LPN Pharmacology
1. Prior to a dipyridamole thallium scan, what substance should the LPN/LVN ensure the client has not consumed?
- A. Caffeine
- B. Fatty meal
- C. Excess sugar
- D. Milk products
Correct answer: A
Rationale: Caffeine should be avoided before a dipyridamole thallium scan as it can interfere with the test results. Caffeine is a stimulant that can affect the heart rate and may lead to inaccurate findings during the scan. Fatty meals, excess sugar, and milk products do not specifically interfere with the dipyridamole thallium scan procedure. Therefore, it is essential for the LPN/LVN to check and ensure that the client has not consumed caffeine prior to the procedure to obtain accurate diagnostic results.
2. A client is wearing a continuous cardiac monitor, which begins to alarm at the nurse's station. The nurse sees no electrocardiographic complexes on the screen. What should the nurse do first?
- A. Call a code blue.
- B. Call the healthcare provider.
- C. Check the client's status and lead placement.
- D. Press the recorder button on the ECG console.
Correct answer: C
Rationale: The correct first action for the nurse to take is to check the client's status and lead placement. This step is crucial to ensure that the alarm is not triggered by a simple issue such as lead displacement. Calling a code blue (choice A) is premature without assessing the client first. Contacting the healthcare provider (choice B) can be done after ruling out basic causes for the alarm. Pressing the recorder button (choice D) is not as urgent as checking the client's status and lead placement in this scenario.
3. Which laboratory test should be monitored to evaluate the effectiveness of anticoagulant therapy in a client with deep vein thrombosis (DVT)?
- A. Complete blood count (CBC)
- B. Activated partial thromboplastin time (aPTT)
- C. Serum electrolytes
- D. Liver function tests
Correct answer: B
Rationale: Activated partial thromboplastin time (aPTT) is the laboratory test monitored to evaluate the effectiveness of anticoagulant therapy, particularly with heparin. It measures the time it takes for blood to clot, and monitoring aPTT helps ensure the therapeutic range is maintained to prevent clot formation and excessive bleeding. Choices A, C, and D are incorrect because a complete blood count (CBC) assesses overall health, serum electrolytes evaluate the body's electrolyte balance, and liver function tests assess liver health, none of which directly evaluate the effectiveness of anticoagulant therapy for DVT.
4. A client with known coronary artery disease (CAD) begins to experience chest pain while getting out of bed. What action should the nurse take?
- A. Obtain a prescription for pain medication.
- B. Have the client stop and lie back down in bed.
- C. Report the complaint to the healthcare provider.
- D. Instruct the client to continue getting out of bed and into a chair.
Correct answer: B
Rationale: When a client with CAD experiences chest pain, it indicates myocardial ischemia. The nurse should have the client stop the activity and lie back down in bed to reduce the heart's oxygen demand, decrease myocardial workload, and prevent further ischemia. This action helps in improving blood flow to the heart and can potentially alleviate the chest pain. Option A is incorrect as pain medication should not be the initial action for chest pain in CAD. Option C is incorrect because the nurse should first intervene directly to address the chest pain. Option D is incorrect as continuing the activity can worsen the myocardial ischemia and chest pain.
5. A client is diagnosed with thrombophlebitis. The nurse should tell the client that which prescription is indicated?
- A. Bed rest, with bathroom privileges only
- B. Bed rest, keeping the affected extremity flat
- C. Bed rest, with elevation of the affected extremity
- D. Bed rest, with the affected extremity in a dependent position
Correct answer: C
Rationale: The correct answer is C: Bed rest, with elevation of the affected extremity. Elevating the affected extremity is crucial in managing thrombophlebitis as it helps reduce swelling and promotes venous return. By elevating the affected extremity, the gravitational force assists in venous blood flow back to the heart, thereby reducing the risk of complications associated with thrombophlebitis. Choices A, B, and D are incorrect because they do not address the need for elevation, which is specifically beneficial in the management of thrombophlebitis.
