A nurse is reviewing laboratory values of a client with chronic renal failure and discovers the client has a serum potassium of 6.2 mEq/L. Which of the following interventions should the nurse anticipate?
Administering sodium polystyrene sulfonate.
Initiating an IV potassium infusion.
Administering a potassium-sparing diuretic.
Encouraging the client to eat bananas.
The Correct Answer is A
A. Administering sodium polystyrene sulfonate:
This medication removes potassium through the GI tract and is used to treat hyperkalemia.
B. Initiating an IV potassium infusion:
The client already has hyperkalemia; giving potassium would worsen it.
C. Administering a potassium-sparing diuretic:
These medications retain potassium and would further elevate potassium levels.
D. Encouraging the client to eat bananas:
Bananas are high in potassium and should be avoided in hyperkalemia.

Correct Answer is B
Explanation
A. Evaluating the patient's level of pain after medication administration: This is important but comes after the medication is given.
B. Ensuring a bag valve mask (BVM) is at the bedside: Opioids and sedatives depress respiratory drive. Emergency resuscitation equipment (like a BVM) must be ready in case of respiratory compromise.
C. Verification of allergies to medications: Important, but verifying allergies should already be done before administering any meds; not the priority here.
D. Documenting the level of pain before medication administration: Also important, but secondary to safety preparation.
Correct Answer is B
Explanation
A. Bradycardia: Peritonitis is usually associated with tachycardia, not bradycardia.
B. Nausea and vomiting: These are common early signs of peritonitis, often accompanied by abdominal pain and fever.
C. Increased urinary output: Clients with peritoneal dialysis often have reduced kidney function, so urine output is generally decreased, not increased.
D. Hyperactive bowel sounds: Bowel sounds are usually diminished or hypoactive in peritonitis due to inflammation.
