A nurse is caring for a client who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 mL DSW. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["24"]

To calculate the infusion rate, use the formula:

(rate in mL/hr) = (desired dose in units/hr) / (available dose in units/mL)

In this case, the desired dose is 1,200 units/hr and the available dose is 25,000 units / 500 mL = 50 units/mL. Therefore,

(rate in mL/hr) = (1,200 units/hr) / (50 units/mL) = 24 mL/hr

Round the answer to the nearest tenth/whole number and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.

Correct Answer is A

Explanation

A. The radial pulse in the left arm can be palpated after a cardiac catheterization with a left antecubital insertion site. Although the focus is typically on the site of insertion and the brachial pulse, the radial pulse in the left arm can still provide useful information about circulation in that limb.
B. The radial pulse in the right arm is not pertinent because the catheterization was performed on the left side.
C. The brachial pulse in the left arm is indeed important to assess, but palpating the radial pulse in the left arm is also valid to check for circulation.
D. The brachial pulse in the right arm is not relevant in this scenario, as it does not relate to the site of catheterization.

A. Hold the client's arms and legs from moving. B. Place the client back in bed. C. Place the client on his side. D. Insert a tongue blade in the client's mouth.

Correct Answer is C

Explanation

Placing the client on his side is an essential action to take during a seizure, as it can prevent airway obstruction and aspiration. The client should be placed on his side, preferably in a lateral recumbent position, to allow saliva and secretions to drain from the mouth.

Holding the client's arms and legs from moving is not appropriate, as it can cause injury, increase agitation, or prolong the seizure. The client should be allowed to move freely during a seizure, but supported and guided away from hazards.

Placing the client back in bed is not necessary, as it can cause harm or delay care. The client should be left on the ﬂoor, unless it is unsafe or uncomfortable, and padded with pillows or blankets to protect from injury.

Inserting a tongue blade in the client's mouth is not advisable, as it can cause oral trauma, choking, or damage to the teeth. The client should not have anything inserted into his mouth during a seizure, as he cannot swallow or bite his tongue. The nurse should ensure that the client's airway is clear and patent.
