A nurse in a mental health clinic receives a request from a client who is undergoing psychotherapy to obtain a copy of the therapist’s notes.

This prescription is complete because it includes the medication name, dose, route, and frequency.

A complete prescription should also include the client’s name, date, time, signature of the prescriber, and any special instructions.

Choice A is wrong because it does not specify the dose of cimetidine.

PO twice daily is not enough information to administer the medication safely.

Choice B is wrong because it does not specify the frequency of tetracycline.

200 mg PO is not enough information to administer the medication safely.

Choice C is wrong because it does not specify the route of epoetin alfa.

150 units/kg three times weekly is not enough information to administer the medication safely.

Normal ranges for digoxin are 0.5 to 2 ng/mL for heart failure and 0.8 to 2 ng/mL for atrial fibrillation.

Normal ranges for cimetidine are 50 to 150 ng/mL.

Normal ranges for tetracycline are 1 to 10 mcg/mL.

Normal ranges for epoetin alfa are not applicable as it is a synthetic hormone that stimulates red blood cell production.

This is because abruptly stopping TPN can cause hypoglycemia, which is a low blood sugar level that can cause shakiness, diaphoresis, confusion, and seizures. Therefore, infusing dextrose 10% in water temporarily at the same rate as the TPN can prevent this adverse effect. Dextrose 10% in water is a hypertonic solution that contains 340 calories per liter and can maintain the client’s blood glucose level until the new TPN bag arrives.

Choice A is wrong because giving 500 mL of lactated Ringer’s solution would not provide enough calories or glucose to prevent hypoglycemia. Lactated Ringer’s solution is an isotonic solution that contains electrolytes but no calories or glucose.

Choice B is wrong because temporarily discontinuing the infusion would cause hypoglycemia, which can be life-threatening for the client.

Choice C is wrong because slowing the TPN infusion rate would also cause hypoglycemia, as the client would receive less calories and glucose than prescribed.
