The nurse working in a preoperative admitting unit administers an anticholinergic
medication to a patient before surgery. What is the purpose of this drug in the
preoperative setting?
A. Control the heart rate
B. Reduce oral and gastrointestinal secretions
C. Relax the patient
D. Reduce urinary frequency
Give this one a try later!
, B. Reduce oral and gastrointestinal secretions
Rationale: Anticholinergic drugs are given preoperatively to control oral
and gastrointestinal secretions during surgery. The other options are
incorrect.
The nurse is preparing to administer dopamine. Which is the correct technique for
administering dopamine?
A. Continuous IV infusion with an infusion pump
B. Intravenous (IV) push injection
C. Intermittent IV infusions (IV piggyback)
D. Orally
Give this one a try later!
A. Continuous IV infusion with an infusion pump
Rationale: Dopamine is available only as an IV injectable drug and is given
by continuous infusion, using an infusion pump. The other options are
incorrect.
The nurse is administering parenteral drugs. Which statement is true regarding
parenteral drugs?
A. Parenteral drugs bypass the first-pass effect.
B. Absorption of parenteral drugs is affected by reduced blood flow to the stomach.
C. Absorption of parenteral drugs is faster when the stomach is empty.
D. Parenteral drugs exert their effects while circulating in the bloodstream.
Give this one a try later!
, A. Parenteral drugs bypass the first-pass effect.
Rationale: Drugs given by the parenteral route bypass the first-pass effect.
Reduced blood flow to the stomach and the presence of food in the
stomach apply to enteral drugs (taken orally), not to parenteral drugs.
Parenteral drugs must be absorbed into cells and tissues from the
circulation before they can exert their effects: they do not exert their
effects while circulating in the bloodstream.
During a teaching session about self-monitoring while taking a beta blocker at home,
the nurse has taught the patient to take his apical pulse daily for 1 minute. If the pulse
rate decreases to less than 60 beats/min, the nurse will instruct the patient to:
A. reduce the dose of his beta blocker by half.
B. notify his prescriber.
C. continue the medication because this is an expected effect.
D. skip the medication dose that day, and check his pulse again the next day.
Give this one a try later!
B. notify his prescriber.
Rationale: Cardiac depression can occur with beta blockers, so instruct the
patient to contact his prescriber if his pulse rate decreases to less than 60
per minute. The medication dose may need to be changed, but it is not
appropriate for the nurse to change the dosage. The other options are
incorrect.
During discharge patient teaching, the nurse reviews prescriptions with a patient.
Which statement is correct about refills for an analgesic that is classified as Schedule
C-III?
A. The patient may have no more than five refills in a 6-month period.
B. Refills are allowed only by written prescription.
