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. Waiting 5 to 8 minutes allows sufficient time for the chemical reaction to occur in the occult blood test, providing accurate results. Waiting too short of a time (A, B, C) may lead to false negatives or positives as the reaction may not be complete. Therefore, the nursing assistant should wait 5 to 8 minutes to ensure the test is reliable and accurate.

Correct Answer: A

Rationale: The correct answer is A: Contusion. A contusion is a closed wound caused by blunt force trauma, leading to bruising and tissue damage without breaking the skin. Choice B, Puncture, involves penetration of the skin by a sharp object. Choice C, Incision, is a deliberate cut made with a sharp object. Choice D, Laceration, is a jagged cut caused by a sharp object tearing the skin. Therefore, the correct answer is A as it specifically refers to a closed wound resulting from blunt force trauma.

Correct Answer: C

Rationale: The correct answer is C because reporting changes in the resident's respiratory rate is crucial in monitoring the effectiveness of oxygen therapy and detecting any potential issues. This allows for prompt intervention if needed. A: This choice is incorrect as limiting smoking to certain areas does not directly relate to caring for a resident receiving oxygen therapy. B: Reducing the number of pillows may or may not be necessary for a resident on oxygen therapy, but it is not a specific guideline for their care. D: Using petroleum-based lip balms can be dangerous near oxygen therapy as they are flammable, posing a risk to the resident.

Correct Answer: C

Rationale: The correct answer is C: Burns. Diminished sensation in a resident with a cerebrovascular accident can lead to an inability to feel pain or temperature changes, increasing the risk of burns from hot surfaces or liquids. This is due to impaired sensation, making the individual unaware of potential dangers. Rashes and warts (Choice A) are unrelated to diminished sensation. Decreased urination (Choice B) is more commonly associated with kidney or urinary tract issues. Seizures (Choice D) are not directly related to diminished sensation but may be a complication of a cerebrovascular accident.

Correct Answer: B

Rationale: The correct answer is B: Remission. Remission refers to the disappearance of signs and symptoms of cancer. It does not imply that cancer has been cured, but rather that the disease is under control. Metastasis (A) is the spread of cancer to other parts of the body. Breakthrough (C) typically refers to a sudden development or improvement, not the disappearance of cancer signs. Intervention (D) involves medical treatment or action taken to address a health issue, not the disappearance of cancer signs.
