The prescriber orders furosemide 80 mg for a patient who has been retaining extra fluid after surgery. The nurse notes the following: BP of 142/88 (lying) and 108/60 (sitting); daily weight of 154 lb, a 1-lb drop from day before; serum potassium of 2.8 mEq/L.
What should the nurse do?
Administer medication.
Contact provider.
Hold medication
Give potassium supplement
The Correct Answer is B
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.

Correct Answer is C
Explanation
Bile acid-binding resins are cholesterol-lowering agents that bind to bile acids in the intestine and prevent their reabsorption. This reduces the amount of bile acids available for cholesterol synthesis in the liver, which lowers the levels of LDL cholesterol in the blood. However, bile acids are also needed for the absorption of fat-soluble vitamins A, D, E, and K.Therefore, patients taking bile acid-binding resins may require supplements of these vitamins to prevent deficiency.
Choice A is wrong because nicotinic acid, or niacin, is a B vitamin that can lower cholesterol by limiting the production of fats in the liver.It does not affect the absorption of fat-soluble vitamins.
Choice B is wrong because nitroglycerin is not a cholesterol-lowering agent, but a vasodilator that relaxes the blood vessels and improves blood flow.It has no effect on fat-soluble vitamin absorption.
Choice D is wrong because beta blockers are not cholesterol-lowering agents, but drugs that lower blood pressure and heart rate by blocking the effects of adrenaline.They have no effect on fat-soluble vitamin absorption.
Correct Answer is B
Explanation
Lifestyle is the greatest contributing factor that can lead to many diseases, especially noncommunicable diseases (NCDs) such as cardiovascular diseases, cancers, chronic respiratory diseases and diabetes.According to the World Health Organization (WHO), NCDs are responsible for 74% of all deaths worldwide, and they share four major risk factors: tobacco use, physical inactivity, the harmful use of alcohol and unhealthy diets.These modifiable behaviours increase the risk of metabolic risk factors such as raised blood pressure, increased blood glucose, elevated blood lipids and obesity, which can lead to NCDs.
Choice A is wrong because trauma is not a factor that can lead to many diseases, but rather a result of injuries or accidents that damage the body.Trauma can cause acute or chronic conditions, such as infections, bleeding, fractures, organ failure or post-traumatic stress disorder, but it is not a common cause of NCDs.
Choice C is wrong because congenital means present at birth or inherited.
Congenital diseases are caused by genetic mutations or environmental factors that affect the development of the fetus.
Some examples of congenital diseases are Down syndrome, cystic fibrosis, congenital heart defects and spina bifida.
Congenital diseases are not the greatest contributing factor to many diseases because they are relatively rare and often detected early.
Choice D is wrong because genetics refers to the inherited traits from parents that influence the risk of developing certain diseases.
Genetics can play a role in some NCDs, such as cancers, diabetes and some cardiovascular diseases, but it is not the only or the most important factor.
Genetics interacts with environmental and lifestyle factors to determine the likelihood of developing a disease.
Therefore, genetics alone cannot lead to many diseases.
