Correct Answer: A

Rationale: The correct way to prevent self-injury when lifting a bedside cabinet is by standing close to the cabinet. By standing close, the individual can maintain better control and balance while lifting, reducing the risk of injury. Bending at the waist when lifting (choice B) can strain the back and lead to injury. Twisting while lifting (choice C) can also cause strain and imbalance. Lifting with a quick motion (choice D) can increase the risk of injury due to lack of control and improper body mechanics.

Correct Answer: D

Rationale: The correct answer is D: Beneficence. Beneficence involves actions intended to benefit the client, such as providing pain relief. In this scenario, the nurse is demonstrating beneficence by offering pain medication to alleviate the client's discomfort and promote their well-being. Fidelity (A) relates to being faithful to agreements and commitments, autonomy (B) refers to respecting a client's right to make decisions about their care, and justice (C) involves fairness and equal treatment. While these ethical principles are important in healthcare, the situation described primarily exemplifies the principle of beneficence.

Correct Answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

Correct Answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

Correct Answer: B

Rationale: The correct answer is B. Assigning the UAP to report hourly outputs of less than 30 ml/hr is appropriate as it falls within their scope of practice and does not involve making clinical assessments or decisions. Choices A, C, and D involve tasks that require a higher level of clinical judgment and training. Choice A requires assessing mucous membranes, which is beyond the UAP's scope. Choice C involves assessing movement ability, which requires more specialized training. Choice D involves assessing skin turgor, which also requires a higher level of clinical judgment.
