A staff nurse is observing a newly licensed nurse suction a client’s tracheostomy.

Which of the following actions by the newly licensed nurse requires intervention by the staff nurse?

The correct answer is b. Remove the device from the room.

Choice A rationale:

• Reporting the defect to the equipment maintenance staff is essential,but it's not the immediate priority.The primary concern is to eliminate the safety hazard posed by the frayed cord to prevent potential harm to the client and others.
• Delaying the removal of the device could lead to electrical shock,fire,or other serious consequences.
• Therefore,removing the device from the room takes precedence over reporting the defect.

Choice B rationale:

• Removing the device from the room is the most appropriate first action because it:
  • Eliminates the immediate safety hazard.
  • Prevents potential harm to the client and others.
  • Protects the device from further damage.
  • Ensures the safety of the environment.
  • Demonstrates the nurse's prioritization of patient safety.

Choice C rationale:

• Initiating a requisition for a replacement CPM device is necessary to ensure the client's continued treatment.
• However,it's not the first action because it doesn't address the immediate safety concern.
• The nurse should first remove the faulty device and then initiate the process for obtaining a replacement.

Choice D rationale:

• Ensuring the device inspection sticker is current is a vital part of equipment maintenance.
• However,it's not relevant to the immediate safety issue of the frayed cord.
• The presence of a current inspection sticker doesn't guarantee the device's safety or functionality at that moment.
• The nurse must prioritize removing the hazard and then follow up with appropriate documentation and reporting.

Answer:D. Troponin T test

Rationale:

A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.

B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.

C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.

D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.
