1. In reviewing a client's health record, which condition would be a contraindication for using Propranolol to treat hypertension?
- A. Asthma
- B. Glaucoma
- C. Hypertension
- D. Tachycardia
Correct answer: A
Rationale: Propranolol is a nonselective beta-adrenergic blocker that blocks both beta1 and beta2 receptors. Blocking beta2 receptors in the lungs can lead to bronchoconstriction, making it unsuitable for clients with asthma. Therefore, asthma is a contraindication for taking Propranolol. Glaucoma, hypertension, and tachycardia are not contraindications for using Propranolol to treat hypertension.
2. When teaching a client with a new prescription for Clopidogrel, which laboratory value should the nurse monitor to assess for potential adverse effects?
- A. White blood cell count
- B. Platelet count
- C. Hemoglobin
- D. Blood glucose
Correct answer: B
Rationale: Clopidogrel is an antiplatelet medication that works by reducing the formation of blood clots. Therefore, the nurse should monitor the client's platelet count to assess for potential bleeding complications. A decrease in platelet count could indicate a risk of bleeding, which is an adverse effect associated with Clopidogrel therapy. Monitoring other laboratory values like white blood cell count, hemoglobin, and blood glucose is important for assessing overall health status but is not directly related to the potential adverse effects of Clopidogrel.
3. When providing discharge instructions to a client prescribed Warfarin, which herbal supplement should the nurse instruct the client to avoid?
- A. St. John's wort
- B. Echinacea
- C. Garlic
- D. Ginseng
Correct answer: A
Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by interacting with its metabolism. While garlic and ginseng are also known to interact with Warfarin, the specific supplement the nurse should instruct the client to avoid in this scenario is St. John's wort. Echinacea, although an herbal supplement, is not typically associated with significant interactions with Warfarin and is not the primary concern in this case.
4. A client has a new prescription for methotrexate to treat Rheumatoid Arthritis. The nurse should expect to monitor the client for which of the following adverse effects?
- A. Insomnia
- B. Hypertension
- C. Bone marrow suppression
- D. Constipation
Correct answer: C
Rationale: The correct answer is bone marrow suppression (Choice C). Methotrexate can lead to bone marrow suppression, resulting in adverse effects such as anemia, leukopenia, and thrombocytopenia. Monitoring for signs of decreased blood cell counts is essential to prevent complications and adjust treatment as needed. Choices A, B, and D are incorrect. Insomnia, hypertension, and constipation are not typically associated with methotrexate use in the treatment of Rheumatoid Arthritis.
5. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?
- A. Four medications decrease the risk of a severe allergic reaction.
- B. Four medications reduce the chance that the bacteria will become resistant.
- C. Four medications reduce the risk of adverse reactions.
- D. Four medications decrease the chance of having a positive tuberculin skin test.
Correct answer: B
Rationale: The correct answer is B. When treating tuberculosis, using a combination of medications is crucial to reduce the risk of bacteria developing resistance to any single drug. This approach helps prevent treatment failure and ensures successful treatment outcomes. Choice A is incorrect because the primary purpose of using multiple medications is not related to allergic reactions. Choice C is incorrect as the risk reduction is mainly focused on bacterial resistance rather than adverse reactions. Choice D is not relevant as the purpose of taking multiple medications is not to affect the tuberculin skin test results.
