A 6-year-old was complaining of elbow pain.
The nurse will advise the patient to give which pain medication?

Choice A rationale

Treatment of narcotic dependence involves using a narcotics antagonist to block the effects of narcotics. This helps prevent relapse in patients recovering from narcotic addiction by decreasing cravings and withdrawal symptoms.

Choice B rationale

Treatment of alcohol dependence does not typically involve narcotics antagonists. Instead, medications like disulfiram or naltrexone are used to manage alcohol dependence.

Choice C rationale

Reversal of tachycardia is not an indication for a narcotics antagonist. Tachycardia is usually managed with medications like beta-blockers or calcium channel blockers.

Choice D rationale

Reversal of bronchoconstriction is not an indicator for narcotics antagonists. Bronchoconstriction is usually treated with bronchodilators such as albuterol or ipratropium.

Choice A rationale

Myasthenia gravis primarily affects voluntary muscles, especially those involved in breathing and facial movements. Gastrointestinal (GI) and lower extremity muscles are generally not the main muscles affected by this condition. It is an autoimmune disorder that impacts the neuromuscular junction, where nerves communicate with muscles, leading to muscle weakness and fatigue.

Choice B rationale

The central nervous system (CNS), memory, and cognition are not typically impacted by myasthenia gravis. This disorder primarily involves peripheral nervous system issues that affect voluntary muscle control rather than cognitive functions. Myasthenia gravis does not cause alterations in memory or cognition as seen with central nervous system disorders like Alzheimer's disease.

Choice C rationale

Myasthenia gravis notably affects respiratory and facial muscles. The autoimmune attack on acetylcholine receptors leads to muscle weakness, particularly in muscles controlling eye movements, facial expressions, and breathing. Patients may experience difficulty breathing, swallowing, and maintaining an open airway due to this muscle weakness.

Choice D rationale

The cardiovascular system and postural muscles are not commonly affected by myasthenia gravis. This condition involves the neuromuscular junction and leads to fatigue in voluntary muscles, primarily those involved in eye movement, facial expressions, and respiration. Cardiovascular symptoms are not a direct consequence of myasthenia gravis.
