1. Question 1 (MCQ): A patient presents with dehydration. Which hormone is responsible for increasing water reabsorption in the kidneys?
A. Aldosterone
B. ADH
C. Insulin
D. Cortisol
2, Question 2 (Case Study): A patient with chronic kidney disease has a creatinine level of 2.5 mg/dL. What does this indicate?
A. Normal kidney function
B. Impaired kidney function
C. Dehydration
D. Overhydration
3. Question 3 (True/False):High levels of ADH in a hydrated patient can lead to water intoxication.
4. Question 4 (Prioritization):A patient with kidney failure requires immediate intervention. Which of the following lab values should be addressed first?
A. Serum potassium of 6.5 mEq/L
B. Blood urea nitrogen (BUN) of 70 mg/dL
C. Creatinine of 4.0 mg/dL
D. pH of 7.30
5.Question 5 (Calculation):A patient’s blood pressure is 90/60 mmHg. Which of the following ADH responses is expected?
A. Increased ADH
B. Decreased ADH
C. No change in ADH
Answers and Rationa:
1. Answer: B. Rationale: ADH (antidiuretic hormone) plays a critical role in dehydration by signaling the kidneys to reabsorb water and concentrate urine.
2. Answer: B. Rationale: Elevated creatinine levels (above 1.3 mg/dL for women and 1.2 mg/dL for men) indicate impaired kidney function, often due to kidney disease or failure.
3, Answer: True ❌Rationale: Excess ADH in a well-hydrated individual can cause water retention, leading to hyponatremia (low sodium levels) or water intoxication.
4: Answer: A. Rationale: Hyperkalemia (elevated potassium levels) is a life-threatening emergency that requires immediate intervention, as it can lead to cardiac arrest.
5. Answer: A. Rationale: Low blood pressure triggers the release of ADH to increase water reabsorption and blood volume.
