1. A nurse is reviewing the laboratory findings of an adult client who has a suspected
diagnosis of protein-malnutrition. Which of the following serum proteins has the shortest
half-life and is therefore the most sensitive indicator of acute visceral protein status?
A. Albumin
B. Prealbumin
C. Transferrin
D. Retinol-binding protein
Answer: B
Prealbumin has a half-life of approximately 2 days, making it highly sensitive to acute
changes in nutritional status, whereas albumin has a much longer half-life of roughly 20 days
and reflects long-term trends rather than immediate changes.
2. A nurse is providing dietary teaching to a client who has newly diagnosed chronic kidney
disease (CKD) and is not yet on dialysis. Which of the following nutritional modifications
should the nurse include in the instructions?
A. Increase daily dietary protein intake to 1.5 g/kg
B. Restrict daily sodium and potassium intake
C. Encourage a high-phosphorus diet to prevent bone loss
D. Supplement with megadoses of water-soluble vitamins
Answer: B
In non-dialysis dependent chronic kidney disease, restricting sodium helps manage
hypertension and fluid retention, while potassium restriction prevents hyperkalemia caused by
decreased renal clearance. Protein is typically restricted rather than increased to reduce the
workload on the kidneys.
3. A nurse is caring for an older adult client who exhibits signs of dehydration and
confusion. Which of the following physiological changes associated with aging places this
client at the highest risk for fluid imbalance?
A. Increased glomerular filtration rate
B. Heightened sense of thirst response
C. Decreased total body water percentage
D. Elevated lean muscle mass retention
,Answer: C
Aging is accompanied by a natural decrease in total body water and a blunted thirst
mechanism, which significantly increases the vulnerability of older adults to rapid
dehydration and subsequent cognitive alterations.
4. A nurse is planning care for a client who is receiving continuous enteral nutrition via a
nasogastric tube. Which of the following interventions is essential to prevent the
complication of aspiration?
A. Elevate the head of the bed to at least 30 degrees continuously
B. Flush the tube with 100 mL of sterile water every 2 hours
C. Check residual volumes every 8 hours
D. Warm the formula in a microwave prior to administration
Answer: A
Elevating the head of the bed between 30 and 45 degrees during and for at least one hour after
intermittent feedings, or maintaining it continuously for continuous feeds, is the primary
mechanical barrier against pulmonary aspiration of enteral formula.
5. A nurse is educating a client about healthy lipid consumption to reduce the risk of
cardiovascular disease. Which of the following dietary fats should the nurse encourage the
client to incorporate into their meal planning?
A. Trans fats
B. Saturated fats
C. Monounsaturated fats
D. Hydrogenated vegetable oils
Answer: C
Monounsaturated fats, found in foods such as olive oil, avocados, and various nuts, help
improve blood lipid profiles by lowering low-density lipoprotein cholesterol while maintaining
high-density lipoprotein cholesterol levels.
6. A nurse is assessing a client who has a history of chronic alcohol use disorder and
presents with neurological impairment and ataxia. The nurse should recognize that this
clinical presentation is primarily associated with a deficiency of which of the following
micronutrients?
A. Thiamine (Vitamin B1)
B. Ascorbic acid (Vitamin C)
C. Cobalamin (Vitamin B12)
D. Phylloquinone (Vitamin K)
,Answer: A
Chronic alcohol consumption impairs intestinal absorption and hepatic storage of thiamine,
leading to Wernicke-Korsakoff syndrome, which manifests with acute neurological deficits,
confusion, and ataxia.
7. A nurse is evaluating the effectiveness of nutritional therapy for a client with iron-
deficiency anemia. Which of oral supplement administration practices should the nurse
reinforce to maximize absorption?
A. Take the iron supplement with a glass of whole milk
B. Administer the supplement alongside an orange juice chaser
C. Crush the sustained-release tablets for easier swallowing
D. Take the medication immediately before a heavy evening meal
Answer: B
Ascorbic acid (Vitamin C) creates an acidic environment in the stomach and acts as a
reducing agent, which significantly enhances the bioavailability and intestinal absorption of
non-heme iron supplements.
8. A nurse is caring for a client who is prescribed a low-tyramine diet due to the initiation
of a monoamine oxidase inhibitor (MAOI). Which of the following food selections should
the nurse advise the client to avoid?
A. Fresh steamed white rice
B. Aged cheeses and cured meats
C. Pasteurized skim milk
D. Steamed fresh green beans
Answer: B
Aged cheeses, cured meats, fermented products, and draft beers contain high levels of
tyramine, which can trigger a severe hypertensive crisis when combined with monoamine
oxidase inhibitors due to uninhibited norepinephrine release.
9. A nurse is providing nutritional counseling to a client who is in her first trimester of
pregnancy. Which of the following daily supplement recommendations should the nurse
emphasize to prevent neural tube defects?
A. 400 micrograms of folic acid
B. 1,500 milligrams of calcium
C. 15 milligrams of zinc
D. 5,000 international units of Vitamin A
Answer: A
, Periconceptional and early first-trimester supplementation with at least 400 mcg of folic acid
is critical for the proper closure of the neural tube and the prevention of congenital
malformations such as spina bifida.
10. A nurse is caring for an adolescent client diagnosed with anorexia nervosa who has
recently begun a refeeding protocol. The nurse should closely monitor the client for which
of the following potentially life-threatening electrolyte imbalances?
A. Hypernatremia and hyperchloremia
B. Hypophosphatemia and hypokalemia
C. Hypercalcemia and hypermagnesemia
D. Hyperkalemia and hyponatremia
Answer: B
Refeeding syndrome occurs when starved clients receive nutritional support too quickly,
triggering a sudden shift of electrolytes, particularly phosphorus, potassium, and magnesium,
intracellularly, which can lead to cardiac collapse and neurological failure.
11. A nurse is assessing a client with celiac disease. Which of the following dietary grains
must be permanently eliminated from this client's meal plan?
A. Rice, corn, and quinoa
B. Wheat, rye, and barley
C. Millet, sorghum, and buckwheat
D. Amaranth, teff, and oats (if certified gluten-free)
Answer: B
Celiac disease is an autoimmune enteropathy triggered by the ingestion of gluten, a protein
composite found specifically in wheat, rye, and barley, which causes destructive inflammation
of the small intestinal mucosa.
12. A nurse is designing a weight-management plan for an adult client with a body mass
index (BMI) of 32. Which of the following weekly weight loss goals is considered safe,
realistic, and clinically sustainable?
A. 0.5 to 1 pound per week
B. 1 to 2 pounds per week
C. 3 to 5 pounds per week
D. 6 to 8 pounds per week
Answer: B
