A nurse is preparing a 50 mL dose of 50% dextrose IV for a patient experiencing insulin shock. What is the best method for administering the medication?

Mix the dextrose in a 50 mL piggyback for a total volume of 100 mL.

Dilute the dextrose in one liter of 0.9% normal saline solution.

Ask the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution.

Push the undiluted dextrose slowly through the currently infusing IV.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Mixing the dextrose in a 50 mL piggyback for a total volume of 100 mL is not the best method for administering the medication. This would dilute the dextrose, potentially reducing its effectiveness.
Choice B rationale
Diluting the dextrose in one liter of 0.9% normal saline solution is not the best method for administering the medication. This would significantly dilute the dextrose, potentially reducing its effectiveness.
Choice C rationale
Asking the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution is not the best method for administering the medication. This would not provide the immediate glucose boost needed to counteract insulin shock.
Choice D rationale

Pushing the undiluted dextrose slowly through the currently infusing IV is the best method for administering the medication. This allows for rapid administration of a concentrated glucose solution, which is necessary to quickly raise blood glucose levels in a patient experiencing insulin shock.

Correct Answer is C

Explanation

Choice A rationale
Vegetarian lasagna with cheese and spinach, a tossed green salad with ranch dressing, and fresh fruit is a balanced meal. However, it may not be the best choice for a patient with type 2 diabetes due to the high carbohydrate content in the lasagna and the dressing.
Choice B rationale
Fried chicken breast, mashed potatoes, green beans, sliced tomatoes, and fresh apple pie is not the best choice for a patient with type 2 diabetes. Fried foods and mashed potatoes are high in carbohydrates and fats, which can raise blood sugar levels.
Choice C rationale
Grilled fish with whole-grain brown rice, steamed broccoli, and a pear poached in red wine is a good choice for a patient with type 2 diabetes. This meal is balanced with lean protein, whole grains, and vegetables, which can help control blood sugar levels.

Choice D rationale
Lean hamburger with cheese, tomato, and lettuce on a whole-wheat bun, and angel food cake is not the best choice for a patient with type 2 diabetes. Although the hamburger is lean, the whole-wheat bun and angel food cake are high in carbohydrates, which can raise blood sugar levels.

A. Compare muscle strength bilaterally. B. Observe color and amount of urine. C. Determine apical pulse rate and rhythm. D. Assess strength of deep tendon reflexes.

Correct Answer is C

Explanation

Choice A rationale
Comparing muscle strength bilaterally is important in assessing overall physical health and detecting any potential neuromuscular disorders. However, in the context of a client with a history of heart failure and elevated potassium levels, this would not be the most critical intervention. High potassium levels can lead to hyperkalemia, which can cause serious heart rhythm disturbances.
Choice B rationale
Observing the color and amount of urine can provide valuable information about the client’s hydration status and kidney function. In the case of heart failure, monitoring urine output can help assess the effectiveness of diuretic therapy and the progression of the disease. However, it is not the most immediate concern given the client’s high potassium levels.
Choice C rationale

Determining the apical pulse rate and rhythm is the most important intervention in this scenario. A serum potassium level of 6.2 mEq/L is higher than the normal range (3.5-5.0 mEq/L) and can cause life-threatening heart rhythm abnormalities. Therefore, the nurse should prioritize assessing the client’s heart rhythm to detect any abnormalities caused by this electrolyte imbalance.
Choice D rationale
Assessing the strength of deep tendon reflexes can help identify changes in neuromuscular function and is often used in neurological assessments. However, it is not the most critical intervention in the context of elevated potassium levels and heart failure.
