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.

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: B

Rationale: The correct answer is B: Hemoglobin. Epoetin alfa (Epogen) is a medication commonly used in clients with chronic kidney disease to stimulate red blood cell production. Monitoring hemoglobin levels is crucial to assess the effectiveness of epoetin alfa therapy. Hemoglobin levels reflect the oxygen-carrying capacity of the blood and indicate if the medication is successfully treating anemia associated with chronic kidney disease. Option A, serum creatinine, is a marker of kidney function, not the primary indicator of epoetin alfa effectiveness. Option C, blood urea nitrogen (BUN), is a measure of kidney function and hydration status. Option D, platelet count, assesses clotting ability and is unrelated to monitoring the effectiveness of epoetin alfa in treating anemia in chronic kidney disease.

Correct Answer: D

Rationale: The correct answer is D: Normal breath sounds. In the scenario described, the nurse hears normal bronchovesicular breath sounds, which are moderate in intensity and resemble blowing as air moves through the larger airways during inspiration and expiration. Crackles (choice A) are typically heard in conditions like heart failure or pneumonia and are not present in this case. Rhonchi (choice B) are low-pitched, continuous sounds often associated with conditions like chronic bronchitis or bronchiectasis. Friction rub (choice C) is a grating sound usually heard in conditions like pleurisy or pericarditis, which is not the case here where normal breath sounds are heard.

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.
