Correct Answer: B

Rationale: The correct way to take buccal medications is to insert the tablet between the cheek and gums where it will dissolve slowly. Option A is incorrect because buccal medications are not meant to be dissolved in water. Option C is incorrect as sublingual medications are placed under the tongue. Option D is incorrect because chewing a buccal tablet is not the correct administration method.

Correct Answer: A

Rationale: The correct answer is A. Using the planning step of the nursing process to prioritize client care delivery is crucial for effective time management. By prioritizing tasks based on client needs and acuity levels, the nurse can ensure that the most critical care is provided in a timely manner. Choice B is incorrect because while delegation is important, not all tasks can be delegated, and the nurse is ultimately responsible for the care provided. Choice C is incorrect as completing tasks in the order they are assigned may not align with the urgency of client needs. Choice D is incorrect as using a checklist can help the nurse stay organized and ensure that all necessary tasks are completed.

Correct Answer: A

Rationale: Monitoring the white blood cell count is crucial when a patient is undergoing chemotherapy for breast cancer. Chemotherapy can lead to neutropenia, a condition of low white blood cell count, which significantly increases the risk of infections. Monitoring white blood cell count helps healthcare providers intervene promptly to prevent severe infections. Hemoglobin level, while important in assessing oxygen-carrying capacity, is not the priority in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer.

Correct Answer: A

Rationale: The correct first action for the nurse to take in this situation is to check the IV tubing for obstruction. By doing this, the nurse can assess if there is any blockage or kink in the tubing that is impeding the flow of the IV solution. This step is crucial as it helps in identifying the reason for the inadequate infusion rate. Increasing the infusion rate (Choice B) without first checking for obstructions can lead to potential complications if there is a blockage. Administering a bolus of fluid (Choice C) may not be appropriate without addressing the cause of the decreased infusion rate. Similarly, replacing the IV catheter (Choice D) is not the initial priority unless obstruction is ruled out and other troubleshooting measures have been taken.

Correct Answer: B

Rationale: To calculate the number of tablets needed, convert the prescribed dose of Seconal from grams to grains. Since 1 gram is equal to approximately 15.43 grains, 0.1 gram is roughly 1.543 grains. Given that each tablet contains 1.5 grains, administering 1 tablet (which is slightly more than the 1.543 grains needed) provides the correct dose of Seconal. Therefore, the LPN/LVN should plan to administer 1 tablet. Choice A (0.5 tablet) is incorrect as it would provide less than the required dose. Choice C (1.5 tablets) and Choice D (2 tablets) are incorrect as they would exceed the necessary dosage.
