1. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?
- A. 1/2 tablet.
- B. 1 tablet.
- C. 1 1/2 tablets.
- D. 2 tablets.
Correct answer: C
Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.
2. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
3. A nurse is caring for an older adult client who becomes agitated when the nurse requests the client’s dentures be removed prior to surgery. Which of the following responses should the nurse make?
- A. You seem worried. Are you concerned someone may see you without your teeth?
- B. Don't worry, it’s just for the surgery.
- C. You need to follow the instructions.
- D. The dentures need to be removed for a reason.
Correct answer: D
Rationale: The correct response is to provide a clear rationale for the request, as stated in option D. By explaining the purpose behind removing the dentures, the nurse helps the client understand the necessity, which can reduce agitation and promote cooperation. Option A demonstrates empathy by addressing the client's potential concern about being seen without dentures but lacks a direct explanation. Option B dismisses the client's feelings with a casual statement that may not address the underlying issue. Option C is authoritarian and lacks empathy, potentially escalating the client's agitation.
4. While being prepared for transport to the operating room, a client scheduled for hysterectomy informs the nurse that she no longer wants to have surgery. What action should the nurse take?
- A. Notify the provider about the client's decision
- B. Proceed with the transport
- C. Prepare the surgical site
- D. Document the client’s statement
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to notify the provider about the client's decision. By informing the provider, they can discuss the client's change in decision, explore the reasons behind it, and determine the appropriate course of action. Proceeding with the transport (Choice B) without addressing the client's concerns would not respect the client's autonomy and right to make decisions about their own healthcare. Preparing the surgical site (Choice C) would be premature and inappropriate if the client no longer wishes to proceed with the surgery. While documenting the client's statement (Choice D) is important for documentation purposes, the immediate priority is to involve the provider in the decision-making process.
5. A client with a history of atrial fibrillation is taking digoxin (Lanoxin). Which finding should the healthcare provider be notified of immediately?
- A. Heart rate of 52 beats per minute
- B. Blood pressure of 110/70 mmHg
- C. Blood glucose level of 180 mg/dL
- D. Potassium level of 4.0 mEq/L
Correct answer: A
Rationale: A heart rate of 52 beats per minute is a critical finding in a client taking digoxin, as it may indicate digoxin toxicity. Digoxin can cause bradycardia as a side effect, and a heart rate of 52 bpm warrants immediate attention to prevent adverse outcomes. Monitoring and reporting changes in heart rate are crucial in clients on digoxin therapy to prevent serious complications. The other vital signs and laboratory values provided are within normal ranges or not directly associated with digoxin toxicity in this scenario, making them lower priority for immediate reporting.
