Correct Answer: A

Rationale: Nagele's rule is a method used to calculate the expected delivery date by subtracting 3 months from the first day of the last menstrual period and adding 7 days. In this case, April 12 minus 3 months is January 12, plus 7 days gives January 19. Therefore, the correct answer is A. Choices B, C, and D do not align with the application of Nagele's rule and are incorrect.

Correct Answer: D

Rationale: Contacting the pharmacist is the most appropriate action to ensure the correct medication is being administered. This response addresses the client's concern directly and prioritizes patient safety. The other options do not directly address the issue of the medication discrepancy. Option A focuses on the healthcare provider's discussion, not the medication itself. Option B assumes that the current medication is correct without verification. Option C addresses the reason for the prescription but does not verify the medication's correctness.

Correct Answer: B

Rationale: Lorazepam is the correct medication to administer in this situation. It is used to manage the symptoms of alcohol withdrawal and prevent complications like seizures and delirium tremens. Metoclopramide is primarily used to treat gastrointestinal issues, Haloperidol is an antipsychotic medication used for conditions like schizophrenia, and Methadone is typically used in managing opioid dependence. These medications are not the first-line treatment for alcohol withdrawal.

Correct Answer: A

Rationale: Corrected Rationale: Weak femoral pulses are an expected finding in an infant with coarctation of the aorta. The narrowing of the aorta leads to decreased blood flow to the lower extremities, resulting in weak or absent femoral pulses. Frequent nosebleeds (Choice B) are not typically associated with coarctation of the aorta. Upper extremity hypotension (Choice C) is not a common finding in coarctation of the aorta; instead, blood pressure is usually elevated in the upper extremities. Increased intracranial pressure (Choice D) is not directly related to coarctation of the aorta.

Correct Answer: A

Rationale: In a client with a sodium level of 125 mEq/L (hyponatremia), the nurse should administer 0.9% sodium chloride IV to help increase sodium levels. Choice B, administering a hypotonic IV solution, would further decrease the sodium level. Choice C, encouraging oral fluid intake, is contraindicated as it can dilute the sodium concentration further. Choice D, restricting oral fluid intake, could worsen the client's condition by leading to dehydration and further electrolyte imbalances.
