1. What neurotransmitter was first believed to be the cause of schizophrenia?
- A. GABA
- B. Serotonin
- C. Epinephrine
- D. Dopamine
Correct answer: D
Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.
2. A client has a new prescription for digoxin. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime to prevent nausea.
- B. Take this medication with a full glass of milk.
- C. Notify your provider if you experience visual disturbances.
- D. Report any muscle pain to your provider.
Correct answer: C
Rationale: The correct answer is C: 'Notify your provider if you experience visual disturbances.' Visual disturbances can indicate digoxin toxicity, so it is essential for clients taking digoxin to report any changes in vision to their healthcare provider. Option A is incorrect because the timing of digoxin administration is crucial, usually in the morning. Option B is inaccurate because digoxin should not be taken with milk as it can affect its absorption. Option D is not directly associated with digoxin use and should not be the priority instruction for a client on this medication.
3. A community health nurse is assessing an adolescent who is pregnant. Which of the following assessments is the nurse's priority?
- A. Social relationships with peers.
- B. Plans for attending school while pregnant.
- C. Eligibility for Medicaid.
- D. Understanding of infant care.
Correct answer: D
Rationale: The correct answer is D: Understanding of infant care. When assessing a pregnant adolescent, the priority is to ensure that she has the necessary knowledge and skills to care for her newborn. This assessment is crucial in promoting the health and well-being of both the adolescent mother and her baby. Option A, social relationships with peers, though important, is not the priority during this assessment. Option B, plans for attending school while pregnant, is also important but does not take precedence over ensuring the adolescent's understanding of infant care. Option C, eligibility for Medicaid, is important for accessing healthcare services but is not the priority assessment in this scenario.
4. Which of the following is a key aspect of transformational leadership?
- A. Maintaining the status quo
- B. Encouraging innovation
- C. Focus on short-term goals
- D. Top-down communication
Correct answer: B
Rationale: The correct answer is B: Encouraging innovation. Transformational leadership is characterized by inspiring and motivating team members to think creatively, embrace change, and strive for continuous improvement. Choice A is incorrect as transformational leaders seek to challenge the status quo rather than maintain it. Choice C is incorrect because transformational leadership emphasizes long-term vision and goals rather than short-term objectives. Choice D is incorrect as transformational leadership promotes open, two-way communication rather than top-down communication.
5. Your patient has alcoholism, and you may suspect during your assessment that his serum magnesium is low. What will the nurse potentially expect to assess related to hypomagnesemia?
- A. Tremor
- B. Pruritus
- C. Edema
- D. Decreased blood pressure
Correct answer: A
Rationale: The correct answer is A: Tremor. Signs and symptoms of hypomagnesemia primarily affect the neuromuscular system and can include tremors, confusion, tetany, laryngeal stridor, and ataxia. Pruritus (choice B) refers to itching and is not typically associated with hypomagnesemia. Edema (choice C) is swelling caused by fluid retention and is not a common manifestation of hypomagnesemia. Decreased blood pressure (choice D) is not a typical sign of hypomagnesemia; instead, low magnesium levels are more likely to cause hypertension.
