A nurse is caring for a client who has heart failure.
The nurse administered furosemide 60 mg IV bolus 30 min earlier. For which of the following findings should the nurse notify the provider?
BUN 15 mg/dL.
The client reports difficulty hearing.
Potassium 3.8 mEq/L.
The client reports dizziness upon standing.
The Correct Answer is B
Furosemide is a diuretic that is used to treat heart failure by reducing fluid retention and lowering blood pressure. It can cause some side effects, such as increased urination, thirst, dry mouth, headache, dizziness, nausea, and electrolyte imbalance.
Choice A is wrong because BUN (blood urea nitrogen) is a measure of kidney function and a normal range is 7 to 20 mg/dL.
A BUN of 15 mg/dL is not a cause for concern and does not indicate any adverse effect of furosemide.
Choice C is wrong because potassium is an electrolyte that is important for nerve and muscle function and a normal range is 3.5 to 5.0 mEq/L.
Potassium of 3.8 mEq/L is within the normal range and does not indicate any adverse effect of furosemide. However, furosemide can cause low potassium levels (hypokalemia) in some cases, so the nurse should monitor the client’s potassium levels regularly and advise the client to eat foods rich in potassium, such as bananas, oranges, and potatoes.
Choice D is wrong because dizziness upon standing is a common side effect of furosemide and does not require immediate notification of the provider. However, the nurse should instruct the client to rise slowly from a sitting or lying position to prevent falls and to drink enough fluids to prevent dehydration.
Choice B is correct because difficulty hearing or hearing loss is a rare but serious side effect of furosemide that may indicate ototoxicity (damage to the inner ear). This can be irreversible if not treated promptly and may affect the client’s quality of life and safety. The nurse should notify the provider immediately if the client reports difficulty hearing or any other signs of ototoxicity, such as ringing in the ears (tinnitus) or vertigo (a sensation of spinning). The provider may need to adjust the dose of furosemide or switch to another diuretic that is less ototoxic.

Correct Answer is B
Explanation
This is because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so a central venous catheter is usually required. TPN should only be used when the intestine is unavailable or unable to absorb nutrients.
Choice A is wrong because a midline catheter is a type of peripheral catheter that can only be used for solutions with low or moderate osmolarity, not for TPN.
Choice C is wrong because subcutaneous administration is not a route for delivering TPN, which requires intravenous infusion.
Choice D is wrong because intraosseous administration is an emergency route for delivering fluids and drugs when intravenous access is not available, not for TPN.
Correct Answer is A
Explanation
Raloxifene is a medication used to prevent and treat osteoporosis in postmenopausal women.
Osteoporosis is a condition that causes bones to become thin and weak, increasing the risk of fractures.
Raloxifene belongs to a class of drugs called selective estrogen receptor modulators (SERMs), which mimic the effects of estrogen on bone density. Choice B is wrong because raloxifene may increase the risk of deep-vein thrombosis (DVT), a type of blood clot that forms in a vein deep in the body. DVT can cause pain, swelling, and redness in the affected limb, and can lead to serious complications such as pulmonary embolism (PE), a blood clot in the lung.
Raloxifene should not be used by people who have or had DVT or PE. Choice C is wrong because raloxifene is not used to treat urinary tract infection (UTI), an infection that affects the bladder, kidneys, or ureters. UTI can cause symptoms such as burning or pain when urinating, frequent or urgent urination, blood in the urine, or fever.
UTI is usually treated with antibiotics.
Choice D is wrong because raloxifene is not used to treat hypothyroidism, a condition that occurs when the thyroid gland does not produce enough thyroid hormone.
Thyroid hormone regulates the body’s metabolism, growth, and development. Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, dry skin, hair loss, or depression.
Hypothyroidism is usually treated with synthetic thyroid hormone replacement.
