A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis.

Available is heparin 10,000 units/mL.

How many mL of heparin should the nurse administer? (Round the answer to the nearest) tenth.

Use a leading zero if it applies.

Do not use a trailing zero.) mL.

This is the priority for the nurse to report to the provider because cefuroxime is a cephalosporin antibiotic that can cause serious or life-threatening allergic reactions in people who are allergic to penicillin. The nurse should not administer cefuroxime to this client until the provider is notified and an alternative antibiotic is prescribed.

Choice A is wrong because the client has a BUN level of 18 mg/dL, which is within the normal range of 7 to 20 mg/dL.

This does not indicate any renal impairment or adverse reaction to cefuroxime.

Choice B is wrong because the client reports a history of nausea with cefuroxime, which is a common side effect of this drug.

The nurse should instruct the client to take cefuroxime with food to reduce nausea, but this is not a priority to report to the provider.

Choice D is wrong because the client takes aspirin daily, which does not interact with cefuroxime.

The nurse should monitor the client for any signs of bleeding or bruising while taking aspirin, but this is not a priority to report to the provider.

This is because a weight gain of 2.5 kg (5 Ib) in 2 days indicates a worsening of heart failure and fluid retention, which may require an adjustment of the diuretic dose or other medications.

The provider should be informed of this change as soon as possible to prevent further complications.

Choice A is wrong because teaching the client about foods low in sodium is not the first action the nurse should take.

While a low-sodium diet is important for heart failure patients, it is not an urgent intervention and it does not address the immediate problem of fluid overload.

Choice B is wrong because determining medication adherence by the client is not the first action the nurse should take.

While it is important to assess if the client is taking furosemide as prescribed, it is not an urgent intervention and it does not rule out other causes of fluid retention, such as renal impairment or disease progression.

Choice C is wrong because encouraging the client to dangle the legs while sitting in a chair is not the first action the nurse should take.

While this may help reduce edema in the lower extremities, it does not address the underlying cause of fluid overload and it may worsen pulmonary congestion by increasing venous return to the heart.
