Nursing Elites

1. A nurse is preparing to administer insulin to a client with DM. The nurse understands that the peak time for rapid-acting insulin, such as lispro (Humalog), is:

• A. 30 minutes to 1 hour after administration.
• B. 1 to 2 hours after administration.
• C. 2 to 4 hours after administration.
• D. 3 to 5 hours after administration.

Correct answer: A

Rationale: The correct answer is A: 30 minutes to 1 hour after administration. Rapid-acting insulins like lispro, such as Humalog, peak quickly within 30 minutes to 1 hour after administration. This peak time is crucial to monitor for potential hypoglycemia, which is most likely to occur during this period. Choice B is incorrect as it suggests a longer peak time for rapid-acting insulin, which is inaccurate. Choices C and D are also incorrect because they indicate even longer peak times, which do not align with the rapid onset and peak action of lispro insulin.

2. A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:

• A. Increase thyroid hormone production
• B. Decrease thyroid hormone production
• C. Relieve symptoms such as tachycardia and anxiety
• D. Prevent weight loss

Correct answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

3. 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.

4. Clinical nursing assessment for a patient with microangiopathy who has manifested impaired peripheral arterial circulation includes all of the following except:

• A. Integumentary inspection for the presence of brown spots on the lower extremities.
• B. Observation for paleness of the lower extremities.
• C. Observation for blanching of the feet after the legs are elevated for 60 seconds.
• D. Palpation for increased pulse volume in the arteries of the lower extremities.

Correct answer: D

Rationale: In a patient with impaired peripheral arterial circulation, clinical nursing assessment should include integumentary inspection for the presence of brown spots, observation for paleness of the lower extremities, and observation for blanching of the feet after the legs are elevated for 60 seconds. Palpation for increased pulse volume in the arteries of the lower extremities is not consistent with impaired circulation, as pulses are typically diminished in this condition. Therefore, palpation for increased pulse volume is not relevant to the assessment of impaired peripheral arterial circulation.

5. 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.
