1. Which of the following is the most effective way to prevent the spread of infection in a healthcare setting?

• A. Using sterile gloves
• B. Wearing a face mask
• C. Performing hand hygiene
• D. Using disposable equipment

Correct answer: C

Rationale: Performing hand hygiene is the most effective way to prevent the spread of infection in a healthcare setting. Hand hygiene helps remove pathogens that could be transmitted through direct contact, making it a crucial practice in infection control. While using sterile gloves and disposable equipment are important in certain situations, they do not address the potential transmission of pathogens through direct contact, unlike hand hygiene. Wearing a face mask is important for respiratory precautions but may not be as effective as hand hygiene in preventing the spread of infections through direct contact.

2. 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.

3. For an older postoperative client with the nursing diagnosis 'impaired mobility related to fear of falling,' which desired outcome best directs the nurse's actions for the client?

• A. The client will ambulate with assistance every 4 hours
• B. The physical therapist will instruct the client in the use of a walker
• C. The client will use self-affirmation statements to decrease fear
• D. The nurse will place a gait belt on the client prior to ambulation

Correct answer: C

Rationale: Encouraging the client to use self-affirmation statements is the most appropriate desired outcome in this scenario. By utilizing self-affirmation statements, the client can address their fears directly and build confidence, which can ultimately lead to a reduction in fear of falling. While ambulating with assistance (choice A) is important, the focus here is on addressing the fear itself. Instructing the client in the use of a walker (choice B) and placing a gait belt on the client (choice D) are interventions that may be helpful but do not directly address the client's fear of falling.

4. What is the primary function of hemoglobin in red blood cells?

• A. To transport oxygen from the lungs to body tissues
• B. To protect the body from infections
• C. To help in blood clotting
• D. To regulate body temperature

Correct answer: A

Rationale: The primary function of hemoglobin in red blood cells is to transport oxygen from the lungs to body tissues and return carbon dioxide from the tissues to the lungs. Hemoglobin binds to oxygen in the lungs and releases it in the body's tissues. Choice B is incorrect because hemoglobin is not involved in protecting the body from infections. Choice C is incorrect because blood clotting is mainly facilitated by platelets and clotting factors, not hemoglobin. Choice D is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not by hemoglobin.

5. 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.
