A nurse is collecting data from a client who has heart failure prior to the administration of furosemide. For which of the following findings should the nurse withhold the medication?

A.

Blood pressure of 80/40 mm/Hg

B.

Oxygen saturation of 95%

C.

Serum sodium level of 140 mEq/L

D.

Serum potassium level of 4.8 mEq/L

Answer and Explanation

The Correct Answer is A

A. A blood pressure of 80/40 mm/Hg indicates hypotension, which is a contraindication for administering furosemide. The medication can further lower blood pressure and increase the risk of adverse effects.  

 

B. An oxygen saturation of 95% is within normal limits and does not indicate a need to withhold furosemide.  

 

C. A serum sodium level of 140 mEq/L is normal and would not warrant withholding the medication.  

 

D. A serum potassium level of 4.8 mEq/L is also normal and safe for furosemide administration, as the medication may cause potassium loss but does not require withholding if the level is within range.

Correct Answer is B

Explanation

A. Primary progressive multiple sclerosis is characterized by a gradual progression of symptoms without relapses, so this does not match the client's pattern.

B. Relapsing-remitting multiple sclerosis is defined by episodes of exacerbation (active symptoms) followed by periods of remission (no symptoms), which aligns with the client's description.

C. Secondary progressive multiple sclerosis follows an initial relapsing-remitting course but leads to a more continuous decline in function, so it does not match the pattern described.

D. Clinically isolating syndrome refers to a single episode of neurological symptoms but does not indicate the pattern of relapses and remissions typical of relapsing-remitting multiple sclerosis.

Correct Answer is D

Explanation

A. While hyperlipidemia can contribute to vascular damage, it primarily increases the risk of cardiovascular disease and stroke, rather than directly blocking neuron communication to cause dementia.

B. Peptic ulcer disease is not associated with dementia, and the loss of nerve cells in the stomach does not lead to cognitive decline.

C. Peptic ulcer disease does not cause dementia by impacting neuron communication in the stomach.

D. Vascular dementia is often caused by stroke due to reduced blood flow or damage to the blood vessels in the brain, leading to cognitive decline and memory loss.
