A nurse is preparing to administer dabigatran to a client who has atrial fibrillation. The nurse should explain that the purpose of this medication is which of the following?

To slow the response of the ventricles to the fast atrial impulses

To dissolve clots in the bloodstream

To reduce the risk of stroke in clients who have atrial fibrillation

To convert atrial fibrillation to sinus rhythm

Answer and Explanation

The Correct Answer is C

Choice A Reason: This is incorrect because dabigatran does not aﬀect the electrical activity of the heart or the conduction system. It does not slow down the ventricular response to the atrial impulses.

Choice B Reason: This is incorrect because dabigatran does not dissolve existing clots in the bloodstream. It only prevents new clots from forming.

Choice C Reason: This is correct because dabigatran reduces the risk of stroke in clients who have atrial fibrillation by preventing clot formation and reducing blood viscosity. Dabigatran is an anticoagulant medication that prevents the formation of blood clots in the heart and blood vessels. Atrial fibrillation is a condition where the atria beat irregularly and rapidly, which can cause blood to pool and clot in the heart chambers. These clots can travel to the brain and cause a stroke. Dabigatran reduces the risk of stroke by preventing clot formation and reducing blood viscosity.

Choice D Reason: This is incorrect because dabigatran does not restore normal sinus rhythm in clients who have atrial fibrillation. It does not aﬀect the heart rate or rhythm.

Correct Answer is A

Explanation

Choice A Reason: This is correct because the carotid pulse is the most accessible and reliable pulse to check during CPR for an adult client. The carotid pulse is the most accessible and reliable pulse to check during CPR for an adult client. The carotid pulse is located on the side of the neck, near the trachea. The nurse should use two fingers to palpate the carotid pulse for at least 5 seconds and no more than 10 seconds.

Choice B Reason: This is incorrect because the popliteal pulse is located behind the knee and is not easily palpable during CPR.

Choice C Reason: This is incorrect because the radial pulse is located on the wrist and may not be detectable during CPR due to low blood pressure or peripheral vasoconstriction.

Choice D Reason: This is incorrect because the apical pulse is located on the chest and requires a stethoscope to auscultate. The nurse should not interrupt chest compressions or ventilations to listen to the apical pulse during CPR.

A. The client can follow simple motor commands. B. The client opens his eyes when spoken to. C. The client is unconscious. D. The client is unable to make vocal sounds.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because the client's best motor response is 5, which means he can localize pain, not follow commands.

Choice B Reason: This is incorrect because the client's eye opening response is 3, which means he opens his eyes to pain, not to speech.

Choice C Reason: This is correct because the client's GCS score is 13, which indicates a severe impairment of consciousness. The GCS is a tool used to assess the level of consciousness of a person who has a head injury. The GCS score ranges from 3 to 15, with lower scores indicating lower levels of consciousness. A GCS score of 8 or less indicates coma. The client's GCS score is 3 + 5 + 5 = 13, which is above the coma threshold, but still indicates a severe impairment of consciousness. The other choices are not consistent with the client's GCS score.

Choice D Reason: This is incorrect because the client's best verbal response is 5, which means he can orient himself to person, place, and time, not that he is unable to make vocal sounds.
