Nursing Elites

1. A nurse is caring for a client with lung cancer who is experiencing dyspnea. Which intervention is most appropriate?

• A. Administer a cough suppressant to reduce discomfort.
• B. Encourage the client to lie flat to ease breathing.
• C. Provide supplemental oxygen therapy.
• D. Encourage deep breathing and coughing exercises.

Correct answer: C

Rationale: The most appropriate intervention for a client with lung cancer experiencing dyspnea is to provide supplemental oxygen therapy. This intervention helps improve oxygenation and alleviate breathing difficulties. Administering a cough suppressant (Choice A) may not address the underlying cause of dyspnea and can potentially depress the respiratory drive. Encouraging the client to lie flat (Choice B) can worsen dyspnea by reducing lung expansion. Encouraging deep breathing and coughing exercises (Choice D) may be beneficial in some situations, but when a client is experiencing dyspnea due to lung cancer, supplemental oxygen therapy is the priority to improve oxygen levels and alleviate breathing difficulty.

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 patient is receiving oral nystatin suspension for a fungal infection of the mouth. Which of the following adverse effects is most likely to be experienced with this form of nystatin?

• A. Local irritation
• B. Burning
• C. Nausea
• D. Urinary urgency

Correct answer: A

Rationale: The correct answer is A: Local irritation. When using oral nystatin suspension for a fungal infection of the mouth, local irritation is the most likely adverse effect that a patient may experience. Nystatin is generally well-tolerated, but some patients may develop local irritation, such as mouth or throat irritation. Choices B, C, and D are less likely adverse effects of oral nystatin suspension. Burning, nausea, and urinary urgency are not commonly associated with nystatin use for a fungal infection of the mouth.

4. A client is admitted with a suspected aortic dissection. What is the priority nursing intervention?

• A. Administer antihypertensive medications as prescribed.
• B. Prepare the client for emergency surgery.
• C. Administer intravenous fluids to maintain blood pressure.
• D. Monitor the client's urine output closely.

Correct answer: B

Rationale: The correct answer is B: Prepare the client for emergency surgery. Aortic dissection is a life-threatening emergency that often necessitates immediate surgical intervention to prevent rupture and further complications. Administering antihypertensive medications (choice A) may be necessary but is not the priority over surgical intervention. While maintaining blood pressure with intravenous fluids (choice C) is important, the urgent need for surgery takes precedence. Monitoring urine output (choice D) is essential for assessing renal function but is not the priority in this critical situation.

5. A female patient is concerned about the side effects of hormone replacement therapy (HRT). What common side effect should the nurse explain?

• A. Weight gain
• B. Hair loss
• C. Increased libido
• D. Decreased energy levels

Correct answer: A

Rationale: The correct answer is A: Weight gain. Weight gain is a common side effect of hormone replacement therapy (HRT) due to hormonal changes. Patients should be informed about this possibility as part of their treatment plan. Hair loss (Choice B) is not a common side effect of HRT. Increased libido (Choice C) and decreased energy levels (Choice D) are not typically associated with HRT side effects. Therefore, the nurse should focus on discussing weight gain with the patient.
