1. Which condition is characterized by a progressive loss of muscle strength due to an autoimmune attack on acetylcholine receptors?

• A. Myasthenia gravis
• B. Multiple sclerosis
• C. Amyotrophic lateral sclerosis
• D. Guillain-Barré syndrome

Correct answer: A

Rationale: The correct answer is A: Myasthenia gravis. Myasthenia gravis is characterized by muscle weakness caused by autoimmune attack on acetylcholine receptors at the neuromuscular junction. This results in impaired communication between nerves and muscles. Choice B, Multiple sclerosis, is a condition where the immune system attacks the protective myelin sheath covering the nerves in the central nervous system, leading to communication issues between the brain and the rest of the body. Choice C, Amyotrophic lateral sclerosis, is a progressive neurodegenerative disease affecting motor neurons in the brain and spinal cord, not involving acetylcholine receptors. Choice D, Guillain-Barré syndrome, is an acute condition where the immune system attacks the peripheral nerves, causing muscle weakness and paralysis, but it does not target acetylcholine receptors.

2. Which disorder is characterized by demyelination of neurons in the central nervous system?

• A. Multiple sclerosis
• B. Parkinson's disease
• C. Alzheimer's disease
• D. Huntington's disease

Correct answer: A

Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.

3. When administering IV fluids to a client with a history of congestive heart failure (CHF), what is the nurse's primary concern?

• A. Monitoring for signs of fluid overload.
• B. Ensuring the client receives enough fluids to prevent dehydration.
• C. Preventing electrolyte imbalances.
• D. Maintaining the prescribed rate of fluid administration.

Correct answer: A

Rationale: The primary concern when administering IV fluids to a client with a history of congestive heart failure (CHF) is monitoring for signs of fluid overload. Clients with CHF are particularly vulnerable to fluid overload, which can exacerbate their condition. Signs of fluid overload include edema and difficulty breathing. Therefore, the nurse must closely monitor these signs to prevent worsening of the client's condition. Choices B, C, and D are incorrect because while ensuring hydration, preventing electrolyte imbalances, and maintaining the prescribed rate of fluid administration are important, they are secondary concerns compared to the critical task of monitoring for fluid overload in a client with CHF.

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. Which assessment finding would most likely indicate a complication of enteral tube feeding?

• A. Abdominal distension
• B. Weight gain
• C. Decreased bowel sounds
• D. Diarrhea

Correct answer: A

Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.
