Nursing Elites

1. A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?

• A. U waves
• B. Absent P waves
• C. Elevated T waves
• D. Elevated ST segment

Correct answer: A

Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.

2. After undergoing a subtotal thyroidectomy, a female client develops hypothyroidism. Dr. Smith prescribes levothyroxine (Levothroid), 25 mcg P.O. daily. For which condition is levothyroxine the preferred agent?

• A. Primary hypothyroidism
• B. Graves' disease
• C. Thyrotoxicosis
• D. Euthyroidism

Correct answer: A

Rationale: Levothyroxine is the preferred agent for primary hypothyroidism because it provides the necessary replacement of thyroid hormone in patients with deficient thyroid function. Choice B, Graves' disease, is an autoimmune disorder that causes hyperthyroidism and is typically treated with antithyroid medications or radioactive iodine. Choice C, thyrotoxicosis, refers to the clinical state resulting from excessive thyroid hormone action and is not typically treated with levothyroxine. Choice D, euthyroidism, describes a normal thyroid function and would not require treatment with levothyroxine.

3. What is the nurse's responsibility when dealing with an impaired colleague?

• A. The nurse should report the colleague to a supervisor and follow the institution's policy for addressing impaired practice.
• B. The nurse should confront the colleague directly and offer support to seek help for the impairment.
• C. Nonmaleficence
• D. The nurse should ignore the colleague's behavior and focus on their own responsibilities.

Correct answer: A

Rationale: When a nurse encounters an impaired colleague, the appropriate action is to report the behavior to a supervisor and follow the institution's policy for addressing impaired practice. This ensures patient safety and upholds professional standards. Choice B is incorrect because confronting the colleague directly may not be appropriate or effective in addressing the issue, and the colleague may need more structured assistance. Choice C is a principle of ethical practice but does not directly address the specific situation of dealing with an impaired colleague. Choice D is incorrect because ignoring the colleague's behavior could potentially compromise patient safety and is not in line with professional responsibility.

4. A client with type 2 diabetes mellitus is being educated on foot care. Which of the following instructions should the nurse provide?

• A. Soak your feet in warm water daily.
• B. Avoid going barefoot to protect your feet.
• C. Inspect your feet daily for any cuts or sores.
• D. Avoid using a heating pad to warm your feet if they are cold.

Correct answer: C

Rationale: The correct instruction for a client with type 2 diabetes mellitus regarding foot care is to inspect their feet daily for any cuts or sores. This practice helps in early detection of potential issues like cuts, sores, or infections, which can be challenging to heal due to poor circulation in diabetes. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage, especially for individuals with diabetes who may have reduced sensation. Choice B is incorrect because going barefoot increases the risk of injuries and infections for individuals with diabetes. Choice D is incorrect because using a heating pad can also impair sensation, increasing the risk of burns or injuries for diabetic individuals.

5. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?

• A. Decreased blood glucose levels
• B. Decreased urine ketones
• C. Increased serum bicarbonate
• D. Increased anion gap

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.
