Question 1 of 5
Which goal is a primary objective for a patient who has chronic heart failure (HF)?
Correct Answer: A
Rationale: Maximizing cardiac output is a primary goal for patients with chronic heart failure (HF) because it helps improve tissue perfusion and oxygen delivery to meet the body's demands. It is a crucial aspect of managing heart failure and preventing further complications.
Question 2 of 5
The arterial blood gas (ABG) results for a patient who overdosed on barbiturates are pH = 7.32, PaCO2 = 52, and HCO3 = 23. Which interpretation would the nurse rely on when planning the patient's care?
Correct Answer: C
Rationale: The given ABG results indicate a low pH (acidosis), an elevated PaCO2 (respiratory component), and a normal HCO3 (metabolic component). The low pH and increased PaCO2 suggest respiratory acidosis.
Question 3 of 5
The nurse receives information about the assigned patients during shift report. Which patient would the nurse assess first?
Correct Answer: B
Rationale: A severe headache and vomiting could be indicative of a serious neurological condition such as a stroke, intracranial bleeding, or increased intracranial pressure. This patient needs urgent assessment and intervention to prevent potential complications.
Question 4 of 5
After noting that a patient with leukemia has thrombocytopenia, which action will the nurse plan to take?
Correct Answer: C
Rationale: Inspecting the skin for bruising or petechiae is specific to thrombocytopenia, as petechiae are small, red or purple dots that appear on the skin when platelet count is low, indicating a bleeding tendency.
Question 5 of 5
Which erythrocyte characteristic would the nurse expect to see in the laboratory findings for a patient who has experienced acute blood loss?
Correct Answer: B
Rationale: Normocytic erythrocytes, or normal-sized red blood cells, are usually seen in acute blood loss as the body's initial response doesn't alter the size of red blood cells.
