Cardiovascular System Exam Questions
1. The client is on dobutamine. Adverse effects of Dobutrex (dobutamine) include the following: Select all that apply.
- A. Heart failure
- B. Bradycardia
- C. Tachycardia
- D. Respiratory distress
Correct answer: C
Rationale: The correct answer is C: Tachycardia. Dobutamine is a medication that primarily increases heart rate (tachycardia) and blood pressure. Therefore, the adverse effects of dobutamine include tachycardia. Choices A, B, and D are incorrect. Heart failure is not an adverse effect of dobutamine; in fact, it is used to treat heart failure by increasing heart contractility. Bradycardia (slow heart rate) is not an expected adverse effect of dobutamine, as it usually increases heart rate. Respiratory distress is not a common adverse effect of dobutamine.
2. The nurse is administering an ACE inhibitor to a client. What is the most common side effect?
- A. Cough
- B. Dizziness
- C. Hypotension
- D. Hyperkalemia
Correct answer: A
Rationale: The correct answer is A: Cough. Cough is a well-known side effect of ACE inhibitors due to an increase in bradykinin levels. This irritating cough can be bothersome to clients and should be monitored. Choice B, Dizziness, is not the most common side effect of ACE inhibitors. While ACE inhibitors can cause hypotension (Choice C), cough is more prevalent. Hyperkalemia (Choice D) is a possible side effect of ACE inhibitors but is less common compared to cough.
3. When monitoring a client on dobutamine, what is the most important parameter to assess?
- A. Blood pressure
- B. Heart rate
- C. Oxygen saturation
- D. Respiratory rate
Correct answer: A
Rationale: The correct answer is A: Blood pressure. When a client is on dobutamine, it is crucial to closely monitor their blood pressure as dobutamine can cause significant changes in blood pressure. While heart rate is also important to monitor during this time, blood pressure is the most critical parameter to assess. Oxygen saturation and respiratory rate are also important parameters to monitor in a patient receiving dobutamine, but they are not as crucial as blood pressure in this scenario.
4. The nurse is giving nitroglycerin sublingually for chest pain. What is the most important instruction to give to the client?
- A. Place the tablet under the tongue and let it dissolve completely.
- B. Swallow the tablet whole with a glass of water.
- C. Chew the tablet and then swallow it.
- D. Take one tablet every 5 minutes until pain is relieved.
Correct answer: A
Rationale: The correct answer is A. The tablet should be placed under the tongue and allowed to dissolve completely to ensure rapid absorption. This route of administration allows the medication to be quickly absorbed into the bloodstream. Choice B is incorrect because nitroglycerin is meant to be absorbed sublingually, not swallowed. Choice C is incorrect as chewing the tablet can cause the medication to be rapidly absorbed, leading to adverse effects like a drop in blood pressure. Choice D is incorrect because the client should take only one tablet every 5 minutes up to a maximum of three tablets for chest pain relief.
5. What is an acute respiratory infection that inflames the alveoli in one or both lungs, causing them to fill with fluid or pus?
- A. Pneumonia
- B. Bronchitis
- C. Tuberculosis
- D. Asthma
Correct answer: A
Rationale: Pneumonia is the correct answer because it is an acute respiratory infection that inflames the alveoli in one or both lungs, leading to the accumulation of fluid or pus. This condition presents with symptoms like cough, fever, and difficulty breathing. Bronchitis is the inflammation of the bronchial tubes, not the alveoli. Tuberculosis is a bacterial infection that primarily affects the lungs but does not always result in alveolar inflammation. Asthma is a chronic respiratory condition characterized by airway inflammation and narrowing, not alveolar inflammation.
