A 55-year-old female is about 9 kg (20 lb) over her desired weight. She has been on a “low-calorie” diet with no improvement. Which statement reflects a healthy approach to the desired weight loss? “I need to:
Increase my exercise to at least 30 minutes every day.”
Switch to a low-carbohydrate diet.”
Keep a list of my forbidden foods on hand at all times.”
Buy more organic and less processed foods.”
The Correct Answer is A
Safe, sustainable weight loss emphasizes gradual lifestyle changes: regular physical activity, balanced calorie control, and behavior modification.
Rationale for correct answer:
1. Increase my exercise to at least 30 minutes every day: Regular moderate exercise (about 30 minutes most days) combined with sensible dietary changes supports weight loss, improves metabolic health, and is a recommended, sustainable strategy.
Rationale for incorrect answers:
2. Switch to a low-carbohydrate diet: Low-carbohydrate diets can produce short-term weight loss for some, but they are not universally superior and may be hard to maintain; the healthier recommended approach is balanced calorie reduction plus activity.
3. Keep a list of my forbidden foods on hand at all times: Strictly forbidding foods can promote guilt, bingeing, and an unhealthy relationship with food. A flexible, portion-controlled approach and behavior strategies are preferable.
4. Buy more organic and less processed foods: Choosing less-processed whole foods can help, but “organic” alone does not guarantee lower calories nor ensure weight loss; portion control and overall caloric balance matter most.
Take home points
- Sustainable weight loss - modest, consistent calorie reduction plus regular physical activity (e.g., ~30 min/day) and behavior changes.
- Avoid extreme or rigid dieting rules; focus instead on balanced meals, portion control, and lifestyle patterns one can maintain long term.

Correct Answer is A
Explanation
Enteral nutrition through nasogastric (NG) tubes is a common nursing intervention for patients who cannot eat orally. The stomach acts as a natural reservoir, allowing gradual delivery of nutrients. Understanding the physiologic advantage of gastric feeding helps nurses prevent complications such as dumping syndrome and metabolic imbalances.
Rationale for correct answer:
1. Dumping syndrome: The stomach regulates the flow of food into the small intestine, reducing the risk of rapid emptying that causes diarrhea, cramping, and hypoglycemia.
Rationale for incorrect answers:
2. Duodenal ulcers: NG feeding does not prevent ulcer formation. Ulcers are primarily linked to H. pylori infection, NSAID use, or acid imbalance.
3. Hyperglycemia: Hyperglycemia is more related to the composition of feedings and metabolic regulation, not the site of feeding.
4. Gastric ulcers: Feeding into the stomach does not specifically prevent gastric ulcers.
Take home points:
- The stomach acts as a reservoir that prevents dumping syndrome by regulating nutrient flow.
- NG feeding must be monitored carefully for tolerance, aspiration, and correct placement.

Explanation
Point-of-care blood glucose monitoring must combine infection control, correct technique, and device accuracy. Steps done in the right order reduce false readings and prevent transmission of infection.
Rationale for correct answer:
- (3) Instruct patient to perform hand hygiene with soap and water.
Prevents contamination from sugar or other residues on the fingers, which could give falsely high readings. - (6) Check code on test strip vial.
Ensures the test strips are calibrated correctly for the glucometer. - (1) Press button on meter to confirm match codes.
Confirms that the meter’s internal code matches the strip code for accuracy. - (8) Perform hand hygiene and put on clean gloves.
Protects both nurse and patient from bloodborne pathogens and infection transmission. - (4) Clean patient finger with antiseptic swab.
Disinfects the puncture site. Important: allow to dry to avoid dilution of blood with alcohol. - (7) Holding lancet to finger, press release button on machine.
Obtains capillary blood sample safely and effectively. - (2) Bringing meter to test strip, allow blood drop to wick onto test strip.
Ensures an adequate sample is absorbed by the strip for analysis. - (5) Interpret results and document.
Completes the procedure and ensures accurate communication of results for clinical decision-making.
Take home points:
- Correct sequence matters: code verification comes before gloves and antiseptic.
- Always finish with interpretation and documentation- this closes the loop on safe patient care.
