Critical Care Nursing Cardiac Questions Questions

Question 1 of 5

A 10-year-old female patient in ICU receiving chemotherapy has requested that her dog be allowed to visit her. She is currently sharing a room with another patient. The nurse knows that the hospital does allow for pet visits with owners, but has strict guidelines. Which of the following scenarios is most likely to be permitted?

Correct Answer: A

Rationale: The correct answer is A because it follows the hospital's guidelines for pet visits. It allows the dog to be brought in on a leash, which ensures control and safety during the visit. The 20-minute duration is appropriate to limit potential stress on the patient and other individuals in the room. Additionally, having the father bring the dog in maintains consistency with the hospital's policy of pet visits with owners. Choices B, C, and D are incorrect because they do not adhere to the hospital's guidelines. Choice B allows for an overnight stay, which is typically not permitted due to potential disruptions and hygiene concerns. Choice C mentions vaccinations but overlooks other important factors like leash control and visit duration. Choice D suggests waiting until the girl is moved to a private room, which may not align with the hospital's policy of allowing pet visits with owners.

Question 2 of 5

The nurse is caring for a mechanically ventilated patient an d responds to a high inspiratory pressure alarm. Recognizing possible causes for the alarma, btihrbe.c nomu/rtesset assesses for which of the following? (Select all that apply.)

Correct Answer: B

Rationale: The correct answer is B: Disconnection from the ventilator. This is the correct choice because a high inspiratory pressure alarm can indicate a disconnection, leading to inadequate ventilation and increased pressure in the circuit. This can be a life-threatening situation that requires immediate attention. Explanation of why other choices are incorrect: A: Coughing or attempting to talk - While coughing or talking may affect the patient's ability to ventilate properly, it is not directly related to the high inspiratory pressure alarm. C: Kinks in the ventilator tubing - Kinks in the tubing may cause increased resistance to airflow, but they are more likely to trigger a low pressure alarm rather than a high inspiratory pressure alarm. D: Need for suctioning - Suctioning may be necessary for airway clearance, but it is not directly related to the high inspiratory pressure alarm.

Question 3 of 5

A patient with terminal cancer reports a sudden onset of severe pain. Which intervention should the nurse implement first?

Correct Answer: A

Rationale: The correct answer is A: Assess the patient�s pain using a standardized pain scale. The first step is to assess the severity and nature of the pain to determine the appropriate intervention. This allows the nurse to understand the pain intensity and characteristics, which guides the choice of analgesic and dosing. Administering analgesics (B) without proper assessment can lead to inappropriate treatment. Notifying the healthcare provider (C) is important but assessing the pain should come first. Repositioning the patient (D) may provide comfort but addressing the pain directly is the priority.

Question 4 of 5

A client is admitted to the hospital with a diagnosis of Type 2 diabetes mellitus and influenza. Which categories of illness should the nurse develop goals for the client's plan of care?

Correct Answer: A

Rationale: The correct answer is A: One chronic and one acute illness. This is because Type 2 diabetes mellitus is a chronic condition, while influenza is an acute illness. The nurse should develop goals addressing the management and control of the chronic condition (diabetes) as well as the treatment and recovery from the acute illness (influenza). This approach ensures comprehensive care that considers both the long-term management of the chronic illness and the immediate needs related to the acute illness. Choices B, C, and D are incorrect because they do not address the combination of chronic and acute illnesses presented in the scenario. Choice B focuses solely on two acute illnesses, which overlooks the ongoing management required for the chronic condition. Choice C combines an acute and an infectious illness, but fails to account for the chronic illness component. Choice D involves two chronic illnesses, neglecting the immediate care needed for the acute illness.

Question 5 of 5

Which of the following are physiological effects of positive end-expiratory pressure (PEEP) used in the treatment of acute respiratory distress syndrom e (ARDS)? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A: Increase functional residual capacity. Positive end-expiratory pressure (PEEP) helps increase the functional residual capacity by keeping the alveoli open at the end of expiration. This prevents alveolar collapse, improves ventilation-perfusion matching, and enhances oxygenation. B: Prevent collapse of unstable alveoli - This is incorrect because PEEP actually helps prevent the collapse of all alveoli, not just unstable ones. C: Improve arterial oxygenation - This is partially correct, but the primary mechanism through which PEEP improves oxygenation is by increasing functional residual capacity. D: Open collapsed alveoli - This is incorrect because PEEP helps prevent alveolar collapse rather than actively opening already collapsed alveoli.

A nurse is caring for an elderly man recently admitted to the ICU following a stroke. She assesses his cognitive function using a new cognitive assessment test she learned about in a recent article in a nursing journal. She then brings a cup of water and a straw to the patient because she observes that his lips are dry. Later, she has the patient sit in a wheelchair and takes him to have some blood tests performed. He objects at first, saying that he can walk on his own, but the nurse explains that it is hospital policy to use the wheelchair. That evening, she recognizes signs of an imminent stroke in the patient and immediately pages the physician. Which action taken by the nurse is the best example of evidence-based practice?
