NurseDive Free Nursing Practice Question
A nurse is preparing to administer lactated Ringer's 1,500 mL IV to infuse at 50 mL/hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Full Explanation
gtt/min = (mL/hr x gtt/mL) / 60
gtt/min = (50 x 15) / 60 gtt/min = 750 / 60 gtt/min = 12.5 Rounding to the nearest whole number, the answer is 13.
Therefore, the nurse should set the manual IV infusion to deliver 13 gtt/min.
Similar Questions
A nurse is assessing for correct placement of a client's NG feeding tube prior to administering a bolus feeding.
Which of the following actions should the nurse take?
A. Insert air in the tube and listen for gurgling sounds in the epigastric area
Inserting air in the tube and listening for gurgling sounds in the epigastric area is not a reliable method to confirm NG tube placement, as it can produce falsepositive results due to air entering the stomach or intestines.
B. Aspirate contents from the tube and verify the pH level
Aspirating contents from the tube and verifying the pH level is a valid method to confirm NG tube placement, as gastric contents typically have a pH of less than5.5, while intestinal or respiratory contents have a higher pH.
C. Review the medical record for previous x-ray verification of placement
Reviewing the medical record for previous x-ray verification of placement is not sufficient to confirm NG tube placement, as the tube can migrate or become dislodged after insertion. X-ray verification should be done initially and whenever there is doubt about the tube's position.
D. Auscultate the lungs for adventitious breath sounds
Auscultating the lungs for adventitious breath sounds is not a specific method to confirm NG tube placement, as it can indicate other conditions such as pneumonia or pulmonary edema. It can also miss signs of respiratory complications due to NG tube misplacement, such as pneumothorax or bronchial obstruction.

A school nurse is notified of an emergency in which several children were injured following the collapse of playground equipment. Upon arrival at the playground, which of the following actions should the nurse take first?
A. Instruct a staff member to maintain a log of emergency care provided.
Instructing a staff member to maintain a log of emergency care provided is not the first action that the nurse should take. This is an important task, but it can be done later, after ensuring the safety of the staff and children and providing immediate care to those who need it.
B. Apply cervical spine collars to children who have suspected neck trauma.
Applying cervical spine collars to children who have suspected neck trauma is not the first action that the nurse should take. This is a priority intervention, but it can only be done after surveying the scene for potential hazards and making sure that it is safe to approach and touch the children.
C. Notify guardians of the emergency and injuries to their children.
Notifying guardians of the emergency and injuries to their children is not the first action that the nurse should take. This is a necessary step, but it can be delegated to another staff member or done after providing initial care to the children.
D. Survey the scene for potential hazards to staff and children.
Surveying the scene for potential hazards to staff and children is the correct answer. This is the first action that the nurse should take, according to the principles of emergency care. The nurse needs to assess the situation and ensure that there are no dangers such as fire, electricity, gas, or falling debris that could harm anyone at the scene. The nurse also needs to determine how many children are injured, how severe their injuries are, and what resources are available to help them.

D. Urine culture and sensitivity
Urine culture and sensitivity is not correct because it is not related to valproic acid therapy or its adverse effects.
