Nursing Elites

1. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

2. 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.

3. A client with terminal pancreatic cancer asks questions about a do not resuscitate order. Which of the following statements should be included in the RN's teaching to the client?

• A. When a heart ceases to beat, the client is pronounced clinically dead.
• B. Physicians must write do not resuscitate (DNR) orders.
• C. A DNR order can be written after the healthcare provider has discussed it with the client and family.
• D. A DNR requires a court decision.

Correct answer: C

Rationale: A DNR order is typically written after the healthcare provider has discussed the implications with the patient and their family. This ensures that the patient and family are fully informed before making such a critical decision. Choice A is incorrect because pronouncing clinical death is a medical determination, not directly related to DNR orders. Choice B is incorrect because while physicians commonly write DNR orders, the discussion with the patient and family is crucial. Choice D is incorrect because a DNR order does not require a court decision; it is a decision made in collaboration with the healthcare team and the patient or family.

4. The client has undergone a thyroidectomy. Which of the following symptoms would indicate a potential complication?

• A. Bradycardia
• B. Tachycardia
• C. Hyperreflexia
• D. Hypocalcemia

Correct answer: D

Rationale: Hypocalcemia is a potential complication of thyroidectomy as it may occur if the parathyroid glands, responsible for calcium regulation, are inadvertently removed or damaged during the procedure. Bradycardia (slow heart rate) is not typically associated with thyroidectomy complications. Tachycardia (fast heart rate) is more commonly seen in hyperthyroidism. Hyperreflexia (exaggerated reflex responses) is not a typical complication of thyroidectomy.

5. For the first 72 hours after thyroidectomy surgery, nurse Jamie would assess the female client for Chvostek's sign and Trousseau's sign because they indicate which of the following?

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

Correct answer: A

Rationale: Chvostek's and Trousseau's signs are clinical manifestations that suggest hypocalcemia, a common complication following thyroidectomy. Chvostek's sign is elicited by tapping the facial nerve, resulting in facial muscle contraction, while Trousseau's sign is provoked by inflating a blood pressure cuff, leading to carpal spasm. Both signs are indicative of low calcium levels in the blood. Therefore, options B, C, and D are incorrect as they do not correlate with the signs specifically associated with hypocalcemia.
