The nurse is caring for a client with a heart rate of 48. His blood pressure is 120/80. Which finding will help the nurse determine the cause of the client's bradycardia?

The client has a fever.

The client has possible hemorrhage or bleeding.

The client has chronic obstructive pulmonary disease (COPD).

The client has calcium channel blocker medicate prescribed.

Answer and Explanation

The Correct Answer is D

A.   Fever can cause tachycardia (increased heart rate) rather than bradycardia. It is not typically associated with slowing of the heart rate unless there are other complicating factors such as severe infection or medication side effects.
B.   Significant blood loss can lead to hypovolemia (low blood volume), which can result in bradycardia as a compensatory mechanism to maintain blood pressure. However, the blood pressure in this scenario is

normal (120/80), which makes severe hemorrhage less likely unless compensated by fluid resuscitation or other factors.
C.   COPD can cause chronic hypoxia and respiratory acidosis, which can lead to chronic respiratory compensation and potentially bradycardia. However, COPD alone is less likely to cause bradycardia in the absence of severe exacerbation or other complicating factors.
D.   Calcium channel blockers (CCBs) are medications commonly prescribed for conditions such as hypertension, angina, and arrhythmias. They work by blocking calcium channels in cardiac and smooth muscle cells, resulting in decreased heart rate and vasodilation. Bradycardia is a known side effect of CCBs, especially when taken in excess or in combination with other medications that affect heart rate.

Correct Answer is ["167"]

Explanation

1 kilogram is equivalent to 2.2 pounds.

The client weighs 245 lbs, which is approximately 111.36 kg (245 lbs / 2.2). The prescribed dosage is 1.5 mg per kilogram.

Therefore, the dosage per dose would be 1.5 mg/kg * 111.36 kg, which equals 167.04 mg. Rounded to the nearest whole number, the nurse should administer 167 mg per dose.

A. Hematocrit 40% B. Creatinine 0.9 mg/dL C. WBC count 20,000/mm3 D. Potassium 3.8 mEq/L

Correct Answer is C

Explanation

A. A hematocrit of 40% is within the normal range for females, which is typically around 37-47%. This result is not concerning and does not typically require immediate notification to the surgeon.
B. A creatinine level of 0.9 mg/dL is within the normal range for adults (normal range varies slightly among laboratories but is generally around 0.5-1.1 mg/dL). This result indicates normal kidney function and does not require immediate notification.
C. A white blood cell (WBC) count of 20,000/mm3 is elevated above the normal range, which is typically between 4,500-11,000/mm3. An elevated WBC count could indicate infection or inflammation. Given the client is preoperative, an elevated WBC count may suggest an underlying infection that needs to be addressed before proceeding with surgery. The nurse should notify the surgeon promptly so appropriate evaluation and management can be initiated.
D. A potassium level of 3.8 mEq/L is within the normal range (normal range is generally 3.5-5.0 mEq/L). This result is not concerning and does not require immediate notification to the surgeon.
