A nurse is assessing a client who is receiving a unit of packed red blood cells. Which of the following findings is a manifestation of acute hemolytic reaction?

The Correct answer is A.

Choice A reason: Evaluating the client for nausea, vomiting, and anorexia is important because these are common signs of digoxin toxicity. Digoxin is a cardiac glycoside used to treat heart failure and certain arrhythmias, but it has a narrow therapeutic window. Toxicity can occur due to various factors, including renal insufficiency or drug interactions. Monitoring gastrointestinal symptoms like nausea, vomiting, and loss of appetite can help detect toxicity early.

Choice B reason: Withholding digoxin if the heart rate is above 100/min is not typically recommended. Digoxin has a negative chronotropic effect, meaning it can decrease heart rate. However, the decision to withhold medication usually depends on a heart rate that is too low (bradycardia), not high. The normal range for resting heart rate in adults is 60-100 beats per minute. Therefore, withholding digoxin for a heart rate above 100/min without other clinical justifications would not be appropriate.

Choice C reason: Measuring the apical pulse rate for 30 seconds before administration is not the standard practice. The apical pulse should be measured for a full minute to ensure accuracy, especially in clients with heart failure who are receiving digoxin. This is because digoxin can cause arrhythmias, and a shorter measurement period may not provide a true representation of the heart's rhythm.

Choice D reason: Instructing the client to eat foods that are low in potassium is incorrect. Clients taking digoxin should maintain a normal potassium level, as hypokalemia can increase the risk of digoxin toxicity. The normal serum potassium level is 3.5-5.0 mEq/L. Foods high in potassium can help maintain this balance and should not be avoided unless there is a specific clinical indication, such as hyperkalemia.

Choice A reason: This is incorrect because dextrose 5% in 0.45% sodium chloride is a hypotonic solution that can cause hemolysis of the RBCs. It can also cause fluid shifts from the intravascular to the intracellular space, leading to edema and hypotension.

Choice B reason: This is correct because 0.9% sodium chloride is a isotonic solution that is compatible with blood products. It does not cause hemolysis or fluid shifts and maintains the osmotic pressure of the blood.

Choice C reason: This is incorrect because lactated Ringer's solution is a isotonic solution that contains electrolytes, such as potassium, calcium, and lactate, that can interfere with the blood products. It can also cause metabolic alkalosis due to the conversion of lactate to bicarbonate.

Choice D reason: This is incorrect because dextrose 5% in water is a hypotonic solution that can cause hemolysis of the RBCs. It can also cause fluid shifts from the intravascular to the intracellular space, leading to edema and hypotension.
