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. 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.

3. A client with bipolar disorder is being treated with lithium. The nurse should monitor the client for which early sign of lithium toxicity?

• A. Diarrhea
• B. Tremors
• C. Polyuria
• D. Blurred vision

Correct answer: A

Rationale: Corrected Rationale: Diarrhea is an early sign of lithium toxicity. When a client being treated with lithium presents with diarrhea, it can indicate the beginning of lithium toxicity. Monitoring for this symptom is crucial as it can progress to more severe toxicity if not addressed promptly. Tremors (choice B) are more commonly associated with the therapeutic effects of lithium rather than toxicity. Polyuria (choice C) is a common side effect of lithium, but it is not typically an early sign of toxicity. Blurred vision (choice D) is not a common early sign of lithium toxicity. Therefore, option A is the correct answer.

4. The nurse is planning care for a 32-year-old male client diagnosed with HIV infection who has a history of chronic depression. Recently, the client's viral load has begun to increase rather than decrease despite his adherence to the HIV drug regimen. What should the nurse do first while taking the client's history upon admission to the hospital?

• A. Determine if the client attends a support group weekly.
• B. Hold all antidepressant medications until further notice.
• C. Ask the client if he takes St. John's Wort routinely.
• D. Have the client describe any recent changes in mood.

Correct answer: C

Rationale: The nurse's top priority upon admission is to determine if the client has been taking St. John's Wort, an herbal preparation often used for depression. St. John's Wort can interact adversely with medications used to treat HIV infection, potentially explaining the rise in the viral load (C). Asking about attending support groups (A) or recent changes in mood (D) may provide valuable information about the client's depression but is not as critical as determining St. John's Wort use. Holding antidepressant medications (B) without assessing for potential interactions can be harmful to the client.

5. A female client with depression attends a group and states that she sometimes misses her medication appointments because she feels very anxious about riding the bus. Which statement is the nurse's best response?

• A. Can your case manager take you to your appointments?
• B. Take your medication for anxiety before you ride the bus.
• C. Let's talk about what happens when you feel very anxious.
• D. What are some ways that you can cope with your anxiety?

Correct answer: D

Rationale: Encouraging the client to discuss coping mechanisms for anxiety is a supportive approach that empowers the client to manage their symptoms. Choice A may not address the client's self-management and coping skills. Choice B suggests using anxiety medication before riding the bus, which may not be the most appropriate solution. Choice C acknowledges the anxiety but does not actively involve the client in finding solutions, unlike Choice D which promotes client empowerment and self-efficacy.
