Nursing Elites

1. How often should rotation sites for insulin injection be separated from one another?

• A. Every third day.
• B. Every week.
• C. Every 2-3 weeks.
• D. Every 2-4 weeks.

Correct answer: C

Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.

2. The healthcare provider is assessing a client with suspected syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory findings is most consistent with this condition?

• A. Increased serum sodium
• B. Decreased urine specific gravity
• C. Decreased serum osmolality
• D. Increased serum potassium

Correct answer: C

Rationale: The correct answer is C: Decreased serum osmolality. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. The dilution of sodium results in decreased serum osmolality. Option A is incorrect because SIADH causes hyponatremia, resulting in decreased serum sodium levels. Option B is incorrect because SIADH leads to concentrated urine with increased urine specific gravity. Option D is incorrect as SIADH does not typically affect serum potassium levels.

3. 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.

4. A client with a nasogastric tube requires irrigation once every shift. The client's serum electrolyte results show a potassium level of 4.5 mEq/L and a sodium level of 132 mEq/L. Based on these findings, which solution should the nurse use for nasogastric tube irrigation?

• A. Tap water
• B. Sterile water
• C. Sodium chloride
• D. Normal saline

Correct answer: C

Rationale: The correct solution for nasogastric tube irrigation in this scenario is sodium chloride. The client's low sodium level of 132 mEq/L indicates the need to avoid further imbalance, making sodium chloride the most appropriate choice. Using tap water, which lacks electrolytes, or sterile water could potentially exacerbate the electrolyte imbalance. Normal saline, while similar to sodium chloride, may not be the best choice as it contains a higher concentration of sodium, which could further elevate the client's already borderline sodium level.

5. Albert, a 35-year-old insulin-dependent diabetic, is admitted to the hospital with a diagnosis of pneumonia. He has been febrile since admission. His daily insulin requirement is 24 units of NPH. Every morning Albert is given NPH insulin at 0730. Meals are served at 0830, 1230, and 1830. The nurse expects that the NPH insulin will reach its maximum effect (peak) between the hours of:

• A. 1130 and 1330.
• B. 1330 and 1930.
• C. 1530 and 2130.
• D. 1730 and 2330.

Correct answer: C

Rationale: NPH insulin typically peaks 4-12 hours after administration, so a peak between 1530 and 2130 would be expected. Choice A (1130 and 1330) is too early for the peak effect of NPH insulin. Choice B (1330 and 1930) falls within the possible peak period but is not as accurate as choice C. Choice D (1730 and 2330) is too late for the peak effect of NPH insulin based on the typical peak timing.
