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
Explanation
Choice A Reason:
Assisting the client to the restroom 30 minutes after meals is correct recommendation. This intervention aligns with the natural response of the gastrocolic reflex, which often leads to increased colonic motility after eating. Timing the restroom visit to this period can take advantage of the body's natural tendency to have a bowel movement after meals, potentially aiding in achieving bowel continence.
Choice B Reason:
Limiting the client's physical activity until bowel continence is achieved is not appropriate. Physical activity can actually stimulate bowel function and regularity. Moderate physical activity, as appropriate for the client's condition, can promote regular bowel movements. Restricting physical activity might hinder the overall success of bowel training.
Choice C Reason:
Limiting the client's fluid intake to 1500 mL/dayis not appropriate. Adequate hydration is crucial for bowel health and regularity. Limiting fluid intake could lead to dehydration and constipation, which can exacerbate fecal incontinence. It's important to encourage adequate hydration unless there are specific medical reasons to restrict fluids.
Choice D Reason:
Instructing the client to limit their intake of high-fiber foods is incorrect. High-fiber foods are beneficial for bowel regularity and can help manage fecal incontinence by promoting healthy bowel movements. Limiting high-fiber foods could potentially lead to constipation or exacerbate the issue of fecal incontinence.
Correct Answer is B
Explanation
Choice A Reason
Using a hair dryer to blow hot air into the cast is not recommended. It can cause burns, soften the cast material, or create hot spots, potentially leading to skin damage or discomfort for the client.
Choice B Reason:
Perform neurovascular checks of the affected extremity every 2 hours is correct. Performing neurovascular checks regularly is crucial to assess the circulation, sensation, and movement of the affected extremity. This monitoring helps identify any signs of compromised blood flow or nerve function, which could indicate complications such as compartment syndrome.
Choice C Reason:
Positioning the fractured arm below the level of the client's heart is not advisable. Elevating the injured limb above heart level can help reduce swelling and promote blood flow, aiding in the healing process and preventing complications like swelling-related discomfort or decreased circulation.
Choice D Reason:
Immobilizing the client's fingers using a hand splint might not be necessary with a short arm cast. Typically, a short arm cast provides immobilization of the wrist and forearm while allowing some movement and function of the fingers unless specifically directed by the healthcare provider for individual circumstances.
