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. There has been a serious explosion at a local factory, and many of the injured are arriving at the hospital. Which of the following patients should a nurse attend to first?

• A. A 30-year-old male who is able to walk into the hospital on his own but has numerous lacerations on the chest and face
• B. A 45-year-old male who was brought in on a stretcher, has been assessed as having respiration and circulation within normal limits, and can follow simple commands
• C. A 50-year-old woman who can walk but has a broken arm and numerous lacerations
• D. A 19-year-old man who has numerous lacerations all over the body and whose respiration exceeds 30 breaths per minute

Correct answer: D

Rationale: The correct answer is D. The 19-year-old man with a respiration rate exceeding 30 breaths per minute is showing signs of respiratory distress, indicating a potentially life-threatening condition that requires immediate attention. Patients with respiratory distress should be prioritized as it is a critical condition. Choices A, B, and C describe patients with injuries that are less immediately life-threatening or who are more stable based on the provided information, so they can be attended to after the patient with respiratory distress. Therefore, the nurse should attend to the 19-year-old man first to address his respiratory distress and ensure his condition does not deteriorate further.

3. The client diagnosed with HIV is taught by the nurse that the condition is transmitted through

• A. the infection passed from a mother to her baby
• B. Tears
• C. human bites
• D. insect bites

Correct answer: A

Rationale: HIV can be transmitted from a mother to her baby during childbirth or breastfeeding, making choice A the correct answer. Tears, human bites, and insect bites are not common modes of HIV transmission. While human bites can potentially transmit the virus, it is less common compared to mother-to-child transmission.

4. 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.

5. While caring for a client with a new tracheostomy, the nurse notices that the client is attempting to speak but is unable to. What should the nurse explain to the client regarding their inability to speak?

• A. Speaking is not possible because the tracheostomy tube blocks the vocal cords.
• B. The tracheostomy tube prevents air from reaching the vocal cords, making speech difficult.
• C. The client will regain the ability to speak once the tracheostomy tube is removed.
• D. The tracheostomy tube must be replaced with a speaking valve for the client to speak.

Correct answer: B

Rationale: The correct answer is B. The tracheostomy tube bypasses the vocal cords, preventing air from reaching them, which is necessary for speech. This makes speaking difficult but not impossible. Removing the tracheostomy tube does not automatically restore the ability to speak (choice C). While a speaking valve can be added later to allow speech, initially, the tracheostomy tube itself hinders air from reaching the vocal cords, making speech difficult (choice D is incorrect). Choice A is incorrect as the tracheostomy tube does not block the vocal cords directly; instead, it prevents air from reaching them.
