Correct Answer: B

Rationale: The correct answer is to administer intravenous insulin and glucose first. This intervention helps drive potassium back into the cells, lowering serum levels effectively. Administering intravenous calcium gluconate (choice A) is used to stabilize cardiac membranes in severe hyperkalemia but does not address the underlying cause. Administering intravenous sodium bicarbonate (choice C) is used in metabolic acidosis, not hyperkalemia. Administering a loop diuretic (choice D) can help eliminate potassium but is not the first-line treatment for hyperkalemia in CKD.

Correct Answer: A

Rationale: The correct answer is A: Anxiety and restlessness. Abruptly stopping corticosteroids can cause adrenal insufficiency, leading to symptoms such as anxiety and restlessness. These symptoms indicate a potential serious complication that requires immediate intervention. Increased bowel movements and abdominal cramping are common side effects of ulcerative colitis and may not warrant immediate intervention. Fever and chills are not typically associated with adrenal insufficiency caused by corticosteroid withdrawal.

Correct Answer: C

Rationale: In a client with chronic kidney disease receiving erythropoietin therapy, elevated blood pressure is the most concerning assessment finding. Erythropoietin can increase red blood cell production, leading to thicker blood, which in turn can elevate blood pressure. Elevated blood pressure in this scenario may indicate worsening hypertension, which requires prompt intervention to prevent complications such as stroke, heart attack, or further kidney damage. Increased fatigue (choice A) is a common symptom in CKD patients and can be expected with erythropoietin therapy. Headache (choice B) can occur but is less concerning than elevated blood pressure in this context. Low urine output (choice D) is a significant finding in CKD, but in a client receiving erythropoietin, elevated blood pressure takes precedence due to its potential for immediate adverse effects.

Correct Answer: C

Rationale: The correct answer is C: Medicare. Title XVII of the Social Security Act of 1965 created the Medicare Program to provide medical insurance for individuals who are 65 years or older, disabled, or have permanent kidney failure. Medicare is the appropriate agency to refer a 66-year-old woman who is retiring and losing her employment-based health insurance. Choice A, the Woman, Infants, and Children program, is not suitable for this scenario as it provides assistance for low-income pregnant women, breastfeeding women, and young children. Choice B, Medicaid, is a program that helps individuals with low income and resources cover medical costs, which may not be applicable to this woman's situation. Choice D, the Consolidated Omnibus Budget Reconciliation Act provision, known as COBRA, allows employees to continue their group health insurance coverage after leaving their job but may not be the best option for this woman in this case.

Correct Answer: D

Rationale: The correct answer is D, 'Bagel with jelly and skim milk.' This choice includes skim milk, a good source of calcium, which is important for osteoporosis management. It also avoids foods that inhibit calcium absorption. Osteoporosis dietary management emphasizes increased calcium intake and reducing foods that hinder calcium absorption. Choice A only provides proteins but lacks calcium. Choice B offers fruits and a bran muffin, but it lacks a good source of calcium. Choice C has granola but misses a significant source of calcium.
