Which explanation will the nurse give a patient with non-Hodgkin lymphoma about the purpose of a planned lumbar puncture?

Choice A rationale:

Fullness from ascites is a symptom associated with conditions like liver cirrhosis, not directly related to chronic heart failure. Ascites is the accumulation of fluid in the abdominal cavity, causing a feeling of fullness and abdominal discomfort.

Choice B rationale:

Hypoproteinemia, a condition characterized by low levels of proteins in the blood, can lead to fluid retention and edema. However, it is not a direct cause of frequent urination. Frequent urination in this context is more likely related to increased fluid volume in the body, which can be caused by increased renal perfusion in the supine position due to fluid redistribution from the lower extremities to the kidneys.

Choice C rationale:

Hypoperfusion to the brain can lead to neurological symptoms, but it does not directly cause frequent urination. Frequent urination is often related to the kidneys' ability to filter excess fluid and excrete it as urine.

Choice D rationale:

Increased renal perfusion in the supine position can cause frequent urination, especially at night. When a person with chronic heart failure lies down, fluid that has accumulated in the lower extremities (edema) during the day is redistributed to the kidneys due to the change in body position. This increased renal perfusion results in an increased production of urine, leading to nocturia (frequent urination at night) and disrupting the patient's ability to sleep well. This symptom is characteristic of heart failure-related fluid overload and is an important clinical sign indicating worsening heart failure.

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.
