Nursing Elites

1. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

• A. Prominent U waves
• B. Prolonged PR interval
• C. Depressed ST segment
• D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

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. The nurse is caring for a client with primary adrenal insufficiency (Addison's disease). Which of the following laboratory findings would the nurse expect?

• A. Hypernatremia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hypercalcemia

Correct answer: B

Rationale: In primary adrenal insufficiency (Addison's disease), there is a decrease in aldosterone levels, leading to sodium loss and potassium retention. This imbalance results in hyperkalemia, making choice B the correct answer. Hypernatremia (choice A) is unlikely due to sodium loss. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with primary adrenal insufficiency.

4. During preoperative teaching for a female client undergoing subtotal thyroidectomy, which statement should the nurse include?

• A. The head of your bed must remain flat for 24 hours after surgery.
• B. You should avoid deep breathing and coughing after surgery.
• C. You won't be able to swallow for the first day or two.
• D. You must avoid hyperextending your neck after surgery.

Correct answer: D

Rationale: The correct answer is D. Instructing the client to avoid hyperextending the neck after thyroid surgery is crucial to prevent stress on the surgical site and reduce the risk of complications such as strain on the incision or damage to the healing tissues. Choices A, B, and C are incorrect because: A) Keeping the head of the bed flat for 24 hours is not necessary after a thyroidectomy; elevation of the head of the bed can actually help reduce swelling and improve comfort. B) Encouraging deep breathing and coughing after surgery is essential to prevent respiratory complications such as pneumonia, so this advice is incorrect. C) Difficulty swallowing after thyroid surgery is not a typical outcome, so this statement is inaccurate and should not be included in the preoperative teaching.

5. A client with DM is being taught about the importance of foot care by a nurse. Which instruction should the nurse include?

• A. Use a heating pad to warm your feet.
• B. Avoid walking barefoot.
• C. Soak your feet in hot water every night.
• D. Wear tight shoes to protect your feet.

Correct answer: B

Rationale: The correct instruction for the nurse to include is to advise the client to avoid walking barefoot. This recommendation is crucial for clients with diabetes to prevent foot injuries and infections. Walking barefoot can lead to unnoticed wounds or ulcers due to reduced sensation in the feet (neuropathy) common in diabetes. Choice A is incorrect as heating pads can cause burns and should be avoided. Choice C is incorrect because soaking feet in hot water can also lead to burns and skin damage. Choice D is incorrect as tight shoes can increase the risk of pressure sores and restrict blood flow, which is detrimental for individuals with diabetes.
