The client, who is scheduled for a nuclear stress test, tells the nurse that the breakfast tray was not delivered and complains of hunger. The nurse's best response is:

I will call dietary to bring you breakfast.

Food may interact with the dye that is used for the test.

I will ask the health care provider if the test can be rescheduled.

The procedure is usually completed on an empty stomach.

Answer and Explanation

The Correct Answer is D

Choice A reason: I will call dietary to bring you breakfast is not the best response by the nurse. This response may imply that the nurse is willing to compromise the test results or the client's safety by allowing them to eat before the test. The nurse should explain the rationale for fasting and offer the client some water or ice chips if allowed.

Choice B reason: Food may interact with the dye that is used for the test is not the best response by the nurse. This response may be partially true, but it is not specific or clear enough to justify the need for fasting. The nurse should explain that food can affect the absorption and distribution of the radioactive tracer that is injected into the bloodstream for the test, and that eating can also interfere with the quality of the images.

Choice C reason: I will ask the health care provider if the test can be rescheduled is not the best response by the nurse. This response may suggest that the nurse is not confident or knowledgeable about the test protocol or the client's condition. The nurse should explain the importance and urgency of the test and reassure the client that they will be able to eat after the test is done.

Choice D reason: The procedure is usually completed on an empty stomach is the best response by the nurse. This response is accurate and concise, and it informs the client of the standard preparation for the test. The nurse should also provide more details about the test procedure and the expected duration, and answer any questions or concerns that the client may have.

Correct Answer is A

Explanation

Choice A reason: This is the correct answer. Stool for occult blood is a diagnostic test that detects the presence of hidden blood in the feces. This can indicate bleeding in the gastrointestinal tract, which is the most common cause of chronic iron deficiency anemia. Iron deficiency anemia is a condition where the body does not have enough iron to produce hemoglobin, the protein that carries oxygen in the red blood cells.

Choice B reason: Vitamin B12 level is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Vitamin B12 level is a blood test that measures the amount of vitamin B12 in the body. Vitamin B12 is a nutrient that is essential for the production of red blood cells and the maintenance of the nervous system. Vitamin B12 deficiency can cause pernicious anemia, a type of megaloblastic anemia where the red blood cells are large and immature.

Choice C reason: Schilling's test is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Schilling's test is a urine test that evaluates the absorption of vitamin B12 in the body. It involves giving the client an oral dose of radioactive vitamin B12 and an intramuscular injection of non-radioactive vitamin B12. The urine is then collected and measured for the amount of radioactive vitamin B12. Schilling's test can help diagnose pernicious anemia and other causes of vitamin B12 malabsorption.

Choice D reason: Bone marrow aspiration study is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Bone marrow aspiration study is a procedure that involves taking a sample of bone marrow from the hip or sternum and examining it under a microscope. Bone marrow is the soft tissue inside the bones that produces blood cells. Bone marrow aspiration study can help diagnose various blood disorders, such as leukemia, lymphoma, and aplastic anemia.

A. Decreased hair is most likely a hereditary condition and nail changes are related to fungus. B. A blood clot may be forming and the client needs immediate intervention. C. Decreased oxygen to the tissues causes changes in hair growth and nail texture. D. Depending on the client's age, the findings may be normal.

Correct Answer is D

Explanation

Choice A reason: Decreased hair is most likely a hereditary condition and nail changes are related to fungus is not the statement that describes the cause of this finding. This statement is not based on evidence and does not explain the relationship between peripheral vascular disease and the observed changes in the legs and feet.

Choice B reason: A blood clot may be forming and the client needs immediate intervention is not the statement that describes the cause of this finding. This statement is an alarmist and inaccurate interpretation of the finding. A blood clot would cause more acute and severe symptoms, such as pain, swelling, redness, and warmth in the affected area.

Choice C reason: Decreased oxygen to the tissues causes changes in hair growth and nail texture is the statement that describes the cause of this finding. This statement is based on the pathophysiology of peripheral vascular disease, which is a chronic condition that reduces the blood flow to the extremities due to atherosclerosis or inflammation of the blood vessels. The reduced blood flow leads to tissue ischemia and necrosis, which can manifest as hair loss, thickening and yellowing of the nails, skin ulcers, and gangrene.

Choice D reason: Depending on the client's age, the findings may be normal is not the statement that describes the cause of this finding. This statement is a vague and dismissive response that does not address the underlying problem of peripheral vascular disease. The findings are not normal for any age group and require further assessment and intervention.
