Nursing Elites

1. What are neurotransmitters?

• A. Chemical messengers that cause brain cells to turn on or off.
• B. Areas of the brain that are responsible for controlling emotions.
• C. Clumps of cells that alert the other brain cells to receive messages.
• D. Web-like structures that provide connections among parts of the brain.

Correct answer: A

Rationale: Neurotransmitters are chemicals in the brain that act as messengers between neurons, influencing various psychological functions. Choice A correctly defines neurotransmitters by stating that they are chemical messengers that cause brain cells to turn on or off. This is the function of neurotransmitters in transmitting signals between neurons. Choices B, C, and D are incorrect because they do not accurately describe neurotransmitters and their role in the brain.

2. A 72-year-old female client is admitted to the psychiatric unit with a diagnosis of major depression. Which statement by the client should be of greatest concern to the nurse and require further assessment?

• A. "I will die if my cat dies."
• B. "I don't feel like eating this morning."
• C. "I just went to my friend's funeral."
• D. "Don't you have more important things to do?"

Correct answer: A

Rationale: Sometimes a client will use an analogy to describe themselves, and (A) would be an indication for conducting a suicide assessment. (B) could have a variety of etiologies, and while further assessment is indicated, this statement does not indicate potential suicide. The normal grief process differs from depression, and at this client's age, peer/cohort deaths are more frequent, so (C) would be within normal limits. (D) is an expression of low self-esteem typical of depression. Choices (B), (C), and (D) are examples of decreased energy and mood levels which would negate suicide ideation at this time.

3. A homeless person who is in the manic phase of bipolar disorder is admitted to the mental health unit. Which laboratory finding obtained on admission is most important for the nurse to report to the healthcare provider?

• A. Decreased thyroid stimulating hormone level
• B. Elevated liver function profile
• C. Increased white blood cell count
• D. Decreased hematocrit and hemoglobin levels

Correct answer: A

Rationale: The correct answer is A: Decreased thyroid stimulating hormone level. Hyperthyroidism causes an increased level of serum thyroid hormones (T3 and T4), which inhibit the release of TSH. In this case, a decreased TSH level can indicate hyperthyroidism, which can present with manic behavior. Elevated liver function profile (B) is not directly related to the manic phase of bipolar disorder. Increased white blood cell count (C) typically indicates an infection or inflammation, not directly related to the manic phase. Decreased hematocrit and hemoglobin levels (D) may suggest anemia but are not as crucial in the context of a manic phase of bipolar disorder.

4. An adult male client who was admitted to the mental health unit yesterday tells the nurse that microchips were planted in his head for military surveillance of his every move. Which response is best for the nurse to provide?

• A. You are in the hospital, and I am the nurse caring for you
• B. It must be difficult for you to control your anxious feelings
• C. Go to occupational therapy and start a project
• D. You are not in a war area now; this is the United States

Correct answer: C

Rationale: Delusions often generate fear and isolation, so the nurse should help the client participate in activities that avoid focusing on the false belief and encourage interaction with others.

5. A client with schizophrenia is being treated with clozapine (Clozaril). What is the most important laboratory test for the LPN/LVN to monitor?

• A. White blood cell count.
• B. Liver function tests.
• C. Blood glucose levels.
• D. Platelet count.

Correct answer: A

Rationale: The most important laboratory test for an LPN/LVN to monitor for a client with schizophrenia being treated with clozapine is the white blood cell count. Clozapine treatment is associated with a risk of agranulocytosis, a severe drop in white blood cells, which can be life-threatening. Monitoring the white blood cell count regularly helps to detect this adverse effect early. Liver function tests (Choice B) are important to monitor with some antipsychotic medications but are not the most crucial for clozapine. Blood glucose levels (Choice C) are more relevant for monitoring in clients on medications like atypical antipsychotics that can cause metabolic side effects. Platelet count (Choice D) is not typically affected by clozapine therapy and is not the most important test to monitor in this case.
