A nurse is providing teaching for a client who has diabetes and a new prescription for insulin glargine. Which of the following instructions should the nurse provide regarding this type of insulin?

Choice A reason: Tachycardia is a possible adverse effect of theophylline, as it is a methylxanthine that stimulates the central nervous system and the cardiac muscle. The nurse should instruct the client to monitor their pulse rate and report any palpitations, chest pain, or irregular heartbeat.

Choice B reason: Drowsiness is not a likely adverse effect of theophylline, as it is a stimulant that increases alertness and energy. The nurse should caution the client to avoid taking the medication close to bedtime, as it may cause insomnia.

Choice C reason: Constipation is not a common adverse effect of theophylline, as it does not affect the gastrointestinal motility or secretion. The nurse should advise the client to maintain a balanced diet, adequate fluid intake, and regular exercise to prevent constipation.

Choice D reason: Oliguria is not a typical adverse effect of theophylline, as it does not impair the renal function or cause fluid retention. The nurse should encourage the client to drink enough fluids to prevent dehydration and maintain a normal urine output.

Choice A reason: You should avoid alcohol intake while taking codeine, not limit it to 12 ounces daily. Alcohol can increase the risk of side effects such as drowsiness, dizziness, and respiratory depression.

Choice B reason: You should not expect to experience diarrhea while taking codeine. Codeine can cause constipation, not diarrhea. You should increase your fluid and fiber intake and use laxatives as prescribed to prevent constipation.

Choice C reason: You should not take the medication on an empty stomach to prevent nausea. Codeine can cause nausea and vomiting, especially on an empty stomach. You should take the medication with food or milk to reduce nausea.

Choice D reason: You should change positions slowly while taking codeine. Codeine can cause orthostatic hypotension, which is a sudden drop in blood pressure when you stand up. This can cause dizziness, fainting, and falls. You should change positions slowly and use caution when walking or climbing stairs.
