1. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

• A. They have a high energy-to-fluid-volume ratio.
• B. Even though hypertonic, they are well tolerated.
• C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
• D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

2. Which of the following describes the stages of domestic violence in an intimate relationship?

• A. happiness, crisis, angry outburst, intervention
• B. honeymoon period, escalation of stress, outburst, reconciliation
• C. acting out and making up
• D. peace and calm, angry outburst, peace and calm, denial

Correct answer: B

Rationale: The correct answer is B: 'honeymoon period, escalation of stress, outburst, reconciliation.' A pattern of behavior known as the cycle of abuse involves these stages. It starts with a honeymoon phase, followed by a buildup of stress, an outburst which may involve violence, and then reconciliation. This cycle is commonly observed in domestic violence situations. Choices A, C, and D do not accurately represent the stages of domestic violence in intimate relationships. Choice A mixes positive and negative elements, while choice C simplifies the complex dynamics of domestic violence. Choice D repeats 'peace and calm' inappropriately and includes 'denial,' which is not typically a stage in the cycle of abuse.

3. The client with cirrhosis of the liver is receiving Lactulose. The nurse is aware that the rationale for the order for Lactulose is:

• A. To lower the blood glucose level
• B. To lower the uric acid level
• C. To lower the ammonia level
• D. To lower the creatinine level

Correct answer: C

Rationale: Lactulose is administered to the client with cirrhosis to lower ammonia levels, as it works by acidifying the colon, trapping ammonia for elimination in the stool. Choices A, B, and D are incorrect because Lactulose does not have an effect on blood glucose, uric acid, or creatinine levels. Therefore, the correct answer is to lower the ammonia level.

4. How should Lasix be administered to prevent hypotension?

• A. By administering it over 1-2 minutes
• B. By hanging it IV piggyback
• C. With normal saline only
• D. By administering it through a venous access device

Correct answer: A

Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.

5. A client is taking hydrocodone (Vicodin) for chronic back pain. The client has required an increase in the dose and asks whether this means he is addicted to Vicodin. The nurse should base her reply on the knowledge that:

• A. the client's body has developed tolerance, requiring more drug to produce the same effect
• B. the client is preoccupied with getting the drug and is experiencing loss of control, indicating drug dependence
• C. addiction involves psychological behaviors related to substance use, not just physical dependence
• D. the client is coping with chronic back pain and requires adjustments in the medication regimen

Correct answer: A

Rationale: When a client requires an increased dose of a drug, such as in this case with hydrocodone, it suggests that the body has developed tolerance to the medication. Tolerance means that the client needs more of the drug to achieve the same effect as before. This does not inherently indicate addiction, which involves psychological behaviors related to substance use. Choice B describes drug dependence, where the client is preoccupied with obtaining the drug and experiences loss of control, which is not the same as tolerance. Choice C correctly points out that addiction is more than just physical dependence with withdrawal symptoms and tolerance; it includes psychological factors. Choice D is irrelevant as it discusses adjusting the medication for pain management, not addressing the client's concern about addiction.
