A client is prescribed oral potassium supplements for hypokalemia. The nurse instructs the client to take the medication:
With food or a full glass of water.
On an empty stomach with a sip of water.
With milk or antacids to prevent irritation.
With grapefruit juice to enhance absorption.
The Correct Answer is A
Oral potassium supplements can cause stomach irritation or laxative effect if taken without enough fluid or food.
Taking the medication with food or a full glass of water can help prevent these side effects and improve absorption.
Choice B is wrong because taking the medication on an empty stomach with a sip of water can increase the risk of stomach irritation or laxative effect and reduce absorption.
Choice C is wrong because taking the medication with milk or antacids can interfere with the absorption of potassium and cause hyperkalemia (high blood potassium levels).
Choice D is wrong because taking the medication with grapefruit juice can also interfere with the absorption of potassium and cause hyperkalemia.
Grapefruit juice can also interact with some medications that affect potassium levels, such as angiotensin-converting enzyme (ACE) inhibitors and potassium- sparing diuretics.

Correct Answer is B
Explanation
Performing hand hygiene before and after handling the dialysis equipment is essential to prevent infection in peritoneal dialysis.
Hand washing and appropriate use of a mask can help avoid peritonitis, which is a serious complication of peritoneal dialysis.
Choice A is wrong because administering antibiotics prophylactically is not recommended for peritoneal dialysis patients, as it can increase the risk of antibiotic resistance and adverse effects.
Choice C is wrong because allowing the client to handle the dialysis equipment independently may increase the risk of contamination and infection.
The client should be supervised and instructed by a nurse on how to use sterile technique when connecting and disconnecting the transfer set.
Choice D is wrong because discontinuing the peritoneal dialysis if the client develops a fever may worsen the client’s condition and lead to fluid overload and electrolyte imbalance.
The client should be evaluated for signs of infection and treated accordingly.
Correct Answer is ["23"]
Explanation
The correct answer is 22.5 mL.
To find the amount of mL, use the formula: (desired dose / available dose) x available volume.
In this case, desired dose = 30 mEq, available dose = 20 mEq, and available volume = 15 mL.
Plug these values into the formula: (30 mEq / 20 mEq) x 15 mL = 22.5 mL.
However, since the instructions say to round to the nearest whole number for adult clients, the final answer is 23 mL.
