Which of the following are two examples of intrathecal procedures?

Myelograms and epidural injections are indeed two examples of intrathecal procedures because they both involve the administration of medications or contrast agents directly into the spinal canal, specifically within the subarachnoid space where the cerebrospinal fluid (CSF) circulates.

In a myelogram, a contrast dye is injected to enhance imaging of the spinal cord and nerve roots, allowing for clearer visualization during radiological examinations. This process is critical for diagnosing conditions affecting the spinal cord, such as herniated discs or spinal stenosis.

Epidural injections involve the injection of medication, often corticosteroids or anesthetics, into the epidural space to relieve pain, notably in cases of radiculopathy or chronic back pain. While it is slightly different from the intrathecal space, it is related and focuses on therapeutic interventions involving the spine.

The other choices involve routes of administration that do not provide access to the central nervous system. Blood transfusions and IV therapy are systemic approaches that deliver fluids or medications directly into the bloodstream, while subcutaneous injections and allergy tests pertain to the delivery of medications or allergens into the subcutaneous tissue. Intramuscular (IM) injections and venipuncture also do not relate to the direct administration
