Rationale: When the supervisor allocates nurses to the priority wards in response to the situation of several nurses not reporting due to the Jeepney strike, she is practicing the ethical principle of justice. Justice in healthcare pertains to the fair distribution of resources and the equitable treatment of individuals. By ensuring that nurses are allocated fairly and appropriately to address the urgent needs of the hospital and its patients, the supervisor is upholding the principle of justice. This decision aims to ensure that all patients receive the care they need despite the unexpected staffing shortage.

Correct Answer: D

Rationale: The symptoms described by the patient indicate a potential transfusion reaction, such as a hemolytic reaction or allergic reaction. The immediate action the nurse should take in such a situation is to stop the infusion of the packed red blood cells. This will help prevent further complications and ensure the safety of the patient. After stopping the infusion, the nurse should assess the patient's condition, monitor vital signs, and inform the healthcare team, including the physician, regarding the situation. Once the patient is stable, further investigations can be conducted to determine the cause of the reaction.

Correct Answer: D

Rationale: Restlessness caused by pain often manifests as increased perspiration and constant change of position. When a person is in pain, they may become sweaty or clammy due to increased sympathetic nervous system activity. Additionally, they may constantly shift or fidget in an attempt to find a more comfortable position that can alleviate the pain they are experiencing. Therefore, it is crucial for Nurse Chona to accurately document these behaviors as signs of pain-related restlessness. Difficulty of breathing (Option A), increased respiratory rate and blood pressure (Option B), and increased heart rate (Option C) are more indicative of hypoxia or respiratory distress rather than pain-related restlessness.

Correct Answer: A

Rationale: Acanthosis nigricans is a skin condition characterized by multiple, hyperpigmented, velvety plaques typically seen in flexural areas such as the axillae, neck, and groin. These lesions are often associated with obesity and insulin resistance. The appearance of acanthosis nigricans is distinct from other skin conditions such as seborrheic keratosis, dermatofibroma, and epidermal nevus. Acanthosis nigricans is commonly seen in conditions like obesity, type 2 diabetes, and metabolic syndrome due to the insulin resistance that leads to the overgrowth of keratinocytes.

Correct Answer: A

Rationale: At the concrete operational stage according to Piaget's theory, children typically demonstrate logical thinking abilities and are able to understand and work with concrete objects and events.

These children are able to think logically about concrete events but may still struggle with abstract and hypothetical situations. Therefore, Belle, functioning at the concrete operational stage, would exhibit behaviors such as thinking logically and being able to see possibilities, as described in option A.
