A nurse is reviewing the results of laboratory screenings for a 9-month-old infant.
Which of the following results should the nurse report to the provider?
Lead 18 mcg/dL.
Hemoglobin 12 g/dL.
Iron 74 mcg/dL.
Hematocrit 35%.
The Correct Answer is A
Choice A rationale:
A blood lead level of 18 mcg/dL in a 9-month-old infant is elevated. The Centers for Disease Control and Prevention (CDC) considers a blood lead level of 5 mcg/dL or higher in children to be concerning. Lead exposure can lead to developmental delays and cognitive impairments. Therefore, this result needs to be reported to the healthcare provider promptly.
Choice B rationale:
Hemoglobin level of 12 g/dL is within the normal range for a 9-month-old infant (11-15 g/dL) There is no need to report this result to the provider.
Choice C rationale:
Iron level of 74 mcg/dL is within the normal range for a 9-month-old infant (50-120 mcg/dL) There is no need to report this result to the provider.
Choice D rationale:
Hematocrit level of 35% is within the normal range for a 9-month-old infant (29-41%) There is no need to report this result to the provider.

Correct Answer is A
Explanation
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
Move the client to a room near the nurses' station.
- A. Keep the client's television on with the volume low: This is incorrect because it does not address the client's safety or agitation. The television might also be a source of confusion or stimulation for the client.
- B. Insert an indwelling urinary catheter to minimize interaction with the client: This is incorrect because it is an invasive and unnecessary procedure that increases the risk of infection and trauma. It also violates the client's dignity and autonomy.
- C. Consult the provider regarding administering a mild sedative on a schedule: This is incorrect because it is not the first action to take. The nurse should first assess the client's condition and identify possible causes of disorientation and combativeness, such as pain, infection, medication side effects, or delirium. Sedatives should be used as a last resort and only with informed consent.
- D. Move the client to a room near the nurses' station: This is correct because it allows for close observation and supervision of the client, which can prevent injury and promote safety. It also facilitates frequent interaction and reassurance from the staff, which can reduce anxiety and agitation.
