A nurse is preparing to obtain a guaiac smear sample from a client for fecal occult blood testing. Which of the following actions should the nurse plan to take?
Wear sterile gloves when collecting the sample.
Discard samples that contain urine.
Collect three samples from a single bowel movement.
Take the sample from the outer edge of formed stool.
The Correct Answer is B
Choice A reason: While wearing gloves is a standard precaution to prevent contamination and protect the nurse from potential pathogens, the gloves used for collecting a guaiac smear sample do not need to be sterile. Clean, non-sterile gloves are typically sufficient for this procedure.
Choice B reason: It is crucial to discard any samples that contain urine because urine can interfere with the results of the fecal occult blood test (FOBT). The presence of urine can cause false positives due to the peroxidase activity in urine, which can lead to unnecessary further testing.
Choice C reason: Collecting three samples from a single bowel movement is not recommended. Instead, it is advised to collect samples from three separate bowel movements to increase the likelihood of detecting intermittent bleeding, which is common in conditions like colorectal cancer.
Choice D reason: Taking the sample from the outer edge of formed stool is not the best practice. The sample should be taken from different areas of the stool to ensure a representative sample, as blood may not be uniformly distributed throughout the stool.

Correct Answer is B
Explanation
Choice A reason: Papilledema, which is the swelling of the optic disc due to increased ICP, is not typically an early sign. It is usually a later manifestation because it takes time for the pressure to build up and affect the optic nerve.
Choice B reason: Restlessness can be an early sign of increased ICP. As ICP begins to rise, it can cause subtle changes in a person's level of consciousness, leading to agitation or restlessness. This is often one of the first signs that healthcare providers notice when monitoring for changes in neurological status.
Choice C reason: Projectile vomiting may occur with increased ICP, but it is not usually an early sign. It tends to occur after other symptoms such as headache and altered consciousness and is more indicative of significant pressure increases that affect the brainstem.
Choice D reason: Decorticate posturing is a severe sign of brain injury associated with increased ICP but is not an early sign. It indicates significant damage to the brain and is a late and ominous sign in the progression of increased ICP.
Correct Answer is B
Explanation
Choice A reason : While eating fresh fruits and vegetables is generally healthy, it does not specifically indicate an understanding of AIDS-related teaching. Some fruits and vegetables need to be carefully handled to avoid potential infections.
Choice B reason : Wearing gloves and washing hands after changing a cat's litter box is correct as it helps prevent the transmission of infections, such as toxoplasmosis, which can be particularly harmful to individuals with AIDS.
Choice C reason : Taking clothes to the dry cleaners for sterilization is unnecessary and does not reflect an understanding of AIDS-related precautions.
Choice D reason : Wiping up areas soiled with body fluids with alcohol and disposing of the trash is a good practice for infection control, but it is not as directly related to the client's understanding of AIDS-specific precautions as choice b.
