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
It can also increase the risk of denture stomatitis and pneumonia.
Dentures should be removed overnight and soaked in a denture-cleansing solution.
Choice A is wrong because rinsing dentures after meals can help remove food debris and prevent plaque buildup.
Choice B is wrong because soaking dentures in water after removal can prevent them from drying out and losing their shape.
However, water alone is not enough to disinfect dentures, so a denturecleansing solution should also be used.
Choice C is wrong because applying an adhesive to seal dentures in place can improve the fit and comfort of dentures.
However, adhesive should not be used as a substitute for poorly fitting dentures, and any excess adhesive should be removed by brushing.
Correct Answer is D
Explanation
The correct answer is D. Using two gloved fingers to open the client’s mouth for cleaning.
Choice A rationale:
Lowering the side rail on the side of the bed where the AP will stand is necessary for safe access to the client. However, the AP should ensure the opposite side rail is up to prevent the client from falling.
Choice B rationale:
Using an oral care sponge swab moistened with cool water is an appropriate method for cleaning the mouth of an unconscious client. It helps maintain oral hygiene and comfort.
Choice C rationale:
Wearing clean gloves is essential for infection control and is a standard practice when performing mouth care to protect both the client and the caregiver.
Choice D rationale:
Using two gloved fingers to open the client’s mouth is not recommended as it can cause injury to the caregiver if the client bites down reflexively. Instead, a padded tongue blade should be used to gently open the mouth.
