A nurse is caring for a client who is receiving heparin therapy. If the client requires a reversal of the effects of heparin, which of the following medications should the nurse expect the provider to prescribe?

Atropine

Vitamin K

Vitamin B12

Protamine

Answer and Explanation

The Correct Answer is D

A. Atropine. Atropine is an anticholinergic medication used to treat bradycardia and reduce secretions before surgery. It has no effect on reversing anticoagulation caused by heparin and would not be an appropriate treatment for heparin overdose.

B. Vitamin K. Vitamin K is used as an antidote for warfarin toxicity, as it helps produce clotting factors that warfarin inhibits. However, it does not reverse the effects of heparin, which works by enhancing the activity of antithrombin to prevent clot formation.

C. Vitamin B12. Vitamin B12 is essential for red blood cell production and neurological function, primarily used to treat conditions like pernicious anemia. It does not have any role in reversing the anticoagulant effects of heparin and would not be beneficial in this situation.

D. Protamine. Protamine sulfate is the specific antidote for heparin overdose. It binds to heparin, neutralizing its anticoagulant effects and preventing excessive bleeding. Protamine is administered intravenously in cases of heparin toxicity or when urgent reversal is needed, such as before surgery or in cases of uncontrolled bleeding.

Correct Answer is B

Explanation

A. Assist the client to a left lateral position. The preferred position for vaginal suppository insertion is the dorsal recumbent (lying on the back with knees bent) or the lithotomy position. The left lateral position is typically used for rectal suppository administration, not vaginal medication insertion.

B. Insert the suppository along the posterior wall of the vaginal canal. The suppository should be inserted along the posterior vaginal wall, as this allows for proper absorption and helps ensure the medication remains in place. The client should be advised to lie down for at least 10-15 minutes after insertion to prevent the suppository from slipping out.

C. Apply a light coating of petroleum jelly to the suppository. Petroleum jelly should never be used as it can interfere with medication absorption and may break down the suppository. If lubrication is needed, a small amount of water-soluble lubricant (e.g., KY Jelly) can be applied to facilitate insertion.

D. Put on sterile gloves before handling the suppository. Clean gloves (not sterile gloves) are sufficient for vaginal suppository administration. The vaginal canal is not a sterile environment, so strict aseptic technique is not required. However, proper hand hygiene and glove use are essential to prevent contamination and infection.

Correct Answer is ["3"]

Explanation

Convert pounds to kilograms:

Conversion factor: 1 kg = 2.2 lb

66 lb / 2.2 lb/kg = 30 kg

Calculate the dose to administer:

Dose (mg) = Weight (kg) × Dosage (mg/kg)

=30 kg × 0.1 mg/kg

= 3 mg
