To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client’s caregivers?

Choice A: Syncope

Reason: Syncope, or fainting, is a temporary loss of consciousness typically caused by a drop in blood flow to the brain. The client has a history of symptomatic bradycardia, which is a slow heart rate that can lead to insufficient blood flow and oxygen to the brain, causing syncope. The client reported passing out once due to a low heart rate, which aligns with the symptoms of syncope. Bradycardia can cause a significant drop in cardiac output, leading to decreased cerebral perfusion and resulting in fainting episodes.

Choice B: Hypovolemic Shock

Reason: Hypovolemic shock occurs when there is a significant loss of blood or fluids, leading to decreased blood volume and inadequate tissue perfusion. Symptoms include rapid heartbeat, low blood pressure, and confusion. However, the client’s history and current condition do not indicate any significant blood or fluid loss. The primary issue is related to the heart’s electrical activity and rate, not volume loss.

Choice C: Heart Failure

Reason: Heart failure is a condition where the heart cannot pump blood effectively, leading to symptoms like shortness of breath, fatigue, and fluid retention. While the client has a history of atrial fibrillation, which can contribute to heart failure, the immediate concern is the symptomatic bradycardia causing syncope. The client’s symptoms of low heart rate and fainting are more directly related to bradycardia rather than heart failure.

Choice D: Adverse Drug Reaction

Reason: An adverse drug reaction could cause various symptoms, including changes in heart rate and blood pressure. However, the client has not reported any new medications or changes in her current regimen that would suggest an adverse reaction. The symptoms described are consistent with her known condition of bradycardia.

Choice A: Anxiety

Reason: Anxiety can cause various physiological responses, including increased heart rate and blood pressure. However, the client’s primary issue is a low heart rate, which is not typically associated with anxiety. Anxiety might exacerbate symptoms but is not the root cause of the blood pressure changes in this case.

Choice B: Antibiotic

Reason: While antibiotics can cause side effects, they are not typically associated with significant changes in blood pressure. The vancomycin administered was for endocarditis prophylaxis and is unlikely to be the cause of the blood pressure changes observed.

Choice C: IV Infiltration

Reason: IV infiltration occurs when IV fluids leak into the surrounding tissue, causing swelling, pain, and potential tissue damage. While this can cause localized issues, it is not typically associated with systemic blood pressure changes. The client’s symptoms are more consistent with a systemic issue related to her heart condition.

Choice D: Vasodilation

Reason: Vasodilation refers to the widening of blood vessels, which can lead to a drop in blood pressure. This can occur as a response to various factors, including medications, heat, or a physiological response to low blood flow. In the context of bradycardia, the body’s compensatory mechanisms might include vasodilation to improve blood flow, which can result in lower blood pressure.

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.
