A nurse is assessing a client who has started taking theophylline. Which of the following client findings should indicate to the nurse that the medication is effective?

A. Vomiting 30 mL of fluid. This finding is not the priority because while vomiting can be a side effect of morphine, it is not immediately life-threatening.
B. Blood pressure 90/60 mm Hg. This finding is concerning but not the priority. Morphine can cause hypotension, but the primary concern with morphine administration is respiratory depression.
C. Respirations deep at a rate of 10/min. This finding is the priority because morphine can cause respiratory depression, which can be life-threatening. Monitoring and addressing respiratory status is critical when administering opioids.
D. Urinary output of 20 mL within 1 hr. This finding is concerning but not the priority. Low urinary output can indicate dehydration or renal issues, but respiratory depression is the most immediate concern with morphine administration.

A. Massage the injection site after administering the medication. This action is incorrect because massaging the injection site after administering enoxaparin can cause bruising and should be avoided.
B. Administer the medication into the anterolateral or posterolateral abdominal area. This action is correct. Enoxaparin should be administered subcutaneously into the anterolateral or posterolateral abdominal area to ensure proper absorption and minimize complications.
C. Hold the skin taut at the injection site while administering the medication. This action is incorrect. The correct technique involves pinching a fold of skin to create a subcutaneous pocket for the injection, rather than holding the skin taut.
D. Expel the air bubble from the syringe prior to administering the medication. This action is incorrect. The air bubble in prefilled enoxaparin syringes should not be expelled before administration, as it helps to ensure the full dose is delivered and reduces the risk of bruising.
