Correct Answer: C

Rationale: The correct answer is C: anticonvulsant. Magnesium sulfate is used in the treatment of preeclampsia to prevent seizures, making it an anticonvulsant. It works by reducing neuromuscular excitability and stabilizing nerve cell membranes. Choice A (diuretic) is incorrect because magnesium sulfate does not primarily promote diuresis. Choice B (tocolytic) is incorrect as it does not inhibit uterine contractions. Choice D (antihypertensive) is incorrect because although magnesium sulfate can help lower blood pressure in preeclampsia, its primary indication in this case is for seizure prophylaxis.

Correct Answer: B

Rationale: The correct answer is B: There is an increased incidence of disease. Low-income immigrants often face barriers to healthcare access, leading to higher rates of undiagnosed and untreated health conditions. This information is crucial for the nurse to plan appropriate care interventions. Incorrect choices: A: Decreased frequency of morbidity is not accurate as low-income immigrants may experience higher rates of illness due to lack of resources. C: Increased level of health is unlikely in this population due to socioeconomic factors affecting health outcomes. D: Decreased mortality rate is not supported as low-income immigrants may have higher mortality rates due to limited access to healthcare.

Correct Answer: C

Rationale: The correct answer is C: Work with the team to negotiate informed consent. In this scenario, the nurse should prioritize respecting the patient's cultural beliefs while also ensuring the patient's autonomy and right to make decisions about his own healthcare. By working with the healthcare team to negotiate informed consent, the nurse can involve both the patient and his eldest son in the decision-making process, ensuring that the patient's preferences are respected while also upholding ethical principles of patient autonomy and beneficence. This approach promotes collaboration and respect for cultural values while still safeguarding the patient's rights. Choice A is incorrect because it does not involve the patient in the decision-making process and could undermine his autonomy. Choice B is incorrect as it disregards the patient's cultural beliefs and preferences. Choice D is incorrect as it may violate the patient's right to information and involvement in his own care.

Correct Answer: B

Rationale: The correct answer is B: Contraction of bronchial smooth muscle. Histamine release can lead to bronchoconstriction, which narrows the airways and causes difficulty in breathing. This is a common symptom in allergic reactions like asthma. Constriction of small venules (Choice A) is not a typical consequence of histamine release. Dilation of large blood vessels (Choice C) is more associated with histamine's role in increasing vascular permeability. Decreased secretions from gastric and mucosal cells (Choice D) is not directly related to histamine's effects on smooth muscle contraction.

Correct Answer: C

Rationale: The correct answer is C: The need to perform thorough hand hygiene before handling the prosthesis. This is crucial to prevent infection. By washing hands thoroughly, the patient reduces the risk of introducing harmful bacteria or pathogens to the prosthesis, which could lead to infections or other complications. Incorrect Choices: A: The need to limit exposure to bright light - This is not directly related to caring for an ocular prosthesis. B: The need to maintain a low Fowlers position when removing the prosthesis - Positioning is not typically a concern when caring for an ocular prosthesis. D: The need to apply antiviral ointment to the prosthesis daily - Antiviral ointment is not a standard part of ocular prosthesis care unless specifically prescribed by a healthcare provider for a particular reason.
