1. Which statement best describes the concept of health equity?
- A. Ensuring equal access to health services for all individuals
- B. Eliminating health disparities among different populations
- C. Focusing on individual health behaviors
- D. Providing high-quality health care
Correct answer: A
Rationale: Health equity is achieved when all individuals have equal access to health services, regardless of their background or circumstances. This means removing barriers to healthcare access and addressing social determinants of health to ensure everyone has the opportunity to attain their highest level of health.
2. The neurotransmitter GABA mainly functions to trigger inhibitory postsynaptic potentials (IPSPs). Therefore, when explaining this to a group of nursing students, the nurse will state:
- A. It takes at least three chemical substances (amino acids, neuropeptides, and monoamines) to stimulate any activity between the cells.
- B. There is a symbiotic relationship; therefore, the end result will be depolarization of the postsynaptic membrane.
- C. The combination of GABA with a receptor site is inhibitory since it causes the local nerve membrane to become hyperpolarized and less excitable.
- D. The neurotransmitters will interact with cholinergic receptors to bind to acetylcholine in order to produce hypopolarization within the cell.
Correct answer: C
Rationale: When GABA binds with a receptor site, it causes hyperpolarization of the local nerve membrane, making it less excitable. This hyperpolarization leads to inhibition of nerve cell activity. Choice A is incorrect because GABA is a neurotransmitter itself and does not require three chemical substances to stimulate activity between cells. Choice B is incorrect as GABA triggers inhibitory postsynaptic potentials (IPSPs), leading to hyperpolarization, not depolarization, of the postsynaptic membrane. Choice D is also incorrect as it describes a process involving cholinergic receptors and acetylcholine, which is unrelated to GABA's mechanism of action.
3. A client with heart failure is prescribed digoxin. Which statement by the client indicates an adverse effect of the medication?
- A. I can walk a mile a day.
- B. I've had a backache for several days.
- C. I am urinating more frequently.
- D. I feel nauseated and have no appetite.
Correct answer: D
Rationale: Nausea and loss of appetite are common early signs of digoxin toxicity, indicating an adverse effect of the medication. These symptoms should be reported to the healthcare provider immediately for further evaluation and management.
4. A nurse in an emergency department is assessing a newly admitted client who is experiencing drooling and hoarseness following a burn injury. Which of the following actions should the nurse take first?
- A. Obtain a baseline ECG
- B. Obtain a blood specimen for ABG analysis
- C. Insert an 18-gauge IV catheter
- D. Administer 100% humidified oxygen
Correct answer: D
Rationale: In a client experiencing drooling and hoarseness following a burn injury, the priority action for the nurse is to administer 100% humidified oxygen. This is crucial to maintain the airway and address respiratory distress, which takes precedence over obtaining an ECG, collecting blood for ABG analysis, or inserting an IV catheter. Providing oxygen therapy is essential in ensuring the client's oxygenation and respiratory function are optimized in this emergency situation.
5. What intervention would be the most important for the nurse to implement for the client with a left nephrectomy?
- A. Assess the intravenous fluids for rate and volume
- B. Change the surgical dressing every day at the same time
- C. Monitor the client’s medication levels daily
- D. Monitor the percentage of each meal eaten
Correct answer: A
Rationale: The most important intervention for a client with a left nephrectomy is to assess the intravenous fluids for rate and volume. After nephrectomy, monitoring intravenous fluids is crucial to ensure proper hydration and kidney function. Changing the surgical dressing daily, monitoring medication levels, and tracking meal intake are also important aspects of care but not as critical as ensuring adequate intravenous fluid management post-surgery.
