A patient with acute respiratory distress syndrome is receiving a paralyzing agent. With a Train-of-four (TOF) assessment, the patient’s thumb twitches 3 times. How would the nurse interpret this response?
The patient’s paralysing agent dose in adequate, but needs to be given more often
The patients paralyzing agent dose is too low and needs to be increased
The patient’s paralyzing agent dose in appropriate and does not need to be changed
The patients paralyzing agent dose is too high and needs to be reduced
The Correct Answer is A
A. The patient’s paralyzing agent dose is adequate, but needs to be given more often.
In a Train-of-four (TOF) assessment, four stimuli are delivered in rapid succession, and the response is observed. The number of twitches in the patient's thumb indicates the degree of neuromuscular blockade. In this case, if the patient's thumb twitches three times, it suggests that there is still some residual neuromuscular blockade, and the paralyzing agent dose is adequate. However, the frequency of administration may need to be increased to maintain the desired level of paralysis or neuromuscular blockade.
B. The patient’s paralyzing agent dose is too low and needs to be increased:
This would be indicated if there were fewer than three twitches in response to the TOF assessment.
C. The patient’s paralyzing agent dose is appropriate and does not need to be changed:
The response of three twitches suggests that there is still some neuromuscular blockade, so the dose or frequency may need adjustment.
D. The patient’s paralyzing agent dose is too high and needs to be reduced:
If there were no twitches or a complete absence of twitches, this might suggest an excessive dose. However, three twitches indicate some degree of neuromuscular blockade.

Correct Answer is B
Explanation
A. “Check your oxygen equipment once each week.”
Checking the oxygen equipment once a week is insufficient. The equipment should be regularly inspected for safety, including tubing, connections, and the condition of the oxygen concentrator or tank.
B. “Do not adjust the oxygen flow rate.”
The nurse should include in the teaching that the client should not adjust the oxygen flow rate without consulting their healthcare provider. Adjusting the oxygen flow rate without proper guidance can lead to inappropriate oxygen delivery, which may be harmful.
C. “Store unused oxygen tanks horizontally.”
Oxygen tanks should be stored in an upright position to prevent damage to the tank valve. Storing them horizontally can increase the risk of leaks or damage.
D. “Keep wool blankets on your bed.”
Wool blankets and other items that generate static electricity should be avoided near oxygen equipment, as they can increase the risk of fire. The client should be advised to use non-static bedding and clothing.
Correct Answer is A
Explanation
A. Cooperating:Cooperating involves working together to find a mutually beneficial solution. In this case, the charge nurse resolves the conflict by allowing both nurses to go to lunch together and taking care of their clients, ensuring that both nurses’ needs are met.
B. Avoiding:Avoiding means ignoring the conflict or withdrawing from the situation. The charge nurse is not ignoring the conflict; rather, they are actively facilitating a resolution by allowing both nurses to take lunch together.
C. Compromising:Compromising involves both parties giving up something to reach a mutually acceptable solution. While the charge nurse is helping to resolve the conflict by allowing the nurses to go to lunch, it does not imply that either nurse has made a concession in their argument, making this option less accurate.
D. Competing:
Competing involves pursuing one's own concerns at the expense of others. It is a win-lose approach to conflict resolution. The charge nurse is not demonstrating a competitive approach in this scenario, as both nurses are accommodated to go to lunch together without one person's needs being prioritized over the other.
