Extract:
Question 1 of 5
A nurse is planning to calculate a client's cardiac output. Which of the following data should the nurse obtain to calculate the cardiac output?
Correct Answer: D
Rationale: Heart rate is one of the key components in calculating cardiac output, along with stroke volume. Cardiac output is calculated by multiplying the heart rate (beats per minute) by the stroke volume (the amount of blood pumped by the heart per beat). This provides the total amount of blood the heart pumps per minute.
Question 2 of 5
A nurse is caring for a client who came to the emergency department reporting chest pain. The provider suspects a myocardial infarction. While waiting for the troponin levels report, the client asks what this blood test will show. Which of the following explanations should the nurse provide the client?
Correct Answer: C
Rationale: Troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart. It is a highly sensitive and specific marker for myocardial injury, making it a critical test for diagnosing a myocardial infarction.
Question 3 of 5
A nurse is caring for a child who has Addison's disease. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Cortisol replacement therapy is essential for children with Addison's disease because the condition involves insufficient production of cortisol, a hormone vital for stress response and metabolism. Teaching parents about this therapy is a key nursing intervention to ensure proper management of the disease.
Question 4 of 5
A nurse is planning care for a client who has deep vein thrombosis of the lower leg. Which of the following interventions should the nurse include in the plan of care?
Correct Answer: B
Rationale: Keeping the client's affected leg elevated while in bed helps reduce swelling and promotes venous return, which is important in managing DVT.
Question 5 of 5
A nurse is assessing the elastic bandage on the stump of a client who had a right below-the-knee amputation. Which of the following findings should the nurse identify as a complication?
Correct Answer: B
Rationale: Pitting edema around the stump dressing is a complication. This could indicate poor circulation, infection, or fluid retention, which requires prompt assessment and intervention to prevent further complications.
