Correct Answer: D

Rationale: The correct answer is D because brushing off any visible powder on the skin and clothing is the first step in managing exposure to powdered lime. This action helps to remove the source of exposure and prevent further absorption through the skin. It is crucial to prevent additional contact and reduce the risk of further harm. Obtaining vital signs (choice A) and a complete blood count (choice B) can be important but should come after the initial decontamination. Decontaminating the patient by showering with water (choice C) is not recommended for lime exposure as it can react with water and cause further injury.

Correct Answer: A

Rationale: The correct answer is A: Burden versus benefit. In ethical decision-making, considering the burden of treatment on the patient versus the potential benefits is crucial. This involves weighing the risks, benefits, and potential harm of treatment options. Family's wishes (B) and patient's wishes (C) are important factors but may not always align with what is ethically best for the patient. Potential outcomes of treatment options (D) are relevant but do not directly address the ethical dilemma of balancing burden and benefit. Therefore, A is the correct choice as it directly relates to the ethical principles guiding decision-making in this scenario.

Correct Answer: D

Rationale: The correct answer is D: Ask the healthcare provider about tapering the drug dose over the next week. This answer is correct because propranolol is a beta-blocker, and abrupt discontinuation can lead to rebound hypertension, angina, or even myocardial infarction due to the sudden withdrawal of the medication. Tapering the drug dose over time allows the body to adjust gradually and reduces the risk of these adverse effects. Choice A is incorrect because obtaining another antihypertensive prescription is not necessary if the client's blood pressure has been normal for the past three months. Choice B is incorrect because abruptly stopping the medication without tapering can lead to withdrawal symptoms. Choice C is incorrect because simply reporting uncomfortable symptoms without taking appropriate action (tapering the drug dose) is not addressing the potential risks associated with abrupt discontinuation of propranolol.

Correct Answer: B

Rationale: The correct answer is B: Self-directed study of best practice for the patients she cares for. This choice aligns with the Synergy Model by promoting individualized patient care based on best practices. Self-directed study allows the nurse to enhance their knowledge and skills to provide optimal care tailored to each patient's unique needs. Attending mandatory in-service programs (A) may not directly support the individualized care approach. Gathering demographic data (C) is important but not specific to the Synergy Model's focus on patient acuity and nurse competencies. Participating in a research study (D) may contribute to evidence-based practice, but it does not directly relate to the Synergy Model's emphasis on aligning nurse competencies with patient needs.

Correct Answer: C

Rationale: The correct answer is C: Administer the dose as prescribed. Verapamil is a calcium channel blocker used to treat atrial flutter. The vital signs obtained are within normal range for this medication. A heart rate of 92 and blood pressure of 110/76 are not contraindications for administering verapamil. Option A is incorrect as calcium gluconate is not indicated in this situation. Option B is incorrect because the vital signs are stable and do not warrant withholding the medication. Option D is incorrect as there is no need to delay the administration of verapamil based on the vital signs provided.
