Final answer:
The nurse should suspect a transfusion reaction based on the client's anxiety, headache, back pain, pale skin, and changes in vital signs.
Step-by-step explanation:
Based on the assessment findings, the nurse should suspect a transfusion reaction based on the following:
- Anxiety: The client reports feeling anxious about the transfusion, which can be a sign of a reaction.
- Headache: The client requests pain medication for a headache, which can be a symptom of a transfusion reaction.
- Back pain: The client reports back and joint pain, which can also be a symptom of a transfusion reaction.
- Skin: The client's skin is pale, cool, and dry to the touch, which can indicate a reaction.
- Vital signs: Although the vital signs are within normal range, the increasing heart rate and changes in blood pressure can be signs of a reaction.
