A nurse is preparing to administer haloperidol 5 mg by IV bolus over 15 min. Available is haloperidol 5 mg in 50 mL dextrose 5% in water (D5W). The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["200"]
Step 1: Identify total volume and infusion time
Total volume = 50 mL
Infusion time = 15 minutes
Step 2: Use the formula for IV flow rate
Flow rate (mL/hr) = (Total volume ÷ Time in minutes) × 60
Flow rate = (50 ÷ 15) × 60
Flow rate ≈ 3.333 × 60 ≈ 200 mL/hr
Final Answer: 200 mL/hr

Correct Answer is D
Explanation
A. Family studies indicate that mental illness often has a genetic component, so stating there is no genetic association is inaccurate.
B. While regular healthcare appointments can help with early identification and management, mental illness cannot be completely prevented solely through routine care; genetics and environmental stressors also play significant roles.
C. Twin studies show that both genetics and environmental factors, including stress, contribute to mental illness, so claiming stress is unrelated is incorrect.
D. Adoption studies demonstrate that individuals are more likely to develop certain mental illnesses if their biological parents had the disorder, even when raised by adoptive parents. This supports the concept of a genetic correlation in mental illness while also highlighting the interaction with environmental factors.
Correct Answer is C
Explanation
A. Having a mother who was a teenager at the time of birth does not inherently indicate a protective factor; it may present additional stressors.
B. Worrying about a sibling’s health and frequent hospitalizations indicates stress and potential risk factors, rather than protective factors.
C. Having a supportive and attentive teacher demonstrates a positive childhood experience that can serve as a protective factor, providing emotional support, stability, and a trusted adult relationship that buffers against the effects of anxiety and stress.
D. Frequent relocations due to military life can contribute to instability and disrupted social support, which are not considered protective factors.
