Pharmacology for LPN
1. The nurse is assisting with the care of a client who is on a continuous heparin infusion for deep vein thrombosis (DVT). Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Activated partial thromboplastin time (aPTT)
- C. International normalized ratio (INR)
- D. Platelet count
Correct answer: B
Rationale: To evaluate the effectiveness of heparin therapy in a client with DVT, the nurse should monitor the activated partial thromboplastin time (aPTT). The aPTT test helps ensure that the dose of heparin is within the therapeutic range, which is essential for preventing clot formation or excessive bleeding. Monitoring aPTT is crucial in managing patients on heparin therapy to maintain the delicate balance between preventing thrombosis and avoiding hemorrhage. Prothrombin time (PT) and International normalized ratio (INR) are more indicative of warfarin therapy effectiveness, not heparin. Platelet count assesses platelet levels and function, not the effectiveness of heparin therapy for DVT.
2. A nurse is assessing a client diagnosed with schizophrenia. The nurse asks the client to interpret the following statement: “When the cat’s away, the mice will play.” The client responds, “The mice come out when the cat is not around.” The nurse should document this finding as:
- A. Echolalia
- B. Associative looseness
- C. Neologisms
- D. Concrete thinking
Correct answer: D
Rationale: The client’s literal interpretation of the statement is an example of concrete thinking, a cognitive symptom often seen in schizophrenia where abstract thinking is impaired. Choice A, Echolalia, is the repetition of words spoken by others, which is not demonstrated in this scenario. Choice B, Associative looseness, refers to a disturbance in the logical progression of thoughts, leading to a disorganized thought process. Choice C, Neologisms, involves creating new words or phrases with unique meanings, which is not evident in the client's response.
3. A nurse is planning care for a client following gastric bypass surgery. The nurse should include which of the following dietary instructions when preparing the client for discharge?
- A. Start each meal with a protein source.
- B. Consume at least 25g of fiber daily.
- C. Check your blood glucose level before each meal.
- D. Limit your meals to three times per day.
Correct answer: A
Rationale: The correct answer is A: 'Start each meal with a protein source.' Protein is crucial for healing and maintaining muscle mass after gastric bypass surgery, making it essential to include in each meal. Choice B is incorrect because immediately after surgery, the focus is typically on a low-fiber diet to aid in healing. Choice C is unrelated to the nutritional needs following gastric bypass surgery. Choice D is also incorrect as patients recovering from gastric bypass surgery may require more frequent, smaller meals to meet their nutritional needs.
4. You are dispatched to a residence for a 5-year-old child who is not breathing. Upon arrival, you find the child supine on the floor, cyanotic, and unresponsive. You should first:
- A. begin chest compressions.
- B. open the airway and give two rescue breaths.
- C. apply an AED and analyze the rhythm.
- D. ask the parent for the child's medical history.
Correct answer: B
Rationale: When encountering an unresponsive and not breathing child, the initial step is to open the airway and provide two rescue breaths. This action helps to deliver oxygen to the child's lungs and body, which is crucial in attempting to restore breathing and circulation. Chest compressions are not initiated first in pediatric cases unless the child has no signs of circulation after delivering rescue breaths. Applying an AED and analyzing the rhythm is not the initial step in a pediatric cardiac arrest scenario, as the primary focus should be on providing oxygenation. Asking the parent for the child's medical history is not the immediate priority when the child is unresponsive and not breathing, as interventions to support breathing and circulation should be the primary concern.
5. While caring for a client receiving patient-controlled analgesia (PCA), which of the following interventions should the nurse take?
- A. Encourage the client to use the PCA before dressing changes.
- B. Monitor the client's respiratory status.
- C. Provide oxygen therapy to the client as needed.
- D. Ensure the PCA pump is functioning properly.
Correct answer: A
Rationale: Corrected Rationale: The nurse should encourage the client to use the PCA pump before activities like dressing changes, which are likely to cause pain, to ensure effective pain management. Monitoring the client's respiratory status (Choice B) is important but not the priority in this scenario. Providing oxygen therapy (Choice C) is not a routine intervention for all clients on PCA unless specifically indicated. Ensuring the PCA pump is functioning properly (Choice D) is essential, but encouraging the client to use the PCA before painful activities takes precedence to manage pain effectively.
