Generally speaking how much time should a nursing assistant wait before reading an occult blood test?

Correct Answer: D

Rationale: The correct answer is D: 5 to 8 minutes. After applying the specimen to the test area, waiting 5 to 8 minutes allows adequate time for the chemical reaction to occur and for the results to develop accurately. Waiting too short of a time may lead to a false negative result, while waiting too long may result in a false positive. Options A, B, and C are incorrect as they do not allow sufficient time for the test to develop accurately, leading to potential inaccurate results and misinterpretation of the test outcome.

Correct Answer: A

Rationale: The correct answer is A: Contusion. A contusion is a type of closed wound caused by blunt force trauma, resulting in damaged blood vessels and surrounding tissues without breaking the skin. This is different from the other choices: B) Puncture, which involves penetration of the skin by a sharp object, C) Incision, which is a deliberate cut made by a sharp object, and D) Laceration, which is a jagged or irregular tear in the skin caused by a sharp object. Therefore, based on the definition of a contusion as a closed wound from blunt force trauma without breaking the skin, it is the correct choice in this scenario.

Correct Answer: C

Rationale: Correct Answer: C - The NA should report changes in the resident's respiratory rate. Rationale: Reporting changes in the resident's respiratory rate is crucial in oxygen therapy monitoring. It helps identify any potential respiratory distress or improvement. This information allows healthcare providers to adjust oxygen levels accordingly and provide appropriate care. Monitoring respiratory rate is a key aspect of ensuring the resident's safety and well-being. Summary of other choices: A: The NA should limit smoking to certain areas. - Smoking should be completely avoided near a resident receiving oxygen therapy to prevent fire hazards. B: The NA should reduce the number of pillows the resident uses. - Adjusting the number of pillows may affect the resident's comfort but does not directly relate to oxygen therapy. D: The NA should use petroleum-based lip balms to help with irritation. - Petroleum-based lip balms are flammable and should be avoided near oxygen therapy.

Correct Answer: C

Rationale: The correct answer is C: Burns. Diminished sensation following a cerebrovascular accident can lead to the inability to feel pain or temperature changes, increasing the risk of burns from hot surfaces or liquids. This is because the individual may not be able to sense when they are being burned, making them more susceptible to injuries. Rashes and warts (Option A) are not directly related to diminished sensation. Decreased urination (Option B) is more likely to be associated with issues in the urinary system rather than diminished sensation. Seizures (Option D) are neurological events that are not directly caused by diminished sensation.

Correct Answer: B

Rationale: The correct answer is B: Remission. Remission refers to the disappearance of signs and symptoms of cancer, indicating a response to treatment. Metastasis (A) is the spread of cancer to other parts of the body, not the disappearance of symptoms. Breakthrough (C) typically refers to the development of new symptoms or complications during treatment. Intervention (D) involves taking action to address a problem, not specifically related to the disappearance of cancer symptoms. Therefore, remission is the most appropriate term for the disappearance of signs and symptoms of cancer.
