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.)

Choice A rationale:

Nicotine nasal spray delivers a rapid dose of nicotine to the bloodstream, which can help reduce cravings and withdrawal symptoms. The recommended dose is 1 to 2 sprays in each nostril every hour, up to 40 sprays per day. The client should not sniff, swallow, or inhale while spraying, and should avoid contact with the eyes and skin.

Choice B rationale:

The nicotine patch should be changed every 24 hours, not every other day. The patch provides a steady dose of nicotine through the skin, which can help prevent cravings and withdrawal symptoms. The client should apply the patch to a clean, dry, and hairless area of the skin, and rotate the site of application daily.

Choice C rationale:

the nicotine gum should be chewed for about 30 minutes, not 10 minutes, before spitting it out. The gum releases nicotine into the mouth, which is then absorbed into the bloodstream through the mucous membranes. The client should chew the gum slowly until a peppery taste or tingling sensation occurs, then park it between the cheek and gum until the taste or sensation fades, then repeat the process.

Choice D rationale:

The client should avoid drinking beverages for 15 minutes before and during sucking on a nicotine lozenge, not just while sucking on it. The lozenge dissolves in the mouth and releases nicotine, which is then absorbed into the bloodstream through the mucous membranes. Drinking beverages can interfere with the absorption of nicotine and reduce the effectiveness of the lozenge.

Choice A rationale:

Hyperglycemia is not typically associated with an acute infusion reaction to amphotericin B.

Choice B rationale:

A dry cough is a common side effect of amphotericin B, but it is not an indicator of an acute infusion reaction.

Choice C rationale:

Pedal edema is not a typical sign of an acute infusion reaction to amphotericin B.

Choice D rationale:

Fever, along with other symptoms like chills, fever, nausea, and vomiting, can be indicative of an acute infusion reaction to amphotericin B. It may require stopping the infusion and providing appropriate treatment.
