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 electrolyte imbalance is most likely to cause cardiac arrhythmias?

• A. Hyperkalemia
• B. Hypocalcemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: A

Rationale: Hyperkalemia is the correct answer as it can lead to dangerous cardiac arrhythmias due to its effects on the electrical conduction of the heart. High levels of potassium can disrupt the normal electrical activity of the heart, potentially leading to life-threatening arrhythmias. Hypocalcemia (choice B) is not the most likely cause of cardiac arrhythmias compared to hyperkalemia. Hypernatremia (choice C), referring to high sodium levels, is not directly associated with causing cardiac arrhythmias. While hypokalemia (choice D), low potassium levels, can also lead to cardiac arrhythmias, hyperkalemia is the more likely culprit in causing severe disturbances in heart rhythm.

3. 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.

4. The HCP gives a pregnant woman a prescription for one prenatal vitamin with iron daily and tells her that she needs to increase foods in her diet because her hemoglobin is 8.2 grams/dL. When a list of iron-rich foods is given to the client, she tells the PN that she is a vegetarian and does not eat anything that "bleeds." Which instruction should the PN provide?

• A. All below
• B. Increase green leafy vegetables in the diet
• C. Oatmeal is a good choice for breakfast
• D. Add lentils and black beans to soup

Correct answer: A

Rationale: Vegetarians can increase their iron intake through plant-based sources such as green leafy vegetables, oatmeal, and legumes, which are rich in iron.

5. Which of the following is a common side effect of opioid analgesics that the nurse should monitor for in patients?

• A. Diarrhea
• B. Hypertension
• C. Constipation
• D. Bradycardia

Correct answer: C

Rationale: Constipation is a common side effect of opioid analgesics due to the slowing of gastrointestinal motility. Opioids bind to receptors in the gastrointestinal tract, leading to decreased peristalsis and increased water absorption, resulting in constipation. Monitoring for constipation is crucial to prevent discomfort or complications like bowel obstruction. Diarrhea (Choice A) is not a common side effect of opioid analgesics. Hypertension (Choice B) and Bradycardia (Choice D) are not typically associated with opioid use.
