A nurse is reviewing the EKG strip of a client who has End Stage Renal Disease (ESRD) and has missed hemodialysis. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hyperkalemia?
Prolonged P-R interval
Peaked T waves
Elevated ST segment
Inverted P wave
The Correct Answer is B
A. Prolonged P-R interval: A prolonged P-R interval may indicate an atrioventricular (AV) block or conduction delay, but it is not specifically associated with hyperkalemia.
B. Peaked T waves: Peaked T waves are a classic EKG finding in hyperkalemia. Hyperkalemia can affect cardiac repolarization, leading to tall, peaked T waves on the EKG.
C. Elevated ST segment: An elevated ST segment may indicate myocardial injury or ischemia but is not typically associated with hyperkalemia.
D. Inverted P wave: An inverted P wave may indicate atrial enlargement or conduction abnormalities but is not specifically associated with hyperkalemia.

Correct Answer is ["A","B","D","E"]
Explanation
A. Elevating the head of the bed 30 to 45 degrees helps prevent aspiration, which is a risk factor for ventilator-associated pneumonia.
B. Performing hand hygiene before touching the ventilator tubing is crucial to prevent the introduction of pathogens into the ventilator system.
C. Refraining from suctioning the client is incorrect; suctioning should be performed as needed to keep the airway clear.
D. Providing mouth care every 2-4 hours can reduce the risk of pathogens entering the lower respiratory tract.
E. Performing hand hygiene before touching the client reduces the risk of transmitting infectious agents to the client.
Correct Answer is B
Explanation
A. Document how many inches the tube has been inserted: While documentation of the tube insertion depth is important, it is not the highest priority immediately after intubation. Ensuring proper placement and ventilation take precedence.
B. Auscultate both lungs for the presence of breath sounds: This is the priority action to confirm that the endotracheal tube is correctly placed in the trachea and that both lungs are being ventilated adequately. Absence of breath sounds on one side could indicate mainstem intubation or displacement of the tube.
C. Secure the endotracheal tube to prevent dislodgement: Securing the tube is important, but it should be done after confirming proper placement and ventilation.
D. Obtain a chest x-ray to ensure correct tube placement: While a chest x-ray is often performed after intubation to confirm tube placement, it is not the immediate priority. Auscultation provides more immediate feedback on the effectiveness of ventilation.
