Correct Answer: D

Rationale: The correct answer is D, Nonmaleficence. Nonmaleficence refers to the principle of 'do no harm.' In this scenario, questioning a potentially harmful prescription for a client with advanced age and unstable status aligns with the principle of nonmaleficence, as the nurse is advocating for the client's safety and well-being. Choice A, Fidelity, refers to being faithful and keeping promises, which is not directly related to the situation described. Choice B, Autonomy, pertains to respecting a patient's right to make their own decisions, which is not the focus of the nurse questioning the prescription. Choice C, Justice, involves fairness and equal treatment, which is not the primary ethical principle at play in this situation.

Correct Answer: C

Rationale: During a Romberg's test, the nurse assesses the client's balance. Having the client stand with arms at her sides and feet together is the correct technique. This position helps the nurse observe for swaying or loss of balance, indicating alterations in balance. Choices A and B are incorrect as they are not part of Romberg's test and do not assess balance. Choice D is also incorrect as direct percussion over the kidneys is not associated with a Romberg's test.

Correct Answer: C

Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.

Correct Answer: B

Rationale: To calculate the number of tablets needed, convert the prescribed dose of Seconal from grams to grains. Since 1 gram is equal to approximately 15.43 grains, 0.1 gram is roughly 1.543 grains. Given that each tablet contains 1.5 grains, administering 1 tablet (which is slightly more than the 1.543 grains needed) provides the correct dose of Seconal. Therefore, the LPN/LVN should plan to administer 1 tablet. Choice A (0.5 tablet) is incorrect as it would provide less than the required dose. Choice C (1.5 tablets) and Choice D (2 tablets) are incorrect as they would exceed the necessary dosage.
