A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?

• Cocaine is a powerfully addictive stimulant drug that increases the levels of dopamine in the brain, which is a chemical messenger related to movement, pleasure, and motivation.
• Cocaine's effects appear almost immediately and last for a few minutes to an hour, depending on the method of use. Some of the short-term effects of cocaine include extreme happiness and energy, mental alertness, hypersensitivity to sight, sound, and touch, and irritability.
• An elevated energy level is one of the most common and noticeable effects of cocaine use, as cocaine stimulates the central nervous system and makes the user feel more alert, active, and confident¹². This effect may also lead to increased physical activity, talkativeness, or aggression.

Therefore, option A is the correct answer, while options B, C, and D are incorrect.

Option B is incorrect because a powerful craving for more cocaine is not a behavior that can be observed by others, but rather an internal feeling that the user may experience due to the addictive nature of the drug.

Option C is incorrect because high self-esteem is not a typical effect of cocaine use, as cocaine may cause paranoia or anxiety in some users.

Option D is incorrect because euphoria is not a behavior that can be observed by others, but rather an emotional state that the user may feel due to the increased dopamine levels in the brain

A. Evaluate the changes the partner requests: This is incorrect because it is not the first action to take. The charge nurse should first listen to and acknowledge the partner's complaints before evaluating any changes or solutions.

B. Review the client's plan of care: This is incorrect because it is not the first action to take. The charge nurse should first understand what aspects of care are unsatisfactory for the partner and why they feel that way.

C. Analyze other reports of poor care to look for trends: This is incorrect because it is not relevant to this situation. The charge nurse should focus on addressing this specific case of dissatisfaction rather than looking for general patterns or issues.

D. Ask the partner to list specific concerns: This is correct because it shows respect and empathy for the partner and allows for clarification and communication of their expectations and needs. It also helps identify any gaps or misunderstandings in the client's care and facilitates problem-solving and resolution.
