A nurse is preparing to administer labetalol 40 mg IV to a client. Available is labetalol 5 mg/mL. How many mL should the nurse administer? (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 ["8"]
Calculation:
Desired dose = 40 mg.
Available concentration = 5 mg/mL.
- Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 40 mg / 5 mg/mL
= 8 mL.

Correct Answer is C
Explanation
Rationale:
A. Providing the client with information about transportation services: This helps address access barriers but focuses on support services rather than directly organizing or integrating healthcare delivery, which is central to coordination of care.
B. Informing the client about providers who accept their health insurance: While helpful, this action centers on financial guidance. It supports access but does not actively bridge or organize care among multiple services or settings.
C. Arranging an appointment for the client with a mobile health clinic: Coordinating an appointment directly connects the client with needed services, especially in underserved rural areas. This reflects active care coordination by ensuring timely access to care and reducing system fragmentation.
D. Encouraging the client to become a self-advocate: Promoting self-advocacy empowers the client in their health journey but does not represent coordination of care. Coordination involves organizing and facilitating access across providers and settings.
Correct Answer is C
Explanation
Rationale:
A. A small area rug is placed at the front door: Area rugs increase the risk of falls, especially in older adults or clients with mobility issues. Rugs should be removed or secured with non-slip backing to prevent tripping hazards at entrances and high-traffic areas.
B. The water heater is set at 54° C (129.2° F): This temperature is too high and poses a significant risk for burns or scalding. The recommended maximum water heater setting for safety is 49° C (120° F), especially in homes with children or older adults.
C. The batteries in the smoke alarms are changed annually: Changing smoke alarm batteries once a year aligns with fire safety recommendations. Functioning smoke alarms are a critical part of home safety and fire prevention.
D. A single light fixture hangs along the sidewalk to the house: One light may not provide adequate visibility, especially in poor weather or at night. Multiple, evenly spaced light sources are more effective for preventing trips or falls along walkways.
