Use a leading zero if it applies.
Do not use a trailing zero.) mL.
The Correct Answer is ["0.4"]
To calculate the amount of heparin to administer, use the formula:
mL of heparin=units available units ordered×1mL available
Substituting the values given in the question, we get:
mL of heparin=100004000×11=0.4
Therefore, the nurse should administer 0.4 mL of heparin.
Normal ranges for heparin therapy vary depending on the condition being treated and the laboratory method used to measure APTT.
A general range is 60 to 80 seconds or 1.5 to 2.5 times the control value.

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.
Correct Answer is D

Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease1 and should be used with caution in patients with hepatic impairment or active liver disease. Alcohol use disorder can cause liver damage and increase the risk of acetaminophen toxicity.
Choice A is wrong because hepatitis B vaccine within the last week is not a contraindication for receiving acetaminophen.
There is no evidence that acetaminophen interferes with the immune response to the vaccine or causes adverse effects.

Acetaminophen is mainly metabolized by the liver and has minimal renal excretion.
However, patients with chronic kidney disease should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
Choice C is wrong because diabetes mellitus is not a contraindication for receiving acetaminophen.
Acetaminophen does not affect blood glucose levels or interact with oral antidiabetic drugs.
However, patients with diabetes mellitus should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
