A nurse is assessing a client who has fluid overload. Which of the following findings should the nurse expect? (Select all that apply)
Increased respiratory rate.
Increased heart rate
Increased blood pressure
Increased Hematocrit
Increased temperature
Correct Answer : A,B,C
Choice A: Increased Respiratory Rate
Fluid overload, also known as hypervolemia, can lead to an increased respiratory rate. This occurs because the excess fluid in the body can accumulate in the lungs, leading to pulmonary congestion and edema. As a result, the body attempts to compensate by increasing the respiratory rate to improve oxygenation and remove excess carbon dioxide. Normal respiratory rate for adults is typically between 12-20 breaths per minute. An increased respiratory rate above this range can indicate fluid overload.
Choice B: Increased Heart Rate
An increased heart rate, or tachycardia, is another common finding in clients with fluid overload. The heart has to work harder to pump the excess fluid throughout the body, leading to an increased heart rate. This is a compensatory mechanism to maintain adequate cardiac output and tissue perfusion. Normal resting heart rate for adults is between 60-100 beats per minute. A heart rate above this range can be indicative of fluid overload.
Choice C: Increased Blood Pressure
Fluid overload can also result in increased blood pressure, or hypertension. The excess fluid in the bloodstream increases the volume of blood that the heart has to pump, leading to higher pressure within the arteries. This can strain the cardiovascular system and lead to complications if not managed properly. Normal blood pressure is typically around 120/80 mmHg. Blood pressure readings consistently above this range can suggest fluid overload.
Choice D: Increased Hematocrit
Increased hematocrit is not typically associated with fluid overload. Hematocrit is the proportion of red blood cells in the blood. In cases of fluid overload, the hematocrit level is usually decreased due to the dilutional effect of the excess fluid. Therefore, this choice is incorrect.
Choice E: Increased Temperature
Increased temperature is not a common finding in fluid overload. Fever or elevated body temperature is more commonly associated with infections or inflammatory conditions. Fluid overload does not typically cause an increase in body temperature. Therefore, this choice is incorrect.

Correct Answer is A
Explanation
Choice A: Metformin
Metformin is known to interact with contrast material, particularly iodinated contrast media, and can increase the risk of acute kidney injury (AKI). This interaction can lead to a condition known as contrast-induced nephropathy (CIN) or contrast-induced acute kidney injury (CI-AKI). Metformin is primarily excreted by the kidneys, and impaired renal function can lead to its accumulation, increasing the risk of lactic acidosis, a rare but serious complication. Therefore, it is generally recommended to withhold metformin before and after the administration of contrast media until renal function is confirmed to be normal.
Choice B: Carvedilol
Carvedilol is a beta-blocker used to treat high blood pressure and heart failure. It does not have a known interaction with contrast media that would increase the risk of acute kidney injury. Carvedilol primarily affects the cardiovascular system and does not significantly impact renal function or interact with contrast agents.
Choice C: Nitroglycerin
Nitroglycerin is used to treat angina and other heart conditions by dilating blood vessels. It does not interact with contrast media in a way that would increase the risk of acute kidney injury. Nitroglycerin’s primary effects are on the cardiovascular system, and it does not have nephrotoxic properties.
Choice D: Atorvastatin
Atorvastatin is a statin used to lower cholesterol levels. While it can have effects on liver enzymes and muscle tissue, it does not interact with contrast media to increase the risk of acute kidney injury. Atorvastatin is metabolized by the liver and does not significantly impact renal function.
Correct Answer is C
Explanation
Choice A Reason:
Weigh the client daily: While monitoring weight is important for clients with Addison’s disease, it is not the primary action to prevent an Addisonian crisis. Daily weight monitoring helps track fluid balance and detect any sudden changes that might indicate complications, but it does not directly address the hormonal imbalance that characterizes Addisonian crisis.
Choice B Reason:
Restrict food intake: Restricting food intake is not recommended for clients with Addison’s disease. Proper nutrition is crucial for maintaining energy levels and overall health. Clients with Addison’s disease need a balanced diet to manage their condition effectively. Restricting food intake could lead to malnutrition and exacerbate symptoms.
Choice C Reason:
Administer oral corticosteroids: This is the correct action. Addison’s disease is characterized by insufficient production of cortisol and aldosterone by the adrenal glands. Administering oral corticosteroids helps replace the deficient hormones and manage the symptoms of Addison’s disease. During an Addisonian crisis, immediate administration of corticosteroids is critical to prevent severe complications such as shock, coma, or even death.
Choice D Reason:
Provide a low carbohydrate diet: A low carbohydrate diet is not specifically recommended for clients with Addison’s disease. Instead, a balanced diet that includes adequate carbohydrates, proteins, and fats is essential. Carbohydrates are important for maintaining energy levels, especially since clients with Addison’s disease may experience fatigue and weakness. Restricting carbohydrates could lead to low blood sugar levels, which can be dangerous for these clients.
