A client diagnosed with trigeminal neuralgia is experiencing intermittent, sudden, severe pain on the left side of the face. The nurse identifies which classification of medications is most effective in treating this pain.

Choice A reason: The inability to take risks is not a quality of an effective nurse leader, as it may limit the leader's potential for growth, innovation, and improvement. Effective nurse leaders are willing to take calculated risks that are based on evidence, experience, and intuition. They are also able to learn from their mistakes and failures and use them as opportunities for development.

Choice B reason: Never consider being a follower is not a quality of an effective nurse leader, as it may indicate a lack of flexibility, collaboration, and respect for others. Effective nurse leaders are able to adapt to different situations and roles, depending on the needs and goals of the team. They are also able to recognize the strengths and contributions of their followers and empower them to achieve their full potential.

Choice C reason: The ability to set priorities is a quality of an effective nurse leader, as it helps the leader to focus on the most important and urgent tasks and goals. Effective nurse leaders are able to identify the needs and expectations of their clients, staff, and organization, and allocate their time, resources, and energy accordingly. They are also able to delegate tasks appropriately and efficiently.

Choice D reason: Integrity is a quality of an effective nurse leader, as it reflects the leader's honesty, trustworthiness, and ethical standards. Effective nurse leaders are able to act in accordance with their values and principles, and uphold the professional code of conduct. They are also able to communicate openly and transparently, and accept responsibility and accountability for their actions and decisions.

Choice E reason: Critical care certification is not a quality of an effective nurse leader, as it is not a requirement or a guarantee for leadership success. Critical care certification is a credential that demonstrates the nurse's knowledge and competence in providing care to critically ill patients. While it may enhance the nurse's clinical skills and confidence, it does not necessarily reflect the nurse's leadership skills or abilities. Effective nurse leaders can come from various backgrounds and specialties, as long as they have the necessary qualities and attributes that enable them to lead others effectively.

Choice A reason: Repeat dose in 1 hour for unrelieved headache. This instruction is incorrect because sumatriptan should not be taken more than twice in 24 hours. Taking too much sumatriptan can cause serious side effects, such as high blood pressure, stroke, or heart problems.

Choice B reason: Chew the tablet well before swallowing. This instruction is incorrect because sumatriptan tablets should be swallowed whole with water. Chewing the tablet may affect its absorption and effectiveness.

Choice C reason: If you experience chest pain, call your physician immediately. This instruction is correct because chest pain is a serious and potentially life-threatening side effect of sumatriptan. Chest pain may indicate a heart attack or coronary artery spasm, which require immediate medical attention.

Choice D reason: Take daily to prevent headaches. This instruction is incorrect because sumatriptan is not a preventive medication for migraines. It is only used to treat acute migraine attacks when they occur. Taking sumatriptan daily can cause rebound headaches, which are worse and more frequent than the original ones.
