Correct Answer is B
Explanation
Obtain a straight catheter kit to empty her bladder.
Reviewing the fetal heart rate pattern (Choice A) is important during labor, but in this scenario, the client's request to go to the bathroom and the lack of cervical changes are indicative of a potential bladder distention. Addressing the bladder concern should take precedence at this point.
Choice C rationale:
Checking the perineum for changes in "show”. or discharge (Choice C) is essential during labor to monitor progress, but it is not the priority in this situation. The client's request to empty her bladder should be addressed first.
Choice D rationale:
Assisting the client up to the bathroom (Choice D) without addressing the potential bladder distention may lead to complications. It is crucial to ensure the client's bladder is emptied properly, as a distended bladder can hinder progress and increase discomfort during labor.
Correct Answer is B
Explanation
The PN should not prioritize bringing a glucometer to the room in this situation. The client's unresponsiveness indicates a potential medical emergency that requires immediate action, and checking blood glucose levels is not the primary concern at this moment.
Choice C rationale:
Feeling for a carotid pulse is an essential step in assessing the client's circulation. However, it is not the first priority when the client is unresponsive. The PN should focus on obtaining emergency help first to ensure timely intervention.
Choice D rationale:
Checking the blood pressure can provide valuable information about the client's condition, but it is not the most critical step when dealing with an unresponsive client. Promptly seeking emergency assistance is more important to address the immediate concern.
