A 45-year-old male with Type 2 Diabetes Mellitus visits the clinic. He has a BMI of 32 and reports consuming large portions of pasta and bread. Which of the following medical nutrition therapy (MNT) goals is the primary initial focus for this patient to improve glycemic control?

Achieve a 5-10% weight loss through calorie reduction and portion control.
Eliminate all carbohydrates from the diet immediately.
Switch to a high-protein, ketogenic diet exclusively.
Start insulin therapy to cover his current carbohydrate intake.

View Answer & Explanation

Correct Answer: Option A -

Achieve a 5-10% weight loss through calorie reduction and portion control.

Explanation:

According to standard MNT guidelines (and texts like Roth), moderate weight loss (5-10%) is the primary goal for overweight patients with T2DM as it significantly improves insulin sensitivity and glycemic control. Eliminating carbs is not sustainable or recommended; portion control is key.

A school nurse is managing a student with Type 1 Diabetes who becomes shaky and sweaty before lunch. A blood glucose check reveals a level of 60 mg/dL. What is the most appropriate immediate intervention using the '15-15 Rule'?

Give the student a chocolate bar due to its high fat content.
Administer 15 grams of fast-acting carbohydrates (e.g., 4 oz juice) and recheck in 15 minutes.
Provide a turkey sandwich with whole wheat bread.
Send the student to the cafeteria to eat lunch immediately.

View Answer & Explanation

Correct Answer: Option B -

Administer 15 grams of fast-acting carbohydrates (e.g., 4 oz juice) and recheck in 15 minutes.

Explanation:

Hypoglycemia (blood glucose < 70 mg/dL) requires immediate treatment with the 15-15 Rule: Consume 15g of simple carbs (juice, glucose tablets), wait 15 minutes, and recheck. Chocolate contains fat which delays absorption; a sandwich is too slow.

A patient with End-Stage Renal Disease (ESRD) on hemodialysis complains of severe itching and fatigue. Lab results show elevated serum phosphorus. Which of the following foods should the patient be instructed to limit?

White rice and green beans
Apples and grapes
Dairy products like milk and hard cheeses
Olive oil and unsalted butter

View Answer & Explanation

Correct Answer: Option C -

Dairy products like milk and hard cheeses

Explanation:

Dairy products are high in phosphorus. In ESRD, the kidneys cannot excrete excess phosphorus, leading to hyperphosphatemia (itching, bone damage). MNT for renal patients restricts high-phosphorus foods.

A 68-year-old female is admitted with an exacerbation of Congestive Heart Failure (CHF). She has 3+ pitting edema. The dietician recommends a diet restriction to help manage her fluid retention. What is the standard sodium restriction often prescribed for this condition?

4000 mg/day
3000 mg/day
2000 mg/day or less
Sodium restriction is not necessary for CHF.

View Answer & Explanation

Correct Answer: Option C -

2000 mg/day or less

Explanation:

CHF patients retain fluid. Sodium restriction (typically 2000 mg/day or 2g/day) helps reduce fluid retention and edema. Higher intakes exacerbate symptoms.

A client has recently been diagnosed with Celiac Disease. Which of the following lunch options is safe for them to consume?

Whole wheat wrap with grilled chicken
Barley soup with vegetables
Quinoa salad with grilled salmon and olive oil dressing
Rye bread sandwich with turkey

View Answer & Explanation

Correct Answer: Option C -

Quinoa salad with grilled salmon and olive oil dressing

Explanation:

Celiac disease requires a strictly Gluten-Free diet. Wheat, Barley, and Rye contain gluten. Quinoa is a naturally gluten-free grain.

A patient with Diverticulosis asks for dietary advice to prevent complications. Which dietary modification is most appropriate?

Low fiber diet to rest the bowel
High fiber diet with adequate fluid intake
Liquid diet only
Avoidance of all seeds and nuts

View Answer & Explanation

Correct Answer: Option B -

High fiber diet with adequate fluid intake

Explanation:

For Diverticulosis (the asymptomatic condition), a high fiber diet is recommended to prevent constipation and diverticula formation. (Contrast with Diverticulitis, where low fiber is used during acute inflammation).

A patient with Irritable Bowel Syndrome (IBS) is advised to follow a Low-FODMAP diet. Which of the following foods should be avoided during the elimination phase?

Bananas and blueberries
Carrots and cucumbers
Onions and garlic
Maple syrup and hard cheese

View Answer & Explanation

Correct Answer: Option C -

Onions and garlic

Explanation:

Onions and garlic are high in fructans (a type of FODMAP) and are common triggers for IBS symptoms. The other options are generally low-FODMAP.

A patient with Chronic Kidney Disease (Stage 3) who is not on dialysis asks about protein intake. What is the general recommendation to preserve kidney function?

High protein intake (>1.5 g/kg) to build muscle.
Moderate restriction (0.6 - 0.8 g/kg) to reduce nitrogenous waste.
No restriction on protein is needed until Stage 5.
Protein-free diet.

View Answer & Explanation

Correct Answer: Option B -

Moderate restriction (0.6 - 0.8 g/kg) to reduce nitrogenous waste.

Explanation:

In predialysis CKD, restricting protein to 0.6–0.8 g/kg helps slow the progression of renal damage and reduces the buildup of urea (nitrogenous waste). Once on dialysis, protein needs increase.

A 50-year-old male with hypertension is starting the DASH diet. Which of the following nutrient profiles best describes the DASH diet?

High in sodium, low in potassium.
High in fruits, vegetables, and low-fat dairy; low in saturated fat and sodium.
High in protein and fat, low in carbohydrates.
Exclusively plant-based with no animal products.

View Answer & Explanation

Correct Answer: Option B -

High in fruits, vegetables, and low-fat dairy; low in saturated fat and sodium.

Explanation:

Dietary Approaches to Stop Hypertension (DASH) emphasizes fruits, vegetables, low-fat dairy, whole grains, and limits saturated fat and sodium.

A chemotherapy patient is experiencing severe neutropenia (low white blood cell count). Which food safety practice is critical for this patient?

Eating fresh, organic salads from a buffet.
Consuming raw sushi to increase protein intake.
Avoiding raw fruits/vegetables unless peeled/cooked and ensuring meat is well-done.
Taking high-dose probiotic supplements.

View Answer & Explanation

Correct Answer: Option C -

Avoiding raw fruits/vegetables unless peeled/cooked and ensuring meat is well-done.

Explanation:

Neutropenic patients are highly susceptible to infection. A low-microbial (neutropenic) diet often excludes raw unpeeled produce, raw meats/fish, and unpasteurized items to minimize pathogen exposure.
