A client is currently receiving an infusion labeled Heparin Sodium 25,000 Units in 5% Dextrose Injection 500 mL at 14 ml/hour. A prescription is received to change the rate of the Infusion to 900 units of heparin per hour. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["18"]
First, we need to find the concentration of Heparin per milliliter in the current infusion. We can do this by dividing the total number of Heparin units by the total volume of the infusion:
Heparin concentration (units/mL) = Total Heparin units / Total volume (mL) Heparin concentration = 25,000 units / 500 mL
Heparin concentration = 50 units/mL
Now, we know the desired rate of Heparin delivery (900 units/hour) and the concentration of Heparin per milliliter (50 units/mL). We can use this information to calculate the required flow rate in milliliters per hour:
Flow rate (mL/hour) = Desired Heparin rate (units/hour) / Heparin concentration (units/mL)
Flow rate = 900 units/hour / 50 units/mL Flow rate = 18 mL/hour
Therefore, the nurse should set the infusion pump to deliver 18 mL/hour.

Correct Answer is ["A","B","C","E"]
Explanation
A. Ask if the client is experiencing any pain with urination. Urinary tract infections (UTIs) are common in older adults and can lead to sudden changes in behavior, including confusion and agitation.
B. Determine if the client has recently experienced a fall. Falls can lead to head injuries or other trauma that may cause confusion or changes in behavior in older adults.
C. Provide instruction on taking the client's temperature. Fever can be a sign of infection, which might be causing the sudden behavioral changes. Monitoring temperature can help identify if an infection is present.
D. Encourage increased intake of high protein foods. While good nutrition is important, it is not directly related to the sudden onset of confusion and agitation, making this a less immediate priority.
E. Review the client's current food and medication allergies. Allergic reactions to foods or
medications can cause sudden behavioral changes. Reviewing allergies can help determine if this is the cause of the symptoms.
Correct Answer is C
Explanation
A. For the next 24 hours, notify the nurse when the bladder is full, and the nurse will collect
catheterized specimens: This instruction is incorrect for a 24-hour urine collection. Catheterized specimens are not typically used for creatinine clearance tests, and the nurse should not be notified when the bladder is full.
B. Urinate immediately into a urinal, and the lab will collect the specimen every 6 hours for the next 24 hours: This instruction is incorrect for a 24-hour urine collection. Creatinine clearance
tests require collection of all urine produced over a 24-hour period, not just specimens at specific intervals.
C. Urinate at a specified time, discard this urine, and collect all subsequent urine during the next 24 hours: This is the correct instruction for a 24-hour urine collection. The client should begin by discarding the first voided urine and then collect all subsequent urine produced over the next 24 hours, including the urine from the specified time.
D. Cleanse around the meatus, discard the first portion of voiding, and collect the rest in a sterile bottle: This instruction is not appropriate for a 24-hour urine collection. It describes a procedure for collecting a clean-catch urine sample, which is different from a 24-hour urine collection for creatinine clearance.
