Nursing Elites

1. A nursing student needs to administer potassium chloride intravenously as prescribed to a client with hypokalemia. The nursing instructor determines that the student is unprepared for this procedure if the student states that which of the following is part of the plan for preparation and administration of the potassium?

• A. Obtaining a controlled IV infusion pump
• B. Monitoring urine output during administration
• C. Diluting an appropriate amount of normal saline
• D. Preparing the medication for bolus administration

Correct answer: D

Rationale: The correct answer is preparing the medication for bolus administration (Choice D). Potassium should never be administered as a bolus because it can cause cardiac arrest. It must always be diluted and given slowly. Obtaining a controlled IV infusion pump (Choice A) is essential for accurate delivery, monitoring urine output during administration (Choice B) helps assess the client's response, and diluting an appropriate amount of normal saline (Choice C) is necessary to prevent irritation and ensure safe administration.

2. 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.

3. Why is it important to control blood glucose levels in type 2 DM?

• A. Hypertension and kidney disease.
• B. Weight gain and obesity.
• C. Improved wound healing.
• D. Decreased cholesterol levels.

Correct answer: A

Rationale: Controlling blood glucose levels in type 2 DM is crucial to prevent complications. High blood glucose levels can lead to hypertension and kidney disease, as seen in diabetic nephropathy and diabetic nephropathy. These are common complications of uncontrolled diabetes. Weight gain and obesity (choice B) are influenced by factors such as diet and physical activity rather than blood glucose levels. Improved wound healing (choice C) is not directly related to blood glucose control but can be affected by it indirectly. Decreased cholesterol levels (choice D) are not a direct consequence of high blood glucose levels and are more related to dietary and lifestyle factors.

4. An agitated, confused female client arrives in the emergency department. Her history includes type 1 diabetes mellitus, hypertension, and angina pectoris. Assessment reveals pallor, diaphoresis, headache, and intense hunger. A stat blood glucose sample measures 42 mg/dl, and the client is treated for an acute hypoglycemic reaction. After recovery, the nurse teaches the client to treat hypoglycemia by ingesting:

• A. 2 to 5 g of a simple carbohydrate.
• B. 10 to 15 g of a simple carbohydrate.
• C. 18 to 20 g of a simple carbohydrate.
• D. 25 to 30 g of a simple carbohydrate.

Correct answer: B

Rationale: The correct answer is B: 10 to 15 g of a simple carbohydrate. In the treatment of hypoglycemia, it is important to administer a specific amount of simple carbohydrates to raise blood glucose levels effectively without causing hyperglycemia. 10 to 15 g of simple carbohydrates, such as glucose tablets, fruit juice, or regular soft drinks, is recommended to rapidly increase blood sugar levels in clients experiencing hypoglycemia. Choices A, C, and D are incorrect as they either provide too little or too much glucose, which may not effectively treat the hypoglycemic episode or may lead to rebound hyperglycemia.

5. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.
