A nurse in an emergency department is caring for a client who has a closed head injury. Which of the following actions should the nurse take first?

The correct answer is choice A. The nurse should compare new prescriptions with the list of medications the client reports. This is part of the medication reconciliation process, which is done to avoid medication errors such as omissions, duplications, dosing errors, or drug interactions. It should be done at every transition of care in which new medications are ordered or existing orders are rewritten.

Choice B is wrong because the nurse should not encourage the client to make his own list after he returns to his home. The nurse should provide the client with an updated and accurate list of medications before discharge and instruct the client to keep it with him at all times.

Choice C is wrong because the nurse should not include any adverse effects of the medications the client might develop. The nurse should include any known allergies or adverse reactions the client has experienced in the past, but not potential adverse effects that have not occurred.

Choice D is wrong because the nurse should not exclude nutritional supplements from the list of medications the client reports. The nurse should include all prescription medications, herbals, vitamins, nutritional supplements, over-the-counter drugs, vaccines, diagnostic and contrast agents, radioactive medications, parenteral nutrition, blood derivatives, and intravenous solutions in the medication reconciliation process.

Some of these products may interact with prescribed medications or affect laboratory results.

The correct answer is choice D. Shuffling gait. This is because shuffling gait is a common manifestation of pseudoparkinsonism, which is a condition that mimics the symptoms of Parkinson’s disease due to the use of certain medications that block dopamine receptors, such as haloperidol. Pseudoparkinsonism can cause slowed movements, muscle stiffness, tremor, and postural instability.

Choice A. Nonreactive pupils is wrong because this is not a typical feature of pseudoparkinsonism or Parkinson’s disease.

Nonreactive pupils can be caused by other conditions, such as brain injury, drugs, or eye diseases.

Choice B. Serpentine limb movement is wrong because this is a characteristic of tardive dyskinesia, another drug-induced movement disorder that can result from long-term use of dopamine receptor blocking agents. Tardive dyskinesia causes involuntary movements of the face, tongue, and limbs that are often writhing or twisting.

Choice C. Smacking lips is wrong because this is also a sign of tardive dyskinesia, not pseudoparkinsonism. Smacking lips is one of the orofacial movements that can occur in tardive dyskinesia due to abnormal muscle contractions.
