For each discharge instruction, specify if each action is recommended or contraindicated for the client.

• 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

An antibiotic that can cause nephrotoxicity is an antibiotic that can damage the kidneys, which are the organs that filter the blood and remove waste products and excess fluid from the body. Some examples of nephrotoxic antibiotics are aminoglycosides, vancomycin, amphotericin B, and sulfonamides.

Serum creatinine is a laboratory value that measures the amount of creatinine in the blood. Creatinine is a waste product that is produced by the breakdown of muscle tissue and is normally excreted by the kidneys. A high serum creatinine level indicates that the kidneys are not functioning properly and are unable to filter out the creatinine from the blood.

Before administering an antibiotic that can cause nephrotoxicity, it is important for the practical nurse (PN) to review the serum creatinine level of the client, as it reflects the kidney function and the risk of nephrotoxicity. A normal serum creatinine level ranges from 0.6 to 1.2 mg/dL for men and 0.5 to 1.1 mg/dL for women. If the serum creatinine level is elevated, it may indicate that the client has impaired kidney function or is developing nephrotoxicity from the antibiotic. In this case, the PN should notify the primary healthcare provider and monitor the client for signs and symptoms of nephrotoxicity, such as decreased urine output, edema, hypertension, or electrolyte imbalances .
