Correct Answer: A

Rationale: The correct answer is A: Fidelity. Fidelity in nursing ethics involves keeping promises and being faithful to commitments, demonstrating reliability and trustworthiness. In this scenario, the nurse is exemplifying fidelity by returning promptly to the client as promised. Choice B, Autonomy, refers to respecting a patient's right to make their own decisions, not relevant in this situation. Choice C, Beneficence, involves the duty to act in the best interest of the patient, which is not the primary focus here. Choice D, Justice, pertains to fairness and equity in the distribution of healthcare resources, not applicable to the nurse's actions in this case.

Correct Answer: D

Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.

Correct Answer: C

Rationale: To administer 250 mL over 30 min with a drop factor of 10 gtt/mL, the healthcare professional should adjust the IV infusion to deliver 100 gtt/min. The correct calculation is: (250 mL · 30 min) x 10 gtt/mL = 100 gtt/min. This rate ensures the proper administration of the IV solution within the specified time frame. Choices A, B, and D are incorrect as they do not align with the accurate calculation based on the provided data.

Correct Answer: D

Rationale: The correct answer is to initiate contact precautions when providing client care. C-diff (Clostridium difficile) is highly contagious, and contact precautions are necessary to prevent its spread. Giving the client chlorhexidine gluconate for hand hygiene (Choice A) is not specific to managing C-diff. Removing the protective gown first when exiting the client's room (Choice B) may increase the risk of contaminating oneself and the environment. Using alcohol-based hand rub when caring for the client (Choice C) is not sufficient to prevent the transmission of C-diff, as soap and water are more effective against this particular pathogen.

Correct Answer: C

Rationale: Taking medications immediately after breastfeeding helps minimize the amount of medication that enters breast milk. By doing so, there is a longer interval between the medication intake and the next breastfeeding session, reducing the concentration of the medication in breast milk. Options A and B are incorrect as drinking water with medication or using medications with a short half-life do not directly minimize the entry of medication into breast milk. Option D is unnecessary and wasteful as pumping and discarding breast milk before feeding is not as effective as timing medication intake with breastfeeding to reduce medication transfer into breast milk.
