Which is true regarding the unit dose drug distribution system?

Correct Answer: C

Rationale: The unit dose drug distribution system uses single unit packages of drugs dispensed to fill each dose requirement as it is ordered.

Correct Answer: D

Rationale: Standing orders state the frequency of medication dosages to be administered or indicate the time frame of administration. Renewal orders require the physician to review medications that have expired orders, as determined by facility policy. Renewal policies facilitate physician verification of the necessity to continue a medication beyond a usual time frame and help ensure patient safety. Single dose and stat orders are not the same. PRN medications are not ordered a mandatory number of times, although a maximum number might be specified.

Correct Answer: C

Rationale: Medications should not be mixed with a large amount of food or beverage because patients may miss the full dose if they do not consume the entire amount. If the entire bottle is not consumed, the nurse will have difficulty determining how much dose was received. If medications interact with formula in vivo, package information will indicate this.

Correct Answer: B

Rationale: Transdermal patches provide more consistent blood levels. Cutting the patch is not recommended. Drugs given transdermally can still produce side effects and toxicity.

Correct Answer: D

Rationale: Intradermal injections should be given with a 25- to 27-gauge, 3/8\- to 5/8\"-long needle. The needle should be inserted at a 10- to 15-degree angle. The area should not be massaged. The nurse measures the area of induration not erythema."""
