ATI Pathophysiology Exam 1
1. What is a common factor related to all forms of heart failure?
- A. Peripheral edema
- B. Pulmonary edema
- C. Reduced cardiac output
- D. Jugular vein distention
Correct answer: C
Rationale: The correct answer is C: Reduced cardiac output. All forms of heart failure share this common factor, which occurs when the heart is unable to pump enough blood to meet the body's needs. Choices A, B, and D are incorrect. While peripheral edema and pulmonary edema can be symptoms of heart failure, they are not universal to all forms. Jugular vein distention is a sign of right heart failure, not a common factor across all types of heart failure.
2. The healthcare provider is administering IV nitroglycerin to a patient for chest pain. What is the most critical parameter to monitor?
- A. Heart rate
- B. Blood pressure
- C. Oxygen saturation
- D. Respiratory rate
Correct answer: B
Rationale: The correct answer is 'Blood pressure.' Nitroglycerin is a vasodilator that can cause a rapid drop in blood pressure, leading to hypotension. Monitoring the blood pressure is crucial to prevent potential complications such as hypotension-induced dizziness, syncope, or organ hypoperfusion. While heart rate, oxygen saturation, and respiratory rate are important parameters to monitor in a clinical setting, the immediate concern with IV nitroglycerin administration is the risk of hypotension, making blood pressure the most critical parameter to assess.
3. An occurrence of too high a concentration of which of the following electrolytes is associated with cardiac arrhythmias?
- A. chloride
- B. phosphorus
- C. potassium
- D. sodium
Correct answer: potassium
Rationale: The correct answer is potassium. High levels of potassium in the blood, known as hyperkalemia, can lead to cardiac arrhythmias by affecting the electrical activity of the heart. This can disrupt the normal rhythm of the heart and lead to serious complications. Chloride, phosphorus, and sodium imbalances are not typically associated with cardiac arrhythmias, making them incorrect choices.
4. Which condition is caused by a bacterium that primarily affects the lungs but can spread to other parts of the body?
- A. Tuberculosis
- B. Pneumonia
- C. Legionnaires' disease
- D. Histoplasmosis
Correct answer: A
Rationale: The correct answer is A, Tuberculosis. Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, primarily affecting the lungs but can spread to other organs. Choice B, Pneumonia, is an infection that inflames the air sacs in one or both lungs. Choice C, Legionnaires' disease, is a severe form of pneumonia caused by the Legionella bacteria. Choice D, Histoplasmosis, is a fungal infection caused by inhaling spores of the Histoplasma capsulatum fungus.
5. A client has been taking aluminum hydroxide 30 mL six times per day at home to treat his peptic ulcer. He tells the nurse that he has been unable to have a bowel movement for 3 days. Based on this information, the nurse would determine that which of the following is the most likely cause of the client’s constipation?
- A. The client has not been including enough fiber in his diet
- B. The client needs to increase his daily exercise
- C. The client is experiencing a side effect of the aluminum hydroxide.
- D. The client has developed a gastrointestinal obstruction.
Correct answer: C
Rationale: The client is experiencing a common side effect of aluminum hydroxide, which is constipation.
