Extract:
Question 1 of 5
A nurse is performing a pain assessment, noting 5 on a 10-point scale, for a postoperative patient who is 24 hours post procedure. Which type of order should the nurse anticipate that the health-care provider has written?
Correct Answer: A
Rationale: Standing orders are prewritten orders for specific situations. For a patient postprocedure, standing orders might include pain management protocols that would be activated based on the pain assessment.
Question 2 of 5
which of the following is a sign of anaphylaxis?
Correct Answer: C
Rationale: Wheezing is a classic sign of anaphylaxis, indicating airway constriction due to a severe allergic reaction.
Question 3 of 5
A patient is scheduled for diagnostic testing. Which medication should the nurse anticipate that the health-care provider would order?
Correct Answer: A
Rationale: Barium sulfate is used as a contrast agent in radiographic diagnostic testing, particularly for imaging the gastrointestinal tract.
Question 4 of 5
The LPN/LVN is aware that the bioavailability of a drug is based on multiple factors. Which factor(s) would be included?
Correct Answer: A,B,E
Rationale: Molecular weight: Drugs with lower molecular weight tend to have higher bioavailability because they can more easily pass through biological membranes. Fat or liquid solubility: Drugs that are fat-soluble can cross cell membranes more easily, affecting their bioavailability. Presence of food: Food in the stomach can either enhance or inhibit drug absorption, depending on the drug's characteristics.
Question 5 of 5
The LPN/LVN is aware of the drug cycle that begins with the administration of a drug. Which factor(s) would influence the amount of time needed to complete the drug cycle of a drug?
Correct Answer: A,C,D,E
Rationale: Age affects drug metabolism and excretion. Older adults often have slower metabolism and impaired organ function, which can prolong the drug cycle. The brand or generic status of a drug does not typically influence the drug cycle. The route of administration significantly influences the onset, intensity, and duration of a drug's action. The health of organs like the liver and kidneys is crucial because these organs are involved in the metabolism and excretion of drugs.
