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
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 A
Explanation
Rationale:
A. "You should have a sputum examination every 4 weeks.": Monthly sputum samples are necessary to monitor treatment effectiveness and determine when the client is no longer infectious. Clients typically need three consecutive negative sputum cultures to be considered non-contagious.
B. "You should obtain a chest x-ray every 3 months.": Chest x-rays are not routinely used for frequent follow-up during treatment. They may be used at diagnosis or treatment completion, but monthly sputum cultures are more reliable for monitoring active infection.
C. "You should schedule a tuberculin skin test every 6 months.": A tuberculin skin test is not useful for clients with active TB or for monitoring treatment response. Once a person has tested positive, repeat testing is not recommended due to persistent reactivity.
D. "You should stop taking your antituberculin medication after 2 weeks.": TB treatment requires a prolonged course typically 6 to 12 months. Stopping medication after 2 weeks increases the risk of treatment failure, relapse, and drug resistance, even if symptoms improve.
Correct Answer is B
Explanation
Rationale:
A. "I will position my arms away from my body when pushing an object.": Keeping the arms close to the body provides better leverage and reduces strain on the muscles and joints. Extending arms away increases risk of injury.
B. "I will position my body to face an object, so I avoid twisting: Facing the object directly helps maintain proper spinal alignment and reduces the risk of back injury by minimizing twisting motions during lifting or pushing.
C. "I will position my legs close together before lifting.": Keeping legs close together decreases stability and increases risk of losing balance. A wider stance improves balance and distributes weight evenly during lifting.
D. "I will position objects away from my body before lifting them.": Objects should be held close to the body to reduce strain on the back and arms. Holding objects away increases lever arm forces and injury risk.
