A male preoperative client who has already signed the informed consent for a surgical procedure confides to the practical nurse (PN) that he is really frightened and unsure about undergoing the surgery. Which priority action should the PN take?

Choice A reason: Administering corticosteroids is not an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a medication that reduces inflammation and relieves acute exacerbations of multiple sclerosis, but does not affect the client's physical function or mobility.

Choice B reason: Turning and repositioning every 2 hours is not an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a nursing intervention that prevents pressure ulcers and promotes skin integrity, but does not enhance the client's circulation or muscle activity.

Choice C reason: Administering interferon is not an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a medication that modifies the immune system and delays the progression of multiple sclerosis, but does not improve the client's physical function or mobility.

Choice D reason: Encouraging range-of-motion exercises is an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a physical activity that improves the client's blood flow, flexibility, and muscle tone, as well as prevents contractures and spasticity.

Choice A reason: Developing a survey on teen pregnancies is not an appropriate action by the nurse because it does not address the issue of influenza A outbreak in the school, which can affect students of any age or gender.

Choice B reason: Holding a focus group to discuss immunizations is an appropriate action by the nurse because it can educate and inform parents and students about the benefits and risks of influenza vaccination, as well as encourage them to get vaccinated before or during flu season.

Choice C reason: Running a mandatory flu clinic is not an appropriate action by the nurse because it can violate the rights and autonomy of parents and students who may have medical or personal reasons for refusing influenza vaccination, as well as create resentment and resistance among them.

Choice D reason: Closing the school for 6 weeks is not an appropriate action by the nurse because it can disrupt the education and socialization of students, as well as cause economic and logistic problems for parents and teachers. The recommended duration of school closure for influenza A outbreak is 5 to 7 days, which is the typical incubation period of the virus.
