Correct Answer: A

Rationale: Proper surgical hand-washing technique involves keeping the hands higher than the elbows to prevent contamination. Washing with hands held lower than the elbows can lead to potential contamination. Using a brush to scrub under the nails is not recommended as it can cause microabrasions, increasing infection risk. While washing for at least 30 seconds is a good practice for thorough hand hygiene, hand positioning is critical during surgical hand-washing. Using alcohol-based hand rub alone is insufficient for surgical hand-washing as it may not effectively remove dirt, debris, and transient microorganisms.

Correct Answer: C

Rationale: The correct answer is to avoid taking antacids within 2 hours of phenytoin. Antacids can interfere with the absorption of phenytoin, reducing its effectiveness. Choice A is incorrect because phenytoin should not be taken with milk, as it may decrease its absorption. Choice B is unrelated to the medication and focuses on dental hygiene. Choice D is important but not directly related to phenytoin; it is more relevant to monitoring for adverse effects of the medication.

Correct Answer: C

Rationale: The correct answer is C because an ethical dilemma involves conflicting moral principles. In this scenario, the family's request not to disclose the terminal diagnosis to the client raises the moral question of truth-telling and patient autonomy. Choice A does not present an ethical dilemma but rather a challenge in client compliance. Choice B involves professional responsibility and accountability, not an ethical dilemma. Choice D relates to financial concerns and insurance coverage, which do not constitute an ethical dilemma but rather a financial issue.

Correct Answer: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

Correct Answer: B

Rationale: The correct answer is B. Going to the nurses' station for assistance during a seizure is inappropriate as immediate care is necessary. Placing the client on their side helps maintain an open airway and prevents aspiration. Noting the time the seizure begins is crucial for monitoring and documentation. Preparing to insert an airway may be necessary if the client's airway becomes compromised. Therefore, the nurse's statement about going to the nurses' station for assistance is the only incorrect response as it delays essential care.
