A nurse is caring for a school-age child who is 2 hr postoperative following a cardiac catheterization.

The nurse observes blood on the child’s dressing.

Choice A reason:

Completing an incident report is not the correct action. An incident report should be completed as part of the hospital's protocol to document the medication error and ensure appropriate follow-up and investigation.

Choice B reason:

Checking the client for indications of bleeding is the correct action to be taken. In this situation, the nurse's first priority should be to assess the client for indications of bleeding, as the client received a significantly higher dose of IV heparin than prescribed. Heparin is an anticoagulant medication used to prevent blood clots, and an overdose can increase the risk of bleeding.

After administering the wrong dose of medication, the nurse's immediate concern is the client's safety and well-being. Checking for signs of bleeding, such as petechiae, ecchymosis, hematomas, bleeding gums, melena (black, tarry stools), haematuria (blood in urine), or any other unusual bleeding, is crucial.

Choice C reason:

Monitor the client's aPTT levels: This is not the correct action to be taken. Monitoring the client's activated partial thromboplastin time (aPTT) levels is essential to assess the client's coagulation status and determine if the overdose of heparin has affected their clotting ability. The healthcare provider may adjust the heparin dosage based on the aPTT levels.

Choice D reason:

Notify the risk manager: This is not the correct action to be taken. The risk manager or appropriate supervisor should be informed about the medication error as soon as possible to initiate a thorough review of the incident and take necessary steps to prevent similar errors in the future.

The correct answer is choice B, bradypnea. Bradypnea is abnormally slow breathing, which can be a sign of life-threatening respiratory depression caused by morphine. Respiratory depression is the most serious adverse effect of morphine and can lead to coma and death if not treated promptly. Therefore, the nurse should monitor the child’s respiratory rate and oxygen saturation closely and be prepared to administer naloxone, an opioid antagonist, if needed.

Choice A, euphoria, is wrong because euphoria is a feeling of intense happiness or well-being that is a common side effect of morphine.

Euphoria is not a priority finding and does not indicate a serious complication of morphine.

Choice C, constipation, is wrong because constipation is a common and chronic side effect of morphine that affects the gastrointestinal system.

Constipation can cause discomfort and complications such as bowel obstruction, but it is not a priority finding compared to respiratory depression.

Choice D, sedation, is wrong because sedation is another common side effect of morphine that affects the central nervous system.

Sedation can impair the child’s level of consciousness and ability to respond to stimuli, but it is not as urgent as respiratory depression.
