A nurse is reviewing the medical record of a client who has a new prescription for verapamil. Which of the following findings in the client's medical record should the nurse identify as a contraindication for the administration of verapamil?

A. Intake and output: Monitoring intake and output is essential in the postoperative care of a client to assess fluid balance and kidney function. However, it is not the priority assessment when the client has received isoflurane in the PACU. The priority assessment in this situation is related to the potential cardiovascular side effect of isoflurane, which is hypotension. Hypotension can have immediate and significant implications for the client's perfusion and overall well-being, requiring prompt attention and intervention.

B. Non-verbal pain cues: Assessing for pain is important in the postoperative period to ensure adequate pain management and comfort for the client. However, it is not the priority assessment when the client has received isoflurane in the PACU. The priority assessment at this time is related to the potential cardiovascular impact of the anesthesia, which is blood pressure. Addressing hypotension takes precedence over pain assessment as it poses a more immediate threat to the client's well-being.

C. Bowel sounds: Assessing bowel sounds is part of a comprehensive postoperative assessment to monitor the return of bowel function after surgery. While it is important, it is not the priority assessment when the client has received isoflurane in the PACU. The priority assessment in this situation is related to the potential cardiovascular side effect of the anesthesia, which is blood pressure. Monitoring and managing hypotension is of greater concern in the immediate postoperative period.

D. Blood pressure: This is the correct answer. The priority assessment for a client who received isoflurane in the PACU is the blood pressure. Isoflurane is an inhalation anesthetic that can cause hypotension (low blood pressure). Monitoring the client's blood pressure is crucial to promptly identify and address any hypotension, as it can lead to inadequate tissue perfusion and oxygenation. Addressing blood pressure deviations is essential for the client's cardiovascular stability and overall recovery in the PACU.

Neostigmine is a medication classified as an acetylcholinesterase inhibitor. It is commonly used to treat myasthenia gravis and to reverse the effects of non-depolarizing neuromuscular blocking agents used during surgery. Adverse reactions to neostigmine are related to its cholinergic effects, which result from increased acetylcholine levels in the body.

Let's go through the options:

A. Hypoactive bowel sounds: Neostigmine can actually increase gastrointestinal motility and may cause increased bowel sounds or even diarrhea, not hypoactive bowel sounds. Therefore, hypoactive bowel sounds are not an adverse reaction to neostigmine.

B. Sweating: Sweating is a cholinergic effect and can be an adverse reaction to neostigmine. Increased sweating is a common sign of cholinergic stimulation.

C. Respiratory distress: Respiratory distress can occur as an adverse reaction to neostigmine, particularly if the client has a history of asthma or other respiratory conditions. Neostigmine can cause bronchoconstriction and excessive secretions, leading to respiratory distress.

D. Urinary retention: Neostigmine is actually used to treat urinary retention by increasing bladder contraction. Therefore, urinary retention is not an adverse reaction to neostigmine.

E. Bradycardia: Bradycardia (slow heart rate) is a significant adverse reaction to neostigmine due to its cholinergic effects on the heart. Increased acetylcholine levels can lead to excessive stimulation of the vagus nerve, resulting in bradycardia.
