A nurse is preparing to administer cimetidine 300 mg IV over 15 min to a client. Available is cimetidine 300 mg/100 mL of 0.9% sodium chloride. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Done use a trailing zero.)

Answer and Explanation

The Correct Answer is ["400"]

Step 1: Determine the Total Volume Needed

Supplied concentration: 300 mg/100 mL
Prescribed dose: 300 mg
Total volume needed = 100 mL

Step 2: Convert Time to Hours

Prescribed infusion time = 15 minutes
15 minutes ÷ 60 minutes/hour = 0.25 hours

Step 3: Calculate the Infusion Rate (mL/hr)

Infusion rate = Total volume (mL) ÷ Time (hours)
Infusion rate = 100 mL ÷ 0.25 hours
Infusion rate = 400 mL/hr

The nurse should set the IV pump to deliver cimetidine at 400 mL/hr (rounded to the nearest whole number).

Correct Answer is D

Explanation

A. Administer more than one pill to the client at a time: Administering more than one pill at a time may increase the risk of choking, especially for individuals with dysphagia. It's generally advisable to administer one medication at a time to ensure proper swallowing.
B. Tilt the client's head back when administering the medications: Tipping the head backward can increase the risk of aspiration (inhalation of medication into the airways). It is recommended to keep the head in a neutral or slightly forward position to facilitate swallowing.
C. Place the medications on the back of the client's tongue: Placing medications on the back of the tongue may trigger the gag reflex and increase the risk of aspiration. Medications should be placed on the front of the tongue to allow for better control and coordination of swallowing.
D. Mix the medications with a semisolid food for the client (Correct Answer): Mixing medications with a semisolid food, often referred to as "food thickening," can be beneficial for clients with dysphagia. This helps make the medications easier to swallow and reduces the risk of choking or aspiration. However, it is important to check with the healthcare provider or pharmacist to ensure compatibility with specific medications.

A. A vein that feels hard to the touch B. A vein in the client's dominant arm C. A vein proximal to the previous site D. A vein on the client's wrist

Correct Answer is C

Explanation

A. A vein that feels hard to the touch:
A vein that feels hard to the touch may indicate thrombosis or inflammation and is not a suitable site for catheter insertion.
B. A vein in the client's dominant arm:
The choice of arm may depend on the client's preference, but it is not a strict rule. The nurse can choose a suitable vein in either arm based on factors such as accessibility and vein condition.
C. A vein proximal to the previous site:
This is the correct answer. Placing the catheter proximal (above or upstream) to the previous site helps minimize the risk of complications such as infiltration and thrombophlebitis at the new site. It allows for optimal vein health and reduces the likelihood of complications associated with repeated punctures in the same area.
D. A vein on the client's wrist:
Veins on the wrist may be smaller and more prone to complications. It is generally recommended to choose larger, more accessible veins for catheter insertion.
