Pathophysiology Exam 1 Quizlet
1. A patient with a history of osteoporosis is prescribed alendronate (Fosamax). What specific instructions should the nurse provide to ensure the effectiveness of the medication?
- A. Take the medication with a full glass of water and remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption.
- B. Take the medication with milk to enhance calcium absorption.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with food to prevent nausea.
Correct answer: A
Rationale: The correct answer is A. Alendronate should be taken with a full glass of water, and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. This positioning helps reduce the risk of esophageal irritation and ensures adequate drug absorption. Choice B is incorrect because alendronate should be taken with water, not milk. Choice C is incorrect as there is no specific advantage to taking alendronate at bedtime. Choice D is incorrect because taking alendronate with food may interfere with its absorption.
2. Mrs. Jordan is an elderly client diagnosed with Alzheimer’s disease. She becomes agitated and combative when a nurse approaches to help with morning care. The most appropriate nursing intervention in this situation would be to:
- A. tell the client firmly that it is time to get dressed.
- B. obtain assistance to restrain the client for safety.
- C. remain calm and talk quietly to the client.
- D. call the doctor and request an order for sedation.
Correct answer: C
Rationale: When dealing with an elderly client with Alzheimer’s disease who is agitated and combative, the most appropriate nursing intervention is to remain calm and talk quietly to the client. This approach can help soothe the client and prevent escalating the situation. Choice A is incorrect as being firm may further agitate the client. Choice B is inappropriate as restraining should only be used as a last resort for safety reasons and after other de-escalation techniques have been attempted. Choice D is not the best initial intervention and should only be considered after other non-pharmacological interventions have failed.
3. The nurse knows which phenomenon listed below is an accurate statement about axonal transport?
- A. Anterograde and retrograde axonal transport allow for the communication of nerve impulses between a neuron and the central nervous system (CNS).
- B. Materials can be transported to the nerve terminal by either fast or slow components.
- C. The unidirectional nature of the axonal transport system protects the CNS against potential pathogens.
- D. Axonal transport facilitates the movement of electrical impulses but precludes the transport of molecular materials.
Correct answer: B
Rationale: The correct answer is B. Axonal transport involves the movement of materials to the nerve terminal by either fast or slow components, which is essential for cell survival. Choice A is incorrect because while anterograde and retrograde axonal transport are involved in the movement of materials, they do not specifically relate to the communication of nerve impulses between a neuron and the CNS. Choice C is incorrect because the unidirectional nature of axonal transport does not primarily function to protect the CNS against pathogens. Choice D is incorrect as axonal transport is responsible for the movement of various materials, not just electrical impulses.
4. Following a spinal cord injury suffered in a motor vehicle accident, a 22-year-old male has lost fine motor function of his finger and thumb, but is still able to perform gross motor movements of his hand and arm. Which component of his 'white matter' has most likely been damaged?
- A. The inner layer (archilayer)
- B. The middle layer (paleolayer)
- C. The outer layer (neolayer)
- D. The reticular formation
Correct answer: C
Rationale: The correct answer is C: The outer layer (neolayer). The white matter of the spinal cord consists of three layers: the outer layer (neolayer), the middle layer (paleolayer), and the inner layer (archilayer). Damage to the outer layer (neolayer) is likely to affect fine motor skills, explaining the loss of fine motor function in the finger and thumb while gross motor movements remain intact. Choices A, B, and D are incorrect as they do not correspond to the specific layer of the white matter that is typically associated with fine motor control.
5. What is a characteristic of coronary artery disease (CAD)?
- A. The build-up of infectious by-products in the lymph nodes
- B. Insufficient delivery of oxygenated blood to the myocardium
- C. Insufficient delivery of carbon dioxide to the lungs
- D. The build-up of bile in the stomach and gallbladder
Correct answer: B
Rationale: The correct characteristic of coronary artery disease (CAD) is the insufficient delivery of oxygenated blood to the myocardium. CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle. This lack of oxygenated blood can result in chest pain, known as angina, and if a coronary artery becomes completely blocked, it can cause a heart attack. Choices A, C, and D are incorrect. Choice A refers to an issue related to the lymphatic system, choice C is about gas exchange in the lungs, and choice D describes a problem with bile accumulation in the digestive system, none of which are characteristics of CAD.
