Correct Answer: B

Rationale: The correct answer is 'false positive.' A false-positive result occurs when a test result is labeled positive in error, when the actual result is negative. In this scenario, the client received a positive test result incorrectly, as he does not have the disease being tested for. Choice A ('positive') is too vague and does not specify that the result was incorrect. Choice C ('negative') is the opposite of what happened in the scenario. Choice D ('false negative') refers to a situation where a test result is labeled negative incorrectly, which is not the case in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.

Correct Answer: A

Rationale: Clients with dumping syndrome should lie down after eating to decrease the symptoms of dumping syndrome, which include rapid gastric emptying leading to various gastrointestinal symptoms. On the other hand, clients with GERD should sit up at least 30 minutes after meals to prevent the backflow of stomach acid into the esophagus. This position helps reduce symptoms by allowing gravity to keep the stomach contents in place, minimizing the chances of reflux. Therefore, the correct answer is to lie down 1 hour after eating for dumping syndrome and to sit up at least 30 minutes after eating for GERD. Choices B, C, and D are incorrect because they do not accurately reflect the appropriate positioning for each condition.

Correct Answer: C

Rationale: Genital herpes can be transmitted through oral, genital, and anal sex. It's crucial to understand that the infection can be spread through intercourse even when symptoms are not present. Option A is incorrect because genital herpes is not transmitted through toilet seats. Option B is correct as oral sex can transmit the virus. Option D is incorrect as drinking fluids after sex does not prevent the transmission of genital herpes.

Correct Answer: B

Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.
