A nurse in a provider’s office performs a fecal occult blood test with a positive result on a client.
Which of the following clients may have a false positive result?
A. A client who has a venous stasis ulcer.
A client who has peripheral hematomas.
A client who underwent a barium swallow study.
A client who takes an iron supplement.
The Correct Answer is C
Correct answer: C
A. A client who has a venous stasis ulcer: This is less likely to cause a false positive result. While ulcers can bleed, the fecal occult blood test is designed to detect small amounts of blood in the stool, not necessarily blood from other sources like venous stasis ulcers.
B. A client who has peripheral hematomas: Peripheral hematomas are typically not related to the fecal occult blood test. They generally wouldn’t affect the results unless there was significant bleeding or if the hematomas were a result of an underlying bleeding disorder.
C. A client who underwent a barium swallow study: This is the most likely to cause a false positive result. Barium used in the study can sometimes appear as a false positive on the test due to its interference with the chemical reactions used to detect blood.
D. A client who takes an iron supplement: Iron supplements can actually cause a false negative result rather than a false positive because they may darken the stool and mask the presence of blood.

Correct Answer is D
Explanation
The correct answer is choice D. Placing a pillow under the client’s flexed leg is part of the Sims’ position, which is a way of lying on the left side, with the right hip and knee bent and the left arm behind the back.
It is used for vaginal and colonic examinations and natural childbirth.
Choice A is wrong because positioning the client’s arms at his sides is not part of the Sims’ position.
The left arm should be behind the back.
Choice B is wrong because elevating the client’s feet with two pillows is not part of the Sims’ position.
The lower leg should be straightened and the upper leg should be bent.
Choice C is wrong because raising the head of the client’s bed to a 30° angle is not part of the Sims’ position.
The bed should be flat or slightly tilted.
Correct Answer is D
Explanation
The correct answer is choice D. “I’ll think about my grandfather’s farm to reduce pain.” This statement indicates an understanding of guided imagery, which is a relaxation technique that aims to help lower the levels of stress hormones and pain perception by imagining a scene that involves each of the senses and positive emotions.
Guided imagery can help to distract from pain signals and reduce anxiety, which can also contribute to pain.
Choice A is wrong because it does not involve creating a specific imagined reality, but rather noticing the sensation of muscle tension, which may increase awareness of pain.
Choice B is wrong because it does not involve using all of the senses and emotions, but rather listening to music, which may be relaxing but not as effective as guided imagery for pain relief.
Choice C is wrong because it does not involve imagining a scene, but rather using focused breathing to control pain, which is another relaxation technique but not guided imagery.
