Critical Care Nursing Cardiac Questions Questions

Question 1 of 5

Following insertion of a central venous catheter, the nurse obtains a stat chest x-ray film to verify proper catheter placement. The radiologist reports to the nurse: �The tip of the catheter is located in the superior vena cava.� What is the best inter pretation of these results by the nurse?

Correct Answer: C

Rationale: The correct answer is C: The distal tip of the catheter is in the appropriate position. Rationale: 1. The superior vena cava is a desirable location for a central venous catheter tip placement as it is close to the heart for rapid medication delivery. 2. Catheter tip in the superior vena cava allows for proper venous return and minimizes the risk of complications. 3. The nurse does not need to remove or adjust the catheter if the tip is in the superior vena cava. 4. Advancing the catheter into the pulmonary artery (option D) would be incorrect as it can lead to serious complications. Incorrect choices: A: Incorrect because placement in the superior vena cava is acceptable. B: Incorrect as placement in the superior vena cava does not increase the risk of ventricular dysrhythmias. D: Incorrect as advancing the catheter into the pulmonary artery is unnecessary and risky.

Question 2 of 5

A new nurse has recently joined the ICU from a different hospital, which had a much stricter policy regarding visiting hours. She expresses concern about the impact of open visiting hours on patient well-being. Which of the following would be the best explanation for the purpose of open visiting hours? Select all that apply.

Correct Answer: B

Rationale: The correct answer is B: To strengthen the relationship between the family and health care provider. Rationale: 1. Open visiting hours encourage family involvement in care, fostering a partnership between healthcare providers and families. 2. Family support can positively impact patient outcomes and satisfaction. 3. It allows families to be updated on the patient's condition and involved in decision-making. 4. Strengthening the relationship can lead to better communication and trust between all parties. Summary of Incorrect Choices: A: Open visiting hours may disrupt rest and quiet, but the primary purpose is not to provide rest. C: Open visiting hours do not aim to control the number of visitors but rather encourage family involvement. D: While open visiting hours may not provide an entirely undisturbed environment, the focus is on improving family-provider relationships.

Question 3 of 5

The patient diagnosed with acute respiratory distress synd rome (ARDS) would exhibit which symptom?

Correct Answer: A

Rationale: The correct answer is A because in ARDS, there is a severe impairment in gas exchange leading to hypoxemia. Decreasing PaO2 levels despite increased FiO2 administration indicate poor oxygenation, a hallmark of ARDS. Elevated alveolar surfactant levels (Choice B) do not directly correlate with ARDS pathophysiology. Increased lung compliance with increased FiO2 administration (Choice C) is not characteristic of ARDS, as ARDS leads to decreased lung compliance. Respiratory acidosis associated with hyperventilation (Choice D) is not a typical finding in ARDS, as hyperventilation is usually present in an attempt to compensate for hypoxemia.

Question 4 of 5

The nurse is caring for a postoperative patient with chroni c obstructive pulmonary disease (COPD). Which assessment would be a cue to the patient developing postoperative pneumonia?

Correct Answer: B

Rationale: The correct answer is B: Change in sputum characteristics. This is a cue for postoperative pneumonia in a COPD patient because it can indicate an infection in the lungs. Postoperative pneumonia is a common complication in patients with COPD due to impaired lung function and weakened immune system. Other choices are incorrect: A) Bradycardia is not a specific indicator of postoperative pneumonia. C) Hypoventilation and respiratory acidosis can be seen in patients with COPD but are not specific to postoperative pneumonia. D) Pursed-lip breathing is a coping mechanism for patients with COPD and is not directly related to postoperative pneumonia.

Question 5 of 5

The family members of a patient who has just been admitted to the intensive care unit (ICU) with multiple traumatic injuries have just arrived in the ICU waiting room. Which action should the nurse take next?

Correct Answer: A

Rationale: The correct answer is A: Explain ICU visitation policies and encourage family visits. This is the best course of action because it prioritizes the needs of the family members by providing them with information on visitation policies and encouraging them to visit the patient. This helps establish communication, support, and involvement in the patient's care. It also respects the family's emotional needs during a challenging time. Choices B, C, and D are incorrect: B: Immediately taking the family members to the patient's bedside may overwhelm them and disrupt the patient's care. C: Describing the patient's injuries and care being provided should be done in a more controlled environment to ensure the family's understanding and emotional readiness. D: Inviting the family to a multidisciplinary care conference may be premature without first addressing their immediate concerns and providing support.
