When educating a patient about Lorazepam (Ativan), the nurse should advise against the concurrent use of which substance?

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: This is correct. Hypertension is a contraindication for taking pseudoephedrine. Pseudoephedrine is a decongestant that shrinks the blood vessels in the nasal passages and relieves congestion. However, it can also increase the blood pressure and the heart rate, which can worsen hypertension and increase the risk of stroke, heart attack, or kidney damage. The nurse should advise the client to avoid pseudoephedrine and use other methods to relieve sinus congestion, such as saline nasal spray, steam inhalation, or humidifier.

Choice B reason: This is incorrect. Diverticulitis is not a contraindication for taking pseudoephedrine. Diverticulitis is a condition where small pouches in the colon become inflamed and infected. It can cause symptoms such as abdominal pain, fever, nausea, or constipation. Pseudoephedrine does not affect the colon or the inflammation directly, but it can cause dehydration, which can worsen constipation and diverticulitis. The nurse should advise the client to drink plenty of fluids and eat a highfiber diet to prevent constipation and diverticulitis.

Choice C reason: This is incorrect. Migraines are not a contraindication for taking pseudoephedrine. Migraines are severe headaches that are often accompanied by nausea, vomiting, or sensitivity to light and sound. They can be triggered by various factors, such as stress, hormones, or food. Pseudoephedrine does not cause migraines directly, but it can interact with some migraine medications, such as triptans, which are used to treat acute migraine attacks. The combination of pseudoephedrine and triptans can increase the blood pressure and the risk of serotonin syndrome, a serious condition that causes agitation, confusion, tremors, or seizures. The nurse should advise the client to check with their doctor before taking pseudoephedrine and triptans together.

Choice D reason: This is incorrect. Eczema is not a contraindication for taking pseudoephedrine. Eczema is a skin condition that causes dry, itchy, and inflamed skin. It can be caused by various factors, such as allergies, irritants, or genetics. Pseudoephedrine does not affect the skin or the inflammation directly, but it can cause dryness of the mucous membranes, such as the mouth, nose, or eyes. The nurse should advise the client to use a moisturizer, a lip balm, and artificial tears to prevent dryness and irritation of the skin and the mucous membranes.
