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 role in patient education?

• A. The nurse is responsible for providing patients with information they need to make informed decisions about their care.
• B. The nurse provides education to the patient and their family to help them understand the care plan and make informed decisions.
• C. The nurse is responsible for providing patients with written materials to help them understand their condition and treatment options.
• D. The nurse provides patients with verbal and written instructions on how to manage their care at home.

Correct answer: A

Rationale: The correct answer is A. The nurse's role in patient education involves providing patients with the necessary information to make informed decisions about their care. This includes explaining treatment options, potential risks and benefits, and answering any questions the patient may have. Choice B is incorrect because while nurses do educate patients and families, the primary focus is on empowering patients to make informed decisions. Choice C is incorrect as providing written materials is a part of patient education but not the sole responsibility of the nurse. Choice D is incorrect because while nurses do provide instructions on managing care at home, patient education goes beyond just the home care aspect to encompass a broader understanding of the patient's condition and treatment.

3. A client with DM asks a nurse why it is necessary to rotate injection sites when using an insulin pen. The nurse's best response would be:

• A. To prevent scar tissue from forming under the skin.
• B. To make the injections less painful.
• C. To help the insulin absorb better.
• D. To keep the skin looking healthy.

Correct answer: C

Rationale: The correct answer is C: "To help the insulin absorb better." Rotating injection sites is important as it helps to ensure better insulin absorption and reduces the risk of developing lipodystrophy. Option A is incorrect as rotating sites primarily aims to optimize insulin absorption, not prevent scar tissue. Option B is inaccurate because rotating injection sites does not necessarily make the injections less painful. Option D is incorrect as the primary reason for rotating injection sites is not related to the aesthetics of the skin but rather to enhance insulin absorption and prevent complications.

4. A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:

• A. Obtain a new vial of NPH insulin.
• B. Draw up the cloudy insulin as ordered.
• C. Shake the vial vigorously before drawing up the insulin.
• D. Warm the insulin to room temperature before administration.

Correct answer: B

Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.

5. The client has been diagnosed with primary aldosteronism. Which of the following clinical findings would the nurse expect?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: B

Rationale: Primary aldosteronism involves the overproduction of aldosterone by the adrenal glands. Aldosterone increases potassium excretion, leading to hypokalemia. Therefore, in primary aldosteronism, the nurse would expect to find hypokalemia, not hyperkalemia (choice A), hyponatremia (choice C), or hypercalcemia (choice D).
