A nurse is caring for a client following a synchronized cardioversion. Which of the following findings indicates a therapeutic response to the treatment?

Weak peripheral pulses on palpation.

Cardiac monitor indicates sinus rhythm.

Diminished breath sounds on auscultation.

Pacer spikes precede the QRS complex on the ECG tracing.

Answer and Explanation

The Correct Answer is B

Rationale:

A. Weak peripheral pulses on palpation: Weak peripheral pulses can indicate poor circulation or low cardiac output, which is not a therapeutic response to synchronized cardioversion. The goal is to restore a normal rhythm and improve perfusion.

B. Cardiac monitor indicates sinus rhythm: Sinus rhythm on the cardiac monitor indicates that the cardioversion was successful in restoring a normal heart rhythm, making this the therapeutic response. This is the desired outcome after synchronized cardioversion.

C. Diminished breath sounds on auscultation: Diminished breath sounds are more indicative of respiratory issues, such as fluid in the lungs or atelectasis, and are not related to the effectiveness of synchronized cardioversion.

D. Pacer spikes precede the QRS complex on the ECG tracing: Pacer spikes are seen in patients with a pacemaker, not typically following synchronized cardioversion. If pacer spikes are seen, it indicates that pacing is occurring, which may be necessary in some situations, but it is not a sign of the success of cardioversion.

Correct Answer is ["A","B","C","F"]

Explanation

Rationale:

A. Renal failure: The client has elevated creatinine levels (1.7 mg/dL), which suggests kidney impairment. This could be due to dehydration and osmotic diuresis associated with hyperglycemia, which is commonly seen in diabetic ketoacidosis (DKA) or hyperglycemic-hyperosmolar state (HHS).

B. Hypotension: The client’s blood pressure is low (96/65 mm Hg), which can be attributed to dehydration caused by excessive urination and hyperglycemia. Hypotension can worsen as the client becomes more dehydrated, potentially progressing to shock.

C. Cerebral edema: Cerebral edema is a rare but serious complication of diabetic ketoacidosis (DKA), particularly in younger patients and those with severe electrolyte imbalances. The rapid correction of hyperglycemia can cause osmotic shifts that may lead to cerebral edema. The client’s altered fluid balance increases this risk.

D. Septic shock: Although the client has a history of bronchitis and pneumonia, there is no evidence of active sepsis at this time. Septic shock is characterized by signs of infection, such as fever and widespread infection leading to organ dysfunction. This client’s symptoms point more toward a metabolic complication rather than sepsis.

E. Respiratory alkalosis: Respiratory alkalosis occurs when there is excessive loss of carbon dioxide due to hyperventilation. In this client, there is no indication of Kussmaul respirations to suggest respiratory alkalosis. The client is more likely to develop metabolic acidosis due to the presence of ketones and a low pH (7.30).

F. Cardiac arrhythmias: Elevated potassium levels (5.5 mEq/L) and the potential for rapid fluctuations in electrolytes in a client with DKA or HHS can increase the risk of cardiac arrhythmias. Potassium imbalances hyperkalemia or hypokalemia, are closely linked to arrhythmias.

A. Bilateral lung crackles B. 1+ pitting peripheral edema C. Engorged neck veins D. Urine output 25 mL/hr

Correct Answer is D

Explanation

Rationale:

A. Bilateral lung crackles: Bilateral lung crackles are typically a sign of fluid overload or pulmonary edema, not fluid loss. They do not indicate the need for fluid resuscitation in the case of burns.

B. 1+ pitting peripheral edema:1+ pitting edema is mild and does not typically indicate the need for fluid resuscitation. It may occur with minor fluid retention, but it is not a severe indication of dehydration or fluid loss that would require resuscitation.

C. Engorged neck veins: Engorged neck veins suggest fluid overload or venous congestion, often seen in conditions like heart failure, but not in the immediate need for fluid resuscitation for burn patients.

D. Urine output 25 mL/hr: A urine output of 25 mL/hr is below the normal range (30 mL/hr or more) and suggests inadequate renal perfusion. This is a clear indicator that the client may require fluid resuscitation to restore adequate circulation and kidney function.
