Critical Care Nursing Cardiac Questions Questions

Question 1 of 5

The nurse is assessing a child's weight and height during a clinic visit prior to starting school. The nurse plots the child's weight on the growth chart and notes that the child's weight is in the 95th percentile for the child's height. What action should the nurse take?

Correct Answer: A

Rationale: The correct answer is A: Question the type and quantity of foods eaten in a typical day. When a child's weight is in the 95th percentile for their height, it indicates possible overweight or obesity. To address this, the nurse should assess the child's dietary habits to identify any unhealthy eating patterns contributing to excess weight. By questioning the type and quantity of foods eaten, the nurse can provide appropriate guidance on nutrition and healthy eating habits. Summary: B: Encouraging additional snacks may further contribute to weight gain and is not recommended without knowing the current eating habits. C: Recommending a high intake of whole milk may increase calorie intake and potentially worsen the weight concern. D: Assessing for signs of poor nutrition, such as a pale appearance, is important but not directly addressing the weight concern in this scenario.

Question 2 of 5

When assisting with the placement of a pulmonary artery (PA) catheter, the nurse notes that the catheter is correctly placed when the monitor shows a:

Correct Answer: D

Rationale: Step-by-step rationale for Answer D being correct: 1. PA catheter measures PA pressures. 2. PAWP reflects left atrial pressure. 3. Correct placement shows typical PAWP tracing. 4. PA pressure waveform (A) is not specific to PAWP. 5. Systemic arterial pressure tracing (B) is unrelated. 6. Systemic vascular resistance tracing (C) is not monitored by PA catheter.

Question 3 of 5

The patient is admitted to the unit with the diagnosis of rhabdomyolysis. The patient is started on intravenous (IV) fluids and IV mannitol. What action by the nurse is best?

Correct Answer: B

Rationale: The correct answer is B: Assess the patient’s lungs. Rhabdomyolysis can lead to acute kidney injury due to myoglobin release from damaged muscle cells. IV fluids and mannitol are given to prevent kidney damage by promoting myoglobin excretion. Assessing the patient’s lungs is crucial to monitor for potential complications such as acute respiratory distress syndrome (ARDS) which can occur as a result of rhabdomyolysis. This assessment helps to ensure early detection and prompt intervention if respiratory issues arise. Summary of Incorrect Choices: A: Assess the patient’s hearing - This is not directly related to rhabdomyolysis or its treatment. C: Decrease IV fluids once the diuretic has been administered - Decreasing IV fluids can exacerbate kidney injury in rhabdomyolysis. D: Give extra doses before giving radiological contrast agents - Mannitol is not routinely given before radiological contrast agents in the context of rhabdomyolysis management.

Question 4 of 5

An unresponsive 79-year-old is admitted to the emergency department (ED) during a summer heat wave. The patient’s core temperature is 105.4°F (40.8°C), blood pressure (BP) 88/50, and pulse 112. The nurse initially will plan to:

Correct Answer: A

Rationale: The correct answer is A: Apply wet sheets and a fan to the patient. This is the initial treatment for hyperthermia to aid in lowering the body temperature. Wet sheets help in evaporative cooling, while a fan enhances heat loss through convection. This approach is crucial in managing heat-related illnesses quickly. Choices B, C, and D are incorrect as they do not directly address the urgent need to reduce the patient's elevated core temperature. Providing O2, IV fluids, or acetaminophen can be considered later in the management, but the priority is to rapidly lower the body temperature in a hyperthermic patient to prevent further complications.

Question 5 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.

The nurse cites evidence-based practice as a rationale for a patient care decision. What isthe best description of evidence-based practice?
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?
