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 instruction about insulin administration should Nurse Kate give to a client?

• A. Always follow the same order when drawing up different insulins into the syringe.
• B. Shake the vials before withdrawing the insulin.
• C. Store unopened vials of insulin in the refrigerator at recommended temperatures.
• D. Discard the intermediate-acting insulin if it appears cloudy.

Correct answer: A

Rationale: The correct answer is A. Consistently following the same order when drawing up different insulins helps to prevent medication errors. Option B is incorrect because shaking insulin vials could cause bubbles to form, leading to inaccurate dosing. Option C is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness. Option D is incorrect because cloudy appearance in intermediate-acting insulin may indicate the presence of insulin crystals, which can affect its potency, but this does not necessarily mean it should be discarded without consulting a healthcare provider.

3. A client with type 1 DM is experiencing hypoglycemia. Which symptom should the nurse expect to observe?

• A. Tachycardia
• B. Polyuria
• C. Flushed skin
• D. Dry mouth

Correct answer: A

Rationale: The correct answer is A: Tachycardia. In hypoglycemia, the body releases adrenaline in response to low blood glucose levels, leading to symptoms such as tachycardia (rapid heart rate). Choice B, polyuria, refers to excessive urination and is not a typical symptom of hypoglycemia. Choice C, flushed skin, is not a common symptom of hypoglycemia; instead, pale skin and sweating are more characteristic. Choice D, dry mouth, is not directly associated with hypoglycemia; rather, it can be a symptom of hyperglycemia or dehydration.

4. A good relationship between a leader and a follower enables the follower to 'manage up.' Which of the following describes the best way for a follower to 'manage up'?

• A. Provide feedback to the unit manager when asked for it.
• B. Assist your manager in capitalizing on his or her strengths and weaknesses.
• C. When working with a manager with poor leadership skills, transferring to a different unit is the best option.
• D. Show respect and appreciation for the manager, even when conversing with coworkers.

Correct answer: B

Rationale: The best way for a follower to 'manage up' is by assisting the manager in capitalizing on his or her strengths and weaknesses. By doing so, the follower helps build a good working relationship with the manager, fostering mutual growth and development. Choice A is not the best option as it only focuses on providing feedback when asked, which may not necessarily contribute to 'managing up.' Choice C is incorrect because transferring to a different unit should not be the first solution when dealing with a manager with poor leadership skills; instead, efforts should be made to improve the current working relationship. Choice D, while important, focuses more on showing respect and appreciation rather than actively helping the manager improve, which is key to 'managing up.'

5. A client with type 1 DM calls the nurse to report recurrent episodes of hypoglycemia with exercise. Which statement by the client indicates an inadequate understanding of the peak action of NPH insulin and exercise?

• A. The best time for me to exercise is every afternoon.
• B. The best time for me to exercise is right after I eat.
• C. The best time for me to exercise is after breakfast.
• D. The best time for me to exercise is after my morning snack.

Correct answer: A

Rationale: Exercising in the afternoon may coincide with the peak action of NPH insulin, increasing the risk of hypoglycemia. The peak action of NPH insulin typically occurs 4-12 hours after administration, so exercising during this time can further lower blood sugar levels. Choices B, C, and D are better options as they suggest exercising at times that are less likely to overlap with the peak insulin action, reducing the risk of hypoglycemia.
