Correct Answer: C

Rationale: Rationale for correct answer C: In Hashimoto's thyroiditis, an autoimmune disorder causing hypothyroidism, we expect to see normal to elevated TSH levels due to the pituitary gland stimulating the thyroid to produce more hormones. T4 and T3 levels may be within normal range or slightly decreased. Choice C reflects this pattern with T4 at 22 ug/dl, T3 at 200 ng/dl, and TSH at 0.1 uIU/ml. Summary of why other choices are incorrect: - Choice A: T4 and T3 levels are higher than expected in Hashimoto's thyroiditis, and TSH should be elevated, not stated as normal. - Choice B: An undetectable TSH level is typically seen in hyperthyroidism, not hypothyroidism like Hashimoto's. - Choice D: T4 and T3 levels are significantly lower than expected, and TSH is much higher than typically seen in Hashimoto's

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Applying antibiotic ointment and placing the mother in reverse isolation are not appropriate for managing vesicles suspected to be herpes simplex virus (HSV) during labor. 2. HSV can be transmitted to the baby during vaginal delivery, leading to serious consequences. 3. Standard precautions should always be maintained to prevent the spread of infections. 4. Preparing for the possibility of a cesarean section and notifying the obstetrician about the vesicles are important steps to protect the baby and staff from potential harm.

Correct Answer: D

Rationale: The correct answer is D: Stapedectomy. This procedure is used to correct otosclerosis by removing the stapes bone and replacing it with a prosthetic device. This restores normal hearing by allowing sound waves to travel through the ear properly. Myringotomy (A) is a procedure to drain fluid from the middle ear, not to correct otosclerosis. Mastoidectomy (B) is the removal of infected mastoid air cells, not related to otosclerosis. Myringoplasty (C) is a surgical procedure to repair a perforated eardrum, not used for otosclerosis. Stapedectomy is the most appropriate choice for correcting otosclerosis as it directly addresses the abnormal bone growth in the middle ear.

Correct Answer: B

Rationale: The correct answer is B, "What reasons do you think are contributing to your fatigue?" This question encourages the patient to explore and express their own thoughts and feelings, leading to a more detailed and comprehensive understanding of the underlying causes of their daytime fatigue. A: "Is there anything that you are stressed about right now that I should know?" - This question is more direct and may not necessarily prompt the patient to delve into the specific reasons for their fatigue. C: "What are your normal work hours?" - While relevant, this question focuses solely on work hours and may not uncover other potential factors contributing to the fatigue. D: "Are you sleeping 8 hours a night?" - While sleep is important, this question is too narrow and may not address other possible reasons for the fatigue.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Aseptic technique prevents infection at IV site. 2. TPN is a high-risk solution, requiring strict aseptic administration. 3. Contaminated site can lead to sepsis or other serious complications. 4. Choice B increases risk of contamination. 5. Choice C increases risk of bacterial growth. 6. Choice D may introduce air or contamination. Summary: Choice A is correct as it emphasizes infection prevention. Choices B, C, and D pose risks of contamination, bacterial growth, or air introduction.
