Keeping my blood pressure under control reduces my risk for a heart attack.

When I get out of bed in the morning, I should first sit for a few minutes and then stand.

I will be able to stop my anti-hypertensive medication when my blood pressure is normal.

Answer and Explanation

The Correct Answer is D

Choice A reason: I should continue to read the labels of foods I select at the grocery store is not a statement that indicates a need for further clarification by the nurse. This statement shows that the client understands the importance of choosing foods that are low in sodium, fat, and calories, which can help lower blood pressure and prevent complications.

Choice B reason: Keeping my blood pressure under control reduces my risk for a heart attack is not a statement that indicates a need for further clarification by the nurse. This statement shows that the client understands the benefits of pharmacologic therapy for hypertension, which can prevent or delay the development of cardiovascular disease.

Choice C reason: When I get out of bed in the morning, I should first sit for a few minutes and then stand is not a statement that indicates a need for further clarification by the nurse. This statement shows that the client understands how to prevent or minimize orthostatic hypotension, which is a possible side effect of some anti-hypertensive medications.

Choice D reason: I will be able to stop my anti-hypertensive medication when my blood pressure is normal is a statement that indicates a need for further clarification by the nurse. This statement shows that the client has a misconception about the nature and duration of pharmacologic therapy for hypertension. The nurse should explain that hypertension is a chronic condition that requires lifelong treatment and monitoring, and that stopping the medication abruptly can cause a rebound increase in blood pressure and increase the risk of complications.

Correct Answer is D

Explanation

Choice A reason: Vitamin B12 does not contribute to the increased production of RBCs after significant blood loss. Vitamin B12 is a type of vitamin that is essential for the normal formation and maturation of red blood cells (RBCs), which carry oxygen throughout the body. ¹ However, vitamin B12 does not increase the production of RBCs in response to blood loss. That is the role of erythropoietin, a hormone that stimulates the bone marrow to produce more RBCs. ²

Choice B reason: Vitamin B12 is not needed to prevent excessive production of red blood cells. Vitamin B12 is needed for the normal production of red blood cells, not for the prevention of overproduction. Excessive production of red blood cells, also known as polycythemia, can cause the blood to become thick and viscous, increasing the risk of clotting and stroke. ³ Polycythemia can be caused by various factors, such as smoking, dehydration, or genetic mutations, but not by a lack of vitamin B12.

Choice C reason: Vitamin B12 is not needed to prevent RBCs from sticking together. Vitamin B12 is needed for the normal formation and maturation of RBCs, not for the prevention of aggregation. RBCs can stick together and form clumps, also known as rouleaux, which can impair blood flow and oxygen delivery. Rouleaux can be caused by various factors, such as inflammation, infection, or cancer, but not by a lack of vitamin B12.

Choice D reason: Vitamin B12 is needed for the normal formation and maturation of RBCs, but it cannot be absorbed by the body without a substance called intrinsic factor. Intrinsic factor is a protein that is produced by the stomach and binds to vitamin B12, allowing it to be absorbed by the small intestine. ¹ Pernicious anemia is a type of anemia that occurs when the stomach does not produce enough intrinsic factor, leading to vitamin B12 deficiency. The only way to treat pernicious anemia is by giving vitamin B12 injections, which bypass the need for intrinsic factor.

A. I will call dietary to bring you breakfast. B. Food may interact with the dye that is used for the test. C. I will ask the health care provider if the test can be rescheduled. D. The procedure is usually completed on an empty stomach.

Correct Answer is D

Explanation

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.
