Correct Answer: A

Rationale: The correct answer is A: Communication. Healthcare records are essential for effective communication among healthcare providers to ensure continuity of care. They help convey important information about a patient's condition, treatment plan, and progress. Explanation: 1. Communication: Healthcare records facilitate communication between different healthcare team members, ensuring coordinated and efficient care delivery. 2. Legal documentation: While important, legal documentation is a separate purpose of healthcare records, not directly related to communication. 3. Reimbursement: Healthcare records are used for billing and reimbursement purposes, but this is not directly related to communication. 4. Nursing process: The nursing process involves assessment, diagnosis, planning, implementation, and evaluation of patient care, which is documented in healthcare records. However, this is not a primary purpose related to communication.

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: A

Rationale: The correct answer is A: Provide emotional support to the patient and her family. This is the priority as the patient has received devastating news and needs immediate support. Emotional support can help the patient cope with the diagnosis, express feelings, and make decisions. B: Implementing distraction techniques may not address the patient's emotional needs in this critical situation. C: Offering to inform the family of the diagnosis is important but not the priority at this moment. D: Teaching about maintaining a positive attitude may not be appropriate as the patient is facing a terminal illness.

Correct Answer: C

Rationale: The correct answer is C because encouraging the patient to verbalize concerns can help alleviate anxiety by allowing the patient to express emotions and fears. This intervention promotes emotional expression and provides an outlet for the patient to discuss their worries. This can lead to increased understanding and support. Incorrect answers: A: Administering antianxiety medications does not address the underlying cause of anxiety and may lead to dependency. B: Instructing the family on planning care does not directly address the patient's anxiety. D: Distracting the patient may provide temporary relief but does not address the root cause of anxiety related to lack of control over health circumstances.

Correct Answer: A

Rationale: The correct answer is A because a protein level of 2 mg/100 mL in urine indicates proteinuria, which can be a sign of kidney dysfunction or other underlying health issues. The nurse should follow up to assess further for possible kidney disease or other conditions. Choice B is not a cause for concern as a urine output of 80 mL/hr is within the normal range. Choice C indicates concentrated urine, which may be due to dehydration but does not necessarily require immediate follow-up. Choice D is within the normal range for urine pH and does not typically warrant immediate follow-up.
