Clinical Key Questions

A nurse is gathering supplies to assess an implanted venous access device. Which syringe is the most appropriate to use for that assessment?

10-ml syringe

On first rounds, the nurse observes that the patient has an IV infusion of D5 normal saline running at 125 ml/hr. Later, at 0700, 500 ml remain in the bag. At what time should the IV bag empty?

1100 Rationale: 500 ml ÷ 125 ml/hr = 4 hr; 0700 + 4 hr = 1100.

The patient is to receive 500 ml over 4 hours. The IV tubing available is 10 gtt/ml. Which of the following is the appropriate drip per minute rate?

21 gtt/min Rationale: 500 ml ÷ 4 hr = 125 ml/hr; 125 ml/hr × 10 gtt/min = 1250 gtt/hr; 1250 gtt/hr ÷ 60 gtt/min = 20.833 gtt/min.

When hanging the first of two ordered IV antibiotics for a patient with one IV site, the nurse uses an intermittent administration set and notes that it will need to be changed in how many hours?

24 hours

The practitioner has ordered an IV infusion of 1000 ml over 10 hours. The macrodrip infusion set has a calibration of 15 gtt/ml. Which of the following rates should the nurse use to regulate the macrodrip infusion?

25 gtt/min Rationale: 1000ml ÷ 10 hours = 100 ml/hr; 100 ml/hr × 15 gtt/ml = 1500 gtt/hr; 1500 gtt/hr ÷ 60 min = 25 gtt/min.

A hemolytic transfusion reaction

A nursing student asks the preceptor about when to routinely change an IV solution. Which statement would be an appropriate response to the student?

Which of the following is an appropriate action for the nurse who is preparing to insert an IV catheter in a 9-year-old child?

Allowing the older child to select the IV site helps increase cooperation, letting the child feel some control in the procedure. Veins in the scalp or the foot should be considered with infants, but not older children. Family members should be allowed to stay with the child to help the child cope with the procedure. Venipuncture should be performed in a neutral space to allow the child's room to be a safe place.

Which of the following steps should the nurse include when preparing for IV catheter insertion?

Apply a tourniquet above the selected site.

After placing an IV catheter in a patient's forearm, the nurse should take which action to secure it in place?

If using a gauze dressing, the nurse should tape all edges to minimize IV site contamination. Tape should never be placed on the insertion site because it may introduce contaminants and prevents easy visualization of the site. Wrapping gauze around the arm may prevent visualization of the insertion site and cause constriction. Tape on top of a transparent dressing prevents moisture from being carried away from the skin.

The charge nurse is evaluating a new nurse's ability to insert an IV catheter. Which of the following actions by the new nurse may indicate the need for more education?

The nurse should apply the tourniquet 10 to 15 cm (4 to 6 inches) above the anticipated insertion site and check the presence of the distal pulse. Diminished arterial flow prevents venous filling; the pressure of the tourniquet should be tight enough to cause the vein to dilate, but not so tight that it affects arterial flow. Using the most distal site in the nondominant arm; pressing down and noting a resilient, soft, bouncy feeling as pressure is released; and placing the extremity in a dependent position are all good techniques.
