Flashcards in med admin test 26-50 Deck (25):
A severely burned patient requires 4,500 mL of isotonic crystalloid solution over 8 hours, so medical control orders you to begin the infusion in the field. If your administration set allows 10 gtts/mL, at how many gtts/min will you set the IV flow rate in order to deliver the ordered amount of fluid?
Medical asepsis is MOST accurately defined as:
A. the practice of preventing contamination of the patient.
B. ensuring that all patient care supplies remain sterile.
C. the destruction of all living organisms using heat or gas.
D. preventing infection of the patient by using clean supplies.
The MOST common inhaled medication is:
If a 10-mL vial contains 1 mg of a drug, how many mg/mL are present?
When infusing crystalloid solutions through an IO catheter in an unconscious adult, you should:
A. give 200 mL at a time.
B. use a pressure infuser device.
C. deliver the solution via syringe.
D. inject lidocaine prior to the infusion.
If you give a medication via the oral route in the prehospital setting, you should give it early because:
A. toxic levels are reached easily.
B. its onset of action is unpredictable.
C. the patient may aspirate the medication.
D. absorption via this route is slow.
Large protruding arm veins in an otherwise healthy adult can be difficult to cannulate because they often:
A. roll from side to side during the cannulation attempt.
B. are covered by thick skin that bends the IV catheter.
C. constrict in response to insertion of the IV catheter.
D. rupture spontaneously when punctured with the needle.
Following return of spontaneous circulation, you are ordered to begin a lidocaine infusion at 3 mg/min on your 50-year-old patient. You add 2 g of lidocaine to a 500-mL bag of normal saline and are using a microdrip administration set. At how many drops per minute (gtts/min) will you set the IV flow rate?
Thrombophlebitis is MOST commonly caused by:
A. abuse of IV drugs.
B. lapses in aseptic technique.
C. long-term IV therapy.
D. any type of hypotonic solution
Which of the following statements regarding calcium is correct?
A. Patients with ataxia should be suspected of being hypocalcemic.
B. Calcium can react completely with 1 mEq of a singly charged anion.
C. Calcium is needed for bone growth and proper blood clotting.
D. Abdominal cramps are a sign of an increased level of serum calcium
In contrast to an antiseptic, a disinfectant is:
A. not intended to be used on nondisposable patient care equipment.
B. toxic to living tissues and should never be used on a patient.
C. capable of destroying pathogens but is not toxic to living tissues.
D. used to cleanse an area before performing an invasive procedure.
Drug reconstitution involves:
A. adding 3 mL to 5 mL of sterile saline to an already existing liquid medication to achieve the appropriate concentration.
B. injecting diluent or sterile water from one vial into the vial that contains the powdered form of the medication.
C. injecting a certain volume of a medication into a 500-mL bag of normal saline to achieve the correct concentration.
D. shaking a medication vial vigorously so that the drug is appropriately separated from its liquid base.
Major cations of the body include all of the following, EXCEPT:
Pyrogenic reactions can be largely avoided by:
A. inspecting the IV solution carefully before use.
B. premedicating the patient with 1 gram of acetaminophen.
C. determining if the patient has any allergies.
D. keeping the piercing spike sterile after it is exposed.
Osmosis occurs when:
A. water moves from an area of lower solute concentration to an area of higher solute concentration.
B. solutes move from an area of lower water concentration to an area of higher water concentration.
C. water moves from an area of higher solute concentration to an area of lower solute concentration.
D. solutes move from an area of higher water concentration to an area of lower water concentration.
After inserting the needle during an intramuscular or subcutaneous injection, but before delivering the medication, you should:
A. look in the barrel of the syringe for blood.
B. inquire about any medication allergies.
C. pull back on the plunger to aspirate for blood.
D. ensure that you stretch the skin taut.
If you receive a medication order from on-line medical control that seems inappropriate to you, you should:
A. ask the physician to repeat the order.
B. look up the correct dose in your field guide.
C. administer the drug as ordered and document it.
D. refuse to administer the medication.
You are treating an unconscious 39-year-old man who overdosed on heroin. You are unable to establish an IV line because his veins are severely sclerosed, and your protocols do not allow for IO cannulation. You should:
A. administer naloxone via the mucosal atomizer device.
B. intubate the patient and give Narcan via the ET tube.
C. use the subcutaneous route to administer Narcan.
D. assist ventilations and transport immediately
Cations are electrolytes that have an overall __________ charge, and anions are electrolytes that have an overall ___________ charge.
A. positive, negative
B. negative, positive
C. negative, neutral
D. neutral, positive
All of the following are examples of colloid solutions, EXCEPT:
A. lactated Ringer's.
When changing an IV bag, it is important to:
A. attach a new fluid administration set to the bag.
B. ensure that the tubing is completely depleted of fluid.
C. ensure that fluid remains in the drip chamber.
D. allow the bag to become completely depleted of fluid.
IO cannulation is contraindicated in all of the following situations, EXCEPT:
A. penetrating thoracic trauma.
B. the presence of a peripheral IV line.
C. known osteogenesis imperfecta.
D. bilateral knee replacements. Incorrect
All of the following are peripheral veins, EXCEPT the:
A. external jugular vein.
B. lower extremity veins.
C. subclavian vein.
D. veins of the hand.
The main benefit of using a prefilled medication syringe is that:
A. it does not require you to draw up each individual medication dose.
B. there is no need to expel air from the syringe prior to giving the drug
C. all of the contents of a prefilled syringe are administered at one time.
D. it is made of plastic and is less likely to break or get damaged.
