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 traits is characteristic of a caring leader?

• A. A caring leader serves first and leads second.
• B. A caring leader is aware of the feelings of others.
• C. The traits of a caring leader include respecting coworkers as individuals and empathizing with the needs and concerns of others.
• D. A caring leader is fair and honest.

Correct answer: C

Rationale: A caring leader is characterized by respecting coworkers as individuals and empathizing with their needs and concerns. Choice A is more about servant leadership rather than specifically about caring leadership. Choice B, while related to empathy, does not encompass the full spectrum of traits associated with a caring leader. Choice D, being fair and honest, is important in leadership but does not solely define a caring leader.

3. For a male client with hyperglycemia, which assessment finding best supports a nursing diagnosis of Deficient fluid volume?

• A. Cool, clammy skin
• B. Distended neck veins
• C. Increased urine osmolarity
• D. Decreased serum sodium level

Correct answer: C

Rationale: Increased urine osmolarity is the best assessment finding supporting a nursing diagnosis of Deficient fluid volume in a male client with hyperglycemia. In hyperglycemia, there is increased glucose in the blood, which leads to osmotic diuresis. This results in the excretion of large amounts of urine that is concentrated (high osmolarity), leading to dehydration and fluid volume deficit. Cool, clammy skin (Choice A) is more indicative of poor perfusion, distended neck veins (Choice B) are associated with fluid volume excess, and decreased serum sodium level (Choice D) could be a result of dilutional hyponatremia due to fluid overload rather than deficient fluid volume.

4. A healthcare professional is preparing to care for a client with a potassium deficit. The healthcare professional reviews the client's record and determines that the client was at risk for developing the potassium deficit because the client:

• A. Has renal failure.
• B. Requires nasogastric suction.
• C. Has a history of Addison's disease.
• D. Is taking a potassium-sparing diuretic.

Correct answer: B

Rationale: Nasogastric suction can lead to significant potassium loss due to the continuous drainage of gastric contents, increasing the risk of a potassium deficit. Choices A, C, and D do not directly result in the significant loss of potassium. Renal failure may lead to potassium retention rather than a deficit. Addison's disease is associated with adrenal insufficiency, not potassium depletion. Potassium-sparing diuretics, as the name suggests, typically help retain potassium rather than cause a deficit.

5. What clinical feature distinguishes a hypoglycemic reaction from a ketoacidosis reaction?

• A. Blurred vision.
• B. Diaphoresis.
• C. Nausea.
• D. Weakness.

Correct answer: B

Rationale: Diaphoresis is the correct answer because it is more characteristic of hypoglycemia. Hypoglycemia typically presents with symptoms such as diaphoresis (excessive sweating), palpitations, tremors, and anxiety. On the other hand, ketoacidosis is associated with symptoms such as fruity breath, deep and labored breathing (Kussmaul respirations), nausea, vomiting, and abdominal pain. Blurred vision can occur in both hypoglycemia and ketoacidosis due to metabolic disturbances affecting the eyes. Weakness is a nonspecific symptom that can be present in both conditions, making it less helpful in distinguishing between the two.
