A client is being educated about insulin and is able to repeat the newly acquired information using their own words to the nurse.
Which of the following statements confirm the teaching has been effective?
I should have my hemoglobin A1C checked monthly.
I should always have my breakfast ready to eat before injecting my morning insulin.
If I feel hungry I can eat early and take a little extra insulin next time it is due.
On sick days I don’t have to check my blood sugar or eat, just get plenty of fluids.
The Correct Answer is B
I should always have my breakfast ready to eat before injecting my morning insulin. This statement confirms that the client understands the importance of matching insulin administration with food intake to prevent hypoglycemia.
Choice A is wrong because hemoglobin A1C should be checked every 3 months, not monthly, to monitor long-term glycemic control.
Choice C is wrong because eating early and taking extra insulin later can cause fluctuations in blood glucose levels and increase the risk of complications.
Choice D is wrong because on sick days, the client should check blood sugar more
often and eat small amounts of carbohydrates to prevent hyperglycemia and ketoacidosis.

Correct Answer is B
Explanation
Pulse oximetry works by measuring the amount of light that passes through your finger and reaches a sensor on the other side.
The amount of light that is absorbed by your blood depends on how much oxygen it carries. Nail polish can block or reflect some of the light, making it harder for the pulse oximeter to get an accurate reading of your oxygen level.
Choice A is wrong because the color of your nailbed is not relevant for pulse oximetry.
The pulse oximeter does not measure the color of your nailbed, but the amount of light that passes through it.
Choice C is wrong because the sensor does not react with the nail polish causing an allergic reaction.
The sensor is a non-invasive device that does not touch your skin or nail polish directly.
Choice D is wrong because the chemicals in the nail polish do not cause falsely decreased readings of your oxygen level.
The chemicals in the nail polish do not affect the amount of oxygen in your blood, but only the amount of light that reaches the sensor.
Normal ranges for pulse oximetry vary depending on your health condition and altitude, but generally they are between 95% and 100%. If your pulse oximetry reading is lower than 90%, you may have hypoxia, which means your tissues are not getting enough oxygen.
Correct Answer is B
Explanation
To explain why, we need to use the formula for calculating the drip rate in drops per minute (dpm):
Volume of IV fluid (mL) x Drop Factor (drops/mL) / Time to run (h) x 60 (min/h) = Drip Rate (dpm)
In this question, the volume of IV fluid is one liter, which is equivalent to 1000 mL. The drop factor is 15 drops per mL, as given by the tubing.
The time to run is six hours, as ordered by the physician. Plugging these values into the formula, we get:
1000 mL x 15 drops/mL / 6 h x 60 min/h = 84 dpm
Therefore, the nurse should regulate the infusion to deliver 84 drops per minute.
Choice A is wrong because it gives a drip rate of 42 drops per minute, which is half of the correct answer.
This would result in delivering only 500 mL of normal saline in six hours, instead of one liter.
Choice C is wrong because it gives a drip rate of 100 drops per minute, which is more than the correct answer.
This would result in delivering 1.43 liters of normal saline in six hours, instead of one liter.
Choice D is wrong because it gives a drip rate of 166 drops per minute, which is almost double the correct answer.
This would result in delivering 1.99 liters of normal saline in six hours, instead of one liter.
Normal saline is a solution of 0.9% sodium chloride in water, which has the same osmolarity as blood plasma.
It is used to treat dehydration, shock, blood loss, and other conditions that require fluid replacement.
The normal range of sodium in blood is 135-145 mEq/L.
