An occupational health nurse is interpreting the results of a tuberculin skin test for a group of clients who received the test 48 hr ago. Which of the following clients should the nurse identify as having a positive test result?
A client whose injection site is scabbed
A client whose injection site is firm and measures 3 mm (0.1 in)
A client whose injection site has an elevated area measuring 15 mm (0.6 in)
A client whose injection site is ecchymotic
The Correct Answer is C
Choice A Reason:
A client whose injection site is scabbed is incorrect. Scabbing at the injection site does not provide information about the presence or absence of induration. It doesn't contribute to interpreting the test result directly.
Choice B Reason:
A client whose injection site is firm and measures 3 mm (0.1 in) is incorrect. A measurement of 3 mm of induration is generally considered a negative result for most individuals, including those without any risk factors for tuberculosis (TB).
Choice C Reason:
A client whose injection site has an elevated area measuring 15 mm (0.6 is correct. An area of induration measuring 15 mm or more is considered positive in individuals with no known risk factors for TB.
Choice D Reason:
A client whose injection site is ecchymotic is incorrect. Ecchymosis (bruising) at the injection site is not relevant to the interpretation of the tuberculin skin test. It does not contribute to determining a positive or negative result.

Correct Answer is ["A","C","D"]
Explanation
Choice A Reason:
Maintaining skin integrity over the blisters is correct. Blisters form as a protective mechanism for the skin underneath. Popping or breaking blisters increases the risk of infection as it exposes the raw skin to bacteria and other contaminants.
Choice B Reason:
Applying ice to the larger blisters is incorrect.
Reason: Applying ice directly to a burn, especially to blisters, can further damage the skin and exacerbate the injury. Ice can cause additional skin damage and can potentially increase pain and delay healing.
Choice C Reason:
Administering ibuprofen for pain is correct. Ibuprofen is an effective over-the-counter pain reliever that can help manage the discomfort caused by a minor burn. It also has anti-inflammatory properties that can reduce swelling associated with burns.
Choice D Reason:
Running cool water over the affected area is correct. Running cool (not cold) water over the burn helps to cool down the burned area, soothes the pain, and helps prevent further damage to the skin. It's recommended to run water over the burn for around 10-15 minutes to effectively cool the area.
Choice E Reason:
Allowing the affected area to remain open to air is incorrect. Keeping a minor burn uncovered can increase the risk of infection as it exposes the burn to external contaminants. Covering the burn with a sterile, non-stick dressing can protect it from further damage and reduce the risk of infection.
Correct Answer is ["1000"]
Explanation
To lose 0.9 kg (2 lb) of body fat per week, the client needs to create a weekly caloric deficit of 7000 calories (3500 x 2).
This means that he needs to reduce his daily caloric intake by 1000 calories (7000 / 7).
The nurse should instruct the client to calculate his current daily caloric intake and then subtract 1000 calories from that amount. The nurse should also advise the client to eat a balanced diet and exercise regularly to achieve his weight loss goal.
