What is the initial goal for the treatment of secondary hypertension?
Administration of digoxin.
Weight control and diet.
Treating the underlying disease.
Administration of B-adrenergic receptor blockers.
The Correct Answer is C
The correct answer is choice C. Treating the underlying disease.
Choice A rationale:
Administration of digoxin. Administering digoxin is not the initial goal for the treatment of secondary hypertension. Digoxin is a medication commonly used to treat heart failure and certain arrhythmias, but it is not a primary intervention for hypertension. The rationale for this choice being incorrect lies in the fact that digoxin primarily affects the heart's contractility and is not a preferred option for managing high blood pressure.
Choice B rationale:
Weight control and diet. Weight control and dietary modifications are important aspects of managing hypertension, both primary and secondary. However, they are not the initial goal for the treatment of secondary hypertension. While these lifestyle modifications can contribute to blood pressure reduction, the primary focus in secondary hypertension is to identify and address the underlying condition causing the high blood pressure.
Choice C rationale:
Treating the underlying disease. Correct Answer. The initial goal for the treatment of secondary hypertension is to address the underlying disease or condition that is causing the elevated blood pressure. Unlike primary hypertension, which often lacks a specific underlying cause, secondary hypertension results from an identifiable condition such as kidney disease, hormonal disorders, or certain medications. Treating the root cause can lead to blood pressure normalization.
Choice D rationale:
Administration of β-adrenergic receptor blockers. Administering β-adrenergic receptor blockers is not typically the initial goal for the treatment of secondary hypertension. While these medications can lower blood pressure by blocking the effects of adrenaline and reducing heart rate, they are not the first-line approach for addressing the underlying cause of secondary hypertension.

Correct Answer is C
Explanation
The correct answer is choice C. Decreased oxygen-carrying capacity of blood.
Choice A rationale:
Anemia does not primarily result in a depressed hematopoietic system. In fact, anemia often occurs due to various factors that affect red blood cell production or lifespan. The hematopoietic system can be overactive in response to anemia, attempting to compensate for the reduced oxygen-carrying capacity of the blood.
Choice B rationale:
While some anemias may involve the presence of abnormal hemoglobin (e.g., sickle cell anemia), this is not the primary result of anemia. The primary consequence of anemia is a decreased ability of the blood to carry oxygen to the body's tissues.
Choice C rationale:
The correct choice. Anemia leads to a decreased oxygen-carrying capacity of the blood. Hemoglobin, the protein in red blood cells responsible for carrying oxygen, is reduced in quantity or function in various types of anemia. This results in inadequate oxygen delivery to tissues, potentially causing symptoms such as fatigue, weakness, pallor, and shortness of breath.
Choice D rationale:
Increased blood viscosity is not a primary result of anemia. Anemia tends to reduce blood viscosity because there are fewer red blood cells and less hemoglobin present, which makes the blood more fluid and less viscous. Increased blood viscosity is more commonly associated with conditions like polycythemia, where there is an excess of red blood cells.
Correct Answer is A
Explanation
The correct answer is choice A. Potassium.
Choice A rationale:
Diuretics like furosemide are commonly used to treat congestive heart failure. They work by increasing the excretion of water and electrolytes, including potassium, from the body. Low levels of potassium (hypokalemia) can lead to various complications, including cardiac arrhythmias and muscle weakness. Since furosemide can cause potassium loss, it's important to ensure an adequate intake of potassium-rich foods. Bananas, oranges, and leafy vegetables are excellent sources of potassium. Therefore, the nurse encourages the family to include these foods in the child's diet to help maintain a healthy potassium balance.
Choice B rationale:
Sodium is an important electrolyte, but in the context of congestive heart failure and diuretic use, the focus is more on avoiding excessive sodium intake. Diuretics like furosemide aim to reduce fluid retention by increasing sodium excretion, so it's not necessary to recommend high-sodium foods. Moreover, excessive sodium intake could exacerbate fluid retention and worsen the heart failure.
Choice C rationale:
Chlorides are often found in table salt (sodium chloride) and are not typically emphasized in the context of heart failure treatment or diuretic use. While they play a role in maintaining electrolyte balance, they are not the primary focus in this scenario.
Choice D rationale:
Zinc is a mineral that is not directly related to the treatment of congestive heart failure or the use of diuretics. It is important for various cellular functions and immune system support, but it's not the electrolyte of concern in this situation.
