Nursing Elites

1. Which neurotransmitter is most closely associated with mood regulation and is targeted by antidepressants?

• A. Serotonin
• B. Dopamine
• C. GABA
• D. Acetylcholine

Correct answer: A

Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.

2. For an older postoperative client with the nursing diagnosis 'impaired mobility related to fear of falling,' which desired outcome best directs the nurse's actions for the client?

• A. The client will ambulate with assistance every 4 hours
• B. The physical therapist will instruct the client in the use of a walker
• C. The client will use self-affirmation statements to decrease fear
• D. The nurse will place a gait belt on the client prior to ambulation

Correct answer: C

Rationale: Encouraging the client to use self-affirmation statements is the most appropriate desired outcome in this scenario. By utilizing self-affirmation statements, the client can address their fears directly and build confidence, which can ultimately lead to a reduction in fear of falling. While ambulating with assistance (choice A) is important, the focus here is on addressing the fear itself. Instructing the client in the use of a walker (choice B) and placing a gait belt on the client (choice D) are interventions that may be helpful but do not directly address the client's fear of falling.

3. 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.

4. A nurse is completing a focused assessment of an older adult's skin. The nurse notes a crusted 0.7 cm lesion on the client's forehead. Which action should the nurse take in response to this finding?

• A. Report the finding to the healthcare provider
• B. Place a clear occlusive dressing over the site
• C. Apply a warm compress to remove the crusted area
• D. Explain that this is a normal skin change with aging

Correct answer: A

Rationale: A crusted lesion, especially in an older adult, could be indicative of skin cancer or another serious condition. Therefore, reporting this finding to the healthcare provider is crucial for further evaluation and appropriate management. Placing an occlusive dressing (Choice B) could prevent proper assessment and treatment. Applying a warm compress (Choice C) may not be suitable for a suspicious skin lesion as it could worsen the condition. Explaining it as a normal skin change (Choice D) without proper evaluation can delay necessary interventions and potentially harm the patient.

5. A post-operative client develops a sudden onset of chest pain and dyspnea. The nurse suspects a pulmonary embolism (PE). What is the priority nursing action?

• A. Administer oxygen via face mask.
• B. Elevate the client's legs.
• C. Prepare the client for immediate surgery.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: Administering oxygen via face mask is the priority nursing action in a post-operative client suspected of a pulmonary embolism. This intervention helps ensure adequate oxygenation while further assessments and interventions are initiated. Elevating the client's legs is not indicated for a suspected pulmonary embolism; it is more appropriate for conditions like shock. Immediate surgery is not the priority in this situation as the client is experiencing acute symptoms requiring prompt intervention. While notifying the healthcare provider is important, the immediate focus should be on providing oxygen to the client to support respiratory function.
