The practical nurse (PN) is caring for a client whose urine drug screen is positive for cocaine. Which behavior is most likely seen in this client?
Elevated energy level
Powerful craving for more
High self-esteem
Euphoria
The Correct Answer is A
- 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

Correct Answer is D
Explanation
A. Initiate droplet isolation precautions is incorrect because cystic fibrosis is not transmitted by droplets, but by autosomal recessive inheritance.
B. Keep the child on NPO status for 12 hr is incorrect because there is no indication for withholding oral intake in this child. The child needs adequate hydration and nutrition to prevent dehydration and malnutrition due to increased metabolic demands and mucus production.
C. Maintain the child on bed rest for 24 hr is incorrect because bed rest can worsen the child's respiratory status by decreasing lung expansion and increasing mucus retention. The child needs to be encouraged to ambulate and participate in activities as tolerated to promote airway clearance and prevent atelectasis and infection.
D. Administer high-dose antibiotic therapy is correct because the child has signs of a pulmonary infection, such as wheezing, productive cough, and thick sputum. Antibiotics are indicated to treat the infection and prevent complications such as pneumonia and bronchiectasis.
