Nursing Elites

1. When administering IV fluids to a client with a history of congestive heart failure (CHF), what is the nurse's primary concern?

• A. Monitoring for signs of fluid overload.
• B. Ensuring the client receives enough fluids to prevent dehydration.
• C. Preventing electrolyte imbalances.
• D. Maintaining the prescribed rate of fluid administration.

Correct answer: A

Rationale: The primary concern when administering IV fluids to a client with a history of congestive heart failure (CHF) is monitoring for signs of fluid overload. Clients with CHF are particularly vulnerable to fluid overload, which can exacerbate their condition. Signs of fluid overload include edema and difficulty breathing. Therefore, the nurse must closely monitor these signs to prevent worsening of the client's condition. Choices B, C, and D are incorrect because while ensuring hydration, preventing electrolyte imbalances, and maintaining the prescribed rate of fluid administration are important, they are secondary concerns compared to the critical task of monitoring for fluid overload in a client with CHF.

2. 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.

3. A client post-lobectomy is placed on mechanical ventilation. The nurse notices the client is fighting the ventilator. What should the nurse do first?

• A. Increase the sedation as prescribed.
• B. Manually ventilate the client using an ambu bag.
• C. Check the ventilator settings and alarms.
• D. Suction the client’s airway.

Correct answer: C

Rationale: The correct first action for the nurse to take when a client is fighting the ventilator is to check the ventilator settings and alarms. This step is crucial to ensure that the ventilator is functioning correctly and providing the necessary support to the client. Increasing sedation (Choice A) should only be considered after confirming that the ventilator settings are appropriate. While manually ventilating the client (Choice B) may be required in some cases, it is not the initial action to take. Suctioning the client's airway (Choice D) is not the priority in this situation, where the primary concern is addressing the client's struggle with the ventilator.

4. What is the function of the epiglottis during swallowing?

• A. Prevents food from entering the trachea
• B. Aids in food propulsion
• C. Enhances taste sensation
• D. Lubricates the esophagus

Correct answer: A

Rationale: The epiglottis is a flap of tissue that closes over the trachea during swallowing to prevent food and liquids from entering the airway. Choice A is correct because the primary function of the epiglottis is to act as a lid over the trachea, ensuring that food goes down the esophagus and not into the windpipe. Choices B, C, and D are incorrect as they do not describe the specific role of the epiglottis during swallowing.

5. Which disorder is characterized by demyelination of neurons in the central nervous system?

• A. Multiple sclerosis
• B. Parkinson's disease
• C. Alzheimer's disease
• D. Huntington's disease

Correct answer: A

Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.
