Cardiovascular System Exam Questions Pdf
1. Which of the following is a chronic condition where the heart muscle is weakened and unable to pump blood effectively, often leading to heart failure?
- A. Dilated cardiomyopathy
- B. Hypertrophic cardiomyopathy
- C. Restrictive cardiomyopathy
- D. Myocarditis
Correct answer: A
Rationale: Dilated cardiomyopathy is characterized by the heart muscle being weakened and unable to pump blood effectively, ultimately resulting in heart failure. Choice B, Hypertrophic cardiomyopathy, involves the heart muscle becoming abnormally thick, reducing the heart's efficiency. Choice C, Restrictive cardiomyopathy, refers to the heart becoming rigid and less able to fill with blood properly. Myocarditis, as in Choice D, is inflammation of the heart muscle usually caused by a viral infection and is different from the chronic weakening seen in dilated cardiomyopathy.
2. The healthcare provider is monitoring a client on an ACE inhibitor. What lab value is most important to monitor?
- A. Potassium
- B. Sodium
- C. Creatinine
- D. Calcium
Correct answer: A
Rationale: The correct answer is A: Potassium. When a client is on an ACE inhibitor, it is crucial to monitor potassium levels because ACE inhibitors can lead to an increase in potassium, potentially causing hyperkalemia. Monitoring sodium levels (Choice B) is not as critical in this scenario. Creatinine levels (Choice C) are important for assessing kidney function but are not the most crucial lab value to monitor with ACE inhibitors. Calcium levels (Choice D) are not directly affected by ACE inhibitors and are not the priority for monitoring in this case.
3. A child is being assessed for acute poststreptococcal glomerulonephritis (APSGN). Which of the following findings should the nurse expect?
- A. Hematuria
- B. Polyuria
- C. Hypertension
- D. Diarrhea
Correct answer: C
Rationale: In acute poststreptococcal glomerulonephritis (APSGN), hypertension is a common finding due to fluid retention and decreased kidney function. This condition often presents with hypertension as a result of sodium and water retention, as well as reduced glomerular filtration rate. Hematuria, not diarrhea, is also a common symptom of APSGN due to inflammation and damage to the glomeruli. Polyuria, an increase in urine output, is not a typical finding in APSGN unless severe kidney damage leads to decreased urine concentrating ability.
4. A nurse is assessing a client who has a heart rate of 40/min. The client is diaphoretic and has chest pain. Which of the following medications should the nurse plan to administer?
- A. Lidocaine
- B. Adenosine
- C. Atropine
- D. Verapamil
Correct answer: C
Rationale: The correct answer is C: Atropine. The client's presentation of bradycardia, diaphoresis, and chest pain indicates reduced cardiac output, requiring intervention to increase the heart rate. Atropine is used to treat bradycardia by blocking cardiac muscarinic receptors, thus inhibiting the parasympathetic nervous system. Lidocaine (Choice A) is used for ventricular arrhythmias, not bradycardia. Adenosine (Choice B) is used for supraventricular tachycardia, not bradycardia. Verapamil (Choice D) is a calcium channel blocker used for certain arrhythmias and hypertension, but not for increasing heart rate in bradycardia.
5. Deferred imitation of a caregiver's behavior shows that toddlers have the capacity to form?
- A. Short-term memory
- B. Working memory
- C. Core memories
- D. Long-term memory
Correct answer: D
Rationale: Deferred imitation refers to the ability of toddlers to observe and replicate behaviors after a period of time, indicating the formation of long-term memories. This process involves storing information for an extended period and recalling it at a later time. This capacity is not attributed to short-term memory (choice A), which is more temporary in nature and has limited storage capacity. Working memory (choice B) involves the temporary storage and manipulation of information for cognitive tasks, not necessarily the long-term retention of behaviors. Core memories (choice C) are typically associated with emotional or significant events rather than the replication of observed behaviors. Therefore, the correct answer is choice D, as deferred imitation demonstrates toddlers' capability to form long-term memories by replicating behaviors observed earlier.
