Correct Answer: D

Rationale: The correct answer is D, "Cardiac rate and rhythm." Monitoring cardiac rate and rhythm is crucial before initiating IVIG because bradycardia is a common side effect associated with this therapy. Assessing lung sounds and respiratory status (Choice A) is important, but cardiac monitoring takes precedence due to the risk of bradycardia. Skin integrity and color (Choice B) are important assessments, but they are not directly related to potential complications of IVIG infusion. Neurological status and level of consciousness (Choice C) are also vital assessments, but monitoring cardiac function is more pertinent in this scenario.

Correct Answer: A

Rationale: The correct answer is A. A hemoglobin level of 12 g/dL is an indicator of effective erythropoietin therapy as it shows an increase in red blood cell production. Reticulocyte count (choice B) reflects the bone marrow's response to anemia but does not directly confirm the effectiveness of erythropoietin therapy. Blood pressure (choice C) and serum ferritin level (choice D) are not specific indicators of the effectiveness of erythropoietin therapy for chronic kidney disease.

Correct Answer: A

Rationale: The school classroom is the most suitable setting to increase preadolescents' participation in a health education program. At the age of 10, children are accustomed to the school environment, making it familiar and comfortable for them. This familiarity can help reduce anxiety and increase engagement during the program. Community centers may be less familiar and could pose distractions, potentially reducing participation. Conducting the program at the home of one of the children may lead to unequal access for other participants and may not provide the necessary facilities for an educational session. A local place of worship may not be perceived as a neutral or suitable environment for a health education program, potentially hindering participation.

Correct Answer: D

Rationale: In a client with diabetic ketoacidosis (DKA), urine output of 50 mL in 4 hours indicates oliguria, which is a concerning sign of decreased renal perfusion and potential renal failure. This finding requires immediate intervention to prevent further deterioration of kidney function.\n\nChoice A (Blood glucose of 200 mg/dL) is elevated but not the most urgent concern in this scenario. Choice B (Serum bicarbonate of 20 mEq/L) reflects metabolic acidosis, which is expected in DKA but does not require immediate intervention. Choice C (Blood pressure of 140/90 mm Hg) is slightly elevated but not acutely concerning in the context of DKA.

Correct Answer: B

Rationale: Organizing concerned citizens to contact state representatives is likely the most effective strategy to secure state funding for the local health clinic. By mobilizing a group of citizens who are directly impacted by the clinic's services, the public health nurse can create a strong advocacy group that can influence decision-makers. Option A, running the health clinic economically and promoting its services, may be necessary but does not directly address the funding aspect. Option C, highlighting services to the media, may raise awareness but does not guarantee funding. Option D, hiring a professional lobbyist, may be costly and may not have the same grassroots impact as organizing citizens.
