A nurse is caring for a client who requires contact precautions.
Which action should the nurse take with this client?

The correct answer is choice C: Move any clients to safety.

Choice C rationale: The nurse's priority is always client safety. In the event of an electrical issue that poses a potential risk, such as smoke or fire, the nurse should first ensure that any clients in the area are moved to a safe location. This aligns with the widely-used RACE acronym for fire response (Rescue, Alarm, Confine, Extinguish), which highlights the importance of removing individuals from danger before attending to other aspects of fire safety.

Choice A rationale: Using a fire extinguisher is an appropriate action to take when dealing with a small, manageable fire. However, in this scenario, ensuring client safety takes precedence over attempting to extinguish the source of the smoke. This is also in line with the RACE mnemonic, which emphasizes the importance of prioritizing evacuation.

Choice B rationale: Activating the fire alarm is an important step to alert others in the building about a potential fire and the need for evacuation. However, the priority remains client safety, so moving clients to a safe location should be the nurse's initial response, following the RACE acronym.

In summary, the nurse's priority action when encountering an electrical hazard is to move clients to safety. After ensuring client safety, the nurse can then activate the fire alarm and, if trained to do so, use a fire extinguisher on the outlet if necessary. This approach aligns with the RACE mnemonic, which serves as a guideline for fire response.

Choice A rationale:

Diastolic pressure represents the pressure in the arteries when the heart is at rest between contractions. It specifically measures the force of blood against the arterial walls when both the atria and ventricles are relaxed, allowing the heart to fill with blood. Diastolic pressure is the bottom number in a blood pressure reading (e.g., 120/80 mmHg), indicating the pressure in the arteries during the heart's resting phase. Elevated diastolic pressure is an important indicator of increased risk for cardiovascular diseases, such as hypertension.

Choice B rationale:

This statement describes systolic blood pressure, which measures the pressure in the arteries when the heart's ventricles contract and pump blood into the circulation. Systolic pressure is the top number in a blood pressure reading (e.g., 120/80 mmHg) and represents the highest pressure reached in the arteries during a cardiac cycle.

Choice C rationale:

This description is not accurate for either diastolic or systolic pressure. Both atria and ventricles do not contract simultaneously; they follow a specific sequence to ensure effective pumping of blood through the heart.

Choice D rationale:

This statement is incorrect as it does not align with the definitions of diastolic or systolic blood pressure. Diastolic pressure specifically measures the pressure in the arteries during the heart's resting phase, not when the ventricles relax. .
