Which of the following post-surgical clients warrant an immediate follow up by the nurse? (Select all that apply.)

Patient with lung surgery has 20 ml/hr of urine output via catheter.

Patient with appendix surgery has thready pulse and blood pressure is 90/60.

Patient with knee surgery has approximated incision.

Patient with femoral artery surgery has strong pedal pulse.

Patient with bladder surgery has bloody urine within the first 12 hours.

Answer and Explanation

Correct Answer : A,B,E

A.   A urine output of 20 ml/hr is considered inadequate and may indicate decreased kidney perfusion or function. This client likely needs immediate assessment and intervention to address potential renal complications.
B.   A patient with appendix surgery exhibiting a thready pulse and a blood pressure of 90/60 should be followed up immediately, as these signs can indicate shock, which is a medical emergency.
C.   An approximated incision indicates that the wound edges are well-aligned and healing is progressing as expected. This does not typically warrant immediate follow-up unless there are signs of infection or other complications.
D.   A strong pedal pulse suggests adequate blood flow distal to the surgical site. This is a positive finding and does not typically require immediate follow-up unless there are signs of vascular compromise or other complications.
E.   A patient with bladder surgery having bloody urine within the first 12 hours can be expected, but if the bleeding is heavy or increases, it would warrant immediate follow-up.

Correct Answer is D

Explanation

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.

A. Hemoglobin B. Creatinine C. Blood urea nitrogen D. Potassium

Correct Answer is A

Explanation

A. Hemoglobin levels are important for assessing oxygen-carrying capacity of the blood. While anemia can affect tissue oxygenation and exacerbate symptoms in heart failure, it is not directly related to the risk of digoxin toxicity.
B. Creatinine levels are used to assess kidney function. Impaired kidney function can affect the clearance of digoxin from the body, potentially increasing the risk of toxicity. However, potassium levels have a more direct impact on the risk of digoxin toxicity.
C. BUN levels are also used to assess kidney function. Similar to creatinine, impaired kidney function can affect digoxin clearance, but potassium levels are more directly related to the risk of digoxin toxicity.
D. Potassium levels are critical because hypokalemia (low potassium) can predispose the client to digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in cardiac cells. When potassium levels are low, digoxin can bind more readily to these pumps, leading to increased toxicity and potentially life-threatening arrhythmias such as ventricular tachycardia or ventricular fibrillation.
