A nurse in a coronary care unit is admitting a patient who has had CPR following a cardiac arrest.

The patient is receiving lidocaine IV at 2 mg/min.
When the patient asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?

Relieves pain.

Slows intestinal motility.

Dissolves blood clots.

Prevents dysrhythmias.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Lidocaine does not primarily serve to relieve pain when administered intravenously. It is primarily used as an antiarrhythmic agent.

Choice B rationale

Lidocaine does not slow intestinal motility. This is not one of its primary actions.

Choice C rationale

Lidocaine does not dissolve blood clots. It is not an anticoagulant.

Choice D rationale

Lidocaine prevents dysrhythmias. It is an antidysrhythmic medication that delays the conduction in the heart and reduces the automaticity of heart tissue.

Correct Answer is A

Explanation

Choice A rationale

A negative rubella titer indicates that the patient does not have immunity to the rubella virus. Therefore, the patient would need a rubella vaccination after delivery to prevent future infection.

Choice B rationale

A negative rubella titer does not necessarily mean that the patient is not currently infected with rubella. It simply means that the patient does not have immunity to the virus.

Choice C rationale

A negative rubella titer indicates that the patient is not immune to the rubella virus, not that they are immune.

Choice D rationale

While the patient does need a rubella vaccination, it is not typically given during pregnancy due to the theoretical risk to the fetus. Instead, it is usually given after delivery.

A. Decreased libido is an adverse effect of the medication. B. Avoid drinking grapefruit juice when taking this medication. C. PSA levels will increase while taking this medication. D. Expect to see a response from the medication within one week.

Correct Answer is A

Explanation

Choice A rationale

Finasteride, a medication used to treat benign prostatic hypertrophy, can cause several side effects, including a decrease in libido or sexual desire.

Choice B rationale

There’s no specific interaction between finasteride and grapefruit juice. Therefore, patients don’t need to avoid grapefruit juice when taking this medication.

Choice C rationale

Finasteride can actually cause a decrease in PSA (prostate-specific antigen) levels. If a patient is having a PSA test, they should tell their doctor they are taking finasteride because it can affect the results.

Choice D rationale

It may take up to six months or more to see the full effects of finasteride. Therefore, patients should not expect to see a response within one week.
