4. The client who has continuous nasointestinal tube feedings can receive SL medica-tion, so the nurse administers the SL isosorbide dinitrate under the tongue.
1. Medication is never added to the formula as a method of administering routine medication because this method causes a medication error: incorrect administration time. Many medications need to be administered over a specific period and, when mixed into formula, are administered over a longer period, thus potentially affecting the drug's therapeutic effect.
2. Sublingual tablets cannot be administered directly into the intestines without caus-ing a medication error because the tablets are formulated for absorption through the oral mucosa. The medication's pharmacodynamics and the body's pharmacokinetics are disrupted when the route of administration is altered.
3. Asking for nitroglycerine ointment is unnecessary.
