A nurse is reviewing the ABG values of a client who has pneumonia. Which of the following findings indicates the client is developing respiratory acidosis?

Choice C Hemoglobin 8.6 g/dL indicates the nurse should notify the provider because it is below the normal range of 12 to 18 g/dL and suggests blood loss or anemia, which can impair oxygen delivery to tissues and affect wound healing.

Choice a is not correct because blood glucose 98 mg/dL does not indicate the nurse should notify the provider because it is within the normal range of 70 to 110 mg/dL and does not indicate hyperglycemia or hypoglycemia, which can affect recovery.

Choice b is not correct because BUN 18 mg/dL does not indicate the nurse should notify the provider because it is within the normal range of 10 to 20 mg/dL and does not indicate renal impairment or dehydration, which can affect fluid and electrolyte balance.

Choice d is not correct because potassium 3.5 mEq/L does not indicate the nurse should notify the provider because it is within the normal range of 3.5 to 5 mEq/L and does not indicate hypokalemia or hyperkalemia, which can affect cardiac function and muscle contraction.

The sequence the nurse should use to administer the medication using the Z-track technique is:

- Step 1: Put on gloves and cleanse the site with an antiseptic swab.

- Step 2: Use the nondominant hand to pull the skin and subcutaneous tissue 2.5 cm (1 in) laterally.

- Step 3: Insert the needle into the muscle.

- Step 4: Aspirate by pulling back on the plunger and inject the medication.

- Step 5: Remove the needle and release the tissue.
