A nurse is preparing to administer heparin 15,000 units every 12 hr subcutaneously to a client who weighs 80 kg. Available is 10,000 units/mL. How many mL should the nurse administer with each dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
The correct answer is 1.5 mL. Here is the explanation:
To calculate the amount of mL to administer, the nurse should use the following formula:
mL = (units ordered / units available) x mL available
Plugging in the values from the question, we get:
mL = (15,000 / 10,000) x 1
mL = 1.5 x 1
mL = 1.5
Therefore, the nurse should administer 1.5 mL of heparin with each dose.

Correct Answer is B
Explanation
Choice A: This is incorrect. Potassium 4.0 mEq/L is a normal value and does not indicate heart failure.
Choice B: This is correct. Brain natriuretic peptide (BNP) is a hormone that is released by the heart when it is stretched or overloaded. A high level of BNP indicates that the heart is working harder than normal and may have heart failure. A normal BNP level is less than 100 pg/mL, so 275 pg/mL is elevated and suggestive of heart failure.
Choice C: This is incorrect. Sodium 140 mEq/L is a normal value and does not indicate heart failure.
Choice D: This is incorrect. Calcium 9.0 mg/dL is a normal value and does not indicate heart failure.
Correct Answer is A
Explanation
Choice A reason: Using analgesia around the clock is an appropriate action. The nurse should follow the principle of prevention rather than rescue when managing pain for a client who has terminal cancer. The nurse should administer analgesics on a regular schedule to maintain a steady level of pain relief and prevent breakthrough pain.
Choice B reason: Applying pain patches each morning and removing them at bedtime is not an appropriate action. The nurse should follow the manufacturer's instructions for applying and removing pain patches. Some patches are designed to be worn for 24 hours, while others are worn for 72 hours. Removing the patches too soon can cause inadequate pain control and withdrawal symptoms.
Choice C reason: Using intramuscular medications to control pain is not an appropriate action. The nurse should avoid using intramuscular route for administering analgesics to a client who has terminal cancer. Intramuscular injections are painful, unreliable, and increase the risk of infection and bleeding. The nurse should use oral, transdermal, or subcutaneous routes whenever possible.
Choice D reason: Decreasing a medication dose if the client develops tolerance is not an appropriate action. The nurse should understand that tolerance is a normal physiological response to long-term opioid use and does not indicate addiction or abuse. The nurse should adjust the medication dose according to the client's level of pain and response to treatment.
