1. What is the therapeutic use of Alprazolam?
- A. Preventing thrombus formation
- B. Relief of anxiety
- C. Decreasing the risk of stroke
- D. Increasing urinary output
Correct answer: B
Rationale: The therapeutic use of Alprazolam is for the relief of anxiety. Alprazolam belongs to a class of medications known as benzodiazepines, which are commonly prescribed to manage anxiety disorders and panic attacks. It works by enhancing the effects of a natural chemical in the body (GABA) to produce a calming effect on the brain and nerves, thereby alleviating symptoms of anxiety.
2. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following herbal supplements 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 can reduce the effectiveness of Warfarin by interacting with its metabolism pathways, potentially leading to decreased anticoagulant effects. Therefore, clients on Warfarin therapy should avoid St. John's wort. While echinacea, garlic, and ginseng are also herbal supplements that can interact with Warfarin, St. John's wort is particularly known for its significant impact on Warfarin metabolism. Echinacea may increase the risk of bleeding when taken with Warfarin, garlic may potentiate the anticoagulant effects of Warfarin, and ginseng may also increase the risk of bleeding. However, St. John's wort is the most crucial to avoid due to its significant impact on Warfarin metabolism.
3. A healthcare provider is administering a Dopamine infusion at a low dose to a client who has severe heart failure. Which of the following findings is an expected effect of this medication?
- A. Lowered heart rate
- B. Increased myocardial contractility
- C. Decreased conduction through the AV node
- D. Vasoconstriction of renal blood vessels
Correct answer: B
Rationale: Dopamine, when administered at a low dose, acts on beta1 receptors in the heart, leading to increased myocardial contractility. This positive inotropic effect results in improved cardiac output, which is beneficial for a client with severe heart failure. Dopamine does not typically cause lowered heart rate, decreased conduction through the AV node, or vasoconstriction of renal blood vessels at low doses.
4. A client has a new prescription for Levodopa/Carbidopa for Parkinson's disease. Which of the following instructions should the nurse include?
- A. Increase intake of protein-rich foods.
- B. Expect muscle twitching to occur.
- C. Take this medication with food.
- D. Anticipate relief of manifestations in 24 hours.
Correct answer: C
Rationale: The correct instruction for the nurse to include is to advise the client to take Levodopa/Carbidopa with food. This recommendation helps reduce gastrointestinal side effects commonly associated with this medication. Food can help minimize nausea and other stomach-related issues that may occur when taking Levodopa/Carbidopa. Options A, B, and D are incorrect. Increasing intake of protein-rich foods is not necessary with this medication. Muscle twitching is not an expected side effect of Levodopa/Carbidopa. Anticipating relief of manifestations in 24 hours is unrealistic as it may take days to weeks for the full therapeutic effect of the medication to be achieved.
5. When reviewing facility policies for IV therapy with the team, a nurse manager should remind the team that which technique helps minimize the risk of catheter embolism?
- A. Performing hand hygiene before and after IV insertion
- B. Rotating IV sites at least every 72 hours
- C. Minimizing tourniquet time
- D. Avoiding reinserting the needle into an IV catheter
Correct answer: D
Rationale: Avoiding reinserting the needle into an IV catheter is crucial to minimizing the risk of catheter embolism. Reinserting the needle can lead to the severing of the catheter's end, potentially causing a catheter embolism, a serious complication. The other options, while important for IV therapy safety, are not directly related to preventing catheter embolism.
