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 B

Explanation

Rationale:

A. Apply a sequential compression device: A sequential compression device (SCD) is used to prevent deep vein thrombosis (DVT), not foot drop. It does not provide the necessary support for preventing foot drop, which results from muscle weakness or paralysis after a CVA.

B. Use padded splints: Padded splints help maintain the foot in a neutral position, which is essential in preventing foot drop. Foot drop occurs due to weakness of the dorsiflexor muscles, and splints can prevent the foot from falling into an abnormal position, reducing the risk of deformities.

C. Elevate the extremity above the heart: Elevating the extremity above the heart is typically done to reduce edema, not to prevent foot drop. While elevating the limb can help with swelling, it does not address the muscle weakness that causes foot drop in post-CVA patients.

D. Reposition the client every 2 hr: Repositioning the client every 2 hours is important for preventing pressure ulcers and promoting circulation. However, it is does not prevent foot drop, which requires targeted interventions such as splints or exercises to maintain proper foot positioning.

A. Photosensitivity B. Blurred vision C. Diarrhea D. Hypoglycemia

Correct Answer is C

Explanation

Rationale:

A. Photosensitivity: Photosensitivity is a known side effect of some antibiotics, particularly tetracyclines, but it is not commonly associated with cefaclor. The nurse should monitor for other more likely adverse effects of cefaclor.

B. Blurred vision: Blurred vision is not a typical side effect of cefaclor. Although some antibiotics may cause visual disturbances, this is not commonly seen with cefaclor, and there is no evidence linking cefaclor to blurred vision.

C. Diarrhea: Diarrhea is a common side effect of cefaclor, as it can disrupt the normal balance of gut bacteria. Antibiotics like cefaclor can cause gastrointestinal disturbances, including diarrhea, due to the killing of both harmful and beneficial bacteria in the intestines.

D. Hypoglycemia: Hypoglycemia is not a typical side effect of cefaclor. Although some medications can lower blood sugar, cefaclor is not generally associated with causing hypoglycemia, making this less relevant for monitoring in a client receiving cefaclor.
