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:

When leaving a client's isolation room, the nurse should remove gloves (Choice A) first. Gloves are considered contaminated and can harbor microorganisms. Removing them first helps prevent the spread of potential pathogens to other surfaces or items while removing other personal protective equipment (PPE).

Choice B rationale:

Goggles (Choice B) protect the eyes from splashes and airborne particles. However, they should be removed after gloves. Gloves have a higher potential for contamination due to direct contact with the client and the environment.

Choice C rationale:

Removing the gown (Choice C) should follow the removal of gloves and goggles. The gown provides a barrier against potential contaminants and should be taken off to prevent self-contamination while disrobing from other PPE.

Choice D rationale:

The mask (Choice D) should be removed last. It provides respiratory protection and prevents the nurse from inhaling airborne particles. Keeping the mask on while removing other PPE items helps maintain a barrier against potential exposure to respiratory pathogens.

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.
