What happens to the BP and pulse rate after exercise?
The pulse and BP increase after exercise. When we exercise, our muscles require more oxygen for working. The heart starts to work faster to supply oxygen to the muscles, hence the BP and heart rate (pulse) increase.
A 47-year-old man comes into the hospital complaining of progressive shortness of breath for 2 weeks, ankle edema, and low oxygen saturation. The nurse applies oxygen at 2L and the patient's saturation comes up from 86% to 93%. What laboratory marker is important in ruling out congestive heart failure in this patient?
A. CBC B. TSH C. BNP D. CMP The correct answer is C. BNP stands for B-type natriuretic peptide which is a hormone produced by the heart. It is released when there is an excess amount of fluid around a patient's heart to prevent the heart from working hard. For ex: a BNP level of >1000 is suggestive of CHF, meaning there is too much fluid around a patient's heart confirming why the patient is short of breath and has poor oxygen levels. Also, suggests the concern for ankle edema.

How does one manage reading 20 chapters in a textbook and to study for the said 20 chapters?
Personally, I've never been one to read the textbook because it is time-consuming and you don't retain all the necessary information. I find reviewing the lecture notes from class and referring back to the textbook on any topic I don't understand. Additionally, I try to answer the questions listed at the end of each chapter as those provide a good summary of the chapter and at the same time, it challenges you really think. Lastly, if I still don't understand a specific topic, I will read the specific page and find helpful videos online that help me understand the topic better. Sometimes, we need outside resources to facilitate our understanding of the topic.
