In preparation for a patient having a Schilling test, the nurse should explain that the test:

will confirm a diagnosis of G6PD anemia.

requires the patient to be NPO for 12 hours prior to the test.

is a 24-hour urine specimen collection test.

entails administration of methylcellulose prior to the test.

Answer and Explanation

The Correct Answer is C

Choice A reason: The Schilling test is not used to diagnose G6PD anemia, which is a genetic disorder that causes red blood cells to break down when exposed to certain substances. The Schilling test is used to measure how well the body absorbs vitamin B12 from the intestine. ¹²

Choice B reason: The Schilling test does not require the patient to be NPO (nothing by mouth) for 12 hours prior to the test. The patient can drink water, but should avoid food for 8 hours before the test. ²

Choice C reason: The Schilling test is a 24-hour urine specimen collection test. The patient is given a dose of radioactive vitamin B12 by mouth and another dose of nonradioactive vitamin B12 by injection. The urine is collected for 24 hours to measure how much of the radioactive vitamin B12 is excreted. This indicates how well the body absorbs vitamin B12 from the intestine. ¹²

Choice D reason: The Schilling test does not entail administration of methylcellulose prior to the test. Methylcellulose is a type of laxative that can interfere with the absorption of vitamin B12. The patient should avoid taking any laxatives, antacids, or antibiotics before the test. ²³

Correct Answer is D

Explanation

Choice A reason: This is a high-fat, high-sodium, and high-calorie meal that is not suitable for a client with hypertension. Fried foods, processed meats, and baked beans are sources of saturated fat and sodium that can raise blood pressure and cholesterol levels. Cake is a source of added sugar that can contribute to obesity and diabetes.

Choice B reason: This is a moderate-fat, moderate-sodium, and moderate-calorie meal that is not ideal for a client with hypertension. Fried flounder and tomato soup are sources of fat and sodium that can increase blood pressure. White rice is a refined carbohydrate that can spike blood sugar levels and increase the risk of diabetes.

Choice C reason: This is a high-fat, high-sodium, and high-calorie meal that is not appropriate for a client with hypertension. Barbecue pulled pork sandwich, mashed potatoes, and ice cream are sources of saturated fat and sodium that can elevate blood pressure and cholesterol levels. Fresh green beans are the only healthy component of this meal.

Choice D reason: This is a low-fat, low-sodium, and low-calorie meal that is suitable for a client with hypertension. Baked tuna, fresh broccoli, brown rice, and fresh cantaloupe are sources of lean protein, fiber, complex carbohydrates, vitamins, minerals, and antioxidants that can lower blood pressure and cholesterol levels, prevent obesity and diabetes, and promote cardiovascular health.

A. An early morning headache. B. Occasional nausea. C. A chronic cough. D. A dry mouth after eating.

Correct Answer is C

Explanation

Choice A reason: An early morning headache is not the most common side effect of lisinopril. Lisinopril is a drug that lowers blood pressure and prevents the complications of heart failure. ¹ It belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors, which work by relaxing the blood vessels and reducing the workload of the heart. ¹ Headache is a possible side effect of lisinopril, but it is not very frequent or specific to this drug. ²

Choice B reason: Occasional nausea is not the most common side effect of lisinopril. Lisinopril is a drug that lowers the blood pressure and prevents the complications of heart failure. ¹ It belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors, which work by relaxing the blood vessels and reducing the workload of the heart. ¹ Nausea is a possible side effect of lisinopril, but it is not very frequent or specific to this drug. ²

Choice C reason: A chronic cough is the most common side effect of lisinopril. Lisinopril is a drug that lowers the blood pressure and prevents the complications of heart failure. ¹ It belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors, which work by relaxing the blood vessels and reducing the workload of the heart. ¹ However, ACE inhibitors can also cause a dry, persistent cough that does not go away with time or treatment. ² This cough is due to the accumulation of a substance called bradykinin in the lungs, which irritates the airways and triggers the cough reflex. ³ The cough can be annoying and interfere with the quality of life of the client, but it is not harmful or dangerous. ²

Choice D reason: A dry mouth after eating is not the most common side effect of lisinopril. Lisinopril is a drug that lowers the blood pressure and prevents the complications of heart failure. ¹ It belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors, which work by relaxing the blood vessels and reducing the workload of the heart. ¹ Dry mouth is a possible side effect of lisinopril, but it is not very frequent or specific to this drug. ² Dry mouth can be caused by many factors, such as dehydration, medication, or disease. It can be relieved by drinking water, chewing gum, or using saliva substitutes.
