Palpating the radial pulse in the right arm is not the most appropriate choice following a cardiac catheterization with a left antecubital insertion site. While it is contralateral to the insertion site, the brachial pulse is preferred over the radial pulse for assessing circulation in the arm, as it is more proximal and can provide a better indication of arterial flow from the catheterization site.

Palpating the radial pulse in the left arm, which is ipsilateral to the insertion site, is not recommended. This is because the radial pulse may be diminished or absent due to arterial occlusion or spasm caused by the catheterization procedure.

Palpating the brachial pulse in the left arm is also not recommended. Since the catheterization was performed on the left side, there is a risk of arterial occlusion or spasm, which could affect the accuracy of the pulse assessment in the left arm.

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

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

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.

Reason: This is incorrect because this client has signs of brain death, such as severe head injuries, low respiratory rate, and unresponsiveness. The nurse should tag this client as black, which means deceased or expectant.

Reason: This is incorrect because this client has non-life-threatening injuries, such as a simple fracture and scratches. The nurse should tag this client as green, which means minor or delayed care.

Reason: This is incorrect because this client has minor injuries and is able to walk around. The nurse should tag this client as green, which means minor or delayed care.

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.

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

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.

Reason: This is incorrect because shortening of P-wave duration is not a sign of hyperkalemia or its reversal. P-wave duration reflects the time it takes for the atria to depolarize and contract.

Reason: This is incorrect because restoration of QRS complex amplitude is not a sign of hyperkalemia or its reversal. QRS complex amplitude reflects the voltage or strength of the ventricular depolarization and contraction.

Reason: This is incorrect because the widening of the QRS complex is a sign of hyperkalemia, not its reversal. Widening of the QRS complex reflects the delay or impairment of ventricular depolarization and contraction.

Reason: This is incorrect because cleaning the wound is not a priority when the client is bleeding profusely. Cleaning the wound can also dislodge any clots that have formed and increase bleeding.

Reason: This is incorrect because applying a tourniquet is a last resort when direct pressure fails to stop bleeding. A tourniquet can cause tissue damage, nerve injury, and infection if applied incorrectly or for too long.

Reason: This is incorrect because elevating the limb and applying ice are not effective actions to stop bleeding from a wound. Elevating the limb can reduce blood flow to the injured area, but it does not compress the blood vessels or prevent blood loss. Applying ice can cause vasoconstriction, but it can also damage the skin and tissues if applied for too long.

Reason: This is incorrect because these values indicate respiratory alkalosis, which is caused by hyperventilation or excess loss of carbon dioxide (PaCO2). Respiratory alkalosis increases the blood pH and decreases the HCO3- level.

Reason: This is incorrect because these values indicate metabolic alkalosis, which is caused by excess intake or retention of bases or loss of acids. Metabolic alkalosis increases the blood pH and the HCO3- level.

Reason: This is incorrect because these values indicate respiratory acidosis, which is caused by hypoventilation or excess retention of carbon dioxide (PaCO2). Respiratory acidosis decreases the blood pH and increases the HCO3- level.

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

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.

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.
