Nursing intervention during the lumbar puncture procedure includes:
Correct Answer: C
Rationale: During a lumbar puncture procedure, it is important to position the patient correctly to facilitate the procedure and minimize the risk of complications. Placing the patient on their side with their knees drawn up to their chest helps open up the spaces in the lower spine, making it easier for the healthcare provider to access the appropriate area for the procedure. This position also helps to minimize the risk of post-procedure complications such as spinal headaches. Monitoring the patient's vital signs is important but does not specifically relate to the nursing intervention during the lumbar puncture procedure. Labeling laboratory specimens in numerical order is also a routine task but not directly related to the procedure itself. Thus, the correct intervention during the lumbar puncture procedure is positioning the patient on their side with knees drawn up to the chest.
