A client is drawing up and mixing insulin under the observation of a nurse. Which of the following findings should the nurse identify as an indication that psychomotor learning has taken place?

Correct Answer: B

Rationale: The correct answer is B because the ability to demonstrate the appropriate technique shows that the client has acquired the psychomotor skills needed for insulin preparation. Merely discussing, stating an understanding, or writing the steps does not confirm that the client can physically perform the task correctly. Being able to demonstrate indicates practical application and mastery of the skill. Choice A is incorrect because discussing the technique does not necessarily mean the client can physically perform it. Choice C is incorrect as stating an understanding does not guarantee the client's ability to perform the task. Choice D is incorrect because writing the steps does not assess the client's physical execution of the technique.

Correct Answer: B

Rationale: The correct answer is autonomy. Autonomy is the ethical principle that upholds an individual's right to make decisions about their healthcare, including the choice to refuse treatment or surgery. In this scenario, the client's decision not to have surgery despite the recommendation is an exercise of autonomy. Choice A, fidelity, refers to being faithful and keeping promises, which is not applicable in this situation. Choice C, justice, pertains to fair and equal distribution of resources and treatment, not the individual's right to make decisions. Choice D, nonmaleficence, relates to the obligation to do no harm, which is not directly applicable to the client's decision to refuse surgery.

Correct Answer: D

Rationale: The correct answer is D, Occupational therapist. Occupational therapists specialize in assisting clients with adaptive devices to enhance their ability to perform daily activities like self-feeding. They evaluate client needs and provide interventions to promote independence in activities of daily living. Choice A, Social worker, focuses on psychosocial support and community resources, not directly addressing the physical aspect of self-feeding difficulty. Choice B, Certified nursing assistant, is involved in direct patient care but lacks specialized training in adaptive devices. Choice C, Registered dietitian, primarily focuses on nutrition-related issues and may not have the expertise in adaptive devices and functional rehabilitation necessary for this client's self-feeding challenges.

Correct Answer: A

Rationale: The correct location to auscultate the aortic valve is the second intercostal space to the right of the sternum. This area corresponds to the aortic valve area where aortic valve sounds are best heard. Choices B, C, and D are incorrect for auscultating the aortic valve. The fifth intercostal space to the left of the sternum is where the mitral valve is best heard, the third intercostal space to the left of the sternum is where the pulmonic valve is best heard, and the fourth intercostal space at the midclavicular line is where the tricuspid valve is best auscultated.

Correct Answer: A

Rationale: The correct technique for transferring a client from a bed to a chair to avoid back injuries is to bend at the knees while maintaining a wide stance and a straight back. This position ensures that the nurse uses leg muscles rather than the back muscles for lifting, reducing the risk of injury. Placing the client's hands on the nurse's shoulders and the nurse's hands under the client's axillae provides additional support and stability during the transfer. Using a mechanical lift may be appropriate for certain situations but is not necessary for a simple bed-to-chair transfer. Twisting at the waist while holding the client can lead to back strain or injury. Asking for assistance from another staff member is a good practice, but proper body mechanics should still be followed to ensure safe client handling.
