Correct Answer: B

Rationale: Antibiotic ointment is ineffective against athlete's foot, which is a fungal infection. The nurse should instruct the mother to stop using the ointment and ensure the feet are dried properly, as moisture exacerbates fungal infections. Applying a different antifungal medication is a valid option, but addressing the moisture issue by drying the feet completely is the immediate priority. Continuing to use the antibiotic ointment or reapplying it for a longer period will not treat the fungal infection effectively.

Correct Answer: A

Rationale: Being aware of cultural differences is crucial because normal behaviors in one culture may be perceived as deviant, immoral, or insane in another. This awareness helps the nurse avoid misunderstandings or misinterpretations of behaviors that are considered acceptable in the client's cultural context but may be viewed differently in another. Choices B, C, and D are incorrect because understanding cultural issues goes beyond deriving meanings from conventional wisdom, personal values guiding interactions, or relying solely on knowledge of developmental mental stages.

Correct Answer: B

Rationale: The correct answer is B: 'Take the medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to enhance absorption and effectiveness. The medication is typically taken in the morning before breakfast. Choice A is incorrect because taking levothyroxine with a full meal can decrease its absorption. Choice C is incorrect because bedtime dosing may lead to insomnia. Choice D is incorrect because levothyroxine is a daily medication for hypothyroidism, not to be taken as needed for symptoms.

Correct Answer: D

Rationale: Verifying the blood type with another nurse is critical before starting a blood transfusion to prevent a potentially life-threatening transfusion reaction. This step ensures that the client receives the correct blood product. Administering pre-transfusion medication, ensuring adequate fluid intake, and monitoring vital signs are important steps during the transfusion process, but verifying the blood type is the most crucial step to ensure patient safety.

Correct Answer: B

Rationale: A decrease in white blood cell count indicates that the infection is responding to treatment and the client's condition is improving. Monitoring the white blood cell count is a more objective indicator of the body's response to the antibiotics. Choices A, C, and D may also be positive signs, but they are less specific and may vary among individuals. Respiratory rate alone may not be sufficient to indicate improvement, as other factors can influence it. Energy levels and cough characteristics are subjective and may not always correlate with the effectiveness of antibiotic treatment.
