The provider orders fluid replacement for a dehydrated patient.

The order entered is 1000 mL over 10 hours.

If using an IV pump, what is the rate that the nurse should enter?

A.

100 mL/hr

B.

200 mL/hr

C.

50 mL/hr

D.

150 mL/hr

E.

150 mL/hr

Answer and Explanation

The Correct Answer is A

Step 1 is to calculate the rate of fluid replacement. The formula for this is: Rate (mL/hr) = Total volume (mL) ÷ Time (hr) So, for this question: Rate (mL/hr) = 1000 mL ÷ 10 hr = 100 mL/hr.

Correct Answer is C

Explanation

Choice A rationale
While the thickness of the tympanic membranes can indeed change with age, it typically increases rather than decreases. Thickening of the tympanic membranes can contribute to hearing loss by reducing the ability of the ear to transmit sound vibrations.
Choice B rationale
Tinnitus, or ringing in the ears, is not typically decreased in older adults. In fact, tinnitus is often more common in older individuals and can be a sign of age-related hearing loss.
Choice C rationale
A decreased ability to hear high-frequency sounds is a common physiological change associated with aging. This is often one of the first signs of age-related hearing loss.
Choice D rationale
Decreased ear wax is not typically associated with aging. In fact, some older adults may produce more ear wax, which can contribute to hearing problems if it becomes impacted.

Correct Answer is B

Explanation

Choice A rationale
While tremors and decreased mobility are common symptoms of Parkinson’s disease, they are not the most significant impact on a patient’s life. These physical symptoms can be managed with medication and physical therapy.
Choice B rationale
Loss of independence is often the most significant impact on a patient’s life. As the disease progresses, patients may find it increasingly difficult to perform daily activities and may require assistance.
Choice C rationale
Age-related changes can contribute to the progression of Parkinson’s disease, but they are not the most significant impact on a patient’s life. The disease itself, rather than aging, is the primary cause of the symptoms.
Choice D rationale
Neurologic deficits are a result of Parkinson’s disease, but they are not the most significant impact on a patient’s life. The loss of independence that results from these deficits is often more impactful.
