The nurse is performing tracheostomy care for a client when a code blue is called for another client on the unit who experiences a cardiopulmonary arrest. Which action should the nurse take?

After retinal detachment surgery, it is crucial to protect the eye and the surgical repair site from accidental trauma or pressure. Providing an eye shield helps to shield the eye during sleep when the client may not have conscious control over their movements.

This can help prevent inadvertent rubbing or bumping of the eye, which could potentially disrupt the surgical repair and hinder the healing process.

Obtaining vital signs every 2 hours during hospitalization is a routine nursing intervention for postoperative care in general but is not specific to retinal detachment surgery. The frequency of vital sign monitoring may vary depending on the client's overall condition and the healthcare provider's orders.

Teaching a family member to administer eye drops may be necessary for the client's ongoing care, but it is not specifically related to the immediate postoperative period. Eye drop administration instructions can be provided as part of the client's discharge teaching.

Encouraging deep breathing and coughing exercises is a general postoperative intervention that promotes respiratory function and helps prevent complications such as pneumonia. While important for overall postoperative care, it is not specific to retinal detachment surgery.

The client's serum potassium level is elevated at 6.0 mEq/L (6.0 mmol/L), which is above the normal reference range of 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L).

Hyperkalemia can have significant cardiac implications, including the potential for life-threatening dysrhythmias. Therefore, close monitoring of the serum potassium level is crucial to assess the effectiveness of interventions and ensure that potassium levels are within a safe range.

While monitoring glucose levels before and after meals is important for clients receiving insulin therapy, in this scenario, the primary concern is the elevated potassium level.

The nurse should prioritize frequent assessment of the serum potassium level to guide appropriate management and prevent complications associated with hyperkalemia.

Monitoring and documenting strict intake and output are important for assessing fluid balance and renal function, but in this case, the elevated potassium level takes precedence as it poses a more immediate risk to the client's well-being.

Obtaining a 12-lead electrocardiogram (ECG) daily may be indicated in some cases of hyperkalemia, as certain ECG changes can be associated with elevated potassium levels. However, the more critical aspect is monitoring the potassium level itself, as ECG changes can occur rapidly and may not always be detectable on a daily basis.
