A nurse is reinforcing teaching with a client who will collect stool specimens at home for fecal occult blood testing. Which of the following foods should the nurse instruct the client to avoid for 3 days before the test?

Milk

Whole wheat bread

Red meat

Almonds

Answer and Explanation

The Correct Answer is C

Rationale:

A. Milk: Milk does not interfere with fecal occult blood testing and does not contain substances that cause false-positive results. It can be safely consumed prior to the test without affecting the accuracy of the results.

B. Whole wheat bread: Whole wheat bread is high in fiber, which is actually beneficial when preparing for a fecal occult blood test. It helps promote regular bowel movements but does not lead to false-positive results.

C. Red meat: Red meat contains heme, a form of animal blood, which can cause false-positive results on guaiac-based fecal occult blood tests. Avoiding red meat for at least 3 days prior to the test helps reduce the risk of inaccurate results.

D. Almonds: Almonds and other nuts do not contain components that interfere with fecal occult blood testing. They are not known to cause false-positive or false-negative results and are safe to consume before the test.

Correct Answer is D

Explanation

Rationale:

A. "Store ready-to-feed formula at room temperature for up to 4 hours.": Ready-to-feed formula should be used promptly or refrigerated if not used immediately. Leaving it at room temperature for up to 4 hours increases the risk of bacterial growth and contamination.

B. "Warm the bottle of formula by immersing it in a container of warm tap water.": This is a safe and recommended method to gently warm formula without overheating or creating hot spots that could burn the infant’s mouth.

C. "Keep open cans of concentrated formula uncovered and refrigerated.": Open cans of concentrated formula should always be covered to prevent contamination and should be refrigerated promptly after opening.

D. "Discard any formula left in the bottle within 2 hours after beginning feeding.": Formula left in the bottle after feeding should be discarded within 1 to 2 hours to prevent bacterial growth that can cause illness in the infant. This practice helps ensure feeding safety.

A. Beefy, red tongue B. Productive cough with thick mucous C. Facial erythema D. Koplik spots

Correct Answer is C

Explanation

Rationale:

A. Beefy, red tongue: A beefy, red tongue is typically associated with scarlet fever, not pertussis. It results from the streptococcal infection and accompanying inflammatory response, which is unrelated to the bacterial cause and symptom pattern of pertussis.

B. Productive cough with thick mucous: Pertussis, or whooping cough, usually causes a paroxysmal, dry, hacking cough followed by a characteristic "whooping" sound on inspiration. It is not commonly associated with a productive cough containing thick mucus, especially in early and peak stages.

C. Facial erythema: Facial erythema can occur during severe coughing fits in children with pertussis due to the forceful and prolonged nature of coughing episodes. The increased intrathoracic pressure during coughing may lead to flushing or redness of the face.

D. Koplik spots: Koplik spots are small, bluish-white lesions on the buccal mucosa and are an early sign of measles, not pertussis. They are not present in bacterial infections like Bordetella pertussis, which affects the respiratory tract.
