Correct Answer: B

Rationale: Piaget is indeed credited with the stages of cognitive development. Jean Piaget, a renowned psychologist, proposed a theory of cognitive development that outlines distinct stages through which children develop intellectually. Erikson, Freud, and Lister are not associated with the stages of cognitive development. Erikson is known for his psychosocial stages, Freud for psychosexual stages, and Lister for contributions to the field of medicine.

Correct Answer: B

Rationale: The main purpose of quality improvement in healthcare is to improve patient outcomes by enhancing the quality and safety of healthcare services. Choice A is incorrect because the goal is not to increase healthcare costs but to optimize resources and provide cost-effective care. Choice C is incorrect as the aim is to increase patient satisfaction through better outcomes. Choice D is incorrect as the objective is to reduce hospital stays by improving care efficiency and effectiveness.

Correct Answer: D

Rationale: The correct answer is D: IV bolus, followed by continuous infusion. In the initial treatment of hyperglycemia in a client with diabetic ketoacidosis, insulin is administered via IV bolus to quickly reduce blood glucose levels, followed by a continuous infusion to maintain control. Subcutaneous and intramuscular routes are not used in this situation as they are not rapid or predictable enough to address the acute hyperglycemia seen in diabetic ketoacidosis. IV bolus alone without the continuous infusion may not provide sustained control of blood glucose levels, making choice C incorrect.

Correct Answer: D

Rationale: The post-icteric stage of viral hepatitis is accurately described as the stage where jaundice and dark urine occur due to the accumulation of bilirubin. The resolution of jaundice and normalization of urine color are seen in this stage. Choices A, B, and C are incorrect. In the prodromal stage, symptoms like fatigue and malaise appear before jaundice. The icteric stage is characterized by jaundice, not flu-like symptoms. The pre-icteric stage does not typically involve elevated urine bilirubin levels, as this occurs after the icteric stage.

Correct Answer: C

Rationale: During periods of infection, clients with type 1 diabetes may require more insulin to manage the increased blood glucose levels caused by stress and illness. Insulin needs often rise during infections due to the body's increased resistance to the effects of insulin. Therefore, increasing insulin doses is crucial to maintain blood glucose control. Choices A, B, and D are incorrect. Option A ('No change') is inaccurate because during infections, insulin requirements typically increase. Option B ('Less insulin') is incorrect as the body's increased insulin resistance during infections usually necessitates higher insulin doses. Option D ('Oral antidiabetic agents') is not suitable for type 1 diabetes management as these medications are primarily used for type 2 diabetes.
