1. Which of the following medications should be held 24-48 hours prior to an electroencephalogram (EEG)?

Correct answer: D

Rationale: Anticonvulsants like Dilantin should be held 24-48 hours before an EEG to prevent interference with the test results. Medications such as tranquilizers, barbiturates, and other sedatives should also be avoided. Lasix, Cardizem, and Lanoxin do not belong to these categories and are not known to interfere with EEG results.

2. What is the term for the tendency of a drug to combine with its receptor?

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

3. Which of these would be the most appropriate way to document a client's refusal of medication?

Correct answer: C

Rationale: The most appropriate way to document a client's refusal of medication should include details such as the medication, the client's statement of refusal, and the review of potential risks. Choice C accurately captures all these essential elements, making it the correct answer. Choice A lacks details about the client's refusal and the review of risks. Choice B includes unnecessary emotional descriptions and a plan of action that might not be appropriate. Choice D uses abbreviations that may not be universally understood, lacks proper punctuation, and also does not provide a detailed account of the refusal and the review of risks.

4. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?

Correct answer: A

Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.

5. The nurse is working the same shift two days in a row. On the first of these days, while caring for one assigned client, the client says, "Will you promise me you will be my nurse tomorrow?"? Which response is most appropriate?

Correct answer: D

Rationale: The most appropriate response is to maintain confidentiality regarding work assignments. It is crucial to uphold patient privacy and not disclose information about staff schedules or assignments. Choices A, B, and C involve promising or redirecting the patient, which is not suitable in this situation. Choice D respects confidentiality and is the most professional response in this scenario.
