NCLEX-PN Test #15 3

Question 1

A client with chronic kidney disease (stage 4) is placed on a renal diet. Which combination of foods is appropriate for this diet?

Accepted Answer

White rice, apple, and small portion of chicken (no added salt)

Answer

The renal diet restricts potassium (no bananas, oranges, tomatoes, potatoes, spinach), phosphorus (limit dairy, nuts, whole grains), sodium, and often protein and fluid. White rice, apples, and small portions of lean protein with no added salt meet renal diet restrictions. Dairy (high phosphorus), spinach (high potassium), and oranges (high potassium) are restricted.

Question 2

A client recovering from a myocardial infarction is being counseled on a heart-healthy diet. Which dietary change has the greatest impact on reducing LDL cholesterol?

Accepted Answer

Replacing saturated and trans fats with unsaturated fats and increasing soluble fiber

Answer

Replacing saturated fats (found in red meat, butter, full-fat dairy) and trans fats with unsaturated fats (olive oil, nuts, avocado) and increasing soluble fiber (oats, legumes, apples) has the most evidence-based impact on reducing LDL cholesterol. Dietary cholesterol restriction has less impact on serum cholesterol than saturated fat reduction.

Question 3

The nurse is caring for a post-operative client with a nasogastric tube. Tube feedings are running. Which position best prevents aspiration?

Accepted Answer

Head of bed elevated 30–45 degrees

Answer

Elevating the head of bed to 30–45 degrees (semi-Fowler's) during and for 30–60 minutes after tube feedings reduces aspiration risk by using gravity to facilitate gastric emptying and minimize reflux. Flat/supine and Trendelenburg positions dramatically increase aspiration risk.

Question 4

A client with iron-deficiency anemia is prescribed ferrous sulfate (iron supplement). Which food enhances iron absorption?

Accepted Answer

A glass of orange juice (vitamin C)

Answer

Vitamin C (ascorbic acid) converts dietary non-heme iron (ferric to ferrous form), significantly enhancing intestinal absorption of iron. It should be taken at the same time as the iron supplement. Calcium, tannins (tea, coffee), and high-fiber foods inhibit iron absorption and should be avoided with iron supplementation.

Question 5

A client with celiac disease asks what foods must be permanently eliminated from their diet. Which food group must be strictly avoided?

Accepted Answer

Foods containing gluten: wheat, barley, and rye

Answer

Celiac disease is an autoimmune condition triggered by gluten — a protein in wheat (including spelt, kamut), barley, and rye. Strict, lifelong elimination of these grains is the only treatment. Rice, corn, quinoa, and potatoes are safe. Some clients have secondary lactose intolerance during active disease, but not all require permanent dairy restriction.
