Correct Answer: B

Rationale: The most important instruction for a female client diagnosed with trichomoniasis is to treat sexual partner(s) concurrently. This is crucial to prevent reinfection and the spread of the infection. Choice A, avoiding douching, is generally recommended for vaginal health but is not the most critical instruction in this case. Choice C, avoiding moist washcloths when bathing, is not directly related to the transmission or treatment of trichomoniasis. Choice D, postponing pregnancy until the infection is treated, is important but treating sexual partners concurrently takes precedence to prevent reinfection.

Correct Answer: A

Rationale: The correct answer is to assess the need for continued restraint. This is the most important nursing intervention as it ensures the client's safety and autonomy. Checking for urinary incontinence (Choice B) may be important but is not the priority in this situation. Determining skin integrity under the vest (Choice C) is essential but not as crucial as assessing the need for continued restraint. Performing range-of-motion exercises (Choice D) is important for client mobility but not the priority when a restraint is in place.

Correct Answer: B

Rationale: Visualization techniques, such as visualizing himself driving each route to the freeway, are commonly used in desensitization therapy to help clients gradually overcome their fears. Watching videos of others driving or taking medication do not actively involve the client in facing their fear, which is essential in desensitization therapy. Getting in the car with a support person during rush hour may exacerbate the client's anxiety rather than help in desensitization.

Correct Answer: D

Rationale: Gentle massage at the level of the umbilicus is the initial intervention to help contract the uterus and reduce bleeding, which is crucial in managing postpartum hemorrhage. Emptying the bladder can help with fundal displacement, but massage should be done first to stimulate uterine contractions. Increasing the IV oxytocin rate is a possible intervention but not the initial priority. Assessing for shock is important, but addressing the uterine atony through massage takes precedence to prevent further hemorrhage.

Correct Answer: D

Rationale: In the oliguric phase of acute renal failure (ARF), the goal is to prevent fluid overload. Since the client has a low urine output of 400 ml in 24 hours, limiting oral intake to 900 to 1,000 ml is appropriate. Encouraging unrestricted oral fluids (Choice A) can exacerbate fluid overload. Decreasing oral intake to 200 ml (Choice B) would be too restrictive and may lead to dehydration. Allowing the client to have exactly 400 ml oral intake (Choice C) would not account for other sources of fluid intake and output, potentially resulting in fluid imbalance.
