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. A client with type 1 DM is admitted to the hospital with diabetic ketoacidosis (DKA). The nurse should prioritize which action?

• A. Administering intravenous fluids.
• B. Administering oral glucose.
• C. Administering a fever-reducing medication.
• D. Administering oxygen therapy.

Correct answer: A

Rationale: Administering intravenous fluids is the priority in treating DKA for several reasons. DKA is characterized by severe dehydration and electrolyte imbalances due to hyperglycemia. IV fluids help to correct dehydration, restore electrolyte balance, and decrease blood glucose levels. Administering oral glucose (Choice B) would be contraindicated in DKA as the primary issue is high blood glucose levels. Administering a fever-reducing medication (Choice C) is not the priority in managing DKA. Administering oxygen therapy (Choice D) may be necessary in some cases, but correcting dehydration and electrolyte imbalances take precedence in the management of DKA.

3. Early this morning, a female client had a subtotal thyroidectomy. During evening rounds, Nurse Tina assesses the client, who now has nausea, a temperature of 105°F (40.5°C), tachycardia, and extreme restlessness. What is the most likely cause of these signs?

• A. Diabetic ketoacidosis
• B. Thyroid crisis
• C. Hypoglycemia
• D. Tetany

Correct answer: B

Rationale: The correct answer is B: Thyroid crisis. Thyroid crisis, also known as thyroid storm, is a life-threatening condition that can occur after a thyroidectomy. Symptoms include high fever, tachycardia, extreme restlessness, and other signs of severe hyperthyroidism. Diabetic ketoacidosis (choice A) is a complication of diabetes characterized by hyperglycemia, ketosis, and acidosis, not typically seen post-thyroidectomy. Hypoglycemia (choice C) is low blood sugar levels and would not present with the symptoms described. Tetany (choice D) is a condition of involuntary muscle spasms due to low calcium levels and is not directly related to the symptoms observed in this scenario.

4. A client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor the client for which of the following potential side effects?

• A. Hypoglycemia
• B. Hypertension
• C. Weight loss
• D. Hyperkalemia

Correct answer: B

Rationale: When a client with Addison's disease is receiving corticosteroid therapy, the nurse should monitor for hypertension as a potential side effect. Corticosteroids can lead to hypertension by causing fluid retention and increased blood volume. Hypoglycemia (Choice A) is not a common side effect of corticosteroid therapy; instead, hyperglycemia is more likely. Weight loss (Choice C) is not a typical side effect of corticosteroid therapy; in fact, weight gain is more common due to fluid retention and increased appetite. Hyperkalemia (Choice D) is a potential side effect of Addison's disease itself due to adrenal insufficiency, but it is not directly caused by corticosteroid therapy.

5. A client with hypothyroidism is prescribed levothyroxine. The nurse should teach the client to take this medication:

• A. With meals
• B. Before bedtime
• C. On an empty stomach in the morning
• D. With a glass of milk

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance absorption and efficacy. Taking it with meals (Choice A) may interfere with absorption due to food interactions. Taking it before bedtime (Choice B) can lead to difficulties with absorption and may disrupt the sleep cycle. Consuming levothyroxine with a glass of milk (Choice D) is not recommended as calcium in milk can interfere with its absorption. Therefore, the best practice is to take levothyroxine on an empty stomach in the morning to ensure optimal effectiveness.
