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

Answer and Explanation

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 C

Explanation

A. The AP’s rapport with clients:
While a positive rapport with clients is valuable, it is not a direct factor in determining whether an AP is suitable for a specific task based on the five rights of delegation.

B. The AP’s ability to complete the task without assistance:
The ability to complete a task without assistance is relevant but does not guarantee that the AP has the necessary knowledge and skill for the task. The focus should be on competence rather than independence.

C. The AP has the knowledge and skill to perform the task
When considering the five rights of delegation, one of the crucial factors is ensuring that the assistive personnel (AP) has the knowledge and skill necessary to perform the delegated task safely and effectively. Delegated tasks should align with the AP's competence and training to maintain the safety and well-being of the client.

D. The AP’s ability to prioritize:
Prioritization skills are important for healthcare providers, but the focus of delegation, as per the five rights, is on the AP's competence to perform the specific task.

A. Pneumothorax B. Atelectasis C. Hemothorax D. Flail chest

Correct Answer is D

Explanation

A. Pneumothorax: A pneumothorax occurs when air accumulates in the pleural space, causing the lung to collapse. It often presents with unilateral chest pain, dyspnea, and diminished or absent breath sounds on the affected side.

B. Atelectasis: Atelectasis refers to the collapse of alveoli in the lungs, often caused by obstruction, compression, or lack of surfactant. Symptoms include hypoxemia, diminished breath sounds, and shortness of breath.

C. Hemothorax: A hemothorax occurs when blood accumulates in the pleural space. It typically presents with chest pain, dyspnea, and diminished or absent breath sounds on the affected side.

D. Flail Chest: Flail chest results from multiple rib fractures that create a free-floating segment of the chest wall. This condition causes paradoxical chest movement, where the chest wall segment moves inward during inspiration and outward during expiration.
