Nursing Elites

1. A client is taking NPH insulin daily every morning. The nurse instructs the client that the most likely time for a hypoglycemic reaction to occur is:

• A. 2-4 hours after administration
• B. 6-14 hours after administration
• C. 16-18 hours after administration
• D. 18-24 hours after administration

Correct answer: B

Rationale: The correct answer is B: 6-14 hours after administration. NPH insulin has an onset of action within 1-2 hours, a peak action at 6-14 hours, and a duration of action of 16-24 hours. The peak action period, which is when the risk of hypoglycemia is highest, falls between 6-14 hours after administration. Choices A, C, and D are incorrect because they do not align with the typical action profile of NPH insulin.

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. Nurse Ruth is assessing a client after a thyroidectomy. The assessment reveals muscle twitching and tingling, along with numbness in the fingers, toes, and mouth area. The nurse should suspect which complication?

• A. Tetany
• B. Hemorrhage
• C. Thyroid storm
• D. Laryngeal nerve damage

Correct answer: A

Rationale: The correct answer is 'Tetany.' Tetany is characterized by muscle twitching, tingling, and numbness, which are indicative of hypocalcemia. After a thyroidectomy, accidental removal or damage to the parathyroid glands can lead to decreased calcium levels, resulting in tetany. Choice B, 'Hemorrhage,' is incorrect as it typically presents with symptoms such as sudden swelling, increased pain, or drop in blood pressure. Choice C, 'Thyroid storm,' is incorrect as it involves a sudden exacerbation of hyperthyroidism, leading to symptoms like fever, tachycardia, and confusion. Choice D, 'Laryngeal nerve damage,' is incorrect as it would manifest with voice changes, difficulty swallowing, or respiratory distress, not the symptoms described in the scenario.

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 refuses his bedtime snack. This should alert the healthcare provider to assess for:

• A. Elevated serum bicarbonate and decreased blood pH.
• B. Signs of hypoglycemia earlier than expected.
• C. Symptoms of hyperglycemia due to NPH insulin peak time.
• D. Presence of sugar in the urine.

Correct answer: B

Rationale: When a patient like Albert refuses his bedtime snack, it can lead to hypoglycemia, especially if they are on medication such as insulin. Hypoglycemia can occur earlier than expected due to the lack of carbohydrate intake before bedtime. This situation warrants the healthcare provider to monitor for signs and symptoms of hypoglycemia. Choice A is incorrect because the given scenario is more indicative of hypoglycemia than metabolic alkalosis. Choice C is incorrect as NPH insulin peak time is not directly related to skipping a bedtime snack. Choice D is incorrect as sugar in the urine typically indicates hyperglycemia, not hypoglycemia.
