Correct Answer: D

Rationale: For a client with acute leukemia and a low white blood cell count, preventing exposure to food contaminants is crucial due to immune suppression. Providing foods in sealed single-serving packages helps reduce the risk of contamination. Choice B is incorrect as it introduces the potential of infection from visitors. Choice A, suggesting disposable utensils, is not as effective as sealed containers in preventing food contamination. Choice C, using alcohol for prepping IV sites, is less suitable due to its drying effect and potential for skin breakdown, making sealed packages a better option for food safety.

Correct Answer: B

Rationale: The appropriate action for the registered nurse in this scenario is to report the behavior to the charge nurse. This allows for proper investigation and intervention. Inappropriate actions include notifying the police directly without following the chain of command (Choice A), monitoring without immediate action (Choice C), and confronting the assistant without involving a superior (Choice D). By reporting to the charge nurse, the situation is escalated appropriately within the healthcare setting, ensuring the well-being and safety of the client.

Correct Answer: C

Rationale: The food that should be avoided for a client with diverticulosis is Cucumber salad. Foods with seeds should be avoided as they can aggravate diverticulosis by causing irritation and inflammation in the diverticula. Choices A, B, and D are allowed and even beneficial. Bran cereal and fruit like fresh peaches can help prevent constipation, which is beneficial for individuals with diverticulosis. Yeast rolls are also acceptable unless the client has specific dietary restrictions related to yeast or gluten.

Correct Answer: B

Rationale: The best action for the charge nurse to take is to explore the interaction with the patient care assistant. This step allows for clarification of the situation and direct addressing of the issue. Changing the patient care assistant's assignment (choice A) might be necessary, but understanding the situation should come first. Discussing the matter with the client's family (choice C) as an initial step could escalate the situation. Initiating a group session with the patient care assistant (choice D) could be considered later as a preventive measure to avoid similar incidents in the future.

Correct Answer: D

Rationale: After birth, newborns can lose weight due to meconium stool, loss of extracellular fluid, and the initiation of breastfeeding. This weight loss is a normal and expected physiological process, and infants can lose up to 10% of their birth weight during this period. There is no indication of dehydration (polyuria), hypoglycemia (lack of glucose), or allergy to the formula as reasons for weight loss in newborns. Therefore, answers A, B, and C are incorrect. Answer D provides the most accurate explanation for the observed weight loss in the newborn.
