Correct Answer: B

Rationale: The correct answer is B: Asian Americans. Asian Americans have a higher incidence of liver cancer compared to other population groups due to factors such as chronic hepatitis B infection and dietary aflatoxin exposure. Monitoring this group closely is essential for early detection and intervention. Incorrect choices: A: Hispanic - While Hispanics have a higher prevalence of fatty liver disease, the highest risk of liver cancer is not among this group. C: Non-Hispanic Caucasians - Caucasians have a lower incidence of liver cancer compared to Asian Americans. D: Non-Hispanic African-Americans - African-Americans have a lower risk of liver cancer compared to Asian Americans due to differences in risk factors and prevalence of hepatitis B.

Correct Answer: B

Rationale: The nurse sitting at the patient's bedside is using the personal zone of personal space, which ranges from 18 inches to 4 feet. This distance allows for a close interaction suitable for taking a nursing history while maintaining a professional yet personal connection. The socio-consultative zone (A) is 4-12 feet, more appropriate for professional interactions. The intimate zone (C) is 0-18 inches, too close for an initial nursing history. The public zone (D) is 12 feet or more, too distant for a personal conversation.

Correct Answer: C

Rationale: The correct answer is C: Assessing and addressing the patient's emotional needs. This should be prioritized because the patient has undergone a traumatic experience losing their eye due to a workplace accident. Emotions such as fear, anxiety, and grief are common postoperatively. Addressing these emotional needs is crucial for the patient's overall well-being and recovery. Options A, B, and D are important aspects of care but not the priority in this situation. Teaching about eye prostheses, depth perception, and medication regimen can be addressed once the patient's emotional needs are stabilized.

Correct Answer: D

Rationale: The correct answer is D: Mobility. A malignant breast tumor typically lacks mobility due to its fixed attachment to surrounding tissues. This characteristic is concerning for malignancy as it suggests invasive growth. Incorrect answers: A: Nontenderness - Tenderness does not reliably indicate malignancy or benignancy. B: A size of 5 mm - Tumor size alone does not determine malignancy. C: Softness and a regular shape - Malignant tumors are often firm and irregular in shape.

Correct Answer: A

Rationale: The correct answer is A: decreased fibrinogen. In disseminated intravascular coagulation (DIC), there is widespread activation of coagulation leading to consumption of clotting factors like fibrinogen, resulting in decreased levels. Platelets are usually decreased, not increased, in DIC. Hematocrit may be elevated due to hemoconcentration but not directly related to DIC. Thromboplastin time would be prolonged, not decreased, in DIC due to consumption of clotting factors.
