The nurse assesses the telemetry monitor of a client who is 24 hours postoperative from having a permanent pacemaker insertion. The nurse observes that a pacemaker spike is present before each QRS complex in lead II of the electrocardiogram (ECG). Which intervention should the nurse implement?

Document that the client is experiencing a paced rhythm.

Reposition the ECG leads and obtain another recording.

Assess the client for symptoms of decreased cardiac output.

Notify the healthcare provider (HCP) of the telemetry recording.

Answer and Explanation

The Correct Answer is A

A. Document that the client is experiencing a paced rhythm. A pacemaker spike before each QRS complex indicates that the pacemaker is functioning properly and triggering ventricular depolarization as intended. Since the client is 24 hours postoperative from a pacemaker insertion, this is an expected finding and should be documented accordingly.
B. Reposition the ECG leads and obtain another recording. If the ECG showed artifact, lead displacement, or interference, repositioning the leads might be appropriate. However, the presence of consistent pacemaker spikes before each QRS complex suggests proper pacemaker function rather than a lead issue.
C. Assess the client for symptoms of decreased cardiac output. A paced rhythm is expected after pacemaker insertion and does not necessarily indicate hemodynamic instability. While assessment is always important, there is no indication that the client is experiencing decreased cardiac output symptoms such as hypotension, dizziness, or altered mental status.
D. Notify the healthcare provider (HCP) of the telemetry recording. Routine paced rhythms do not require immediate provider notification unless there are malfunctions such as failure to capture, failure to sense, or failure to pace. Since the pacemaker is functioning appropriately, notifying the HCP is unnecessary.

Correct Answer is C

Explanation

A. Expel the excess air and heparin from the syringe. While removing excess air prevents gas exchange alterations, this is not the priority when obtaining an SVO₂ sample. Excess heparin could dilute the sample, but proper blood volume collection is the first concern.
B. Place sample in arterial blood gas syringe. SVO₂ measures venous oxygen saturation, which is different from arterial blood gases (ABGs). Using an ABG syringe is incorrect because it is heparinized for arterial sampling, and arterial blood does not reflect mixed venous oxygenation.
C. Obtain a minimum of 1 mL of blood. SVO₂ is measured from the distal lumen of a pulmonary artery (PA) catheter to assess oxygen delivery and consumption. At least 1 mL of blood is required for an accurate reading, ensuring sufficient sample volume for laboratory analysis.
D. Aspirate the blood sample slowly. While slow aspiration can help prevent hemolysis, it is not the primary concern when collecting an SVO₂ sample. The priority is obtaining a sufficient volume (≥1 mL) for an accurate measurement.

A. Hyperglycemia. B. Hypotension. C. Paralytic ileus and abdominal distention. D. Muscle twitching and digit numbness.

Correct Answer is D

Explanation

A. Hyperglycemia. While elevated blood glucose can occur in acute pancreatitis due to pancreatic inflammation impairing insulin secretion, it is not an electrolyte imbalance. The question specifically asks about electrolyte-related manifestations.
B. Hypotension. Hypotension in acute pancreatitis is often due to fluid shifts (third-spacing) and systemic inflammation, rather than a direct electrolyte imbalance. Though dehydration and electrolyte losses can contribute to hypotension, this is not the most specific sign of an electrolyte disturbance.
C. Paralytic ileus and abdominal distention. Hypokalemia can lead to paralytic ileus, but ileus and distention are also caused by peritoneal irritation, inflammation, and impaired motility due to pancreatitis itself. While potassium imbalance could contribute, this is not the most direct electrolyte-related symptom.
D. Muscle twitching and digit numbness. Hypocalcemia is a common electrolyte imbalance in acute pancreatitis, caused by fatty acid breakdown binding calcium, leading to saponification. This results in neuromuscular excitability, causing muscle twitching, paresthesia (numbness/tingling), and positive Chvostek’s or Trousseau’s signs. These symptoms are clear indicators of an electrolyte disturbance related to pancreatitis.
