Correct Answer: A

Rationale: An elevated white blood cell count (WBC 15,000/mm�) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.

Correct Answer: C

Rationale: The priority nursing intervention in this scenario is to contact the primary health care provider and discuss the possibility of simplifying the medication regimen. Simplifying the medication regimen is crucial for a client with early Alzheimer's disease to ensure they can manage their medications independently and safely. This intervention focuses on optimizing the client's ability to adhere to the prescribed medication schedule. Choices A and D involve external assistance and may not address the core issue of simplifying the regimen. Choice B, while helpful, does not directly address the need to simplify the regimen to enhance the client's medication management.

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.

Correct Answer: A

Rationale: The correct answer is A. When a healthcare provider witnesses a client signing an informed consent form for surgery, they are affirming that the signature on the form belongs to the client. This is crucial for ensuring patient autonomy and informed decision-making. Choices B, C, and D are incorrect because while it is important for the client to understand the risks of surgery, be aware of postoperative care instructions, and have an opportunity to ask questions, these elements are not specifically affirmed by the healthcare provider witnessing the signature.

Correct Answer: A

Rationale: Correct answer: When removing ticks, it is essential to use blunt tweezers to grasp the tick as close to the head as possible and pull upward with even, steady pressure to remove the entire tick. Option B is incorrect because burning ticks can increase the risk of infection and is not recommended. Option C is incorrect as waiting for ticks to drop off by themselves prolongs potential exposure to tick-borne diseases. Option D is incorrect as miconazole is an antifungal medication and not used for tick removal.
