A diabetic client has an order for a CT of the abdomen with contrast. The nurse should assess the client's medications for which drug prior to sending the client to radiology?

Glargine

Metformin

Famotidine

Glucagon

Answer and Explanation

The Correct Answer is B

Choice A reason: This choice is incorrect because glargine is not a drug that needs to be assessed before a CT scan with contrast. Glargine is a long-acting insulin that lowers blood sugar levels in people with diabetes. It is injected once a day, usually at bedtime, and works for 24 hours. The nurse should monitor the client's blood sugar levels and adjust the dose of glargine as needed, but it does not interfere with the CT scan or the contrast dye.

Choice B reason: This choice is correct because metformin is a drug that needs to be assessed before a CT scan with contrast. Metformin is an oral medication that lowers blood sugar levels in people with diabetes. It works by reducing the amount of glucose produced by the liver and increasing the sensitivity of the cells to insulin. However, metformin can cause a rare but serious condition called lactic acidosis, which is a buildup of lactic acid in the blood that can cause symptoms such as nausea, vomiting, abdominal pain, muscle weakness, and breathing problems. The risk of lactic acidosis is increased when metformin is combined with contrast dye, which can affect the kidney function and the clearance of metformin from the body. The nurse should check the client's kidney function and the dose and timing of metformin before the CT scan. The nurse should also instruct the client to stop taking metformin before and after the CT scan, as directed by the provider.

Choice C reason: This choice is incorrect because famotidine is not a drug that needs to be assessed before a CT scan with contrast. Famotidine is an antacid that reduces the amount of acid in the stomach. It is used to treat conditions such as gastroesophageal reflux disease (GERD), ulcers, and gastritis. It does not affect the blood sugar levels or the kidney function, and it does not interact with the contrast dye. The nurse should administer famotidine as prescribed and monitor the client's gastrointestinal symptoms, but it does not require any special precautions before the CT scan.

Choice D reason: This choice is incorrect because glucagon is not a drug that needs to be assessed before a CT scan with contrast. Glucagon is a hormone that raises blood sugar levels in people with diabetes. It is used as an emergency treatment for severe hypoglycemia (low blood sugar), when the person is unconscious or unable to swallow. It is injected into a muscle or under the skin, and it works by stimulating the liver to release glucose into the blood. The nurse should have glucagon available in case of hypoglycemia, but it does not affect the CT scan or the contrast dye.

Correct Answer is D

Explanation

Choice A reason: This choice is incorrect because it does not provide a numerical answer to the question.

Choice B reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is lower than the correct one, which is not true.

Choice C reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is higher than the correct one, which is not true.

Choice D reason: This choice is correct because it is the result of dividing the ordered dose (3.5 mg) by the concentration of the vial (1 mg/mL). The formula for calculating the volume to be drawn up is:

Volume = Dose/Concentration

Therefore, the volume to be drawn up is:

Volume = 3.5 mg/(1 mg/mL) = 3.5 mL

A. Maintain healthy weight B. Avoid cigarettes and other nicotine products C. Importance of regular exercise D. Positive stress management techniques E. Healthy low fat diet options

Correct Answer is ["A","B","C","E"]

Explanation

Choice A reason: Maintaining a healthy weight is important for lowering cholesterol levels and reducing the risk of cardiovascular disease. Obesity is associated with higher levels of LDL-cholesterol (the "bad" cholesterol) and lower levels of HDL-cholesterol (the "good" cholesterol). Losing weight can improve these ratios and lower blood pressure. ¹

Choice B reason: Avoiding cigarettes and other nicotine products is essential for preventing cardiovascular disease. Smoking damages the blood vessels and increases the risk of atherosclerosis, which is the buildup of plaque in the arteries. Smoking also lowers HDL-cholesterol and raises triglycerides, another type of fat in the blood. Quitting smoking can improve cholesterol levels and lower the risk of heart attack and stroke. ²

Choice C reason: Importance of regular exercise is another key factor for improving cholesterol levels and cardiovascular health. Exercise helps to lower LDL-cholesterol and raise HDL-cholesterol, as well as lower blood pressure and blood sugar. Exercise also strengthens the heart muscle and improves blood flow. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, or a combination of both. ³

Choice D reason: Positive stress management techniques are not directly related to cholesterol levels or statin medications, but they may have some benefits for cardiovascular health. Stress can increase blood pressure and heart rate, and may trigger unhealthy behaviors such as smoking, drinking, or overeating. Stress can also affect the immune system and inflammation, which may contribute to atherosclerosis. Learning to cope with stress in healthy ways, such as meditation, yoga, breathing exercises, or counseling, may help to lower the risk of cardiovascular disease. ⁴

Choice E reason: Healthy low fat diet options are an important part of lowering cholesterol levels and preventing cardiovascular disease. A diet that is high in saturated fat, trans fat, and cholesterol can raise LDL-cholesterol and lower HDL-cholesterol. A diet that is low in fat and high in fiber, fruits, vegetables, whole grains, and lean protein can lower LDL-cholesterol and raise HDL-cholesterol. Some foods, such as oats, nuts, soy, and fish, may have additional benefits for cholesterol levels. .
