Correct Answer: A

Rationale: The correct answer is A because wearing gloves during all client contact is a key practice in standard precautions to prevent the spread of infection. Gloves act as a barrier to protect both the healthcare worker and the patient from potential pathogens. Choice B is incorrect as cleaning blood spills with soap and water is not sufficient for infection control. Choice C is incorrect because pouring bulk blood and secretions down a drain is a violation of biohazard disposal protocols. Choice D is incorrect as carrying a blood sample in an open basket can lead to potential exposure to bloodborne pathogens.

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Assessing respiratory status is crucial during a choking incident to identify if the resident is unable to breathe. 2. In this scenario, the resident's inability to breathe indicates a life-threatening problem requiring immediate intervention. 3. CPR is initiated based on the assessment of the resident's breathing difficulty, emphasizing the critical nature of identifying a life-threatening issue. 4. The assessment of respiratory status directly informs the nurse's actions to address the immediate danger of choking. Summary: - Choice A is correct as assessing respiratory status helps identify life-threatening issues like choking. - Choice B is incorrect as the primary focus is on immediate intervention, not establishing a database. - Choice C is incorrect as the assessment is not for skill practice but for identifying a critical situation. - Choice D is incorrect as the goal is not to facilitate breathing but to address the immediate life-threatening problem.

Correct Answer: C

Rationale: The correct answer is C: 500 ml. When someone loses 0.5 kg of weight, it is estimated that about 500 ml of fluid has been lost, as 1 kg of body weight is roughly equivalent to 1 liter of fluid. This fluid loss is due to water loss through sweating, breathing, and urine. Choice A (50 ml) is too small of an amount for a significant weight loss. Choice B (750 ml) is too high and would correspond to a larger weight loss. Choice D (75 ml) is also too small to account for a 0.5 kg weight loss.

Correct Answer: B

Rationale: The correct answer is B because nipple discharge and a breast nodule are classic signs of breast cancer. Nipple discharge can be bloody or clear, and a breast nodule is a lump that feels different from the surrounding tissue. Fever (choice A) is not a common sign of breast cancer. Breast changes during menstruation (choice C) are normal hormonal fluctuations. Fever and erythema of the breast (choice D) are more indicative of an infection rather than breast cancer. Therefore, choice B is the most relevant sign of breast cancer among the options provided.

Correct Answer: C

Rationale: The correct answer is C: Night sweats. In Hodgkin's disease category B, the presence of night sweats signifies more advanced disease and higher tumor burden. Night sweats are a B-symptom, along with fever and weight loss, indicating systemic symptoms. Anemia (choice B) and thrombocytopenia (choice D) are not specific to Hodgkin's disease category B and can be present in various other conditions. Fever (choice A) is not exclusive to Hodgkin's disease category B and can occur in many infections and inflammatory conditions. Night sweats are specifically associated with Hodgkin's disease and are a key indicator of disease severity in this context.
