Nursing Elites

1. Nurse Wayne is aware that a positive Chvostek's sign indicates:

• A. Hypocalcemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypermagnesemia

Correct answer: A

Rationale: A positive Chvostek's sign indicates hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching due to increased neuromuscular irritability from low calcium levels. Hyponatremia (Choice B) is characterized by low sodium levels, but it does not present with Chvostek's sign. Hypokalemia (Choice C) is low potassium levels, and hypermagnesemia (Choice D) is high magnesium levels, neither of which are associated with Chvostek's sign.

2. Which of the following best describes the nurse's responsibility in obtaining informed consent?

• A. The nurse is responsible for ensuring that the patient understands the procedure and has the opportunity to ask questions.
• B. The nurse should ensure that the patient signs the consent form before the procedure begins.
• C. The nurse is responsible for witnessing the patient sign the consent form and documenting the event.
• D. The nurse should delegate the task of obtaining informed consent to another healthcare provider.

Correct answer: A

Rationale: The correct answer is A. Informed consent is a process where the healthcare provider, in this case, the nurse, ensures that the patient understands the procedure, risks, benefits, and alternatives before they agree to it. The nurse plays a crucial role in facilitating this understanding by explaining the information in a clear and understandable manner and providing the patient with the opportunity to ask questions. Choice B is incorrect because merely obtaining the patient's signature on the consent form does not ensure that the patient truly understands what they are consenting to. Choice C is not fully accurate as the nurse's role goes beyond just witnessing the signature; it involves actively ensuring the patient's comprehension. Choice D is incorrect as the responsibility of obtaining informed consent should not be delegated to another healthcare provider, as it is the nurse's duty to ensure proper communication and understanding with the patient.

3. The nurse is caring for a client with primary adrenal insufficiency (Addison's disease). Which of the following laboratory findings would the nurse expect?

• A. Hypernatremia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hypercalcemia

Correct answer: B

Rationale: In primary adrenal insufficiency (Addison's disease), there is a decrease in aldosterone levels, leading to sodium loss and potassium retention. This imbalance results in hyperkalemia, making choice B the correct answer. Hypernatremia (choice A) is unlikely due to sodium loss. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with primary adrenal insufficiency.

4. A client with type 1 diabetes mellitus is experiencing hypoglycemia. What should the nurse instruct the client to do?

• A. Administer insulin immediately
• B. Consume 15 grams of simple carbohydrates
• C. Drink plenty of water
• D. Avoid eating until symptoms resolve

Correct answer: B

Rationale: When a client with type 1 diabetes mellitus experiences hypoglycemia, the nurse should instruct them to consume 15 grams of simple carbohydrates. This is the recommended initial treatment for hypoglycemia as it helps quickly raise blood sugar levels to alleviate symptoms and prevent complications. Administering insulin immediately (Choice A) would further lower blood sugar levels, worsening the hypoglycemia. Drinking plenty of water (Choice C) and avoiding eating until symptoms resolve (Choice D) are not appropriate actions for treating hypoglycemia as they do not address the immediate need to raise blood sugar levels.

5. Which instruction about insulin administration should Nurse Kate give to a client?

• A. Always follow the same order when drawing up different insulins into the syringe.
• B. Shake the vials before withdrawing the insulin.
• C. Store unopened vials of insulin in the refrigerator at recommended temperatures.
• D. Discard the intermediate-acting insulin if it appears cloudy.

Correct answer: A

Rationale: The correct answer is A. Consistently following the same order when drawing up different insulins helps to prevent medication errors. Option B is incorrect because shaking insulin vials could cause bubbles to form, leading to inaccurate dosing. Option C is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness. Option D is incorrect because cloudy appearance in intermediate-acting insulin may indicate the presence of insulin crystals, which can affect its potency, but this does not necessarily mean it should be discarded without consulting a healthcare provider.
