101Question
A client wants to feed the beneficial bacteria that already live in the colon. Which statement shows the client understands prebiotic foods?
- “I will add oats, beans, and onions to my meals.”
- “I will eat mostly refined grains, which feed gut bacteria best.”
- “I will take a daily laxative to move the bacteria along faster.”
- “I will drink diet soda with every meal to balance gut bacteria.”
Show the answer and explanation
Answer: A. “I will add oats, beans, and onions to my meals.”
Topic: prebiotic foods
Prebiotics are fibers and resistant starches that colon bacteria ferment, as found in oats, beans, onions, garlic, and underripe bananas. Refined grains lack this fiber, laxatives do not feed bacteria, and diet soda has no prebiotic value.
Why the others are wrong
- B – Refined grains have the fiber removed.
- C – Laxatives do not nourish bacteria.
- D – Diet soda provides no fermentable fiber.

102Question
The caregiver of a school-age child with sickle cell disease asks what daily habit helps prevent pain episodes. Which response is best?
- Encourage fluids all day, with extra during hot weather, fever, or exercise.
- Keep fluid intake low to avoid swelling in the joints.
- Offer fluids only with meals so intake stays predictable.
- Give iron-fortified foods daily because iron deficiency is the main trigger for pain episodes.
Show the answer and explanation
Answer: A. Encourage fluids all day, with extra during hot weather, fever, or exercise.
Topic: hydration in sickle cell disease
Dehydration raises blood viscosity and encourages sickling, so steady fluid intake, with extra during heat, fever, or exertion, lowers the risk of vaso-occlusive pain. Many clients are iron-overloaded from transfusions, so iron is not given routinely.
Why the others are wrong
- B – Restricting fluids promotes sickling.
- C – Meal-only fluids are not enough between meals.
- D – Routine iron is not indicated and can add to iron overload.

103Question
A client who follows a strict vegan diet has fatigue, pale skin, and a mean corpuscular volume above normal. Which teaching is most appropriate?
- Eat more spinach and raisins to supply the missing iron.
- Rely on leafy greens alone, because plants contain enough B12.
- Add soy protein to meals to correct the anemia.
- Take a vitamin B12 supplement or eat B12-fortified foods.
Show the answer and explanation
Answer: D. Take a vitamin B12 supplement or eat B12-fortified foods.
Topic: vitamin B12 in a vegan diet
Vitamin B12 occurs naturally almost only in animal foods, so strict vegans need a supplement or fortified foods. A high mean corpuscular volume with fatigue suggests macrocytic anemia from B12 or folate deficiency rather than iron deficiency.
Why the others are wrong
- A – Iron deficiency causes small cells, not large ones.
- B – Plants do not provide reliable B12.
- C – Soy protein does not supply B12.

104Question
A client with a stage 3 pressure injury has been eating about a quarter of each meal. Which nursing action best supports wound healing?
- Withhold between-meal snacks so the client is hungrier at the next scheduled mealtime.
- Offer a protein supplement between meals and ask for a dietitian assessment.
- Change to a clear liquid diet to reduce the effort of eating.
- Encourage low-fat foods only to keep the wound site dry.
Show the answer and explanation
Answer: B. Offer a protein supplement between meals and ask for a dietitian assessment.
Topic: nutrition for wound healing
Healing raises protein and energy needs. When meal intake is poor, protein-rich supplements between meals and a dietitian-guided plan raise intake. Withholding snacks or limiting to clear liquids reduces nutrient intake further.
Why the others are wrong
- A – Withholding snacks lowers total intake.
- C – Clear liquids are low in protein and energy.
- D – Fat intake is not related to wound dryness and low-fat-only choices cut energy.

105Question
A client with early cognitive decline usually snacks on pastries and white-bread sandwiches. Which change should the nurse suggest?
- Remove all carbohydrate from the diet and eat mainly meat, cheese, and eggs to stay full.
- Switch to diet beverages and sugar-free sweets.
- Replace the refined items with whole-grain bread, fresh fruit, and vegetables.
- Skip snacks entirely and eat one meal daily.
Show the answer and explanation
Answer: C. Replace the refined items with whole-grain bread, fresh fruit, and vegetables.
Topic: carbohydrate quality and cognition
Diets rich in fiber-containing complex carbohydrates from whole grains, fruit, and vegetables are associated with better brain health than diets high in refined carbohydrate. Eliminating carbohydrate or skipping meals is unbalanced.
Why the others are wrong
- A – Eliminating carbohydrate is unbalanced and unnecessary.
- B – Sweetener swaps do not improve nutrient quality.
- D – Skipping meals risks undernutrition in an older client.

106Question
A client with Alzheimer disease eats poorly, and the daughter asks why a daily multivitamin cannot replace meals. Which response is best?
- “A multivitamin supplies everything that food does, so it can replace meals when appetite is poor, though it is harder to remember to give.”
- “Whole foods supply fiber and nutrient combinations that pills do not, so a supplement should support meals, not replace them.”
- “Supplements are not allowed with the medicines used for dementia.”
- “Multivitamins are dangerous for older adults and should be avoided.”
Show the answer and explanation
Answer: B. “Whole foods supply fiber and nutrient combinations that pills do not, so a supplement should support meals, not replace them.”
Topic: supplements versus food in dementia
Foods provide fiber, phytochemicals, and nutrients in forms and combinations that supplements cannot reproduce, and the strongest evidence for brain health comes from overall dietary pattern. A multivitamin may fill gaps but is not a substitute, and it is not unsafe or forbidden in general.
Why the others are wrong
- A – It claims a multivitamin equals food, which is false.
- C – There is no general ban with dementia drugs.
- D – Standard multivitamins are generally safe; blanket warnings are inaccurate.

107Question
A client with a new diagnosis of multiple sclerosis, age 54, asks the nurse if a special diet will control symptoms. Which response is best?
- “A strict ketogenic diet is the proven way to prevent relapses.”
- “Avoiding all gluten and dairy has been shown to stop the disease from progressing, so start both right away.”
- “No diet is proven to treat MS, so eat a balanced, heart-healthy diet and ask your neurologist about special diets.”
- “Diet does not matter in MS, so eat whatever you like.”
Show the answer and explanation
Answer: C. “No diet is proven to treat MS, so eat a balanced, heart-healthy diet and ask your neurologist about special diets.”
Topic: diet and multiple sclerosis
Research has not established any specific diet that treats MS. Because people with MS have a higher risk of vascular disease, a balanced, heart-healthy diet is reasonable, and special diets should be reviewed with the neurologist and dietitian.
Why the others are wrong
- A – No diet is proven to prevent relapses.
- B – Elimination diets are not shown to halt progression.
- D – Diet affects overall health and vascular risk, so dismissal is wrong.

108Question
A client with Parkinson disease is eating lunch with the unlicensed assistive personnel (UAP) when the client begins to drool and cough. The UAP reports this to the nurse. Which action should the nurse take first?
- Stop the meal, sit the client upright, and hold oral intake until a swallow screen is done.
- Tell the UAP to give smaller bites and continue the meal with close observation for further coughing.
- Show the UAP how to suction the mouth and then resume feeding.
- Request an order to start tube feedings with the next meal.
Show the answer and explanation
Answer: A. Stop the meal, sit the client upright, and hold oral intake until a swallow screen is done.
Topic: drooling and coughing at meals
Coughing and drooling during meals suggest dysphagia with aspiration risk. The safest first step is to stop oral intake, position upright, and keep the client without oral food and fluids until a swallow screen or speech-language evaluation is completed. Tube feeding is decided after evaluation.
Why the others are wrong
- B – Continuing to feed risks aspiration.
- C – Suctioning does not make eating safe and delays evaluation.
- D – A tube feeding order is premature before evaluation.

111Question
A family member asks why the nurse recommends berries and tea for a client with a neurodegenerative disease. Which explanation is best?
- These foods contain flavonoids, which act as antioxidants and may protect nerve cells.
- Flavonoids replace the dopamine that the brain has lost.
- Flavonoids thin the blood to prevent small clots from forming in the vessels of the brain each day.
- Flavonoids dissolve the protein plaques that damage nerve cells.
Show the answer and explanation
Answer: A. These foods contain flavonoids, which act as antioxidants and may protect nerve cells.
Topic: why flavonoids are recommended
Flavonoids are plant compounds with antioxidant and anti-inflammatory activity, and diets rich in them are linked to slower cognitive decline. They are not drugs: they do not replace neurotransmitters, thin blood, or dissolve plaques.
Why the others are wrong
- B – Flavonoids do not provide dopamine.
- C – Flavonoids are not anticoagulants.
- D – Flavonoids do not dissolve plaques.

- Nutrition counseling and referral
- Smoking cessation status
- Influenza and pneumococcal vaccination status
- Daily fluid intake
Show the answer and explanation
Answer: A. Nutrition counseling and referral
Topic: chart review for a client with COPD
Of the listed items, only the nutrition problem remains unresolved: weight is falling in a client whose breathing already burns extra calories, and the recommended referral was never completed. The other items are documented as met.
Why the others are wrong
- B – Documented as completed.
- C – Documented as current.
- D – Documented as adequate.

113Question
A client with COPD asks how to lower the risk of a serious lung infection. Which teaching should the nurse give?
- Take a leftover antibiotic at the first sign of a cold.
- Get a yearly influenza vaccine and the recommended pneumococcal vaccines.
- Use over-the-counter cough suppressants so that secretions do not build up in the chest.
- Avoid all physical activity during the winter months.
Show the answer and explanation
Answer: B. Get a yearly influenza vaccine and the recommended pneumococcal vaccines.
Topic: preventing infection in COPD
Clients with COPD are at high risk for pneumonia and other respiratory infections, so annual influenza and pneumococcal vaccination are core preventive measures. Leftover antibiotics are inappropriate, suppressing cough retains secretions, and inactivity weakens respiratory muscles.
Why the others are wrong
- A – Self-treatment with leftover antibiotics is unsafe and promotes resistance.
- C – Cough clears secretions, so suppressing it is harmful.
- D – Reduced activity causes deconditioning and does not prevent infection.

114Question
A client hospitalized with pneumonia says, “I am not eating much because I am sick; food will matter when I feel well.” Which response by the nurse is best?
- “Not eating lets your body focus on healing, so a short fast is wise.”
- “Food only affects your weight and has little to do with how well your body fights infection, so do not worry.”
- “You can make up for it by eating one large meal after you go home.”
- “Good nutrition supports your immune defenses and lung repair, so small protein-rich meals now will help.”
Show the answer and explanation
Answer: D. “Good nutrition supports your immune defenses and lung repair, so small protein-rich meals now will help.”
Topic: nutrition and recovery from infection
Illness raises energy and protein needs. Nutrients support immune function and tissue repair, so intake during the infection matters. Small, protein-rich meals are practical when appetite is low.
Why the others are wrong
- A – Fasting reduces the nutrients needed for immune response and repair.
- B – Nutrition strongly influences immune function.
- C – Delay deprives the body of nutrients during peak need.

- Serve three large meals so the client can rest between them.
- Encourage fluids all day and offer small, frequent, protein-rich meals.
- Offer food only when the client asks for it.
Show the answer and explanation
Answer: C. Encourage fluids all day and offer small, frequent, protein-rich meals.
Topic: fluids and meals during pneumonia
Fever and rapid breathing raise fluid and energy needs, and adequate hydration helps thin secretions so they can be cleared. Small, frequent, protein-rich meals are easier to tolerate and support the immune response.
Why the others are wrong
- A – Restriction thickens secretions and risks dehydration.
- B – Large meals are poorly tolerated with low appetite.
- D – Waiting for requests leads to low intake.

117Question
A client with overactive bladder reports urgency and waking three times at night to void. Which plan shows the best understanding of beverage choices?
- Sip water through the day and stop most fluids two to three hours before bed.
- Replace morning coffee with cola to cut back on caffeine.
- Drink a large glass of water at bedtime so that the bladder is flushed clear overnight.
- Add citrus juice with dinner to supply vitamin C.
Show the answer and explanation
Answer: A. Sip water through the day and stop most fluids two to three hours before bed.
Topic: bladder-friendly beverages
Caffeine, carbonation, alcohol, and citrus can irritate the bladder and worsen urgency, and large evening fluid loads increase nocturia. Spreading water across the day and tapering before bed controls symptoms while keeping the client hydrated.
Why the others are wrong
- B – Cola still contains caffeine and carbonation.
- C – A bedtime load worsens nocturia.
- D – Citrus is a bladder irritant.

118Question
A client with a calcium oxalate kidney stone is receiving discharge teaching. Which statement by the client shows that more teaching is needed?
- “I will drink enough fluid each day to make about 2.5 liters of urine, even in cool weather.”
- “I will limit salty processed foods.”
- “I will cut back on spinach and rhubarb.”
- “I will stop eating dairy and other calcium foods so no calcium is left to form stones.”
Show the answer and explanation
Answer: D. “I will stop eating dairy and other calcium foods so no calcium is left to form stones.”
Topic: calcium and oxalate stone prevention
Dietary calcium binds oxalate in the gut, so restricting it can increase oxalate absorption and stone risk. Prevention relies on high fluid intake, limiting sodium and excess animal protein, and moderating oxalate-rich foods while keeping normal calcium intake.
Why the others are wrong
- A – High urine volume dilutes stone-forming minerals.
- B – Sodium increases urine calcium.
- C – These foods are high in oxalate.

121Question
A client with benign prostatic hyperplasia and a weak urinary stream plans to buy an over-the-counter cold remedy. Which advice is best?
- Choose a product containing pseudoephedrine, which relaxes the bladder and helps urine flow better.
- Check with the provider or pharmacist first, because decongestants can cause urinary retention.
- Take any cold remedy but drink less fluid to avoid urgency.
- Products labeled non-drowsy are safe for anyone with prostate enlargement.
Show the answer and explanation
Answer: B. Check with the provider or pharmacist first, because decongestants can cause urinary retention.
Topic: over-the-counter medicines and BPH
Decongestants such as pseudoephedrine tighten smooth muscle in the prostate and bladder neck, and anticholinergic antihistamines weaken bladder contraction, so both can precipitate urinary retention in BPH. The client should ask a pharmacist or provider about safer choices.
Why the others are wrong
- A – Pseudoephedrine worsens outflow.
- C – Restricting fluids does not make the drug safe and risks dehydration.
- D – Non-drowsy labeling says nothing about urinary effects.
