The nurse is caring for a client immediately following the insertion of a permanent pacemaker. Which intervention should be included in the plan of care?

Teach the client how to change the pacemaker dressing

Immobilize the affected arm using a sling

Arrange for ancillary personnel to feed the client

Monitor urine output every two hours

Answer and Explanation

The Correct Answer is B

A. Teach the client how to change the pacemaker dressing: Client education is important but not a priority in the immediate post-procedure phase. Dressing changes should initially be performed using sterile technique by clinical staff to prevent infection at the insertion site.

B. Immobilize the affected arm using a sling: After pacemaker insertion, the affected arm (usually on the side of the implantation) should be immobilized or limited in movement to prevent lead dislodgment. Elevating the arm above the shoulder or excessive motion can compromise pacemaker lead placement during the early healing period.

C. Arrange for ancillary personnel to feed the client: Assistance with feeding is only necessary if the client has physical or cognitive limitations. This is not a routine or priority intervention following pacemaker insertion unless clinically indicated by other assessments.

D. Monitor urine output every two hours: Frequent monitoring of urine output is not directly related to pacemaker insertion unless there are other concerns such as fluid imbalance or renal dysfunction. It's not a standard intervention in the immediate care plan for this procedure.

Correct Answer is D

Explanation

A. Blood pressure reading of 120/80: While a normal blood pressure is desirable, this value alone does not indicate improvement in fluid overload or pulmonary symptoms. It may remain normal even if respiratory status worsens or fails to improve.

B. Urine output 30 mL for one hour: Although urine output is an important measure of diuretic effectiveness, 30 mL/hr is the minimum acceptable rate, not necessarily a strong indicator of clinical improvement. More robust diuresis may be expected following IV furosemide.

C. Serum sodium level is 135 mEq/L (135–145): A normal sodium level reflects stable electrolyte status but does not directly indicate improvement in pulmonary congestion or dyspnea. Sodium may be affected by many factors unrelated to heart failure symptom relief.

D. Respiratory rate 16 per minute: A decrease in respiratory rate from 26 to 16 suggests improved oxygenation, reduced pulmonary congestion, and decreased work of breathing. It is the most direct and clinically relevant indicator of symptomatic improvement in this context.

A. Dehydration B. Infection C. Renal insufficiency D. internal bleeding

Correct Answer is A

Explanation

A. Dehydration: The elevated hemoglobin (17 g/dL) and hematocrit (54%), along with an increased BUN (28 mg/dL) and normal creatinine, suggest hemoconcentration, a key indicator of dehydration. Small bowel obstruction often leads to fluid loss through vomiting and third spacing into the bowel, contributing to this condition.

B. Infection: The WBC count is normal at 8.5, which does not support an active infection. Infections typically result in leukocytosis (WBC >10.5), especially in acute abdominal conditions.

C. Renal insufficiency: Although BUN is elevated, creatinine remains normal (1.1 mg/dL). This pattern, particularly with hemoconcentration, supports pre-renal azotemia due to dehydration, not intrinsic renal insufficiency.

D. Internal bleeding: Internal bleeding typically causes a decrease in hemoglobin and hematocrit due to blood loss. The elevated values in this case rule out active bleeding and instead indicate fluid volume deficit.
