A nurse is assessing a client who received a Mantoux skin test 72 hours ago for tuberculosis screening. Which of the following findings indicates a positive test result?
A blister-like area.
An area of ecchymosis.
A cool, blanched area.
An elevated, hardened area.
The Correct Answer is D
Choice A reason: A blister-like area is not indicative of a positive Mantoux test, which shows induration; blisters suggest irritation. Assuming blisters are positive risks misdiagnosis, potentially missing tuberculosis exposure, critical to avoid in ensuring accurate screening and follow-up in clients tested for TB.
Choice B reason: Ecchymosis (bruising) is not a positive Mantoux result; induration indicates exposure. Assuming ecchymosis is positive risks incorrect interpretation, potentially overlooking tuberculosis risk, critical to prevent in ensuring proper screening, diagnosis, and follow-up for clients undergoing TB skin testing.
Choice C reason: A cool, blanched area suggests no reaction, not a positive Mantoux test, which requires induration. Assuming blanching is positive risks missing exposure, critical to avoid in ensuring accurate tuberculosis screening, guiding appropriate diagnostic follow-up, and protecting client and public health.
Choice D reason: An elevated, hardened area (induration) at 72 hours indicates a positive Mantoux test, suggesting TB exposure, requiring further evaluation. This is critical for accurate screening, ensuring timely diagnosis, preventing disease spread, and guiding follow-up in clients tested for tuberculosis exposure.

Correct Answer is D
Explanation
Choice A reason: A mobile 24 inches above the crib is too high for a 1-week-old’s vision (8-12 inches is ideal), indicating misunderstanding. A ticking clock is soothing. Assuming mobile placement is correct risks reduced stimulation, critical to avoid in supporting infant development and parental education.
Choice B reason: Propping a bottle with a pillow risks choking or aspiration in a 1-week-old; holding is required. A ticking clock is correct. Assuming propping is safe risks infant safety, critical to prevent in ensuring proper feeding practices and parental education for newborns.
Choice C reason: Avoiding frequent holding risks neglecting bonding and comfort needs in a 1-week-old; responsive care is essential. A ticking clock is soothing. Assuming avoidance is correct risks developmental issues, critical to avoid in supporting infant emotional health and parental caregiving education.
Choice D reason: Placing a ticking clock nearby mimics womb sounds, soothing a 1-week-old, promoting sleep and comfort. This understanding is critical for infant well-being, supporting parental caregiving, ensuring a calming environment, and fostering healthy development in the early newborn period at home.
Correct Answer is D
Explanation
Choice A reason: Increased blood pressure is not an effect of furosemide, which reduces fluid volume, lowering pressure. Weight loss indicates efficacy. Assuming increased pressure is correct risks misinterpreting diuresis, potentially delaying further fluid management, critical to avoid in treating fluid volume excess effectively.
Choice B reason: Decreased pain is unrelated to furosemide’s diuretic action, which targets fluid reduction, evidenced by weight loss. Assuming pain reduction is an indicator risks missing fluid status changes, critical to prevent in ensuring accurate assessment of furosemide’s effectiveness in fluid volume excess treatment.
Choice C reason: Decreased inflammation is not a furosemide effect; it promotes diuresis, reducing fluid, shown by weight loss. Assuming inflammation reduction is relevant risks misjudging medication efficacy, potentially overlooking fluid overload signs, critical to avoid in managing fluid volume excess with diuretic therapy.
Choice D reason: Weight loss indicates furosemide’s effectiveness, as it reduces fluid volume excess through diuresis, decreasing edema and body weight. This is critical for assessing therapeutic response, ensuring fluid balance, preventing complications like heart failure, and guiding further treatment in clients with fluid overload.
