Nursing Elites

1. Which of the following is found in higher concentrations within intracellular fluid?

• A. Magnesium
• B. Sodium
• C. Chloride
• D. Bicarbonate

Correct answer: A

Rationale: Magnesium is the correct answer as it is found in higher concentrations within intracellular fluid, where it plays vital roles in various cellular functions. Sodium, chloride, and bicarbonate are predominantly found in extracellular fluid rather than intracellular fluid, making them incorrect choices for this question.

2. 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.

3. The nurse is caring for a client with an astrocytoma. The client asks, 'What do astrocytes do in the brain?' What is the nurse's best response?

• A. Astrocytes help to nourish and support neurons in the brain.
• B. Astrocytes are a type of neuron that transmit electrical signals.
• C. Astrocytes are involved in immune responses in the brain.
• D. Astrocytes help regulate blood flow in the brain.

Correct answer: A

Rationale: Astrocytes play a crucial role in supporting and nourishing neurons by providing metabolic support, maintaining the blood-brain barrier, and regulating the chemical environment of the brain. While astrocytes are essential for brain function, they are not neurons and do not transmit electrical signals (Choice B). Astrocytes are not primarily involved in immune responses in the brain (Choice C) or in regulating blood flow in the brain (Choice D), although they indirectly influence blood flow through their support functions.

4. A patient is prescribed estradiol (Estrace) for hormone replacement therapy (HRT). What should the nurse monitor during this therapy?

• A. Blood glucose levels
• B. Liver function tests
• C. Kidney function tests
• D. Blood pressure

Correct answer: B

Rationale: During estradiol therapy, monitoring liver function tests is essential due to the potential for liver dysfunction. Estradiol can affect liver function, making it crucial to monitor enzyme levels. Choice A, blood glucose levels, is not directly impacted by estradiol therapy, making it an incorrect choice. Choice C, kidney function tests, is not typically affected by estradiol therapy, so it is not the priority for monitoring. Choice D, blood pressure, is also not the primary parameter to monitor during estradiol therapy unless there are pre-existing conditions that warrant such monitoring.

5. How can a colony-stimulating factor affect the patient's erythrocyte count?

• A. It stimulates the growth of red blood cells.
• B. It suppresses T-cell production.
• C. It inhibits protein synthesis.
• D. It stimulates antibody production.

Correct answer: A

Rationale: Colony-stimulating factors are substances that stimulate the production of blood cells in the bone marrow. Erythrocytes are red blood cells, so a colony-stimulating factor would specifically stimulate the growth of red blood cells, leading to an increase in the patient's erythrocyte count. Choice B is incorrect because colony-stimulating factors do not suppress T-cell production. Choice C is incorrect because colony-stimulating factors do not inhibit protein synthesis. Choice D is incorrect because colony-stimulating factors do not stimulate antibody production; they primarily affect the production of blood cells.
