Question 1 of 5
Which explanation will the nurse give a patient with non-Hodgkin lymphoma about the purpose of a planned lumbar puncture?
Correct Answer: D
Rationale: A lumbar puncture in non-Hodgkin lymphoma is used to detect central nervous system involvement by examining cerebrospinal fluid for lymphoma cells.
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
A patient reports leg pain that awakens the patient at night. The patient reports that the same pain develops in the legs when they are elevated and disappears when the legs are dangled. Which condition would the nurse suspect?
Correct Answer: A
Rationale: Peripheral arterial disease causes leg pain worsened by elevation and relieved by dangling, due to reduced blood flow from arterial narrowing.
Question 4 of 5
A patient who smokes reports chest pain while at rest. Which condition would the nurse suspect the patient is experiencing?
Correct Answer: C
Rationale: Prinzmetal angina, also known as variant angina, typically occurs at rest due to coronary artery spasms, which aligns with the patient's symptoms of chest pain at rest.
Question 5 of 5
The nurse is teaching a patient about the administration of liquid iron supplements. Which response by the patient indicates the need for additional teaching?
