Cardiovascular System Exam
1. Which type of heart valve disease occurs when the mitral valve does not close properly, allowing blood to flow backward into the left atrium?
- A. Mitral regurgitation
- B. Aortic stenosis
- C. Tricuspid regurgitation
- D. Pulmonary hypertension
Correct answer: A
Rationale: Mitral regurgitation is the correct answer. It occurs when the mitral valve does not close properly, allowing blood to flow backward into the left atrium. This condition can lead to symptoms such as fatigue, shortness of breath, and if left untreated, it can progress to heart failure. Aortic stenosis (choice B) is a different heart valve condition characterized by narrowing of the aortic valve, restricting blood flow from the heart. Tricuspid regurgitation (choice C) involves the tricuspid valve not closing properly, leading to blood flowing back into the right atrium. Pulmonary hypertension (choice D) is a condition characterized by high blood pressure in the arteries of the lungs.
2. Which of the following is a challenge the profession of nursing faced?
- A. Nursing contributing to the stigma of AIDS in the 1980s out of fear.
- B. Nursing practice flourishing in field hospitals during the Korean War with abundant supplies and equipment.
- C. Many nurses feeling frustrated with the lack of independent functioning after the Vietnam War.
- D. A decline in the number of hospice nurses due to ethical dilemmas.
Correct answer: C
Rationale: The correct answer is C. After the Vietnam War, many nurses felt frustrated with the lack of independent functioning when they returned home. This challenge was faced by the profession of nursing as nurses who functioned independently in mobile hospital units during the war found themselves restricted in their practice upon returning. Choices A, B, and D are incorrect because they do not address the specific challenge of lack of independent functioning faced by nurses after the Vietnam War.
3. A toddler has minimal change nephrotic syndrome (MCNS) and 3+ pitting edema. Which intervention should the nurse include in the plan of care?
- A. Encourage an increased fluid intake for the toddler
- B. Place the child in an Airborne infection isolation room
- C. Increase the toddler's dietary sodium intake
- D. Administer corticosteroids to the toddler
Correct answer: D
Rationale: In managing minimal change nephrotic syndrome (MCNS) in children with pitting edema, corticosteroids are the mainstay of treatment. Corticosteroids help reduce inflammation and decrease proteinuria, addressing the underlying cause of MCNS. Therefore, the nurse should prioritize administering the prescribed corticosteroids to the toddler as part of the plan of care.
4. Which of the following best describes the concept of shared decision-making in healthcare?
- A. The process by which patients make healthcare decisions on their own
- B. A collaborative process that allows patients and providers to make healthcare decisions together
- C. A method for providers to dictate treatment plans to patients
- D. The use of evidence-based guidelines to make healthcare decisions
Correct answer: B
Rationale: The correct answer is B. Shared decision-making in healthcare involves a collaborative process between patients and providers to make healthcare decisions together. This approach considers the patient's preferences, values, and the best available evidence to reach a decision that aligns with the patient's goals. Choice A is incorrect because shared decision-making does not involve patients making decisions on their own. Choice C is incorrect as it describes a paternalistic approach where providers dictate treatment plans to patients without involving them in the decision-making process. Choice D is incorrect as it refers to the use of evidence-based guidelines, which is important but not the sole focus of shared decision-making.
5. A client has a new prescription for Warfarin. Which of the following instructions should the nurse include?
- A. Monitor for signs of bleeding.
- B. Avoid foods high in vitamin K.
- C. Expect to have increased urination.
- D. Take the medication with an antacid.
Correct answer: A
Rationale: The correct instruction for a client starting Warfarin is to monitor for signs of bleeding. Warfarin is an anticoagulant that increases the risk of bleeding; therefore, it is crucial for the client to watch for any signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stools, or unusual bleeding from gums or nose. If any of these signs occur, the client should promptly report them to their healthcare provider for further evaluation and management. Choices B, C, and D are incorrect because avoiding foods high in vitamin K is related to other medications like Coumadin, increased urination is not a common side effect of Warfarin, and taking Warfarin with an antacid can potentially interfere with its absorption.
