Correct Answer: D

Rationale: The correct answer is D, Pinworms. Pinworms are a common cause of itching around the anal area, especially at night, in young children. Scratching the bottom and bedwetting can be indicative of a pinworm infection. Allergies (Choice A) are less likely given the symptoms described. Scabies (Choice B) may cause itching but is less common in causing bedwetting. Regression (Choice C) is not a common cause of these specific symptoms in a 3-year-old child.

Correct Answer: A

Rationale: Encouraging the client to use an incentive spirometer regularly is crucial in preventing postoperative complications after abdominal surgery. This action helps prevent atelectasis by promoting lung expansion and improving air exchange in the lungs, reducing the risk of respiratory complications. Assisting the client in ambulating early is important for preventing issues like deep vein thrombosis but may not directly address respiratory concerns postoperatively. Positioning the client in high Fowler's position can help with respiratory distress but is not as specific to preventing postoperative respiratory complications as using an incentive spirometer. While encouraging the client to cough and deep breathe is generally beneficial for lung expansion, using an incentive spirometer is more effective and targeted in preventing atelectasis after abdominal surgery.

Correct Answer: B

Rationale: The correct answer is B. Rheumatic fever often follows a strep throat infection, which is why the nurse should suspect this association. Strep throat is caused by Group A Streptococcus bacteria, which can trigger an abnormal immune response leading to rheumatic fever. Choices A, C, and D are incorrect because chickenpox, ear infections, and fungal skin infections are not typically associated with rheumatic fever.

Correct Answer: C

Rationale: The correct answer is 'C: Justice.' Justice in healthcare ethics involves fairness and providing equal treatment to all individuals in similar situations. In this scenario, ensuring that all clients waiting for a kidney transplant meet the same qualifications aligns with the principle of justice by offering equal opportunities for transplantation. Choice A, 'Fidelity,' pertains to keeping promises and being loyal to patients, not the equal treatment of individuals. Choice B, 'Autonomy,' refers to respecting patients' rights to make decisions about their own care, which is not directly related to the equal qualifications for kidney transplants. Choice D, 'Nonmaleficence,' focuses on the obligation to do no harm, which is important in healthcare but not the primary ethical principle demonstrated in this scenario.

Correct Answer: A

Rationale: Filling the ice bag two-thirds full is the correct action as it ensures the effectiveness of the ice application while allowing some space for the ice to move and conform to the injury. Choice B is incorrect because the ice bag should be applied with a barrier like a cloth to prevent direct contact with the skin, which can lead to ice burns. Choice C is wrong as ice should typically be applied for 20 minutes at a time to avoid tissue damage. Choice D is also incorrect as ice is preferred over frozen gel packs for immediate sports injury management.
