Correct Answer: C

Rationale: Vomiting bile is not typically a sign of internal bleeding but is more commonly associated with issues in the gastrointestinal tract. Signs of internal bleeding include painful or swollen extremities, a tender, rigid abdomen, and bruising. Painful or swollen extremities can indicate bleeding from an extremity injury, a tender, rigid abdomen can signal abdominal bleeding, and bruising can result from blood vessel damage. Therefore, the correct answer is 'C: vomiting bile,' as it is not a typical sign of internal bleeding.

Correct Answer: B

Rationale: Mammography is specifically used to detect tumors or abnormal growths, especially in breast tissue. It is not a tool for identifying pain, edema, or epilepsy. Therefore, the correct answer is 'tumor.' Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder; none of these are conditions typically detected through mammography.

Correct Answer: C

Rationale: Client and family communication and education concerning restraints are essential to encourage cooperation. When the client and family understand the purpose and expected benefits of restraints, they are more likely to cooperate. This understanding can help prevent well-meaning family members from releasing restraints due to confusion or lack of information. Therefore, choice C is correct. Choices A, B, and D are incorrect because confusing both groups further, helping with coping and stress levels, and shifting responsibility to the client and family are not the primary goals of communication and education concerning restraints.

Correct Answer: B

Rationale: A nursing advocate does not make decisions for others but instead empowers individuals to make decisions for themselves. By encouraging individuals to make their own decisions and supporting them in this process, nursing advocates uphold the principle of self-determination. This approach respects the autonomy and independence of individuals in managing their care. Therefore, the correct answer is to 'encourage persons to make decisions for themselves and act with or on behalf of the person to support those decisions.' Choices A, C, and D are incorrect as they do not align with the role of a nursing advocate in promoting patient autonomy and self-determination.

Correct Answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.
