A nurse is providing dietary teaching to a client who has a new prescription for phenelzine.

Which of the following food recommendations should the nurse make? (Select all that apply.)

Irritability.

The rationale for each choice is as follows:

• A. Irritability: Correct. Irritability is one of the signs of hypoglycemia, which occurs when blood glucose levels fall below 70 mg/dL (3.9 mmol/L). Other signs include shakiness, sweating, hunger, headache, confusion, and blurred vision.
• B. Increased urination: Incorrect. Increased urination is one of the signs of hyperglycemia, which occurs when blood glucose levels rise above 180 mg/dL (10 mmol/L). Other signs include thirst, dry mouth, fatigue, nausea, and fruity breath odor.
• C. Vomiting: Incorrect. Vomiting is not a specific sign of hypoglycemia or hyperglycemia, but it can occur as a complication of either condition if left untreated or poorly managed.
• D.Facial flushing: Incorrect. Facial flushing is not a sign of hypoglycemia or hyperglycemia, but it can occur as a side effect of some medications used to treat diabetes, such as niacin or rosiglitazone.

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.
