Nursing Elites

1. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?

• A. 8 mL/hr
• B. 10 mL/hr
• C. 12 mL/hr
• D. 15 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.

2. A client with a history of diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the LPN/LVN to take?

• A. Monitor the client's blood glucose level.
• B. Encourage the client to increase fluid intake.
• C. Administer insulin as prescribed.
• D. Assess the client's urine output.

Correct answer: A

Rationale: The most important action for the LPN/LVN to take when a client with a history of diabetes mellitus experiences symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps assess the severity of hyperglycemia and guides further interventions. Encouraging the client to increase fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. Administering insulin as prescribed (Choice C) should be done based on the healthcare provider's orders and after assessing the blood glucose levels. Assessing the client's urine output (Choice D) is important but not the most immediate action needed in this scenario.

3. A mother of a child with a neural tube defect asks the nurse what she can do to decrease the chances of having another baby with a neural tube defect. What is the best response by the nurse?

• A. Folic acid should be taken before and after conception.
• B. Multivitamin supplements are recommended during pregnancy.
• C. A well-balanced diet promotes normal fetal development.
• D. Increased dietary iron improves the health of mother and fetus.

Correct answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

4. The healthcare provider is caring for a client who has just been diagnosed with myasthenia gravis. Which symptom should the healthcare provider expect to observe?

• A. Muscle weakness
• B. Joint pain
• C. Vision changes
• D. Skin rash

Correct answer: A

Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).

5. A nurse is caring for a group of clients on a medical-surgical unit. In which of the following situations does the nurse demonstrate the ethical principle of veracity?

• A. A client unaware of her recent cancer diagnosis asks the nurse if she has cancer, and the nurse responds affirmatively.
• B. The nurse avoids discussing the client's diagnosis to prevent emotional distress.
• C. The nurse provides a vague answer about the client's condition.
• D. The nurse promises to provide information only if it is requested by the client.

Correct answer: A

Rationale: Veracity involves telling the truth, a fundamental ethical principle in healthcare. In this scenario, the nurse demonstrates veracity by responding honestly when the client directly asks about her cancer diagnosis. Choice B is incorrect as avoiding discussing the diagnosis to prevent emotional distress does not align with veracity and transparency. Choice C is incorrect as providing a vague answer does not uphold the principle of truthfulness. Choice D is incorrect because promising to provide information only upon client request does not address the immediate question about the cancer diagnosis and lacks transparency.
