Which type of tablet is specifically designed to bypass dissolution in the stomach to protect the gastric lining?

A. At the measurement line: While graduated cylinders have marked measurement lines, the correct technique requires reading the meniscus rather than aligning the eye with a line on the cylinder. Measurement lines alone do not ensure accuracy.

B. At the base of the meniscus: Liquid in a cylinder forms a concave curve, and the correct volume is read at the lowest point of this meniscus at eye level. This method ensures precise measurement and prevents dosing errors.

C. At the bevel: The bevel refers to the slanted edge of a syringe needle, not a graduated cylinder. Reading at the bevel is irrelevant and would produce inaccurate volume readings.

D. At the top of the cylinder: Reading the top of the liquid meniscus overestimates the volume and can result in administering an incorrect dose. Accuracy requires aligning the eye with the meniscus base.

A. Pull the skin laterally with the non-injecting hand and maintain this position until the needle is withdrawn slowly, and release the skin slowly: The Z-track technique displaces subcutaneous tissue to create a zigzag path, preventing medication from leaking into subcutaneous tissue. Maintaining lateral tension during injection and slow withdrawal ensures proper deposition and minimizes tissue irritation.

B. Pull the skin taut with the forefinger and thumb of the non-dominant hand before needle insertion: Pulling the skin taut is not part of the Z-track method and does not create the necessary tissue displacement. This technique is more appropriate for standard intramuscular injections without irritant medications.

C. Release the displaced skin quickly before removing the needle to minimize skin trauma: Releasing the skin before needle withdrawal would allow medication to track back into subcutaneous tissue, increasing irritation and tissue staining. Maintaining tension until withdrawal is critical.

D. Massage the injection site vigorously after needle withdrawal to disperse the medication and reduce pain: Massaging an irritant IM injection site can worsen tissue damage, cause staining, and increase discomfort. The Z-track technique is designed to prevent the need for post-injection massage.
