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

Answer and Explanation

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

Explanation

Choice A Reason;
"You should consume small, frequent meals each day." This statement is advisable for COPD management. Eating smaller, more frequent meals can help prevent bloating or feeling overly full, which might interfere with breathing due to increased pressure on the diaphragm.
Choice B Reason:
"You should decrease your caloric intake by 200 calories per day." While maintaining a healthy weight is important for COPD management, reducing caloric intake without specific guidance or assessment might not be suitable. It's crucial to consult with a healthcare provider or dietitian for individualized dietary recommendations.
Choice C Reason:
"You should increase your oxygen to 5 liters per minute if you have shortness of breath." Adjusting oxygen flow should be done based on a healthcare provider's prescribed guidelines. Self-adjustment of oxygen flow without medical advice can be risky and might not address the underlying cause of shortness of breath during a COPD exacerbation.
Choice D Reason:
"You should discontinue your prednisone when your symptoms improve." Prednisone or other corticosteroids are often prescribed during a COPD exacerbation to reduce inflammation in the airways. However, discontinuing corticosteroids abruptly without a healthcare provider's guidance can lead to a recurrence of symptoms or potential complications. It's important to follow the prescribed regimen and complete the course as directed.

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.
