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 psychological contract exists between staff members and nurse managers. Which of the following best describes this relationship?

• A. Nurse managers provide positive evaluations, and in turn, staff members do what managers ask of them.
• B. Nurse managers coordinate multiple departments and supervise multiple staff members.
• C. Staff members do what managers ask of them and, in turn, are rewarded through assignments, promotions, and evaluations.
• D. Nurse managers advocate for staff and support nursing roles and ethical practice.

Correct answer: C

Rationale: The correct answer is C. In a psychological contract between staff members and nurse managers, staff members are expected to fulfill the requests of managers, and in return, they are rewarded with assignments, promotions, and evaluations. This reciprocal relationship forms the basis of the psychological contract. Choices A, B, and D are incorrect because they do not accurately capture the essence of the psychological contract. While nurse managers may provide positive evaluations, coordinate departments, supervise staff, advocate for staff, and support nursing roles, these actions alone do not define the specific reciprocal nature of the psychological contract outlined in choice C.

3. A client with Addison's disease is experiencing an Addisonian crisis. The nurse should expect to administer which of the following medication?

• A. Insulin
• B. Hydrocortisone
• C. Levothyroxine
• D. Methimazole

Correct answer: B

Rationale: During an Addisonian crisis, the adrenal glands are not producing enough cortisol, leading to a life-threatening situation. Hydrocortisone, a glucocorticoid, is the medication of choice in managing an Addisonian crisis. It helps replace deficient cortisol levels, stabilize blood pressure, and prevent further complications. Insulin (Choice A) is not indicated in Addison's disease unless specifically needed for diabetes management. Levothyroxine (Choice C) is used in hypothyroidism, not in Addison's disease. Methimazole (Choice D) is used to manage hyperthyroidism, which is not related to Addison's disease or its crisis.

4. A client with Graves' disease is prescribed propranolol. The nurse understands that the purpose of this medication is to:

• A. Treat the underlying cause of the disease
• B. Reduce thyroid hormone production
• C. Alleviate symptoms such as tachycardia and tremors
• D. Increase energy levels

Correct answer: C

Rationale: The correct answer is C: Alleviate symptoms such as tachycardia and tremors. Propranolol is a beta-blocker that helps manage symptoms like tachycardia (fast heart rate) and tremors in patients with Graves' disease. Choice A is incorrect because propranolol does not address the underlying cause of Graves' disease, which is autoimmune in nature. Choice B is incorrect because propranolol does not directly reduce thyroid hormone production; it mainly targets the symptoms. Choice D is incorrect because while propranolol may help with symptoms like tachycardia, it is not intended to increase energy levels.

5. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.
