Correct Answer: B

Rationale: When formulating a nursing diagnosis, the nurse should focus on identifying the client's specific health problems that can be addressed through nursing interventions. The correct answer emphasizes the nurse's role in identifying and addressing client-specific issues through nursing care. Choice A is incorrect because nursing diagnoses are distinct from medical diagnoses made by physicians. Choice C is incorrect as it focuses on physician orders rather than the nurse's role in diagnosing and addressing client problems. Choice D is incorrect because it pertains to identifying underlying diseases, which is not the primary focus of nursing diagnoses.

Correct Answer: A

Rationale: The correct answer is A: Psychological abuse. This behavior is classified as psychological abuse, which harms another person through words or threats. The nursing assistant's actions of yelling, making threats, and using food as a form of control fall under psychological abuse. Abandonment (choice B) refers to deserting or leaving a client without care, which is not the case in the scenario. Material exploitation (choice C) involves taking advantage of a person's assets or resources for personal gain, which is not evident here. Physical abuse (choice D) involves causing physical harm, which is not the primary issue in this situation. Therefore, the most appropriate classification for the behavior described in the scenario is psychological abuse.

Correct Answer: B

Rationale: When a client voluntarily participates in a research study and later decides to withdraw, they have the right to be released from the study without any liability. It is unethical to force a participant to continue in a study against their will as this violates their autonomy and personal rights. Choice A is incorrect as it suggests that the client must reimburse the researchers for charges incurred, which is not typically the case unless agreed upon beforehand. Choice C is incorrect as there is no standard practice prohibiting a participant from future studies just because they withdrew from a current one. Choice D is incorrect because participants always have the right to withdraw from a research study at any time.

Correct Answer: A

Rationale: Beneficence is the ethical principle of doing good and acting in the best interest of the client. Providing pain relief to a client in the recovery room who is experiencing pain aligns with beneficence as it promotes the client's well-being and comfort. Choice B is related to autonomy, where the client's wishes regarding treatment are respected. Choice C involves confidentiality and the client's right to privacy. Choice D represents nonmaleficence, as withholding pain medication from a client in pain could cause harm and goes against the principle of doing no harm.

Correct Answer: A

Rationale: The correct answer is 'Unequal leg length.' Shortening of a leg is a common sign of developmental dysplasia of the hip. Limited adduction (Choice B) may be present but is less specific to developmental dysplasia of the hip. Diminished femoral pulses (Choice C) are not typically associated with developmental dysplasia of the hip. Symmetrical gluteal folds (Choice D) are a normal finding and would not be expected in a patient with developmental dysplasia of the hip.
