A nurse is reinforcing teaching with a client who has a new diagnosis of myasthenia gravis (MG) and a prescription for neostigmine. Which of the following information should the nurse include about the action of the medication?
Improves muscle strength.
Destroys the antibodies that cause MG
Enhances immune system function
Prevents excessive coughing
The Correct Answer is A
a. Improves muscle strength.
Explanation:
Neostigmine is a medication used in the treatment of myasthenia gravis (MG). It belongs to a class of drugs called cholinesterase inhibitors. Neostigmine works by inhibiting the breakdown of acetylcholine, a neurotransmiter involved in muscle contraction. In MG, there is a decrease in the amount of acetylcholine available at the neuromuscular junction, leading to muscle weakness and fatigue.
By inhibiting the breakdown of acetylcholine, neostigmine helps to increase the concentration of acetylcholine at the neuromuscular junction. This, in turn, improves muscle strength and can alleviate the symptoms of weakness and fatigue associated with MG.
Option b, destroying the antibodies that cause MG, is not accurate. Myasthenia gravis is an autoimmune disorder characterized by the presence of antibodies that interfere with neuromuscular transmission.
Neostigmine does not directly target or eliminate these antibodies.
Option c, enhancing immune system function, is not accurate either. Neostigmine primarily acts on the neuromuscular junction to improve muscle strength and does not have a direct effect on immune system function.
Option d, preventing excessive coughing, is not the primary action of neostigmine. While increased muscle strength may indirectly improve respiratory function and reduce coughing in individuals with myasthenia gravis, it is not the primary indication or action of neostigmine.
Therefore, the most accurate information to include in teaching about neostigmine for a client with myasthenia gravis is that it improves muscle strength.

Correct Answer is D
Explanation
The correct answer is D
Choice A Reason: While croup can be serious, an O2 saturation of 92% on room air is generally stable. This child's condition is concerning but not immediately life-threatening.
Choice B Reason: A 15-year-old adolescent who is 2 hours postoperative following an open reduction and internal fixation of the left ankle and is requesting pain medication is in need of comfort measures. Postoperative pain management is important for recovery, but it is not a priority over more critical conditions.
Choice C Reason: A 3-year-old toddler with gastroenteritis, moderate dehydration, and two loose bowel movements over the past 24 hours requires rehydration and monitoring. The normal range for bowel movements varies, but two loose stools in 24 hours for a toddler with gastroenteritis is not unusual. Dehydration can become severe, so this child should be assessed soon, but it is not the most urgent case.
Choice D Reason: This child's sudden relief from pain could be a sign of a perforated appendix, a serious complication that requires immediate medical attention. Therefore, this child's condition is the most urgent and requires immediate assessment.
Correct Answer is A
Explanation
Choice A rationale:
Irritability is a common withdrawal symptom in newborns exposed to cocaine during pregnancy. Cocaine exposure can lead to irritability, restlessness, and difficulty in consoling the newborn.
Choice B rationale:
Hypotonicity, or decreased muscle tone, is not a common finding associated with cocaine exposure in newborns. Cocaine exposure more commonly results in hypertonicity, where the muscles are tense and rigid.
Choice C rationale:
Decreased auditory startle response is not a typical finding associated with cocaine exposure. Newborns exposed to cocaine may have an exaggerated startle response, which is the opposite of the expected finding in this case.
Choice D rationale:
Increased head circumference is not a characteristic finding associated with cocaine exposure. Cocaine exposure is more likely to cause growth restriction, low birth weight, and microcephaly (small head size) in newborns.
