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 B
Explanation
Choice A Reason:
"I can take my partner outside of the room as long as they wear a mask."MRSA contact precautions typically involve limiting the spread of the bacteria. Taking the partner outside the room while wearing a mask might not be sufficient for infection control, as MRSA can spread through direct contact with surfaces. This statement might not indicate a full understanding of MRSA precautions.
Choice B Reason:
"I will wash my hands as soon as I leave the room. “Hand hygiene is a crucial component of infection control for MRSA. Washing hands with soap and water or using alcohol-based hand sanitizer after leaving the room helps prevent the spread of MRSA to oneself or others.
Choice C Reason:
"I will wear a gown when I help my partner take a bath." Wearing a gown during tasks that might involve contact with the patient's bodily fluids or surfaces that might be contaminated is recommended for MRSA precautions. This statement aligns with infection control practices.
Choice D Reason:
"I can reuse unsoiled gloves when I re-enter the room. “Reusing gloves, even if they appear unsoiled, is generally not recommended as it can contribute to the spread of MRSA. Gloves should be disposed of after each use and hands washed thoroughly.
Correct Answer is C
Explanation
Choice A Reason:
"I'll make sure I stay away from microwave ovens." This statement is incorrect . While there were concerns about interference in the past, modern pacemakers are generally not affected by household appliances like microwave ovens.
Choice B Reason:
"I should have an MRI, rather than a CAT scan, if necessary." This statement is incorrect. Both MRI and CAT scans have considerations when a person has a pacemaker. An MRI might be contraindicated due to the magnetic field, while a CAT scan might be a safer imaging choice.
Choice C Reason:
"I'll hold my cell phone against the ear on the opposite side of my body." This statement reflects an understanding of the precaution to avoid holding a cell phone directly over the implanted pacemaker. Keeping the phone on the opposite side helps minimize the potential interference with the pacemaker's function.
Choice D Reason:
"I shouldn't travel by plane because of airport security." This statement is incorrect. Airport security systems generally don't affect pacemakers, so traveling by plane is usually safe. However, informing security personnel about the presence of a pacemaker is a good practice.
