A patient requires an IV infusion of a psychotropic medication at a dose of 0.5 mg/kg/hr. The medication is supplied in vials of 2 mg/ml. If the patient weighs 70 kg, how many milliliters of medication should be administered per hour?
25 mL/hr
17.5 mL/hr
35 mL/hr
8 mL/hr
The Correct Answer is B
A. This value does not correspond to the math required for this problem. It may result from using an incorrect weight or an incorrect concentration (e.g., assuming 1.4 mg/mL instead of 2 mg/mL).
B. Step 1: Calculate the dose in mg/hr. Dose (mg/hr) = Dose per kg × Weight. Dose = 0.5 mg/kg/hr × 70 kg = 35 mg/hr. Step 2: Determine the volume to administer using the concentration. Volume (mL/hr) = Dose ÷ Concentration = 35 ÷ 2. Volume = 17.5 mL/hr.
C. This value represents the total milligrams (35 mg) required per hour. This is a common "distractor" error where the total dose is calculated, but the final step, converting milligrams to milliliters based on concentration, is omitted.
D. This result is mathematically unrelated to the provided variables. It could be the result of a calculation error such as dividing the weight by the dose or concentration incorrectly.

Correct Answer is A
Explanation
A. Document findings and report suspicions to the appropriate authorities is correct. When elder abuse is suspected, the nurse’s legal and ethical responsibility is to accurately document objective findings and report the suspicions to mandated authorities, such as adult protective services. Prompt reporting helps protect the client and initiates an official investigation.
B. Confronting the alleged abuser directly is not appropriate. This can escalate the situation, put the elder client at further risk, and may interfere with the investigation. Nurses should avoid direct confrontation with the suspected abuser.
C. Discussing the situation with the elder client’s family may be unsafe or inappropriate, especially if the family member is the suspected abuser. This step should not precede documentation and reporting to authorities.
D. Creating a safety plan with the client’s consent is important for long-term protection, but it is secondary to the immediate priority of documenting and reporting suspected abuse. Ensuring official intervention comes first to reduce imminent risk.
Correct Answer is A
Explanation
A. Referring the adolescent to resources aimed at reducing socioeconomic stressors is correct. social determinants of health recognizes that factors such as poverty, food insecurity, and unstable housing can exacerbate depression in adolescents. Connecting the adolescent and family to support programs (e.g., food assistance, housing resources, financial aid) helps alleviate stressors contributing to depressive symptoms and promotes overall mental health.
B. Advising the family to relocate may not be feasible due to financial constraints. While neighborhood conditions can influence mental health, suggesting relocation without considering resources is unrealistic and may increase stress, making it an inappropriate intervention.
C. Focusing solely on the adolescent’s mental health without addressing socioeconomic factors is incomplete. Effective depression management, especially in adolescents living in poverty, requires a holistic approach that considers environmental and social contributors to mental health.
D. Encouraging mental health treatment without considering financial challenges may result in limited access to care. Interventions must be tailored to the adolescent’s resources to ensure adherence and effectiveness.
