A nurse is reviewing the ABG results for a client. The client's results are pH 7.47, PaCO2 30 mm Hg, HCO3 25 mEq/L, and SaO2 90%. The nurse should identify that the client is experiencing which of the following acid-base imbalances?

Choice A rationale:

Selecting an injection site on the abdomen 5 cm (2 in) from the umbilicus might be an appropriate instruction for some subcutaneous injections, but the specific injection site can vary based on the medication and client's needs. This choice is not a universal instruction for all subcutaneous injections.

Choice B rationale:

Expelling the air bubble from a prefilled syringe before injecting the medication is essential to ensure accurate dosing. Air bubbles can displace medication and lead to underdosing. This step is crucial for safe and effective administration.

Choice C rationale:

Aspirating prior to injecting medication is a technique used for intramuscular injections to ensure the needle is not in a blood vessel. However, for subcutaneous injections, aspirating is not necessary or recommended, as it can cause tissue damage and discomfort.

Choice D rationale:

Inserting the needle at a 15° angle is not a standard practice for subcutaneous injections. Subcutaneous injections are typically administered at a 45° or 90° angle, depending on the needle length and client's body composition. A 15° angle would not ensure proper medication delivery.

Choice A rationale:

Instructing the client to remain supine for 10 minutes after inserting a vaginal suppository helps ensure proper absorption of the medication. This position allows the suppository to stay in contact with the vaginal mucosa, promoting optimal drug absorption. This is an essential nursing action to maximize the therapeutic effect of the medication.

Choice B rationale:

Applying sterile gloves after cleansing the perineal area is not necessary when administering a vaginal suppository. While maintaining cleanliness is important, the use of sterile gloves is not typically required for this procedure. Clean, non-sterile gloves are sufficient to maintain aseptic technique during the administration.

Choice C rationale:

Inserting the suppository 3 to 4 cm (1 to 1.5 in) into the vagina is an appropriate depth for vaginal suppository insertion. The nurse should follow this guideline to ensure that the medication reaches the appropriate location within the vaginal canal, optimizing absorption and effectiveness.

Choice D rationale:

Placing the client in the lateral semi-prone recumbent position is not a standard position for administering a vaginal suppository. The suppository is typically administered with the client lying on their back (supine) to facilitate insertion and medication absorption. Placing the client in the position described would not provide the optimal angle for insertion.
