Cardiovascular System Exam Questions And Answers
1. What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?
- A. Pneumonia
- B. Tuberculosis
- C. Asthma
- D. Bronchitis
Correct answer: A
Rationale: Pneumonia is the correct answer. It is an infection that inflames the air sacs in one or both lungs, leading to the accumulation of fluid or pus, which results in symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (choice B) is a bacterial infection affecting the lungs but does not typically cause the same acute symptoms as described. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, not specifically involving the air sacs. Bronchitis (choice D) is an inflammation of the bronchial tubes, not the air sacs in the lungs, and does not typically cause the same symptoms as pneumonia.
2. How are values learned?
- A. Reading books
- B. Formal degrees
- C. Continuous reinforcement
- D. Meeting diverse individuals
Correct answer: C
Rationale: Values are learned through continuous reinforcement, where behaviors or beliefs are strengthened by consequences or rewards. Reading books (choice A) may expose individuals to different perspectives and values, but the active learning and internalization of values typically occur through reinforcement. Formal degrees (choice B) may provide education and knowledge, but values are more likely to be ingrained through continuous reinforcement. Meeting diverse individuals (choice D) can also influence values, but the consistent reinforcement of desired behaviors is a more direct method for learning values.
3. What should the healthcare provider consider when providing support to a family whose infant has just been diagnosed with biliary atresia?
- A. The prognosis for full recovery is excellent.
- B. Death usually occurs by 6 months of age.
- C. Liver transplantation may be needed eventually.
- D. Children with surgical correction live normal lives.
Correct answer: C
Rationale: When supporting a family whose infant has been diagnosed with biliary atresia, it is important to consider that liver transplantation may be needed eventually. Biliary atresia is a serious condition where bile flow from the liver to the gallbladder is blocked or absent. While surgical interventions like the Kasai procedure can temporarily improve bile flow and delay the need for transplantation, the long-term survival often depends on liver transplantation as the child grows older. Choices A, B, and D are incorrect because the prognosis for full recovery is not excellent as biliary atresia is a chronic condition that often requires ongoing medical management, death usually does not occur by 6 months of age but the condition does require intervention, and not all children with surgical correction can live normal lives without the need for further interventions like transplantation.
4. The client is receiving digoxin and has a potassium level of 2.8 mEq/L. What is the nurse’s priority action?
- A. Hold the digoxin and notify the healthcare provider.
- B. Increase the dose of digoxin.
- C. Continue the current dose of digoxin.
- D. Administer potassium supplements.
Correct answer: A
Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 2.8 mEq/L indicates hypokalemia, which can increase the risk of digoxin toxicity. Holding the medication and informing the healthcare provider is crucial to prevent adverse effects. Choice B is incorrect because increasing the dose of digoxin would further raise the risk of toxicity. Choice C is incorrect as continuing the current dose could exacerbate the toxicity risk. Choice D is incorrect because administering potassium supplements alone is not sufficient to address the potential digoxin toxicity; the first step should be to hold the digoxin and seek further guidance.
5. If there is an accidental injury to the parathyroid gland during a thyroidectomy which of the following might Leda develop postoperatively?
- A. Cardiac arrest C. Respiratory failure
- B. Dyspnea D. Tetany
- C.
- D.
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
