A 24-year-old female with a history of severe anorexia nervosa is admitted to the medical floor following a fainting episode. Physical examination reveals a body mass index (BMI) of 14.2 kg/m², bradycardia, and dry mucous membranes. Initial laboratory results reveal: Arterial Blood Gas (ABG): pH 7.31, PaCO₂ 32 mmHg, HCO₃⁻ 16 mEq/L Serum Electrolytes: Na⁺ 138 mEq/L, Cl⁻ 102 mEq/L, K⁺ 3.4 mEq/L Anion Gap: 20 mEq/L (Elevated) Serum Glucose: 58 mg/dL Serum Ketones: Strongly positive Which of the following physiological mechanisms best explains the primary driver of this patient’s acid-base imbalance?

You are caring for a patient with chronic constipation and asks you as the provider what they can do at home to improve there symptoms. What is the most appropriate response?

You are caring for a 78 year-old male that presents to you with diarrhea and you suspect malabsorption. His stool pathogen testing (O&P, EIA, Giardia/Cryptosporidium Ag) has been negative. What intervention should be consider next?

Explain what causes friction?    (There are a few causes, describe at least one)  

A box of weight 10N rests still on a flat table.    = 0.7, and = 0.3 +x direction is to the right  you push on the box to the right with 5N of force Your friend wants to determine the frictional force acting on the box and its direction as well as whether the box will remain still and in equilibrium.   Your friend concludes the box will move to the left using the 7 logical steps below   Explain what statements, if any are incorrect and why. Explain in detail. If it helps to explain the correct ones too then go for it. If there are errors with your friends logical steps, write out all the logical steps you would take to reach the correct conclusion about this problem. (include the correct numbers as well as the correct conclusion)   1)       N = 10N for this problem 2)       calculates to be 7N 3)       thus, there is 7N of friction force. 4)       If there was no friction, then from the sum of forces in the x direction the box will move to the right 5)       Thus, the frictional force is to the left on the box, to oppose the direction the box wants to move 6)       So, the sum of forces in the x direction with friction is -7N + 5N = -2N 7)       Therefore, the box will accelerate to the left and not remain still    

If there was a box on a slanted table and no other forces, how would you find N? No need for numbers here, just conceptually how would you do it?

Explain the relationship between the 5 stages of the cardiac cycle and how they would appear on an ECG graph. What are the parts of the ECG graph called?

In your own words, discuss the elements of direct quotes that you feel most confident about. Then discuss what concepts (related to direct quotes) that you are still confused about. If you understand everything, then still discuss some of the concepts we covered this week to illustrate that you read carefully.

Patients about to undergo an angiography exam should be well hydrated.
