1. A patient is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?
- A. Hemoglobin
- B. Prothrombin time (PT)
- C. Bleeding time
- D. Activated partial thromboplastin time (aPTT)
Correct answer: B
Rationale: The correct answer is to monitor Prothrombin time (PT) when a patient is on warfarin therapy. Warfarin affects blood clotting, and PT is used to assess the therapeutic effect of this medication. Hemoglobin (Choice A) is not directly affected by warfarin therapy and does not reflect its therapeutic effect. Bleeding time (Choice C) measures the time it takes for bleeding to stop after a standardized cut and is not specific to warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.
2. A healthcare professional is preparing to administer a transfusion of 300 mL of pooled platelets for a client who has severe Thrombocytopenia. How long should the healthcare professional plan to administer the transfusion over?
- A. Within 30 min/unit
- B. Within 60 min/unit
- C. Within 2 hr/unit
- D. Within 4 hr/unit
Correct answer: A
Rationale: Platelets are fragile components that must be administered quickly to maintain their effectiveness and minimize the risk of clumping. The recommended administration time for platelets is within 15 to 30 minutes per unit. This rapid administration helps ensure the platelets remain viable and functional for the client receiving the transfusion. Therefore, the correct answer is to administer the transfusion within 30 minutes per unit. Choices B, C, and D are incorrect as they exceed the recommended administration time for platelets, which could compromise their efficacy and pose risks to the client.
3. A client with tobacco use disorder is being educated about Nicotine replacement therapy. Which statement by the client indicates an understanding of the teaching?
- A. I should avoid eating right before chewing a piece of nicotine gum.
- B. I will need to stop using the nicotine gum after 1 year.
- C. I know that nicotine gum is a safe alternative to smoking during pregnancy.
- D. I must chew the nicotine gum quickly for about 15 minutes.
Correct answer: A
Rationale: The correct answer is A. To maximize the effectiveness of nicotine gum, the client should avoid eating or drinking 15 minutes before and while using it. This helps ensure proper absorption of nicotine through the oral mucosa. Choice B is incorrect because the duration of nicotine gum use can vary depending on the individual's needs and progress. Choice C is incorrect as nicotine gum should be used during pregnancy only under healthcare provider guidance. Choice D is incorrect because nicotine gum should be chewed slowly until a tingling sensation is felt, then parked between the cheek and gum until the tingling stops.
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 the nurse should include is to take Levodopa/Carbidopa with food. Taking this medication with food helps reduce gastrointestinal side effects. Instructing the client to take the medication with food promotes better tolerance and absorption of the drug. Choice A is incorrect because increasing protein-rich foods is not specifically related to the administration of this medication. Choice B is incorrect as muscle twitching is not a common side effect of Levodopa/Carbidopa. Choice D is incorrect because relief of manifestations may take longer than 24 hours to occur.
5. A client is taking lisinopril. Which of the following outcomes indicates a therapeutic effect of the medication?
- A. Decreased blood pressure
- B. Increase in HDL cholesterol
- C. Prevention of bipolar manic episodes
- D. Improved sexual function
Correct answer: A
Rationale: The therapeutic effect of lisinopril, an ACE inhibitor, is indicated by a decrease in blood pressure. Lisinopril works by relaxing blood vessels, leading to a reduction in blood pressure. Monitoring and achieving a decrease in blood pressure is a key outcome when managing hypertension with lisinopril. Choices B, C, and D are incorrect because lisinopril is not intended to increase HDL cholesterol, prevent bipolar manic episodes, or improve sexual function. Therefore, the correct outcome indicating the therapeutic effect of lisinopril is a decrease in blood pressure.
