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","B"]
Explanation
Choice A rationale:
Anemia is not a direct manifestation of target organ damage from hypertension.
Choice B rationale:
Aneurysm is a correct answer. Persistent high blood pressure can weaken the walls of arteries, making them more susceptible to forming an aneurysm. Aneurysms can occur in various arteries, such as the aorta, and can lead to life-threatening complications if they rupture.
Choice C rationale:
Proteinuria is also a correct answer. Hypertension can damage the kidneys, leading to proteinuria, the presence of excess proteins in the urine. This is an indication of kidney damage and is a common manifestation of hypertensive target organ disease.
Choice D rationale:
Pneumonia and Transient Ischemic Attack (TIA) are not direct manifestations of target organ damage from hypertension.
Correct Answer is B
Explanation
Choice A rationale:
The base does interact with acids in the acid-base balance. Bases, by definition, are substances that can accept hydrogen ions (protons) and neutralize acids. In the context of acid-base balance, bases help regulate the pH of body fluids by counteracting the effects of acids.
Choice B rationale:
The role of the base in the acid-base balance is to promote the excretion of acid. Bicarbonate ions (HCO3-) are a vital component of the body's buffering system, helping to neutralize excess acid. The kidneys play a crucial role in excreting acids from the body, maintaining the acid-base balance.
Choice C rationale:
The base does not activate the system of acid-base balance; instead, it is part of the body's natural buffering system. The acid-base balance is regulated by the lungs and kidneys, which work together to maintain the pH of body fluids within a narrow range (7.35-7.45)
Choice D rationale:
Bases do not increase the action of hydrogen ions. In fact, bases neutralize hydrogen ions, which are acidic. By accepting these ions, bases help to decrease the acidity of a solution, playing a key role in maintaining the body's acid-base balance.
