Pathophysiology Exam 1 Quizlet
1. A patient's antiretroviral therapy has not been as efficacious as her care team had predicted, and maraviroc (Selzentry) has consequently been added to her drug regimen. The nurse should recognize this drug as belonging to what category of antiretroviral?
- A. Fusion protein inhibitors
- B. Protease inhibitors
- C. CCR5 antagonists
- D. Integrase strand transfer inhibitors
Correct answer: C
Rationale: Women with a history of breast cancer should avoid hormone replacement therapy due to the increased risk of cancer recurrence.
2. A nurse is providing discharge teaching to a client who is postoperative following a mastectomy. Which of the following instructions should the nurse include?
- A. Avoid using deodorant until the incision heals.
- B. Perform arm exercises 24 hours after surgery.
- C. Wear tight-fitting clothing to support the incision.
- D. Perform arm exercises 2 days after surgery.
Correct answer: A
Rationale: The correct instruction for the nurse to include is to advise the client to avoid using deodorant until the incision heals. Using deodorant can lead to skin irritation, which should be prevented following a mastectomy. Choice B is incorrect because performing arm exercises should typically be delayed until recommended by the healthcare provider to prevent strain on the surgical site. Choice C is incorrect as tight-fitting clothing can increase discomfort and hinder proper healing. Choice D is also incorrect because initiating arm exercises should be based on the healthcare provider's guidance and not a specific timeframe.
3. Which condition is characterized by the narrowing or blockage of arteries that supply blood to the heart by plaque?
- A. Coronary artery disease (CAD)
- B. Atherosclerosis
- C. Peripheral artery disease
- D. Congestive heart failure
Correct answer: A
Rationale: The correct answer is A, Coronary artery disease (CAD). CAD specifically refers to the condition where the arteries supplying blood to the heart become narrowed or blocked by plaque buildup. Choice B, Atherosclerosis, is a general term for the hardening and narrowing of arteries due to plaque buildup but does not specifically mention the heart. Choice C, Peripheral artery disease, involves narrowing of arteries that supply blood to areas other than the heart. Choice D, Congestive heart failure, is a condition where the heart is unable to pump blood effectively but is not primarily caused by narrowed or blocked arteries.
4. A patient on the oncology unit is receiving carmustine, a chemotherapy agent, and the nurse is aware that a significant side effect of this medication is thrombocytopenia. Which symptom should the nurse assess for in patients at risk for thrombocytopenia?
- A. Interrupted sleep pattern
- B. Hot flashes
- C. Epistaxis (nose bleed)
- D. Increased weight
Correct answer: C
Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which increases the risk of bleeding and hemorrhage. Patients receiving chemotherapy agents like carmustine may experience thrombocytopenia as a significant side effect. Epistaxis (nosebleeds) is a common symptom associated with thrombocytopenia, as the blood vessels can become more fragile, and even minor trauma or spontaneous bleeding can occur. Therefore, assessing for signs of bleeding, including epistaxis, is crucial in patients at risk for thrombocytopenia.
5. A client with a new prescription for levothyroxine is receiving teaching from a nurse. Which statement indicates understanding of the teaching?
- A. I should take this with food
- B. I will see immediate results
- C. I might not realize the full effect of the medication for several weeks
- D. I should stop if I feel better
Correct answer: C
Rationale: The correct answer is C: 'I might not realize the full effect of the medication for several weeks.' Levothyroxine is a medication that may take several weeks for the full effect to be evident. Choice A is incorrect because levothyroxine should be taken on an empty stomach. Choice B is incorrect because immediate results are not expected with levothyroxine. Choice D is incorrect because stopping the medication without consulting a healthcare provider can be harmful, even if the client feels better.
