ATI Pathophysiology Exam 1
1. Which condition is characterized by a lack of antidiuretic hormone (ADH)?
- A. Diabetes mellitus
- B. Diabetes insipidus
- C. Cushing's disease
- D. Hyperthyroidism
Correct answer: B
Rationale: The correct answer is B, Diabetes insipidus. Diabetes insipidus is characterized by a lack of antidiuretic hormone (ADH), leading to excessive urination and thirst. Choice A, Diabetes mellitus, is a different condition characterized by high blood sugar levels. Choice C, Cushing's disease, is caused by prolonged exposure to high levels of cortisol. Choice D, Hyperthyroidism, involves an overactive thyroid gland producing excess thyroid hormones.
2. A nurse is assessing a client who is receiving furosemide for heart failure. Which of the following findings is the priority to report to the provider?
- A. Blood pressure of 98/58 mm Hg
- B. Urine output of 50 mL/hr
- C. Serum potassium level of 3.2 mEq/L
- D. Weight loss of 0.5 kg (1.1 lb) in 24 hours
Correct answer: C
Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L indicates hypokalemia, a potential complication of furosemide therapy, and should be reported immediately. Hypokalemia can lead to serious cardiac dysrhythmias. Choices A, B, and D are important assessments but are not as critical as managing serum potassium levels in a client receiving furosemide for heart failure.
3. The nurse is teaching a client about side effects of ACE inhibitors. What is the most important side effect to monitor?
- A. Cough
- B. Hyperkalemia
- C. Hypotension
- D. Dizziness
Correct answer: A
Rationale: The correct answer is A: Cough. ACE inhibitors commonly cause a persistent dry cough in patients. This side effect is important to monitor because it can indicate the development of angioedema, a serious adverse reaction that requires immediate medical attention. Hyperkalemia (choice B) is a potential side effect of ACE inhibitors but is not typically the most important one to monitor. Hypotension (choice C) and dizziness (choice D) are also possible side effects of ACE inhibitors, but they are not as critical to monitor as the development of a persistent cough.
4. A client has suffered from a femur fracture. What is the nurse’s priority assessment?
- A. Pain
- B. Medication history
- C. Pedal pulses
- D. Socio-economic status
Correct answer: Pedal pulses

- C. Of course I will heat that up for you.
