The nurse has provided teaching to a client who had an implantable cardioverter/defibrillator inserted. Which statement by the client indicates the need for further instruction?

“I will be ready to resume participation in the football league in two weeks.!

'It is safe to use the microwave oven to heat up food."

“I can use my cellphone as long as I keep it 6 inches away from the device."

"The defibrillator will feel like a kick or blow to the chest if it fires."

Answer and Explanation

The Correct Answer is A

A.   This statement indicates a need for further education. After receiving an ICD, clients must refrain from engaging in vigorous physical activities such as contact sports (e.g., football) for a longer period of time to avoid injury or triggering the defibrillator. A longer recovery period is typically recommended.
B.   This is correct. Microwaves do not affect the function of an ICD, so it is safe to use one.
C.   This is correct. The client should keep their cellphone at least 6 inches away from the ICD to avoid interference with the device.
D.   This is correct. Clients may experience a sudden, forceful sensation similar to a kick or blow when the ICD delivers a shock to correct an arrhythmia.

Correct Answer is A

Explanation

A. INR = 3.7: The International Normalized Ratio (INR) is a measure of blood clotting. An INR greater than
3.0 indicates that the blood is not clotting properly, which can be caused by warfarin overdose. An elevated INR requires FFP to correct coagulopathy.
B. Hemoglobin = 6.3g/dL: This is low, indicating anemia, but it is not directly related to warfarin overdose. The primary issue here is coagulopathy, not anemia.
C. Fibrinogen = 90mg/dL: Fibrinogen levels may be decreased in various conditions, but this alone does not necessarily require additional FFP unless it’s below a critical threshold. Fibrinogen is not the main marker for warfarin overdose.
D. Platelets = 101,000 mm3: This platelet count is within the lower end of the normal range but does not indicate that more FFP is needed in response to warfarin overdose.

A. There is an increased risk for cardiac dysrhythmias B. There is dilutional hyponatremia and fluid retention C. There is an imbalance in the sodium-potassium pump D. The client is in acute renal failure related to heart failure

Correct Answer is B

Explanation

A. Increased risk for cardiac dysrhythmias: While hyponatremia can sometimes contribute to cardiac dysrhythmias, it's not the primary concern in this case. The main issue is fluid overload.
B. Hyponatremia, or low sodium levels, is often associated with heart failure. In this condition, the heart's reduced pumping ability leads to fluid retention, which dilutes the sodium concentration in the blood.
C. Imbalance in the sodium-potassium pump: While this can contribute to electrolyte imbalances, it's not the direct cause of hyponatremia in heart failure.
D. Acute renal failure: While heart failure can lead to acute kidney injury, hyponatremia is primarily a result of fluid overload rather than kidney dysfunction.
