A nurse is caring for a client who has a high fever and is at risk for fluid volume deficit. The nurse should monitor the client for which of the following signs of fluid loss?

Choice A reason:

Muscle weakness is a symptom of hypokalemia, which is a low level of potassium in the blood. Potassium is an important electrolyte that helps regulate the function of the heart and muscles. Diuretics can cause potassium loss through increased urine output, which can lead to hypokalemia. Hypokalemia can affect the heart rhythm and cause muscle cramps, weakness, fatigue, and constipation. Therefore, the client should report muscle weakness to the provider as it may indicate a need for potassium supplementation or a change in diuretic therapy.

Choice B reason:

Nausea and vomiting are not specific symptoms of diuretic use or fluid and electrolyte imbalance. They can be caused by many other factors, such as infection, food poisoning, medication side effects, or psychological stress. Nausea and vomiting can also lead to dehydration and electrolyte imbalance if not treated promptly. Therefore, the client should drink plenty of fluids and seek medical attention if nausea and vomiting persist or are severe, but they are not directly related to diuretic use or heart failure.

Choice C reason:

Headache and blurred vision are not common symptoms of diuretic use or fluid and electrolyte imbalance. They can be caused by many other factors, such as high blood pressure, migraine, eye strain, or neurological disorders. Headache and blurred vision can also be signs of a serious condition, such as stroke or brain tumor, that requires immediate medical attention. Therefore, the client should report headache and blurred vision to the provider as soon as possible, but they are not directly related to diuretic use or heart failure.

Choice D reason:

Constipation and abdominal pain are not common symptoms of diuretic use or fluid and electrolyte imbalance. They can be caused by many other factors, such as dietary changes, lack of fiber, medication side effects, or bowel obstruction. Constipation and abdominal pain can also be signs of a serious condition, such as appendicitis or diverticulitis, that requires immediate medical attention. Therefore, the client should report constipation and abdominal pain to the provider as soon as possible, but they are not directly related to diuretic use or heart failure.

Choice A reason: Feeling thirsty all the time is a sign of dehydration, not fluid loss. Dehydration occurs when the body does not have enough water and other fluids to carry out its normal functions. Dehydration can be caused by excessive sweating, vomiting, diarrhea, fever, or decreased water intake.

Choice B reason:

Gaining 2 pounds since yesterday is a sign of fluid retention, not fluid loss. Fluid retention occurs when the body holds on to extra water and salt in the tissues or blood vessels. Fluid retention can be caused by heart failure, kidney disease, liver disease, hormonal changes, or certain medications.

Choice C reason:

Having trouble breathing when lying down is a sign of orthopnea, not fluid loss. Orthopnea is a condition where a person feels short of breath when lying flat. Orthopnea can be caused by heart failure, lung disease, obesity, or sleep apnea.

Choice D reason:

Feeling dizzy when standing up is a sign of orthostatic hypotension, which is a possible sign of fluid loss. Orthostatic hypotension is a condition where the blood pressure drops when changing position from lying or sitting to standing. This can cause dizziness, lightheadedness, or fainting. Orthostatic hypotension can be caused by hypovolemia, which is a decrease in the volume of blood in the body due to fluid loss. Fluid loss can occur from bleeding, vomiting, diarrhea, sweating, or burns.
