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 D
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 B
Explanation
This type of aphasia is caused by damage to the frontal lobe of the brain, which affects the ability to produce language.
People with expressive aphasia can understand speech and know what they want to say, but they have difficulty saying words or forming sentences.
They may speak in short phrases that require a lot of effort.
Choice A is wrong because receptive aphasia is a type of fluent aphasia that affects the ability to comprehend language.
People with receptive aphasia have difficulty understanding speech and may produce meaningless words or sentences.
Choice C is wrong because global aphasia is the most severe type of aphasia that affects both the production and comprehension of language.
People with global aphasia cannot speak many words and do not understand speech.
They also cannot read or write.
Choice D is wrong because sensory aphasia is not a common term for a type of aphasia.
It may refer to Wernicke’s aphasia, which is another type of fluent aphasia that affects the ability to produce meaningful language.
People with Wernicke’s aphasia can speak fluently but often use incorrect or invented words or phrases.
Correct Answer is D
Explanation
The correct answer is choice D. This type of device is useful for a client who cannot assist.
A mechanical lift is used to transfer residents who cannot support their own weight.
It does not require the client to use upper body strength, as choice A suggests.
The lower end of the sling should go under the client’s thighs, not below the calves, as choice B states.
The sides of the sling are not for the client to hold on to, but for the caregiver to attach to the hooks on the lift, as choice C implies.
Therefore, choices A, B and C are wrong because they do not reflect the proper use of a mechanical lift.
