A nurse is assessing a client who received a Mantoux skin test 72 hr ago for tuberculosis screening. Which of the following findings indicates a positive test result?
A blister-like area
A cool, blanched area
An elevated, hardened area
An area of ecchymosis
The Correct Answer is C
Rationale:
A. A blister-like area: Blistering is not the expected reaction used to interpret a Mantoux test. The result is based on the presence and size of induration, not the formation of blisters.
B. A cool, blanched area: Coolness and blanching are not indicators of a positive test. These findings may reflect poor circulation or local skin reaction unrelated to tuberculosis screening.
C. An elevated, hardened area: Induration (elevated, firm area) at the injection site, measured in millimeters, is the basis for determining a positive result. The size threshold for positivity depends on the client’s risk factors for tuberculosis.
D. An area of ecchymosis: Bruising at the site is a local skin reaction that can occur after any injection and is unrelated to the diagnostic criteria for a positive Mantoux test.

Correct Answer is D
Explanation
A. Weight gain 2.3 kg (5 lb): Mild weight gain can occur with oral contraceptive use and is generally not dangerous. This finding does not require immediate reporting.
B. Frequent nausea: Nausea is a common side effect, especially during the first few months of therapy. While bothersome, it is usually not an urgent concern unless severe or persistent.
C. Breast tenderness: Breast tenderness is a common, mild side effect of oral contraceptives and does not typically indicate a serious problem requiring immediate intervention.
D. Persistent headache: A new, persistent, or severe headache can indicate vascular complications, such as hypertension or increased risk of thromboembolism, which are serious adverse effects of oral contraceptives. This finding requires immediate reporting.
Correct Answer is C
Explanation
A. Personalize the conflict: Making a conflict personal can increase tension and defensiveness among staff. Effective negotiation requires addressing issues objectively rather than targeting individuals.
B. Identify solutions prior to negotiation: Preselecting solutions may limit collaborative problem-solving. Effective negotiation involves exploring options with all parties to reach mutually acceptable outcomes.
C. Attempt to understand both sides of the issue: Understanding each party’s perspective promotes open communication, trust, and collaboration. This approach helps identify common ground and develop solutions that are acceptable to all involved.
D. Focus on how the conflict occurred: Concentrating on past events can create blame and hinder forward-focused problem-solving. Effective negotiation emphasizes current needs and potential solutions rather than dwelling on the cause.
