1. A healthcare provider is reviewing the health care record of a client who is asking about conjugated equine estrogens. The provider should inform the client this medication is contraindicated in which of the following conditions?
- A. Atrophic vaginitis
- B. Dysfunctional uterine bleeding
- C. Osteoporosis
- D. Thrombophlebitis
Correct answer: D
Rationale: Conjugated equine estrogens are contraindicated in clients with a history of thrombophlebitis due to the increased risk of thrombotic events associated with estrogen use. Thrombophlebitis is characterized by inflammation of a vein with the formation of a clot, and estrogen can further exacerbate this condition, leading to serious complications. Choices A, B, and C are not contraindications for conjugated equine estrogens. Atrophic vaginitis and osteoporosis are conditions where estrogen therapy may actually be indicated. Dysfunctional uterine bleeding is another condition where estrogen therapy can be used to help regulate menstrual bleeding.
2. A client with peptic ulcer disease is prescribed omeprazole. Which finding should indicate to the nurse that the medication is effective?
- A. Relief of headache
- B. Relief of nausea
- C. Relief of abdominal pain
- D. Relief of heartburn
Correct answer: C
Rationale: Relief of abdominal pain is a key indicator of omeprazole effectively treating peptic ulcer disease. Omeprazole works by reducing stomach acid production, which helps alleviate abdominal pain associated with peptic ulcers. While relief of other symptoms like headache, nausea, and heartburn may also occur, the primary therapeutic goal of omeprazole in peptic ulcer disease is to reduce abdominal pain caused by gastric irritation. Therefore, the relief of abdominal pain is the most significant finding to indicate the effectiveness of omeprazole in this context. Choices A, B, and D may improve as a result of decreased stomach acid production, but they are not as specific or central to the therapeutic goal of treating peptic ulcer disease as the relief of abdominal pain.
3. A client is receiving heparin therapy. Which laboratory value should be monitored by the nurse to evaluate the effectiveness of the therapy?
- A. PT
- B. aPTT
- C. INR
- D. Platelet count
Correct answer: B
Rationale: The activated partial thromboplastin time (aPTT) is specifically used to monitor the effectiveness of heparin therapy. It should be maintained at 1.5 to 2 times the normal level. Monitoring aPTT helps ensure that the therapeutic range of heparin is achieved to prevent clot formation while minimizing the risk of bleeding complications. Choice A (PT) is incorrect as it is used to monitor warfarin therapy, not heparin. Choice C (INR) is also incorrect as it is primarily used to monitor warfarin therapy. Choice D (Platelet count) is not directly related to monitoring the effectiveness of heparin therapy.
4. A client has a new prescription for Etravirine, an NNRTI. Which of the following statements should the nurse include in teaching the client?
- A. Take this medication with food.
- B. Take this medication on an empty stomach.
- C. Take this medication at the same time every day.
- D. Take this medication at bedtime to prevent drowsiness.
Correct answer: C
Rationale: The correct statement the nurse should include in teaching the client is to take Etravirine at the same time every day. This ensures consistent blood levels and effectiveness of the medication. Consistent timing is essential to achieve optimal therapeutic effects and avoid missing doses. Choices A and B are incorrect because Etravirine should not necessarily be taken with or without food; it is more important to take it consistently. Choice D is incorrect as there is no need to take Etravirine at bedtime to prevent drowsiness.
5. How do ACE inhibitors work?
- A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
- B. Block stimulation of beta 1 and beta 2 at the receptor sites
- C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
- D. None of the above
Correct answer: C
Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
