Question 1

A nurse is caring for a client with chronic kidney disease (CKD) who has a potassium level of 6.2 mEq/L. Which dietary instruction is most important?

Accepted Answer

Avoid foods high in potassium such as potatoes and tomatoes

Answer

Hyperkalemia in CKD requires restricting high-potassium foods like potatoes, tomatoes, and bananas to prevent life-threatening cardiac arrhythmias.

Question 2

A postoperative client develops a respiratory rate of 6 breaths/min and is difficult to arouse after receiving IV morphine. What is the priority nursing action?

Accepted Answer

Administer naloxone (Narcan) as ordered

Answer

Naloxone rapidly reverses opioid-induced respiratory depression and is the priority intervention to restore adequate ventilation.

Question 3

A nurse assesses a client with left-sided heart failure. Which finding is most consistent with this diagnosis?

Accepted Answer

Crackles in the lung bases

Answer

Left-sided heart failure causes pulmonary congestion, leading to fluid accumulation in the alveoli and crackles on auscultation.

Question 4

A nurse is preparing to administer a blood transfusion. After hanging the blood, the client develops chills, back pain, and dark urine within 15 minutes. What should the nurse do first?

Accepted Answer

Stop the transfusion and keep the IV line open with normal saline

Answer

These signs indicate an acute hemolytic reaction; the transfusion must be stopped immediately and the IV kept patent with NS to prevent renal failure.
