Nokea
The practical nurse is caring for a client whose urine drug screen is positive for cocaine. Which behavior is this client likely to exhibit during cocaine withdrawal?
- A. Elevated energy level
- B. Euphoria
- C. High self-esteem
- D. Powerful craving for more
Correct Answer: D
Rationale: The correct answer is D: Powerful craving for more. During cocaine withdrawal, individuals often experience intense cravings for the drug, along with symptoms such as fatigue, depression, and anxiety. These cravings can be overpowering and lead to a strong desire to seek out more cocaine to alleviate the withdrawal symptoms. Choices A, B, and C are incorrect as elevated energy level, euphoria, and high self-esteem are more associated with the effects of cocaine rather than withdrawal symptoms. Withdrawal from cocaine is characterized by the opposite, such as fatigue, low mood, and intense cravings.

A client on bedrest refuses to wear the prescribed pneumatic compression devices after surgery. Which action should the PN implement in response to the client's refusal?
- A. Emphasize the importance of active foot flexion
- B. Check the surgical dressing
- C. Complete an incident report
- D. Explain the use of an incentive spirometer every 2 hours
Correct Answer: A
Rationale: The correct action for the PN to implement when a client refuses pneumatic compression devices is to emphasize the importance of active foot flexion. Active foot flexion exercises can help prevent deep vein thrombosis (DVT) in clients who are not using the compression devices. Encouraging some form of circulation-promoting activity is crucial to reduce the risks associated with immobility. Checking the surgical dressing (Choice B) is important but not the immediate action to address the refusal of compression devices. Completing an incident report (Choice C) is not necessary in this situation as the client's refusal is not an incident. Explaining the use of an incentive spirometer (Choice D) is not directly related to addressing the refusal of compression devices for DVT prevention.
What is the primary reason for applying sequential compression devices (SCDs) to a patient's legs postoperatively?
- A. To prevent deep vein thrombosis (DVT)
- B. To promote wound healing
- C. To reduce postoperative pain
- D. To maintain body temperature
Correct Answer: A
Rationale: The correct answer is A: To prevent deep vein thrombosis (DVT). Sequential compression devices (SCDs) are used postoperatively to prevent DVT by promoting blood circulation in the legs. This helps reduce the risk of blood clots forming in the deep veins of the legs. Choice B, to promote wound healing, is incorrect as SCDs are primarily used for circulatory purposes rather than wound healing. Choice C, to reduce postoperative pain, is incorrect as the primary purpose of SCDs is not pain management but rather prevention of DVT. Choice D, to maintain body temperature, is incorrect as SCDs are not designed for regulating body temperature but for preventing circulatory issues.
What is the function of the enzyme lactase in the digestive system?
- A. Breaks down lactose into glucose and galactose
- B. Breaks down proteins into amino acids
- C. Converts starch into maltose
- D. Breaks down fats into fatty acids
Correct Answer: A
Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.
In which condition is the 'butterfly rash' most commonly seen?
- A. Systemic lupus erythematosus
- B. Rheumatoid arthritis
- C. Psoriasis
- D. Dermatomyositis
Correct Answer: A
Rationale: The correct answer is A: Systemic lupus erythematosus (SLE). The 'butterfly rash' across the cheeks and nose is a classic sign of SLE, an autoimmune disease. This rash is a key dermatological manifestation of SLE, often triggered or worsened by exposure to sunlight. Choices B, C, and D are incorrect because the 'butterfly rash' is not commonly associated with rheumatoid arthritis, psoriasis, or dermatomyositis.
Which of the following components of nutrition has a primary function of helping with tissue growth and repair?
- A. Vitamin D
- B. Vitamin E
- C. Protein
- D. Fat
Correct Answer: C
Rationale: Protein is the correct answer as it is essential for tissue growth and repair. Proteins are composed of amino acids, the building blocks of body tissues. While vitamins D and E have important roles in the body, they are not primarily responsible for tissue growth and repair. Fats are crucial for various bodily functions, like providing energy, but they are not the primary component involved in tissue growth and repair.
