ANS:

Give Effexor extended release tablet enteric coated 75 mg after the morning meal with a full glass of water.

PTS:    1

1. Why do you think XR, ent, DR, SR, and SL tablets should never be crushed?

ANS:

Crushing these tablets would cancel the delayed or extended or sustained release. The patient might then have an adverse drug event from side effects of too much of the medication being released and absorbed too soon. The medication may be very irritating to the mucosa of the GI tract if broken down before it leaves the esophagus or stomach.

PTS:    1

1. Why do you think unscored tablets should never be cut?

ANS:

The medication may be unevenly distributed within the tablet. The cut probably would not be precise. With either of the foregoing problems, one part would have too much and one part would have too little of the medication. The patient would receive the wrong dose.

PTS:    1

1. Why do you think some medications must be given with food, or given after meals, and/or the patient must remain upright for 30 minutes after the medication is administered?

ANS:

The medications may be too irritating to mucosa on an empty stomach or may cause nausea.

Staying upright for 30 minutes after a medication is administered with a full glass of water helps prevent reflux of irritating medications before it reaches the stomach. This helps prevent irritation of the esophagus by a potentially caustic substance.

PTS:    1

1. If the nurse does not document the medication promptly after administration, what adverse event might occur during that shift?

ANS:

Right route is violated if route is changed without the prescribers order. The nurse is liable if an adverse event occurs.
