Which erythrocyte characteristic would the nurse expect to see in the laboratory findings for a patient who has experienced acute blood loss?
Microcytic.
Normocytic.
Hypochromic.
Megaloblastic.
The Correct Answer is B
The correct answer is: B. Normocytic.
Choice A rationale: Microcytic erythrocytes, or smaller-than-normal red blood cells, are typically seen in chronic conditions like iron deficiency anemia, not acute blood loss.
Choice B rationale: Normocytic erythrocytes, or normal-sized red blood cells, are usually seen in acute blood loss as the body's initial response doesn't alter the size of red blood cells.
Choice C rationale: Hypochromic erythrocytes, or paler-than-normal red blood cells, are more common in chronic anemia states such as iron deficiency.
Choice D rationale: Megaloblastic erythrocytes, or abnormally large red blood cells, are seen in conditions like vitamin B12 or folate deficiency, not in acute blood loss.

Correct Answer is C
Explanation
Choice A rationale:
While pregnancy can contribute to increased blood pressure, it is not the priority question in this scenario. The sudden rise in blood pressure could indicate a hypertensive crisis, which needs immediate attention.
Choice B rationale:
Urination is not directly related to sudden rises in blood pressure. While urinary issues could be a sign of certain conditions, they are not the priority when dealing with a hypertensive emergency.
Choice C rationale:
A sudden rise in blood pressure can lead to symptoms such as headache and confusion, which could indicate a hypertensive crisis. This question is crucial to assess neurological symptoms, which can be indicative of target organ damage due to hypertension.
Choice D rationale:
Antiseizure medications are not directly related to sudden increases in blood pressure. Neurological symptoms (like those in choice C) are more indicative of a hypertensive crisis and require immediate attention.
Correct Answer is D
Explanation
Choice A rationale:
Triple-drug therapy is not the standard treatment for pernicious anemia after a gastrectomy. Pernicious anemia is primarily caused by vitamin B12 deficiency due to the absence of intrinsic factor, which is essential for vitamin B12 absorption.
Choice B rationale:
IV therapy is a broad term and does not specify the treatment for pernicious anemia. In the context of pernicious anemia, cobalamin replacement therapy administered via intramuscular injections is the preferred treatment.
Choice C rationale:
Quadruple-drug therapy is not a recognized treatment for pernicious anemia. The primary treatment for pernicious anemia involves cobalamin replacement therapy to address the vitamin B12 deficiency.
Choice D rationale:
Cobalamin replacement therapy is the appropriate treatment for pernicious anemia after a gastrectomy. Since the patient lacks intrinsic factor, which is necessary for vitamin B12 absorption, cobalamin replacement therapy bypasses the need for intrinsic factor and provides the necessary vitamin B12 directly.
