Which of the following should be avoided for clients taking ACE Inhibitors?
Food high in potassium.
Low sodium diet.
Adequate fluid intake.
Foods low in potassium.
The Correct Answer is A
Food high in potassium should be avoided for clients taking ACE inhibitors. ACE inhibitors are drugs that block the conversion of angiotensin I to angiotensin II, which is a potent vasoconstrictor and also stimulates the secretion of aldosterone. Aldosterone is a hormone that increases the reabsorption of sodium and water and the excretion of potassium in the kidneys. By inhibiting angiotensin II, ACE inhibitors lower blood pressure and reduce the loss of potassium. However, this can also lead to hyperkalemia, which is a high level of potassium in the blood that can cause cardiac arrhythmias and muscle weakness. Therefore, clients taking ACE inhibitors should limit their intake of foods that are rich in potassium, such as bananas, oranges, tomatoes, potatoes, spinach, beans, nuts, and salt substitutes.
Choice B is wrong because a low sodium diet is recommended for clients taking ACE inhibitors.
A low sodium diet can help lower blood pressure and reduce fluid retention, which are beneficial effects for clients with hypertension, heart failure, or chronic kidney disease. A low-potassium diet should aim for potassium intake of less than 50 or 75 mmol/day and sodium intake of less than 60 mmol/day for hypertensive patients with chronic kidney disease.
Choice C is wrong because adequate fluid intake is not contraindicated for clients taking ACE inhibitors.
Adequate fluid intake can help prevent dehydration and maintain kidney function, especially in patients with diabetes or nephropathy. However, excessive fluid intake may worsen heart failure or edema in some patients, so fluid intake should be individualized and monitored according to the patient’s condition and response to therapy.
Choice D is wrong because foods low in potassium are not harmful for clients taking ACE inhibitors.
Foods low in potassium do not affect the serum potassium level or the risk of hyperkalemia in clients taking ACE inhibitors. However, foods low in potassium may not provide enough dietary potassium for normal cellular functions, so a balanced diet that includes moderate amounts of potassium-rich foods is advisable.

Correct Answer is B
Explanation
PT stands for prothrombin time, which is a measure of how long it takes the blood to clot.
INR stands for international normalized ratio, which is a way of standardizing the PT results across different laboratories.
Warfarin is a blood thinner that works by inhibiting the production of vitamin K-dependent clotting factors in the liver.
Therefore, warfarin prolongs the PT and increases the INR.The PT/INR test is used to monitor the effectiveness of warfarin therapy and adjust the dose accordingly.
Choice A is wrong because PTT stands for partial thromboplastin time, which is another measure of blood clotting time, but it reflects the activity of different clotting factors than PT.PTT is used to monitor heparin therapy, not warfarin therapy.
Choice C is wrong because aPTT stands for activated partial thromboplastin time, which is a variation of PTT that uses an activator to speed up the clotting time.Like PTT, aPTT is used to monitor heparin therapy, not warfarin therapy.
Choice D is wrong because ACT stands for activated clotting time, which is a measure of the whole blood clotting time.ACT is used to monitor high-dose heparin therapy during certain procedures, such as cardiac bypass surgery or angioplasty.
The normal ranges for these tests may vary depending on the laboratory and the method used, but generally, they are:
• PT: 10 to 13 seconds
• INR: 0.8 to 1.2 (without warfarin) or 2.0 to 3.0 (with warfarin)
• PTT: 25 to 35 seconds
• aPTT: 30 to 40 seconds
• ACT: 70 to 120 seconds
Correct Answer is B
Explanation
The nurse should contact the provider before administering furosemide because the patient has a low serum potassium level of 2.8 mEq/L, which is below the normal range of 3.5 to 5.0 mEq/L.Furosemide is a diuretic that can cause potassium loss and worsen hypokalemia, which can lead to cardiac arrhythmias, muscle weakness, and fatigue. The nurse should also monitor the patient’s blood pressure, weight, and urine output, as furosemide can lower blood pressure and cause dehydration.
Choice A. Administer medication is wrong because the nurse should not give furosemide without checking with the provider first, as it could be harmful to the patient with low potassium.
Choice C. Hold medication is wrong because the nurse should not withhold furosemide without a valid reason or an order from the provider, as it could cause fluid overload and worsen the patient’s condition.
Choice D. Give potassium supplement is wrong because the nurse should not give potassium supplement without an order from the provider, as it could cause hyperkalemia or interact with other medications.
