A patient taking spironolactone asks about using a salt substitute. What should the nurse explain?

1. ASalt substitutes are fine as long as the patient drinks more water
2. BMost salt substitutes contain potassium and can raise the level too high
3. CSalt substitutes protect against the potassium loss caused by this drug
4. DSalt substitutes are safe because they contain only sodium chloride

1. Aنظام غذائي قليل البروتين
2. Bفرط الإماهة
3. Cفشل الكبد

A urine culture report states "mixed growth of three organisms, likely contamination." What is the nurse's best response?

1. ADiscard the report, because a mixed growth is always normal
2. BRecord the result as a confirmed urinary tract infection
3. CStart treatment for all three organisms with three antibiotics

After a crush injury, a patient's urine dipstick is strongly positive for blood, but microscopy shows almost no red cells. CK is very high. What best explains this?

1. AA kidney stone is scraping the ureter lining
2. BBleeding is coming from the bladder lining
3. CThe sample was contaminated with menstrual blood
4. DMyoglobin from damaged muscle is in the urine

A patient on digoxin has a calcium of 12,1 mg/dL (3,0 mmol/L) and new nausea and a slow pulse. Why is the calcium result important?

1. AHigh calcium blocks digoxin, so the drug stops working
2. BHigh calcium only matters if the potassium is also high
3. CHigh calcium increases the risk of digoxin toxicity
4. DHigh calcium makes the kidneys clear digoxin faster
