ATI Pathophysiology
1. A patient is being treated for active tuberculosis with ethambutol (Myambutol). The patient states to the nurse that he cannot identify the red and green on the traffic lights when he is driving. Based on this finding, what medical intervention is most appropriate?
- A. Assess for photosensitivity.
- B. Discontinue ethambutol (Myambutol).
- C. Decrease the ethambutol (Myambutol) dose.
- D. Administer vitamin B.
Correct answer: A
Rationale: The correct answer is to assess for photosensitivity. Ethambutol can cause optic neuritis, leading to visual disturbances, including difficulty differentiating red and green colors. This is a sign of optic nerve damage and requires immediate evaluation. Discontinuing ethambutol may be necessary if optic neuritis is confirmed, but this decision should be made by a healthcare provider. Decreasing the dose of ethambutol may not address the visual changes. Administering vitamin B does not directly address the side effect caused by ethambutol.
2. What instruction should the nurse include in this patient's health education regarding chloroquine phosphate (Aralen) for malaria prophylaxis?
- A. “Take your pill on the same day each week.”
- B. “Watch out for any unusual rash on your trunk and arms, but this isn't cause for concern.”
- C. “Remember to take your chloroquine on an empty stomach.”
- D. “We'll provide you with enough syringes and teach you how to inject the drug.”
Correct answer: A
Rationale: The correct instruction for the nurse to include in this patient's health education regarding chloroquine phosphate (Aralen) for malaria prophylaxis is to “Take your pill on the same day each week.” This is essential because chloroquine is typically taken once a week on the same day to ensure consistent protection against malaria. Choice B is incorrect because while rashes are a possible side effect of chloroquine, they are not a usual occurrence and should be reported to the healthcare provider. Choice C is incorrect because chloroquine does not need to be taken on an empty stomach. Choice D is incorrect as chloroquine is typically administered orally, not by injection.
3. A patient is prescribed raloxifene (Evista) for osteoporosis. What is the primary mechanism of action for this medication?
- A. Raloxifene decreases bone resorption, which helps to maintain or increase bone density.
- B. Raloxifene increases calcium absorption in the intestines, which helps build stronger bones.
- C. Raloxifene stimulates new bone formation by increasing osteoblast activity.
- D. Raloxifene decreases calcium excretion by the kidneys, helping to maintain bone density.
Correct answer: A
Rationale: Raloxifene decreases bone resorption, which helps to maintain or increase bone density, making it effective in the prevention and treatment of osteoporosis.
4. When communicating with a client who has cognitive impairment, which of the following will Nurse Dory use?
- A. Complete explanations with multiple details
- B. Pictures or gestures instead of words
- C. Stimulating words and phrases to capture the client’s attention
- D. Short words and simple sentences
Correct answer: D
Rationale: Nurse Dory will use short words and simple sentences when communicating with a client who has cognitive impairment. This approach is effective because it helps improve understanding and comprehension for individuals with cognitive challenges. Choice A is incorrect because complete explanations with multiple details may overwhelm or confuse clients with cognitive impairment. Choice B is not the most effective option as using pictures or gestures instead of words may not always be practical or necessary. Choice C is also not ideal as stimulating words and phrases may cause distraction rather than enhance communication for clients with cognitive impairment.
5. A woman with severe visual and auditory deficits is able to identify individuals by running her fingers lightly over her face. Which source is most likely to provide the input that allows for the woman's unique ability?
- A. Special somatic afferent fibers
- B. General somatic afferents
- C. Special visceral afferent cells
- D. General visceral afferent neurons
Correct answer: C
Rationale: The correct answer is C, special visceral afferent cells. These cells are responsible for functions like taste and smell. In individuals with severe visual and auditory deficits, their other sensory abilities, such as touch, can be heightened. Special somatic afferent fibers (choice A) are involved in sensations like touch and vibration from the skin and muscles, but they are not specific to the face. General somatic afferents (choice B) transmit sensory information from the skin, muscles, and joints, but they are not specialized for the unique ability described. General visceral afferent neurons (choice D) are responsible for transmitting sensory information from internal organs, not relevant to the woman's ability to identify individuals through touch on her face.
