The nurse is preparing to administer Reglan to a patient. She is most concerned by the following information in the patient's medical record?

Choice A reason: This is incorrect. Reviewing the patient’s previous blood glucose levels may not be helpful in determining the correct dose of insulin, as the blood glucose level can fluctuate depending on various factors, such as food intake, activity, stress, and illness. The previous blood glucose levels may not reflect the current insulin needs of the patient¹.

Choice B reason: This is incorrect. No review is not an option before administering insulin, as insulin is a highalert medication that can cause serious harm if given incorrectly. The nurse should always check the patient’s blood glucose level, the insulin order, the insulin type, the insulin dose, the insulin expiration date, and the insulin injection site before giving insulin.

Choice C reason: This is correct. Reviewing the Regular insulin sliding scale for administration in the patient’s electronic medical record is the best action to determine the correct dose of insulin. A sliding scale is a chart of insulin dosages based on blood glucose level and mealtime. It is used to adjust the insulin dose according to the patient’s blood glucose level and insulin sensitivity. The nurse should follow the sliding scale protocol and verify the insulin dose with another nurse before administering it.

Choice D reason: This is incorrect. Reviewing the patient’s previous insulin administration doses may not be helpful in determining the correct dose of insulin, as the insulin dose may vary depending on the patient’s blood glucose level and insulin sensitivity. The previous insulin doses may not reflect the current insulin needs of the patient¹.

Choice A reason: Tinnitus is a rare side effect of Flexeril, which is a medication that relaxes the muscles and relieves pain and stiffness¹. Tinnitus is a ringing or buzzing sound in the ears that can be caused by various factors, such as ear infections, noise exposure, or certain medications. Flexeril does not affect the auditory system directly, but it can cause confusion or dizziness, which may worsen the perception of tinnitus.

Choice B reason: Drowsiness is the most common side effect of Flexeril, which is a medication that relaxes the muscles and relieves pain and stiffness¹. Drowsiness occurs because Flexeril has sedative and anticholinergic properties, which means that it blocks the action of acetylcholine, a neurotransmitter that regulates arousal and alertness. Flexeril can impair the mental and physical abilities, especially in elderly patients or those who take other medications that cause drowsiness¹. The nurse should educate the patient about the risk of drowsiness and advise them to avoid driving or operating machinery while taking Flexeril.

Choice C reason: Diarrhea is not a common side effect of Flexeril, which is a medication that relaxes the muscles and relieves pain and stiffness¹. Diarrhea is a condition that causes loose or watery stools, which can be caused by various factors, such as infections, food intolerance, or certain medications. Flexeril does not affect the gastrointestinal system directly, but it can cause dry mouth, nausea, or constipation, which may alter the bowel movements¹.

Choice D reason: Palpitations are not a common side effect of Flexeril, which is a medication that relaxes the muscles and relieves pain and stiffness¹. Palpitations are a sensation of rapid or irregular heartbeat, which can be caused by various factors, such as stress, anxiety, caffeine, or certain medications. Flexeril does not affect the cardiac system directly, but it can lower the blood pressure or interact with other medications that affect the heart rate, such as betablockers or antidepressants¹.
