A nurse is preparing to collect a stool specimen from a client for laboratory testing. Which of the following actions should the nurse take when collecting the specimen?

Transfer the specimen to a cup without it touching the outside of the container.

Wait for 4 hr before sending the specimen to the laboratory.

Collect at least 7.62 cm (3 in) of the client's stool.

Avoid collecting the specimen from areas of the stool that contain blood.

Answer and Explanation

The Correct Answer is A

A. Transfer the specimen to a cup without it touching the outside of the container.: This maintains a clean environment and prevents the spread of microorganisms to others.

B. Wait for 4 hr before sending the specimen to the laboratory.: Specimens should be sent to the lab immediately to ensure accurate results, as changes in temperature and pH can degrade the sample.

C. Collect at least 7.62 cm (3 in) of the client's stool.: Usually, 1 inch (2.5 cm) of formed stool or 15–30 mL of liquid stool is sufficient for testing.

D. Avoid collecting the specimen from areas of the stool that contain blood.: Incorrect. If blood, mucus, or pus is present, these areas should be included in the specimen as they are most likely to contain pathogens.

Correct Answer is D

Explanation

A. Bake with white flour.: White flour is refined and low in fiber, which contributes to constipation. Whole-grain flour is preferred.

B. Use a laxative every day.: Daily laxative use can lead to dependency and a "lazy bowel," worsening chronic constipation over time.

C. Take a calcium supplement.: Calcium supplements are actually known to cause or worsen constipation.

D. Consume probiotic sources.: Probiotics (found in yogurt, kefir, or supplements) help regulate gut flora and improve intestinal motility, which can alleviate chronic constipation.

A. History of hyperlipidemia B. History of diabetes mellitus C. Prealbumin level D. Cholesterol level E. Mini Nutritional Assessment screening tool score F. History of malnutrition

Correct Answer is ["B","C","E"]

Explanation

A. History of hyperlipidemia: High lipids do not directly impair the physiological process of wound healing.

B. History of diabetes mellitus: Diabetes impairs healing due to decreased vascular perfusion and the fact that high glucose levels inhibit white blood cell function.

C. Prealbumin level: The client’s level (13 mg/dL) is below the normal range (15–36 mg/dL). Prealbumin is the best indicator of acute nutritional status; low levels indicate a protein deficiency necessary for tissue repair.

D. Cholesterol level: While slightly elevated (210 mg/dL), this is a risk for cardiovascular disease, not a primary factor in delayed wound healing.

E. Mini Nutritional Assessment (MNA) score: A score of 7 (out of 14) indicates that the client is malnourished. Nutritional deficits significantly delay the inflammatory and proliferative phases of healing.

F. History of malnutrition: Adequate protein, vitamins (A and C), and zinc are essential for collagen synthesis. A history of malnutrition suggests poor reserves for the healing process.
