Which nursing assessment indicates a positive reading of a tuberculin (TB) skin test?
1 day after injection with a 10-mm area of redness and swelling
2 days after injection with a 5-mm area of redness and swelling
4 days after injection with a 3-mm area of redness and swelling
5 days after injection with a 2-mm area of redness and swelling
The Correct Answer is A
A. 1 day after injection with a 10-mm area of redness and swelling:
This may suggest a positive reading, but induration size is the primary criterion for interpretation, not just redness and swelling.
B. 2 days after injection with a 5-mm area of redness and swelling:
Similar to option A, a 5-mm area of redness and swelling alone does not definitively indicate a positive TB skin test. Again, without information on the size of the induration, we cannot determine if this reading is positive.
C. 4 days after injection with a 3-mm area of redness and swelling:
Once more, a 3-mm area of redness and swelling alone does not definitively indicate a positive TB skin test. As with the previous options, the size of the induration is the critical factor for interpretation.
D. 5 days after injection with a 2-mm area of redness and swelling:
As with the other options, a 2-mm area of redness and swelling alone does not definitively indicate a positive TB skin test. The presence and size of induration are essential for accurate interpretation.

Correct Answer is D
Explanation
A. Position the client on the nonoperative side.
Positioning the client on the nonoperative side after a pneumonectomy may not be the best choice. The positioning of the client post-pneumonectomy should be based on factors such as the individual's comfort, respiratory status, and any specific instructions from the healthcare provider. Placing the client on the nonoperative side may inadvertently put pressure on the surgical site, leading to discomfort or potential complications.
B. Monitor respiratory status every 8 hr.
Monitoring respiratory status every 8 hours is not sufficient for a client post-pneumonectomy. After such a major surgical procedure, respiratory status should be closely monitored and assessed more frequently, especially in the immediate postoperative period. This frequency allows for the early detection of any signs of respiratory distress, such as decreased oxygen saturation, dyspnea, or abnormal breath sounds, as well as complications like pneumothorax or atelectasis.
C. Elevate the head of the bed to a 15° angle.
Elevating the head of the bed to a 15° angle is a general recommendation for clients postoperative to promote respiratory function and reduce the risk of aspiration. However, after a pneumonectomy, the positioning of the client may vary based on their individual condition and surgical approach. It's important to follow the healthcare provider's specific instructions regarding positioning for optimal recovery. The angle of elevation may need to be adjusted based on the client's comfort and respiratory status.
D. Encourage the client to splint the incision when coughing.
After a pneumonectomy, it's crucial to encourage the client to splint the incision when coughing. Splinting the incision with a pillow or hands helps to reduce pain and prevent strain on the surgical site, promoting healing and minimizing the risk of complications such as wound dehiscence (opening of the surgical incision).
