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. "We will help get you through this. You'll be fine.": While this statement may be meant to comfort, it dismisses the client's feelings and doesn't address the possibility of immediate harm or crisis. It’s important to validate the client’s emotions and assess for safety.
B. "What have you done to change your situation?": This response can come across as accusatory or judgmental, which may not be helpful in a crisis situation. It’s important to be supportive and nonjudgmental rather than questioning the client’s actions.
C. "Are you thinking about harming yourself?": The client's statement indicates feelings of hopelessness, which could signal suicidal ideation. Directly asking about self-harm or suicide helps assess the client's safety and provides an opportunity to intervene if necessary.
D. "You should remove yourself from this situation now.": While suggesting safety is important, this statement may feel too directive or overwhelming. The nurse should assess the client’s readiness for action and help them explore their options in a supportive way.
Correct Answer is A
Explanation
A. The nurse has witnessed the client's signature on the form: The nurse’s signature indicates they witnessed the client voluntarily sign the consent form. The nurse does not provide information but confirms that the client signed without coercion.
B. The nurse has assessed the client's knowledge of alternative treatments: Assessing the client’s knowledge of alternatives is typically the provider’s responsibility, not the nurse’s. The nurse’s role is to ensure that the client signed the form voluntarily.
C. The nurse has discussed the risks of ECT with the client: Discussing risks is the provider’s responsibility. The nurse’s role is to observe that the client is signing the form after receiving adequate explanation of risks from the provider.
D. The nurse has provided information about the benefits of ECT: Providing information on benefits is the provider’s role. The nurse can clarify any doubts, but the provider must explain the benefits of the treatment before consent is given.
