1. What is the most effective method to prevent medication errors during administration?

• A. Relying on memory for medication dosages
• B. Using a bar-code medication administration system
• C. Administering medications as quickly as possible to avoid delays
• D. Allowing another individual to administer medications

Correct answer: B

Rationale: Using a bar-code medication administration system is the best method to prevent medication errors during administration. This system verifies medication details electronically, ensuring that the correct medication is given to the right patient. Relying on memory for medication dosages (choice A) is not recommended as it can lead to errors. Administering medications quickly (choice C) may increase the risk of mistakes due to haste. Allowing another individual (choice D) to administer medications does not address the root cause of preventing errors during administration.

2. 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.

3. What is the primary purpose of performing range-of-motion (ROM) exercises?

• A. To improve cardiovascular fitness
• B. To prevent muscle atrophy and joint contractures
• C. To increase respiratory function
• D. To enhance cognitive function

Correct answer: B

Rationale: The primary purpose of performing range-of-motion (ROM) exercises is to prevent muscle atrophy and joint contractures. These exercises are crucial in maintaining joint mobility and muscle flexibility, especially in patients who are immobilized or have limited mobility. Improving cardiovascular fitness (Choice A) involves different types of exercises that target the heart and blood vessels, not specifically ROM exercises. Increasing respiratory function (Choice C) is typically achieved through breathing exercises and activities that enhance lung capacity. Enhancing cognitive function (Choice D) is usually addressed through cognitive exercises and activities that stimulate brain function.

4. Thirty minutes after receiving IV morphine, a postoperative client continues to rate pain as 7 on a 10-point scale. Which action should the PN implement first?

• A. Call healthcare provider to request a different analgesic
• B. Determine when morphine can be given again
• C. Implement complementary pain relief methods
• D. Observe dressing to determine the presence of bleeding

Correct answer: C

Rationale: The most appropriate action for the PN to implement first is to implement complementary pain relief methods. This includes repositioning the client, applying heat or cold packs, or using relaxation techniques. These strategies can provide additional pain relief before the next dose of medication is due or before seeking further instructions from the healthcare provider. Calling the healthcare provider immediately to request a different analgesic (Choice A) may not be necessary at this moment since other non-pharmacological methods can be attempted first. Determining when morphine can be given again (Choice B) is important but addressing the client's immediate pain relief takes precedence. Observing the dressing for bleeding (Choice D) is important but not the first priority when the client is experiencing unrelieved pain.

5. When caring for a child with sickle cell disease, the PN expects that the child will most likely describe which symptom when experiencing a sickle cell crisis?

• A. Decreased hemoglobin
• B. Joint pain
• C. Fatigue
• D. Infection

Correct answer: B

Rationale: During a sickle cell crisis, a child with sickle cell disease is most likely to describe joint pain. Sickle cell disease leads to the blockage of blood flow by sickled red blood cells, causing ischemia and pain, often felt in the joints and other body parts. Fatigue (choice C) is a nonspecific symptom that can occur in various conditions but is not a characteristic symptom of a sickle cell crisis. While decreased hemoglobin (choice A) can be observed in sickle cell disease, it is not a symptom typically described by a child during a sickle cell crisis. Infection (choice D) can trigger a sickle cell crisis but is not the symptom most likely to be described by the child during the crisis.
