A nurse is providing education to adolescents about healthy food choices. A cookie has 2 g of protein, 12 g of fat, and 30 g of carbohydrates. How many calories does the cookie contain? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["236"]
Identify the calorie content per gram of each macronutrient.
Protein: 4 calories/gram
Fat: 9 calories/gram
Carbohydrates: 4 calories/gram
Calculate the calories from protein.
Calories from protein = 2 g × 4 calories/gram
= 8 calories.
Calculate the calories from fat.
Calories from fat = 12 g × 9 calories/gram
= 108 calories.
Calculate the calories from carbohydrates.
Calories from carbohydrates = 30 g × 4 calories/gram
= 120 calories.
Calculate the total calories in the cookie.
Total calories = Calories from protein + Calories from fat + Calories from carbohydrates
= 8 calories + 108 calories + 120 calories
= 236 calories.
Rounded to the nearest whole number: 236.

Correct Answer is C
Explanation
A. Platelets 130,000/mm³ (150,000 to 400,000/mm³). This value is slightly below normal and indicates mild thrombocytopenia. While it should be monitored, it is not immediately life-threatening and does not typically require urgent intervention in the absence of active bleeding or symptoms.
B. Creatinine 1.3 mg/dL (0.5 to 1.1 mg/dL). This level is slightly elevated and may suggest early renal impairment, which is a concern in clients with diabetes. However, it does not require urgent reporting unless there are signs of acute kidney injury or rapid progression.
C. Glucose 423 mg/dL (74 to 106 mg/dL). This critically high blood glucose level indicates severe hyperglycemia and places the client at immediate risk for complications such as diabetic ketoacidosis (DKA). This finding requires prompt reporting and intervention to prevent further deterioration.
D. HbA1c 9% (4% to 5.99%). This value reflects poor long-term glycemic control and increases the risk of chronic complications, but it does not indicate an acute emergency. It requires follow-up, not immediate action.
