A client with nasal congestion receives a prescription for phenylephrine 10 mg PO every 4 hours. Which client condition should the nurse report to the healthcare provider before administering the medication?

The client is at immediate risk for developing Cardiac arrest, Anaphylaxis, and Arrhythmias.

Choice A: Peripheral Edema

Peripheral edema refers to the swelling of tissues, usually in the lower limbs, due to the accumulation of fluid. While peripheral edema can be a concern in patients with heart conditions, it is not an immediate risk in the context of the patient’s current situation. The primary concerns for this patient, given her history of symptomatic bradycardia and atrial fibrillation, are more acute and life-threatening conditions such as cardiac arrest, anaphylaxis, and arrhythmias. Peripheral edema is typically a chronic condition that develops over time and is not considered an emergent risk in this scenario.

Choice B: Renal Failure

Renal failure, or kidney failure, is a condition where the kidneys lose their ability to filter waste from the blood effectively. While renal failure can be a serious complication, it is not an immediate risk for this patient. The patient’s primary issues are related to her cardiovascular system, specifically her low heart rate and history of atrial fibrillation. The immediate risks in this scenario are more likely to be related to acute cardiovascular events rather than renal complications. Additionally, there is no indication in the patient’s history or current treatment that suggests an imminent risk of renal failure.

Choice C: Necrosis

Necrosis refers to the death of body tissue due to a lack of blood flow or infection. While necrosis can occur in severe cases of prolonged ischemia or infection, it is not an immediate risk for this patient. The patient’s current condition and treatment plan do not indicate a high risk of tissue necrosis. The more pressing concerns are related to her cardiovascular health, specifically the risk of cardiac arrest, anaphylaxis, and arrhythmias. These conditions are more likely to occur suddenly and require immediate medical intervention.

Choice D: Cardiac Arrest

Cardiac arrest is a sudden loss of heart function, leading to a cessation of blood flow to the body’s organs. Given the patient’s history of symptomatic bradycardia and atrial fibrillation, she is at a high risk of developing cardiac arrest. Bradycardia can lead to insufficient blood flow and oxygen delivery to vital organs, potentially resulting in cardiac arrest. Additionally, the stress of the upcoming procedure and the discontinuation of anticoagulants can further increase this risk. Therefore, cardiac arrest is a significant immediate risk for this patient and requires close monitoring and preparedness for emergency intervention.

Choice E: Anaphylaxis

Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur rapidly. The patient is receiving vancomycin, which is known to cause hypersensitivity reactions, including anaphylaxis, in some individuals. Symptoms of anaphylaxis include difficulty breathing, swelling, hives, and a drop in blood pressure. Given the patient’s current infusion of vancomycin, she is at risk for developing anaphylaxis, which requires immediate medical attention to prevent severe complications or death. The nurse must be vigilant for signs of anaphylaxis and be prepared to administer emergency treatment if necessary.

Choice F: Arrhythmias

Arrhythmias are irregular heartbeats that can range from benign to life-threatening. The patient has a history of atrial fibrillation, a type of arrhythmia, and symptomatic bradycardia, both of which put her at risk for developing further arrhythmias. The stress of the upcoming procedure, changes in medication, and the underlying heart conditions all contribute to the risk of arrhythmias. These irregular heartbeats can lead to decreased cardiac output, syncope, or even progression to more severe arrhythmias like ventricular fibrillation, which can be fatal. Therefore, arrhythmias are an immediate risk for this patient and require continuous cardiac monitoring and readiness to intervene.

Choice A Reason:

A digoxin level of 1.1 ng/mL is within the therapeutic range of 0.8 to 2.6 ng/mL. Therefore, this value does not require immediate reporting to the healthcare provider. Monitoring digoxin levels is important to avoid toxicity, but this specific level is considered safe.

Choice B Reason:

A potassium level of 3.2 mEq/L is below the normal range of 3.5 to 5.0 mEq/L. Hypokalemia (low potassium levels) can increase the risk of digoxin toxicity, as digoxin and potassium compete for the same binding sites on the Na+/K+ ATPase pump. Low potassium levels can enhance the effects of digoxin, leading to potentially dangerous cardiac arrhythmias. Therefore, this value should be reported immediately.

Choice C Reason:

A creatinine level of 0.8 mg/dL is within the normal range of 0.5 to 1.1 mg/dL. This value indicates normal kidney function, which is important for the excretion of digoxin. Therefore, this value does not require immediate reporting.

Choice D Reason:

A sodium level of 135 mEq/L is just below the normal range of 136 to 145 mEq/L. While slightly low, this value is not critically abnormal and does not pose an immediate threat. It should be monitored, but it does not require urgent reporting to the healthcare provider.
