Correct Answer: B

Rationale: Lidocaine is used to treat ventricular tachycardia. This medication slowly exerts an antiarrhythmic effect by increasing the electrical stimulation threshold of the ventricles without depressing the force of ventricular contractions. It is not used for atrial arrhythmias; thus, answer A is incorrect. Answers C and D are incorrect because lidocaine does not slow the heart rate, so it is not used for heart block or bradycardia.

Correct Answer: B

Rationale: Male children are sexually abused nearly as often as female children. Perpetrators are usually men but can be women. Needs of male children who have been sexually abused might be different from the needs of female survivors. Male survivors might respond in anger, question their sexuality, use alcohol and other drugs, and might try to prove their masculinity by performing daring acts. Choice A is incorrect because male victims of sexual abuse can indeed have long-term psychological problems. Choice C is incorrect as not all male sex abuse survivors grow up to abuse other children. Choice D is incorrect as the needs of sexually abused children can vary based on gender and individual circumstances.

Correct Answer: A

Rationale: Drug tolerance is characterized by the ability to ingest a larger dose without adverse effects and decreased sensitivity to the substance. In this scenario, the client needing an increased dose of hydrocodone to achieve the same pain relief indicates tolerance developing, not addiction. Choice B is incorrect as it describes drug dependence, where the individual is preoccupied with the drug and has a loss of control. Choice C is incorrect because addiction involves psychological behaviors related to substance use, not just physical dependence with withdrawal symptoms and tolerance. Choice D is incorrect as it refers to a dual diagnosis, which is the coexistence of substance abuse and psychiatric disorders, not the development of tolerance to a drug.

Correct Answer: B

Rationale: Maintaining a sense of self is crucial for clients in healthcare settings. Treating the client with dignity is a fundamental nursing principle that helps preserve the client's self-worth and identity. Addressing the client by their first name when interacting with them is a way to show respect, but it alone may not significantly contribute to maintaining their sense of self. Explaining procedures to the client, regardless of their attentiveness, is essential for informed consent and autonomy, empowering them in their care. Encouraging the use of personal items can foster a sense of identity as these items often hold personal significance and emotional value for the client, thus supporting their sense of self; therefore, discouraging their use would be counterproductive in maintaining a client's sense of self.
