Correct Answer: D

Rationale: Decreased deep tendon reflexes are a critical finding in hypokalemia that indicates severe potassium deficiency affecting neuromuscular function. Immediate intervention is necessary to prevent life-threatening complications such as respiratory failure or cardiac arrhythmias. Muscle weakness, irregular heart rate, and increased urinary output are also associated with hypokalemia but do not pose the same level of urgency as decreased deep tendon reflexes.

Correct Answer: D

Rationale: The correct answer is D: lower relapse rate among participants. A lower relapse rate indicates that participants are successfully quitting smoking and maintaining their cessation, which is the ultimate goal of a smoking cessation program. Increased attendance at support group meetings (choice A) may demonstrate engagement but does not necessarily indicate successful smoking cessation. Similarly, higher sales of nicotine replacement products (choice C) may reflect increased product usage but not necessarily successful smoking cessation. While reducing the number of cigarettes smoked per day (choice B) is a positive change, it does not guarantee successful smoking cessation or long-term abstinence.

Correct Answer: A

Rationale: The correct answer is A: a schedule for blood glucose monitoring. Regular blood glucose monitoring is essential in managing type 1 diabetes as it helps in monitoring blood sugar levels, adjusting treatment plans, and preventing complications such as hypoglycemia or hyperglycemia. Choice B, a list of low-carbohydrate snacks, while important for managing blood sugar levels, is not as critical as consistent blood glucose monitoring. Choice C, a contact list of healthcare providers, though important for emergency situations, is not the most crucial component in managing daily care. Choice D, a log for recording insulin administration, is valuable for tracking insulin doses but does not directly address the immediate need for monitoring blood glucose levels.

Correct Answer: A

Rationale: The correct answer is A: Hemoglobin of 12 g/dL. Erythropoietin therapy stimulates red blood cell production, leading to an increase in hemoglobin levels. A hemoglobin level of 12 g/dL indicates that the therapy is effective in managing anemia associated with chronic kidney disease. Choice B, a reticulocyte count of 1%, is not a direct indicator of the effectiveness of erythropoietin therapy. Choice C, a blood pressure of 130/80 mm Hg, is important to monitor in clients with chronic kidney disease but does not specifically indicate the effectiveness of erythropoietin therapy. Choice D, a serum ferritin level of 100 ng/mL, is related to iron stores in the body and may be monitored during erythropoietin therapy but does not directly reflect the therapy's effectiveness in increasing red blood cell production.
