The nurse is caring for a client who is taking metformin (Glucophage) for hyperglycemia prior to admission. The nurse would question the following order for this client:

CT scan with contrast

Chest X-ray 1 view

V/Q scan

Bilateral lower extremity ultrasound

Answer and Explanation

The Correct Answer is A

Choice A reason: CT scan with contrast is an order that the nurse should question for the client who is taking metformin for hyperglycemia. Metformin is a medication that lowers the blood glucose level by decreasing the hepatic glucose production and increasing the insulin sensitivity¹. Metformin can cause a rare but serious complication called lactic acidosis, which is a buildup of lactic acid in the blood that can cause symptoms such as weakness, nausea, vomiting, or breathing problems. CT scan with contrast involves injecting iodinated contrast material into the bloodstream, which can affect the kidney function and increase the risk of lactic acidosis in patients taking metformin. The nurse should consult with the prescriber and the pharmacist about the need to stop metformin before and after the CT scan with contrast, and to monitor the kidney function and the blood glucose level of the client.

Choice B reason: Chest X-ray 1 view is not an order that the nurse should question for the client who is taking metformin for hyperglycemia. Chest X-ray is a diagnostic test that uses a small amount of radiation to produce images of the lungs, heart, and chest wall. Chest X-ray does not involve any contrast material or affect the kidney function or the blood glucose level. The nurse should follow the standard precautions and procedures for performing a chest X-ray, such as verifying the client's identity, checking for pregnancy, removing any metal objects, and positioning the client properly.

Choice C reason: V/Q scan is not an order that the nurse should question for the client who is taking metformin for hyperglycemia. V/Q scan is a diagnostic test that measures the ventilation and perfusion of the lungs, and can detect any abnormalities such as pulmonary embolism or chronic obstructive pulmonary disease. V/Q scan involves injecting a radioactive tracer into the bloodstream and inhaling a radioactive gas, which are then detected by a special camera. V/Q scan does not affect the kidney function or the blood glucose level. The nurse should follow the standard precautions and procedures for performing a V/Q scan, such as verifying the client's identity, checking for allergies, explaining the procedure, and monitoring the vital signs.

Choice D reason: Bilateral lower extremity ultrasound is not an order that the nurse should question for the client who is taking metformin for hyperglycemia. Bilateral lower extremity ultrasound is a diagnostic test that uses sound waves to produce images of the blood vessels in the legs, and can detect any abnormalities such as deep vein thrombosis or peripheral arterial disease. Bilateral lower extremity ultrasound does not involve any contrast material or affect the kidney function or the blood glucose level. The nurse should follow the standard precautions and procedures for performing a bilateral lower extremity ultrasound, such as verifying the client's identity, explaining the procedure, and applying a gel and a probe to the legs.

Correct Answer is C

Explanation

Choice A reason: Past medical history of benign prostatic hyperplasia (BPH) is not a contraindication or a concern for administering Reglan, which is a medication that stimulates the motility of the upper gastrointestinal tract and treats nausea, heartburn, and gastroparesis¹. Reglan does not affect the prostate or urinary function.

Choice B reason: Blood pressure of 132/82 is slightly above the normal range of 120/80, but it is not a cause for concern or a reason to withhold Reglan. Reglan can lower the blood pressure by reducing the fluid volume and preventing sodium retention¹. The nurse should monitor the blood pressure regularly, but does not need to notify the health care provider about this finding.

Choice C reason: Allergy to corn is a concern for administering Reglan, as some formulations of Reglan may contain corn starch as an inactive ingredient. Corn starch can trigger an allergic reaction in people who are sensitive to corn, causing symptoms such as rash, itching, swelling, or anaphylaxis. The nurse should check the label of the Reglan product and avoid using it if it contains corn starch. The nurse should also notify the health care provider and the pharmacy about the patient's allergy and request an alternative medication or formulation.

Choice D reason: Past medical history of gout is not a contraindication or a concern for administering Reglan, which is a medication that stimulates the motility of the upper gastrointestinal tract and treats nausea, heartburn, and gastroparesis¹. Reglan does not affect the uric acid levels or the joints.

A. Advise the client to avoid highfiber foods with the medication. B. Encourage the client to consume a potassium rich diet. C. Assess the client’s respiratory rate and oxygen saturation. D. Instruct the client to increase fluid intake to prevent dehydration.

Correct Answer is C

Explanation

Choice A reason: Advise the client to avoid highfiber foods with the medication is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix does not interact with highfiber foods or affect the digestion directly. Highfiber foods can actually help prevent or treat constipation, which can be a side effect of Lasix. The nurse should encourage the client to eat a balanced and nutritious diet, unless they have any dietary restrictions or allergies.

Choice B reason: Encourage the client to consume a potassium rich diet is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can also cause the loss of potassium in the urine, which can lead to hypokalemia, a condition that causes muscle weakness, cramps, arrhythmias, or cardiac arrest. The nurse should monitor the serum potassium level and administer potassium supplements or potassiumsparing diuretics as prescribed to prevent hypokalemia. Consuming a potassium rich diet may not be sufficient or safe to correct the potassium imbalance caused by Lasix, especially in clients with kidney impairment or other medications that affect the potassium level.

Choice C reason: Assess the client’s respiratory rate and oxygen saturation is the most appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can help reduce the fluid overload and congestion in the lungs, which can cause shortness of breath, difficulty breathing, fatigue, and low oxygen levels in clients with heart failure. The nurse should assess the client’s respiratory rate and oxygen saturation to evaluate the severity of the pulmonary edema and the effectiveness of the Lasix therapy. The nurse should also monitor the client’s vital signs, fluid intake and output, and weight to ensure adequate fluid balance and hemodynamic stability.

Choice D reason: Instruct the client to increase fluid intake to prevent dehydration is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can cause dehydration, which can lead to symptoms such as thirst, dry mouth, dark urine, and fatigue. However, increasing fluid intake to prevent dehydration can worsen the fluid overload and congestion in the lungs, which can cause shortness of breath, difficulty breathing, fatigue, and low oxygen levels in clients with heart failure. The nurse should advise the client to drink enough fluids to maintain hydration, but not to exceed the prescribed fluid restriction, which is usually around 1.52 liters per day. The nurse should also educate the client about the signs and symptoms of dehydration and fluid overload, and when to seek medical attention.
