Critical Care Nursing Cardiac Questions Questions

Question 1 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 2 of 5

A patient who has experienced blunt abdominal trauma during a motor vehicle collision is complaining of increasing abdominal pain. The nurse will plan to teach the patient about the purpose of:

Correct Answer: B

Rationale: The correct answer is B: Abdominal ultrasonography. This is because ultrasonography is a non-invasive imaging technique that can quickly evaluate for internal injuries such as organ damage or bleeding in patients with blunt abdominal trauma. It is a rapid and effective diagnostic tool to assess the extent of injury and guide further management. Peritoneal lavage (A) is an invasive procedure used in trauma settings to detect intra-abdominal bleeding but is not typically used for teaching purposes. Nasogastric tube placement (C) is used for decompression and drainage in certain conditions but is not relevant for assessing abdominal trauma. Magnetic resonance imaging (MRI) (D) is not typically used as the initial imaging modality for acute trauma due to time constraints and its limited availability in emergency settings.

Question 3 of 5

Following surgery for an abdominal aortic aneurysm, the patient�s central venous pressure (CVP) monitor indicates low pressures. Which action is a priority for the nurse to take?

Correct Answer: B

Rationale: The correct answer is B: Increase the IV fluid infusion per protocol. Low CVP post-abdominal aortic aneurysm surgery could indicate hypovolemia, which requires fluid resuscitation. Increasing IV fluid infusion helps restore intravascular volume, improve tissue perfusion, and prevent hypotension. Administering diuretics (A) would worsen hypovolemia. Documenting (C) is important but not the priority when the patient needs immediate intervention. Elevating the head of the bed (D) may help with venous return but is not the priority over addressing hypovolemia.

Question 4 of 5

The nurse is caring for a patient who has an intra-aortic balloon pump (IABP) following a massive heart attack. When assessing the patient, the nurse notices blood backing up into the IABP catheter. In which order should the nurse take the following actions?

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Ensuring the IABP console is turned off is crucial to prevent further complications and stop potential harm to the patient. 2. By turning off the IABP console, the nurse can halt the pumping action, allowing assessment of the situation without interference. 3. This action takes priority over other steps as it addresses the immediate issue of blood backing up into the IABP catheter. 4. Once the console is turned off, the nurse can proceed with assessing the patient's vital signs, notifying the healthcare provider, and obtaining supplies if needed. Summary of Incorrect Choices: - Option B: Assessing vital signs and orientation is important, but addressing the malfunction of the IABP takes precedence to prevent harm. - Option C: Notifying the healthcare provider is necessary, but first, the immediate issue of blood backing up into the catheter must be addressed. - Option D: Obtaining supplies for a new catheter is premature without first addressing

Question 5 of 5

A 28-year-old patient who has deep human bite wounds on the left hand is being treated in the urgent care center. Which action will the nurse plan to take?

Correct Answer: C

Rationale: The correct answer is C: Teach the patient the reason for the use of prophylactic antibiotics. This is the most important action because human bites can introduce harmful bacteria into the wound, leading to infection. Prophylactic antibiotics help prevent infection in deep human bite wounds. Choice A is incorrect because rabies immune globulin is not indicated for human bite wounds. Choice B is incorrect because suturing human bite wounds can trap bacteria and increase the risk of infection. Choice D is incorrect because keeping the wounds dry is not sufficient; proper wound cleaning and antibiotic treatment are essential in this case.
