The nurse is caring for a patient with a left radial arterial line and a pulmonary artery catheter inserted into the right subclavian vein. Which action by the nurse best ensures the safety of the patient being monitored with invasive hemodynamic monitoring lines?
Document all waveform values.
Limit the pressure tubing length.
Zero reference the system daily.
Ensure alarm limits are turned on
The Correct Answer is D
A. Documentation of waveform values is important but does not directly enhance patient safety during monitoring.
B. Limiting the pressure tubing length can help maintain accuracy, but it is not the primary safety measure.
C. Zero referencing is crucial for accurate readings, but it must be done in conjunction with ensuring alarms are active.
D. Ensuring that alarm limits are turned on and appropriately set is the best safety measure to immediately alert the nurse to any critical changes in the patient's status.

Correct Answer is B
Explanation
A. While lowering BP to 120/80 may be an ultimate goal, it is not the initial target in a hypertensive emergency.
B. Rapid reduction in blood pressure can cause hypoperfusion of vital organs such as the brain, heart, and kidneys, leading to ischemic injury. The aim is to reduce the BP gradually to prevent these complications.
C. IV antihypertensive medications generally have a rapid onset, not a slow one.
D. While gradual reduction is important, it is not done to allow rest but to protect organ perfusion.
