Correct Answer: C

Rationale: The correct answer is C: 125 mL/h. To calculate the infusion rate per hour, we divide the total volume (1000 mL) by the total time in hours (8 hours). 1000 mL / 8 hours = 125 mL/h. This ensures a consistent and accurate infusion rate throughout the 8-hour period. Choice A (80 mL/h) is incorrect because it underestimates the infusion rate. Choice B (100 mL/h) is incorrect because it does not divide the total volume by the total time correctly. Choice D (150 mL/h) is incorrect because it overestimates the infusion rate.

Correct Answer: A

Rationale: Step 1: Type A blood has been associated with a slightly higher risk of developing gastric cancer compared to other blood types. Step 2: The nurse mentioned a 10% increase in risk, which aligns with the increased risk associated with Type A blood. Step 3: Type AB and Type B blood do not have the same increased risk for gastric cancer as Type A blood. Step 4: Type O blood is actually associated with a lower risk of gastric cancer compared to Type A blood. Step 5: Therefore, the correct answer is A: Type A blood.

Correct Answer: C

Rationale: The correct answer is C, hyperglycemia and hypokalemia. Hyperglycemia can occur in adult clients due to various factors such as diabetes or stress. Hypokalemia can be a consequence of hyperglycemia or other conditions leading to potassium loss. Monitoring for these metabolic complications is essential to ensure the client's well-being. Other choices are incorrect because hypoglycemia and hypercalcemia (choice A) are less likely to occur concurrently in adult clients. Hyperglycemia and hyperkalemia (choice B) are less common as hyperkalemia is usually associated with renal dysfunction. Hyperkalemia and hypercalcemia (choice D) are less likely to be monitored together as they are not commonly seen in the same clinical context.

Correct Answer: C

Rationale: The correct answer is C. Washing feet in hot water is not part of diabetic foot care as it can lead to burns or skin damage. A: Properly fitting shoes help prevent injuries. B: Trimming toenails straight reduces risk of ingrown nails. D: Wearing shoes on hot surfaces protects feet from burns or injuries. Overall, C is incorrect due to its potential harm to the client's feet.

Correct Answer: D

Rationale: The correct answer is D: Chronic ache or pain. Persistent cough and chronic ache or pain are both common warning signs of cancer. Chronic pain can be a symptom of various types of cancer, signaling the presence of a tumor or cancerous growth. It is important for the client to seek medical evaluation to rule out any underlying serious condition. A: Persistent nausea is not typically considered a common warning sign of cancer. While it can be a symptom in certain types of cancer or due to treatment side effects, it is not as prominent as chronic ache or pain. B: Indigestion is a common symptom that can be caused by various non-cancer-related issues such as dietary habits, stress, or gastrointestinal disorders. It is not typically considered a direct warning sign of cancer. C: Rash is generally not a common warning sign of cancer. Rashes are more commonly associated with skin conditions, allergic reactions, or infections rather than being an indicator of cancer.
