Final answer:
The statement that keeping the alarms set properly is an important nursing implication for an arterial line (A-line) is true. These alarms are crucial for patient safety by alerting healthcare staff to significant changes or problems with the A-line.
Step-by-step explanation:
An arterial line (A-line) is a catheter placed in an artery, most frequently used in intensive care medicine to monitor blood pressure in real-time and to obtain samples for arterial blood gas analysis. An important nursing implication of an A-line would be to keep the alarms set properly, which is true. This is critical because the alarms are designed to alert healthcare professionals to potential problems such as disconnections, occlusions, or significant changes in the patient's blood pressure that could indicate a serious alteration in physiological status. Proper management of these alarms helps to ensure patient safety and the integrity of the arterial line.
