not be immediately obvious.
- Ask the client to clarify the circumstances of their injuries: Clarifying the circumstances of the injuries helps the nurse assess the situation and detect any discrepancies in the explanation that may suggest abuse. It can also guide the next steps in care and safety planning.
- Discuss with the client the factors that precipitate violence: Identifying triggers and patterns of violence empowers the client to recognize and avoid dangerous situations, and to plan for their safety moving forward.
Rationale for incorrect choices:
- Interview the client with another nurse present: The primary goal during is to establish a private and trusting environment where the client feels safe to disclose. The presence of another person can make a client feel less comfortable and less likely to speak openly about sensitive issues like intimate partner violence.
- Ask questions in different ways until the client provides an answer: Repeating or rephrasing questions multiple times could make the client feel pressured or coerced, which may hinder trust and open communication. It’s important to respect their pace and comfort level.
- Refrain from asking the client if they are afraid of their partner: Fear of the partner is a crucial indicator of abuse, and not asking about it may prevent the client from disclosing important information. Acknowledging fear helps assess the level of risk and urgency.
- Assure the client that their medical team feels sympathy for their injuries and disapproval for the person responsible for inflicting them: While empathy is important, making value judgments about the abuser can undermine the client's trust, making them feel judged or unsupported in their decisions.
- Inform the client that they should have fought back: Telling the client what they "should have done" may inadvertently place blame on them and discourage further disclosures. It’s vital to maintain a supportive, nonjudgmental stance to ensure the client feels safe.
