A nurse manager is providing teaching to a newly licensed nurse about Mantoux testing. Which of the following clients should the nurse manager include as an example of a client who might manifest a false-positive reading?
A client who has undergone radiation therapy within the last 3 years
A client who has received the bacille Calmette-Guerin vaccine within the last 10 years
A client who has acquired immune deficiency syndrome
A client who has lived in a country where tuberculosis is endemic
The Correct Answer is B
A. A client who has undergone radiation therapy within the last 3 years: Radiation therapy may suppress the immune response, potentially leading to a false-negative rather than a false-positive Mantoux test due to reduced ability to mount a reaction.
B. A client who has received the bacille Calmette-Guerin vaccine within the last 10 years: The BCG vaccine can cause a false-positive Mantoux result because the vaccine uses a strain of Mycobacterium bovis, which can trigger a reaction similar to TB exposure in skin testing.
C. A client who has acquired immune deficiency syndrome: Clients with AIDS are immunocompromised, which increases the likelihood of a false-negative Mantoux result, as their immune systems may not respond sufficiently to the test.
D. A client who has lived in a country where tuberculosis is endemic: This client is at higher risk for true TB exposure, and a positive result is more likely to reflect actual infection rather than a false-positive reaction.

Correct Answer is C
Explanation
A. The client has gained 4.5 kg (10 lb) over 8 weeks: Weight gain may indicate changes in diet, activity, or medication, but it does not directly suggest a need for physical therapy. A nutritionist or primary care provider might be more appropriate for follow-up.
B. The caregiver reports that recently the client is incontinent of urine during the day:
Urinary incontinence in clients with Alzheimer's is typically addressed by primary care or urology. It may be related to cognitive decline rather than physical impairment, so physical therapy is not the priority referral.
C. The client is unable to climb the stairs to their bedroom: This mobility limitation increases the risk for falls and functional decline. A physical therapist can assess strength, balance, and coordination, and develop a mobility plan or recommend assistive devices or home modifications.
D. The caregiver reports the client needs assistance with activities of daily living such as bathing: This indicates a need for occupational therapy to enhance independence in daily tasks. While physical therapy may support mobility, ADL support is better addressed by an occupational therapist.
Correct Answer is ["A","D","E"]
Explanation
A. Teaching a class about the risks of cigarette smoking: This is a primary prevention activity focused on educating children to prevent the initiation of smoking and related health problems before they occur.
B. Recommending a seating arrangement for a child in a body cast: This is a tertiary prevention activity that involves managing existing health conditions and preventing complications, not primary prevention.
C. Creating a plan of care for children who have a diagnosis of diabetes mellitus: This is tertiary prevention since it deals with managing an existing chronic illness to reduce complications.
D. Organizing a program to promote skateboard safety: This is primary prevention, aiming to prevent injuries associated with skateboarding by teaching safe practices before accidents happen. It targets a behavior to prevent harm.
E. Lobbying for funding for health promotion efforts: This supports primary prevention. By securing resources for health promotion, the nurse is contributing to initiatives that aim to prevent illness and promote well-being across the school community before health problems arise.
