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. Inspiratory and expiratory stridor may be heard in a client who:

• A. Is experiencing an exacerbation of goiter
• B. Is experiencing an acute asthmatic attack
• C. Has aspirated a piece of meat
• D. Has severe laryngotracheitis

Correct answer: D

Rationale: Inspiratory and expiratory stridor are high-pitched, wheezing sounds caused by disrupted airflow due to airway obstruction. Severe laryngotracheitis, involving inflammation and swelling of the larynx and trachea, leads to airway obstruction and can produce both inspiratory and expiratory stridor. Exacerbation of goiter, an acute asthmatic attack, and aspiration of a piece of meat are not typically associated with both inspiratory and expiratory stridor. Therefore, choices A, B, and C are incorrect.

3. 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.

4. A new mother who is breastfeeding her newborn for the first time after delivery reports nipple pain when the baby sucks. Based on this client problem, which action should the PN take?

• A. Ensure that all the areolar tissue of the nipple is in the infant's mouth
• B. Have the mother reposition the infant from the cradle to the football hold
• C. Check for engorgement and assess the nipples for cracks or lesions
• D. Apply a warm compress to the breast for 10 minutes before each feeding

Correct answer: A

Rationale: Proper latch, including all the areolar tissue in the infant's mouth, is essential to prevent nipple pain and ensure effective breastfeeding. Option A is correct because ensuring that all the areolar tissue of the nipple is in the infant's mouth helps achieve a good latch, reducing nipple pain. Option B is incorrect as repositioning the infant may not address the root cause of the pain related to latch issues. Option C is incorrect because while checking for engorgement and nipple issues is important, it does not directly address the latch concern causing the pain. Option D is incorrect as applying a warm compress is not recommended for breastfeeding mothers; a warm compress can help with pain associated with engorgement, but it does not address latch issues.

5. A female Native American client who is receiving chemotherapy places a native artifact, an Indian medicine wheel, in her hospital room. The HCP removes the medicine wheel and tells the client, 'This type of thing does not belong in the hospital.' Which intervention should the PN implement?

• A. Teach the client about the importance of adhering to the chemotherapy regimen
• B. Act as the client's advocate when addressing the issue with the HCP
• C. Consult with a Native American healer about the appropriate use of a medicine wheel
• D. Inform the HCP about the client's feelings of culture shock

Correct answer: B

Rationale: Acting as the client's advocate is the most appropriate intervention in this situation. Removing a culturally significant artifact without considering the client's beliefs and emotional needs can be distressing. By advocating for the client, the PN can ensure that the client's cultural practices are respected, which is crucial for her emotional and spiritual well-being during treatment. Choice A is incorrect because while chemotherapy adherence is important, it is not the most immediate concern in this scenario. The client's cultural needs and well-being take precedence. Choice C is incorrect because consulting with a Native American healer might not be necessary at this point and could delay addressing the immediate issue of advocating for the client's rights. Choice D is incorrect because simply reporting the client's feelings of culture shock to the HCP does not actively address the situation or advocate for the client's rights and cultural needs.
