Answer and Explanation

The Correct Answer is ["31"]

Step 1: Calculate the total infusion time in minutes.

8 hours × 60 minutes/hour = 480 minutes

Result at each step = 480 minutes

Step 2: Calculate the total number of drops to be infused.

1,000 mL × 15 drops/mL = 15,000 drops

Result at each step = 15,000 drops

Step 3: Calculate the infusion rate in drops per minute.

15,000 drops ÷ 480 minutes = 31.25 drops/minute

Result at each step = 31.25 drops/minute

Step 4: Round to the nearest whole number if necessary.

31.25 drops/minute rounds to 31 drops/minute

Result at each step = 31 drops/minute

Therefore, the nurse should run the IV infusion at a rate of 31 drops per minute.

Correct Answer is ["B"]

Explanation

Choice A Reason: High-flow nasal cannula

The high-flow nasal cannula (HFNC) is designed to deliver oxygen at flow rates much higher than 5 liters per minute, typically ranging from 20 to 60 liters per minute. It is used for patients requiring high levels of oxygen and positive airway pressure. Therefore, it is not appropriate for a flow rate of 5 liters per minute.

Choice B Reason: Simple face mask

The simple face mask is suitable for delivering oxygen at flow rates between 6 to 10 liters per minute. However, it can also be used at a flow rate of 5 liters per minute, providing an FiO2 (fraction of inspired oxygen) of approximately 40-60%. This makes it an appropriate choice for the given requirement.

Choice C Reason: Nasal cannula

The nasal cannula is a low-flow oxygen delivery device that can deliver oxygen at flow rates from 1 to 6 liters per minute. At 5 liters per minute, it provides an FiO2 of approximately 40%. It is comfortable for patients and is commonly used for those who need a moderate amount of supplemental oxygen.

Choice D Reason: Non-rebreather mask

The non-rebreather mask is designed to deliver high concentrations of oxygen, typically at flow rates of 10 to 15 liters per minute. It is used in situations where patients need a high FiO2, close to 100%. Therefore, it is not suitable for a flow rate of 5 liters per minute.

Choice E Reason: Venturi mask

The Venturi mask is used to deliver precise oxygen concentrations, typically ranging from 24% to 60% FiO2. It is suitable for patients who require controlled oxygen therapy. While it can be adjusted to deliver oxygen at a flow rate of 5 liters per minute, it is generally used for more specific FiO2 requirements.

A. I sleep at least 8 hours each night. B. I cannot seem to quench my thirst. C. I have to void nearly every hour. D. At times my vision is blurry. E. I have lost 10 pounds without even trying.

Correct Answer is ["B","C","D","E"]

Explanation

Choice A Reason:

I sleep at least 8 hours each night.

This statement is not concerning because getting adequate sleep is generally a sign of good health. It does not directly relate to symptoms of high blood glucose levels. Therefore, this choice is not relevant to the nurse’s concerns regarding the client’s elevated blood glucose level.

Choice B Reason:

I cannot seem to quench my thirst.

This statement is concerning because excessive thirst, known as polydipsia, is a common symptom of high blood glucose levels or hyperglycemia. When blood glucose levels are elevated, the body tries to eliminate the excess glucose through urine, leading to dehydration and increased thirst. This symptom indicates that the client’s blood glucose levels may be poorly controlled, which requires medical attention.

Choice C Reason:

I have to void nearly every hour.

Frequent urination, or polyuria, is another symptom of high blood glucose levels. When there is too much glucose in the blood, the kidneys work harder to filter and absorb it. When they can’t keep up, the excess glucose is excreted into the urine, pulling fluids from the tissues and causing frequent urination. This symptom is a clear indicator of hyperglycemia and needs to be addressed by the nurse.

Choice D Reason:

At times my vision is blurry.

Blurred vision can be a symptom of high blood glucose levels. Elevated glucose levels can cause the lens of the eye to swell, leading to changes in vision. This symptom is concerning because it suggests that the client’s blood glucose levels are affecting their vision, which can be a sign of poorly managed diabetes or other complications.

Choice E Reason:

I have lost 10 pounds without even trying.

Unintentional weight loss is a concerning symptom of high blood glucose levels. When the body cannot use glucose for energy due to insulin resistance or lack of insulin, it starts to break down muscle and fat for energy, leading to weight loss. This symptom indicates that the client’s diabetes may be uncontrolled, and immediate medical intervention is necessary.
