RN Registered Nurse 5

Question 1

A patient with chronic kidney disease (CKD) is at risk for hyperkalemia. Which food should the nurse instruct the patient to avoid?

Accepted Answer

Bananas and oranges

Answer

Bananas and oranges are high-potassium foods that can worsen hyperkalemia in CKD patients whose kidneys cannot excrete excess potassium.

Question 2

A nurse is caring for a patient in alcohol withdrawal. Which medication does the nurse anticipate the provider will order to prevent seizures?

Accepted Answer

Lorazepam

Answer

Benzodiazepines such as lorazepam are the first-line treatment for alcohol withdrawal because they cross-react with GABA receptors and prevent withdrawal seizures.

Question 3

A nurse is caring for a patient with a chest tube connected to water-seal drainage. The nurse observes continuous bubbling in the water-seal chamber. What does this indicate?

Accepted Answer

Air leak in the system or lung

Answer

Continuous (not intermittent) bubbling in the water-seal chamber indicates an air leak from either the patient's lung or the drainage system connections.

Question 4

A patient with heart failure is prescribed furosemide 40 mg IV. Which laboratory value should the nurse assess before and after administration?

Accepted Answer

Serum potassium

Answer

Furosemide is a loop diuretic that causes significant potassium wasting; hypokalemia can lead to dangerous cardiac dysrhythmias.

Question 5

A nurse is providing discharge teaching to a patient prescribed warfarin. Which statement by the patient indicates a need for further teaching?

Accepted Answer

'I will take ibuprofen instead of acetaminophen for pain.'

Answer

NSAIDs like ibuprofen inhibit platelet aggregation and displace warfarin from protein-binding sites, significantly increasing bleeding risk.
