Cardiovascular System Exam Questions And Answers
1. The client is given an alpha agonist. What might it be used for?
- A. For hemostasis
- B. To dilate the arteries
- C. To dilate the veins
- D. To decrease afterload
Correct answer: A
Rationale: Alpha agonists are used for hemostasis to help control bleeding by constricting blood vessels, leading to decreased blood flow to the area. Choices B, C, and D are incorrect as alpha agonists do not typically dilate arteries, dilate veins, or decrease afterload.
2. What is the term for a barrier that prevents the normal emptying of stomach contents into the duodenum?
- A. Dumping syndrome
- B. Gastritis
- C. Gastric outlet obstruction
- D. Hypochlorhydria
Correct answer: C: Gastric outlet obstruction
Rationale: Gastric outlet obstruction refers to a condition where the opening between the stomach and the duodenum is blocked, preventing the normal passage of food. This is why choice 'C' is correct. 'A: Dumping syndrome' is incorrect because it is a condition where stomach contents move too quickly through the small intestine, not a barrier preventing emptying. 'B: Gastritis' is inflammation of the stomach lining, not a blockage of the outlet. 'D: Hypochlorhydria' refers to low stomach acid, which may affect digestion but does not create a physical barrier blocking the outlet of the stomach.
3. The nurse is reviewing the Healthy People 2020 leading health indicators for a child health promotion program. Which are included in the leading health indicators? (Select all that apply.)
- A. Decrease tobacco use
- B. Improve immunization rates
- C. All are applicable
- D. Increase access to health care
Correct answer: C
Rationale: Healthy People 2020 focuses on decreasing tobacco use, improving immunization rates, and increasing access to healthcare among its leading health indicators.
4. A nurse is providing teaching to a client who has a new prescription for albuterol. Which of the following client statements indicates an understanding of the teaching?
- A. I will use this medication to prevent an asthma attack.
- B. I will use this medication for shortness of breath during an asthma attack.
- C. I will take this medication with my daily vitamins.
- D. I will take this medication at bedtime to prevent an asthma attack.
Correct answer: B
Rationale: The correct answer is B because albuterol is used to treat shortness of breath during an asthma attack. Choice A is incorrect as albuterol is a rescue medication used during an asthma attack, not for prevention. Choice C is incorrect as albuterol should not be taken with daily vitamins. Choice D is incorrect as albuterol is not typically taken at bedtime for asthma prevention.
5. A client has hypertension and a potassium level of 6.8 mEq/L. Which of the following actions should the nurse take?
- A. Suggest that the client use a salt substitute
- B. Obtain a 12-lead ECG
- C. Obtain a blood sample for a serum sodium level
- D. Advise the client to add citrus juices and bananas to their diet
Correct answer: B
Rationale: Obtaining a 12-lead ECG is crucial in this situation to assess cardiac function due to the elevated potassium level. High potassium levels can lead to dangerous arrhythmias, and an ECG helps in detecting any cardiac abnormalities. Choices A, C, and D are incorrect. Suggesting a salt substitute can further elevate the client's potassium levels. Checking serum sodium levels is not the priority when dealing with high potassium levels. Advising the client to add citrus juices and bananas, which are high in potassium, would worsen the situation.
