Question 1 of 5
A stage 1 pressure injury has skin that is
Correct Answer: D
Rationale: The correct answer is D - Red or a different color than the surrounding area. In a stage 1 pressure injury, the skin appears red or a different color due to localized damage. This indicates early tissue damage without skin breakdown. Choice A is incorrect as it refers to a stage 2 pressure injury where the skin is nonintact. Choice B describes a stage 3 or 4 pressure injury with a deep crater. Choice C is not accurate as deep purple color is not typically associated with stage 1 pressure injuries.
Question 2 of 5
The basic working unit of the nervous system is the
Correct Answer: C
Rationale: The correct answer is C: Neuron. Neurons are the basic working units of the nervous system because they are specialized cells that transmit information through electrical and chemical signals. Neurons have a cell body, dendrites, and an axon, allowing them to receive, process, and send signals. The brain and spinal cord are made up of neurons but are not the basic working unit. Receptors are sensory organs that detect stimuli but do not transmit signals like neurons do. Therefore, the correct choice is C because neurons are essential for communication within the nervous system.
Question 3 of 5
Therapy that allows residents with AD to believe they live in the past is
Correct Answer: B
Rationale: Validation therapy is the correct answer. It involves validating the feelings and beliefs of individuals with Alzheimer's disease (AD), even if they are not based in reality. This approach helps to reduce stress and anxiety by acknowledging and respecting their emotions. A: Reality orientation focuses on helping individuals with AD understand current time, place, and person, which is opposite to the approach mentioned in the question. C: Reminiscence therapy involves recalling past memories but does not necessarily involve validating false beliefs about living in the past. D: Remotivation therapy aims to increase motivation and engagement, but it is not specifically related to addressing the belief of living in the past.
Question 4 of 5
A tumor that is cancerous is called a(n) ______ tumor.
Correct Answer: C
Rationale: The correct answer is C: Malignant. A malignant tumor is cancerous because it can invade nearby tissues and spread to other parts of the body. This term is used to describe tumors that are harmful and have the potential to be life-threatening. Incorrect choices: A: Opportunistic - This term is not related to tumor classification. Opportunistic refers to infections that occur when the immune system is weakened. B: Benign - Benign tumors are non-cancerous and do not invade nearby tissues or spread to other parts of the body. D: Ballistic - This term is unrelated to tumor classification and refers to the science of projectiles and firearms.
Question 5 of 5
One reason why a resident may not be allowed fluids before surgery is
Correct Answer: B
Rationale: The correct answer is B: Not drinking fluids can help prevent vomiting and aspiration. Before surgery, withholding fluids can reduce the risk of aspiration, where stomach contents enter the lungs during anesthesia induction. Aspiration can lead to serious complications, such as pneumonia. Choices A, C, and D are incorrect because drinking more fluids than usual, incontinence risk, and surgery success rate are not directly related to the preoperative fasting guidelines.
