1. What action should be implemented to prevent the formation of a sacral ulcer for an immobile client?
- A. Maintain the client in a lateral position using protective wrist and vest restraints.
- B. Position the client prone with a small pillow below the diaphragm.
- C. Raise the head and knee gatch when lying in a supine position.
- D. Transfer the client to a wheelchair close to the nursing station for observation.
Correct answer: B
Rationale: Positioning the client prone with a small pillow below the diaphragm helps maintain proper alignment and provides optimal pressure relief over the sacral area, reducing the risk of developing a pressure ulcer. This position redistributes pressure away from bony prominences, such as the sacrum, which is crucial in preventing ulcer formation in immobile clients. Choice A is incorrect because using restraints can lead to further complications and does not address pressure relief. Choice C is incorrect as raising the head and knee gatch in a supine position does not directly alleviate pressure over the sacrum. Choice D is incorrect as transferring to a wheelchair does not address pressure relief or optimal positioning to prevent sacral ulcers.
2. A client with trigeminal neuralgia tells the nurse that acetaminophen (Tylenol) is taken on a frequent daily basis for relief of generalized discomfort. The nurse reviews the client's laboratory results and determines that which of the following indicates toxicity associated with the medication?
- A. Sodium of 140 mEq/L
- B. Prothrombin time of 12 seconds
- C. Platelet count of 400,000 cells/mm³
- D. A direct bilirubin level of 2 mg/dL
Correct answer: D
Rationale: A direct bilirubin level of 2 mg/dL indicates liver damage, which can be caused by an overdose of acetaminophen. Acetaminophen toxicity can lead to liver injury, manifesting as elevated bilirubin levels and other liver function test abnormalities.
3. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?
- A. 75ml/hr
- B. 100ml/hr
- C. 50ml/hr
- D. 25ml/hr
Correct answer: A
Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.
4. The healthcare professional is preparing to administer a blood transfusion to a client with anemia. Which action is most important to prevent a transfusion reaction?
- A. Check the client's vital signs before starting the transfusion.
- B. Use a blood filter when administering the transfusion.
- C. Verify the blood type and Rh factor with another healthcare professional.
- D. Administer antihistamines before starting the transfusion.
Correct answer: C
Rationale: Verifying the blood type and Rh factor with another healthcare professional is the most crucial action to prevent a transfusion reaction. Ensuring compatibility between the donor blood and the recipient is essential in preventing adverse reactions such as hemolytic transfusion reactions. Checking vital signs is important for monitoring the client during the transfusion process but does not directly prevent a transfusion reaction. Using a blood filter can help remove clots and debris but does not address the risk of a reaction due to blood type incompatibility. Administering antihistamines before the transfusion is not a standard practice to prevent transfusion reactions related to blood type incompatibility.
5. During a home visit, the nurse finds that an elderly client has multiple expired medications. What should the nurse do first?
- A. instruct the client to dispose of the expired medications
- B. review the client's current medication regimen
- C. contact the client's healthcare provider
- D. educate the client on the dangers of taking expired medications
Correct answer: B
Rationale: The correct first action for the nurse to take when finding multiple expired medications in an elderly client's home is to review the client's current medication regimen. This step is crucial to identify any potential issues, ensure the client is taking the correct medications, and understand why the expired medications were not used. Instructing the client to dispose of the expired medications (Choice A) can come after understanding the current medication situation. Contacting the client's healthcare provider (Choice C) may be necessary but reviewing the medication regimen should be the initial step. Educating the client on the dangers of taking expired medications (Choice D) is important but should be done after addressing the immediate concern of reviewing the current medications.
