ATI Nutrition Practice A

1. Which of the following is a good food source of iodine?

A. Seafood
B. Lettuce
C. Broccoli
D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.

2. Nutrients that may help decrease high blood pressure levels include:

A. magnesium and sodium
B. protein and monounsaturated fat
C. calcium and potassium
D. dietary fiber and plant sterols

Correct answer: C

Rationale: Calcium and potassium play vital roles in regulating blood pressure, with potassium helping to balance the negative effects of sodium.

3. A nurse is teaching an in-service about manifestations of hypoglycemia to a group of newly licensed nurses. Which of the following should the nurse include in the teaching?

A. Blurred vision
B. Vomiting
C. Kussmaul respirations
D. Bradycardia

Correct answer: A

Rationale: Corrected Rationale: Blurred vision is a common symptom of hypoglycemia and should be included in the teaching. Other manifestations like vomiting, Kussmaul respirations, and bradycardia are not typically associated with hypoglycemia. Vomiting is more commonly seen in conditions like food poisoning or gastrointestinal issues. Kussmaul respirations are deep and rapid respirations seen in metabolic acidosis, not hypoglycemia. Bradycardia is usually not a manifestation of hypoglycemia; tachycardia is more commonly associated with low blood sugar levels.

4. What is the glomerular filtration rate for patients with stage 5 chronic kidney disease (CKD)?

A. Less than 15 mL/min/1.73 m²
B. Less than 30 mL/min/1.73 m²
C. Less than 90 mL/min/1.73 m²
D. Less than 125 mL/min/1.73 m²

Correct answer: A

Rationale: In patients with stage 5 chronic kidney disease (CKD), also known as end-stage renal disease, the kidney function is significantly compromised. This severe condition is characterized by a glomerular filtration rate (GFR) of less than 15 mL/min/1.73 m², as correctly stated in choice A. Choices B, C, and D suggest higher GFR values, which are not indicative of stage 5 CKD. Specifically, a GFR of less than 30 mL/min/1.73 m² indicates stage 4 CKD, less than 90 mL/min/1.73 m² signifies stage 3 CKD, and a typical healthy individual usually has a GFR of around 125 mL/min/1.73 m², which is far above the GFR for stage 5 CKD.

5. A nurse at a health fair is assessing the weight status of four clients. Which of the following clients is classified as overweight?

A. A female client who has a body mass index of 24
B. A male client who has a body mass index of 29
C. A female client who has a waist circumference of 101.6 cm (40 in)
D. A male client who has a waist circumference of 96.52 cm (38 in)

Correct answer: B

Rationale: A body mass index (BMI) of 25 or higher is classified as overweight. Choice B, a male client with a BMI of 29, falls into the overweight category. Choice A, a female client with a BMI of 24, is within the normal range. Choices C and D provide information on waist circumference, which is not sufficient to determine if a client is overweight or not, as waist circumference alone does not provide the overall picture of weight status compared to BMI.
