A client with a spinal cord injury at T6 suddenly reports a pounding headache and blurred vision. What action should the nurse take first?
- A. Administer pain medication as ordered.
- B. Check the client's blood pressure.
- C. Place the client in a supine position.
- D. Increase the client's fluid intake.
Correct Answer: B
Rationale: The correct action is to check the client's blood pressure first. A sudden onset of pounding headache and blurred vision in a client with a spinal cord injury at T6 can indicate autonomic dysreflexia. Checking the blood pressure is crucial as autonomic dysreflexia can lead to severe hypertension, which can result in life-threatening complications such as stroke or seizure. Immediate assessment and intervention are necessary to prevent further harm. Administering pain medication without addressing the underlying cause can exacerbate hypertension. Placing the client in a supine position can worsen symptoms, and increasing fluid intake does not address the immediate issue at hand. Therefore, checking the blood pressure is the priority to identify and manage autonomic dysreflexia effectively.

A client with a long history of smoking is being assessed by a nurse. Which finding is a common complication of chronic obstructive pulmonary disease (COPD)?
- A. Decreased anteroposterior chest diameter
- B. Increased breath sounds
- C. Prolonged expiratory phase
- D. Increased chest expansion
Correct Answer: C
Rationale: Step-by-step rationale:
1. COPD is characterized by airway obstruction, leading to difficulty exhaling.
2. Prolonged expiratory phase is a common finding due to air trapping.
3. This leads to hyperinflation and increased residual volume.
4. Decreased anteroposterior chest diameter is not typical in COPD.
5. Increased breath sounds and chest expansion are not common in COPD.
In summary, choice C is correct because it directly relates to the pathophysiology of COPD, while the other choices are not consistent with the condition.
