Nursing Elites

1. A client is scheduled to complete a positron emission tomography (PET) scan. The client asks the nurse to explain the reason the test was prescribed. How should the nurse respond?

• A. Images indicate the presence of tumors and scars.
• B. The scan clearly outlines structures of the brain.
• C. Results show activity in various portions of the brain.
• D. PET shows biochemical levels of neurotransmitters.

Correct answer: C

Rationale: The correct answer is C. PET scans are primarily used to detect and observe the metabolic activity in various parts of the brain. This helps in diagnosing conditions related to brain function, such as tumors, brain disorders, and overall brain activity. Choices A, B, and D are incorrect because PET scans focus on metabolic activity and functions in the brain rather than solely indicating the presence of tumors, outlining brain structures, or showing biochemical levels of neurotransmitters.

2. When planning care for a client with anorexia nervosa, which goal should be prioritized?

• A. The client will establish normal eating patterns.
• B. The client will verbalize feelings about food and weight.
• C. The client will gain a minimum of 2 pounds per week.
• D. The client will achieve normal electrolyte balance.

Correct answer: D

Rationale: The correct answer is D because achieving normal electrolyte balance is critical in clients with anorexia nervosa. Electrolyte imbalances can lead to serious, life-threatening complications such as cardiac arrhythmias and organ failure. While establishing normal eating patterns (choice A) and verbalizing feelings about food and weight (choice B) are important aspects of treatment, addressing electrolyte balance takes precedence due to the immediate risks associated with imbalances. Additionally, setting a weight gain goal of 2 pounds per week (choice C) may not be appropriate initially as rapid refeeding can also lead to electrolyte imbalances and other complications.

3. A client with major depressive disorder is started on fluoxetine (Prozac). What should the nurse include in the client's discharge teaching?

• A. It may take 4-6 weeks for the medication to be effective.
• B. You should take this medication at bedtime.
• C. Avoid consuming dairy products while taking this medication.
• D. You can stop taking the medication once you feel better.

Correct answer: A

Rationale: The correct answer is A: "It may take 4-6 weeks for the medication to be effective." SSRIs like fluoxetine typically take 4-6 weeks to reach their full effect, so clients should be informed to expect a gradual improvement in symptoms. Choice B is incorrect because fluoxetine is usually taken in the morning to prevent sleep disturbances. Choice C is incorrect as there is no specific need to avoid consuming dairy products while taking fluoxetine. Choice D is incorrect because clients should never stop taking antidepressants abruptly, as it can lead to withdrawal symptoms and worsening of the condition.

4. 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.

5. A client with obsessive-compulsive disorder (OCD) spends several hours a day washing his hands. What is the most therapeutic nursing intervention?

• A. Allow the client to continue the behavior to reduce anxiety.
• B. Schedule specific times for handwashing.
• C. Encourage the client to discuss the thoughts and feelings behind the behavior.
• D. Restrict the client's access to soap and water.

Correct answer: C

Rationale: Encouraging the client to discuss the thoughts and feelings behind the behavior is the most therapeutic nursing intervention for a client with OCD who excessively washes hands. This approach can help the client understand the underlying reasons for the behavior, address the associated anxiety, and work toward behavior modification. Choices A, allowing the behavior to continue, and D, restricting access to soap and water, do not address the root cause of the behavior and may exacerbate anxiety. Choice B, scheduling specific times for handwashing, does not address the underlying emotional factors contributing to the behavior and may not effectively reduce the client's anxiety.
