The nurse is administering medications through a nasogastric tube (NGT) which is connected to suction.
After ensuring correct tube placement, what action should the nurse take next?
A. Clamp the tube for 20 minutes.
B. Flush the tube with water.
C. Administer the medications as prescribed.
D. Crush the tablets and dissolve in sterile water. - The NGT should be flushed before, after and in
between each medication administered (B). Once all medications are administered, the NGT should be
clamped for 20 minutes (A). (C and D) may be implemented only after the tubing has been flushed.
Correct Answer: B
What is the most important reason for starting intravenous infusions in the upper extremities rather
than the lower extremities of adults?
A. It is more difficult to find a superficial vein in the feet and ankles.
B. A decreased flow rate could result in the formation of a thrombosis.
C. A cannulated extremity is more difficult to move when the leg or foot is used.
D. Veins are located deep in the feet and ankles, resulting in a more painful procedure. - Venous return
is usually better in the upper extremities. Cannulation of the veins in the lower extremities increases the
risk of thrombus formation (B) which, if dislodged, could be life-threatening. Superficial veins are often
very easy (A) to find in the feet and legs. Handling a leg or foot with an IV (C) is probably not any more
difficult than handling an arm or hand. Even if the nurse did believe moving a cannulated leg was more
difficult, this is not the most important reason for using the upper extremities. Pain (D) is not a
consideration.
Correct Answer: B
A client is to receive cimetidine (Tagamet) 300 mg q6h IVPB. The preparation arrives from the pharmacy
diluted in 50 ml of 0.9% NaCl. The nurse plans to administer the IVPB dose over 20 minutes. For how
many ml/hr should the infusion pump be set to deliver the secondary infusion? - The infusion rate is
calculated as a ratio proportion problem, i.e., 50 ml/ 20 min : x ml/ 60 min. Multiply extremes and
means 50 × 60 /20x
