Nursing Elites

1. A client with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?

• A. Administer intravenous insulin
• B. Start an intravenous line and infuse normal saline
• C. Monitor serum potassium levels
• D. Obtain an arterial blood gas (ABG)

Correct answer: B

Rationale: The correct first intervention in the treatment of a client with diabetic ketoacidosis (DKA) is to start an intravenous line and infuse normal saline. This is essential for fluid resuscitation to restore intravascular volume and improve perfusion. Administering intravenous insulin can lead to further potassium depletion without first addressing dehydration and electrolyte imbalances. Monitoring serum potassium levels is important but should follow fluid resuscitation to avoid life-threatening hypokalemia. Obtaining an arterial blood gas (ABG) is necessary to assess the acid-base status but is not the initial priority when managing DKA.

2. The client with hyperparathyroidism is being taught about dietary management. Which of the following foods should the client avoid?

• A. Bananas
• B. Spinach
• C. Milk
• D. Processed meats

Correct answer: C

Rationale: Clients with hyperparathyroidism should avoid high-calcium foods like milk because they already have elevated calcium levels. Bananas and spinach are not high in calcium and can be included in the diet. Processed meats are not specifically contraindicated in hyperparathyroidism, so they are not the correct answer.

3. A nurse manager conducts evaluations with each staff member and reviews the staffing needs for the upcoming year. Which of the following best describes the behavior this manager is engaging in?

• A. Interpersonal activities
• B. Decisional activities
• C. Informational activities
• D. Transformational activities

Correct answer: B

Rationale: The correct answer is B: Decisional activities. A nurse manager conducting evaluations and reviewing staffing needs for the future involves making decisions related to resource allocation, planning, and problem-solving. These activities fall under the category of decisional activities in management. Choice A, Interpersonal activities, would involve activities like communicating, motivating, and leading staff. Choice C, Informational activities, would involve activities like gathering and disseminating information. Choice D, Transformational activities, would involve inspiring and motivating staff to achieve organizational goals through vision and change.

4. 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.

5. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.
