Correct Answer: A

Rationale: The correct answer is A: Decreased deep tendon reflexes. Magnesium sulfate toxicity can lead to diminished deep tendon reflexes, respiratory depression, and decreased urine output. Diminished deep tendon reflexes are an early sign of magnesium toxicity and indicate the need to discontinue the infusion. Elevated blood pressure (choice B) is not typically associated with magnesium toxicity. Increased urinary output (choice C) is also not a common finding in magnesium toxicity. Hyperreflexia (choice D) is not consistent with the expected findings of magnesium toxicity, which typically causes decreased reflexes.

Correct Answer: D

Rationale: The correct answer is D: Drink hot water with lemon juice each morning. Drinking hot water with lemon juice can help stimulate bowel movements, making it a natural and safe recommendation for pregnant clients experiencing constipation. Choice A is incorrect because reducing vitamin and supplement intake may not directly address constipation. Choice B, eating 15 g of fiber per day, could be helpful but may not be as effective as the correct answer for immediate relief. Choice C, consuming 48 ounces of water daily, is essential for overall health but may not be as directly effective as the correct answer in alleviating constipation.

Correct Answer: B

Rationale: The correct answer is B: 'Exercise for at least 30 minutes most days of the week.' Regular exercise, especially aerobic activity, is known to help lower blood pressure and should be included in lifestyle changes for managing hypertension. Choice A is incorrect because the recommended sodium intake for individuals with hypertension is usually lower than 3,000 mg per day. Choice C is incorrect as it is advisable to limit alcohol intake to one drink per day for women and two drinks per day for men. Choice D is incorrect because increasing fluid intake to 3 liters per day may not be necessary and could be harmful in some cases, depending on the individual's health status.

Correct Answer: B

Rationale: The correct answer is B because methadone typically causes sedation and respiratory depression, not trouble sleeping. The statement about trouble sleeping indicates a need for further teaching. Choices A, C, and D are incorrect because understanding that methadone slows breathing, avoiding alcohol while taking the medication, and changing positions slowly to prevent dizziness are all appropriate client statements when prescribed methadone.

Correct Answer: A

Rationale: Web-based applications are the most effective strategy for reaching young adults in the target group regarding safe sexual practices. Young adults today are highly engaged with mobile technology and the internet, making web-based applications the most accessible and convenient method to disseminate information. Print-based media like newspapers may not have the same reach and engagement among young adults. Television advertisements might reach a broader audience, but they may not be as targeted to the specific demographic of young adults. Brochures in kiosks in malls are less likely to reach a large number of young adults compared to web-based applications, which can be accessed anytime and anywhere through mobile devices.
