The nurse is to administer heparin to a client who weighs 90 pounds. Heparin is ordered as 10,000 units/100mL. The nurse needs to administer a bolus of 40units/kg. How many units would the nurse administer? (Round to the nearest tenth)

Answer and Explanation

The Correct Answer is ["1636.4"]

Convert pounds to kilograms:
- Weight in kilograms = 90 pounds / 2.2 pounds/kg = 40.9090... kg. For practical purposes, we can round to 40.91kg.
Calculate the heparin dose:
- The ordered bolus dose is 40 units/kg.
- Heparin dose = 40.91 kg 40 units/kg = 1636.4 units.
Round to the nearest tenth:
- The heparin dose is 1636.4 units.

= 1636.4 units

Correct Answer is A

Explanation

A. Metformin is correct. The combination of iodinated contrast dye and metformin increases the risk of contrast-induced nephropathy (CIN) and lactic acidosis, especially in clients with pre-existing kidney dysfunction. Metformin should be held before and after the procedure until renal function is reassessed.
B. Nitroglycerin is used for angina and does not interact with contrast dye.
C. Atorvastatin (a statin) is used for cholesterol management and has no significant interaction with contrast dye.
D. Carvedilol (a beta-blocker) is used for heart failure and hypertension but does not increase the risk of contrast-induced kidney injury.

A. Massage the calves every shift. B. Apply elastic compression stockings. C. Perform passive range of motion exercises. D. Assess legs for redness. E. Place pillows under the client's knees when in bed.

Correct Answer is ["B","C","D"]

Explanation

A. Massaging the calves is incorrect. This action can dislodge a deep vein thrombus (DVT), increasing the risk of a pulmonary embolism.
B. Applying elastic compression stockings is correct. These help promote venous return, reducing the risk of blood stasis and clot formation.
C. Performing passive range of motion exercises is correct. These exercises prevent venous stasis, which is a major risk factor for DVT and PE.
D. Assessing legs for redness is correct. Redness, swelling, and warmth can indicate DVT formation, allowing for early intervention before it leads to PE.
E. Placing pillows under the client's knees is incorrect. This can impair circulation and increase the risk of clot formation by promoting venous stasis.
