In addition to assessing peripheral pulses and auscultating the patient’s heart and lung sounds, which action will be implemented by the nurse before a cardiac catheterization? Select all that apply. One, some, or all responses may be correct.

Choice A: Increased Respiratory Rate

Fluid overload, also known as hypervolemia, can lead to an increased respiratory rate. This occurs because the excess fluid in the body can accumulate in the lungs, leading to pulmonary congestion and edema. As a result, the body attempts to compensate by increasing the respiratory rate to improve oxygenation and remove excess carbon dioxide. Normal respiratory rate for adults is typically between 12-20 breaths per minute. An increased respiratory rate above this range can indicate fluid overload.

Choice B: Increased Heart Rate

An increased heart rate, or tachycardia, is another common finding in clients with fluid overload. The heart has to work harder to pump the excess fluid throughout the body, leading to an increased heart rate. This is a compensatory mechanism to maintain adequate cardiac output and tissue perfusion. Normal resting heart rate for adults is between 60-100 beats per minute. A heart rate above this range can be indicative of fluid overload.

Choice C: Increased Blood Pressure

Fluid overload can also result in increased blood pressure, or hypertension. The excess fluid in the bloodstream increases the volume of blood that the heart has to pump, leading to higher pressure within the arteries. This can strain the cardiovascular system and lead to complications if not managed properly. Normal blood pressure is typically around 120/80 mmHg. Blood pressure readings consistently above this range can suggest fluid overload.

Choice D: Increased Hematocrit

Increased hematocrit is not typically associated with fluid overload. Hematocrit is the proportion of red blood cells in the blood. In cases of fluid overload, the hematocrit level is usually decreased due to the dilutional effect of the excess fluid. Therefore, this choice is incorrect.

Choice E: Increased Temperature

Increased temperature is not a common finding in fluid overload. Fever or elevated body temperature is more commonly associated with infections or inflammatory conditions. Fluid overload does not typically cause an increase in body temperature. Therefore, this choice is incorrect.

Choice A Reason:

Continuing to monitor is the most appropriate action in this scenario. The patient has a regular heart rhythm and a heart rate of 60 beats per minute, which is within the normal range for sinus bradycardia. The PR interval is 0.20 seconds, which is at the upper limit of normal. The patient’s vital signs are stable, with a blood pressure of 118/68 mm Hg, a respiratory rate of 16 breaths per minute, and a temperature of 98.8°F (37°C). There are no signs of hemodynamic instability or symptoms that would necessitate immediate intervention. Therefore, ongoing monitoring is sufficient to ensure the patient’s condition remains stable.

Choice B Reason:

Administering clonidine is not appropriate in this situation. Clonidine is an antihypertensive medication that can lower blood pressure and heart rate. Given that the patient’s blood pressure and heart rate are within normal ranges, administering clonidine could potentially cause hypotension and bradycardia, leading to adverse effects. Therefore, clonidine is not indicated for this patient.

Choice C Reason:

Administering atropine is not necessary for this patient. Atropine is used to treat symptomatic bradycardia, where the heart rate is abnormally slow and causing symptoms such as dizziness, hypotension, or syncope. In this case, the patient’s heart rate is 60 beats per minute, which is within the normal range for sinus bradycardia, and there are no symptoms indicating the need for atropine. Therefore, atropine is not required.

Choice D Reason:

Administering digoxin is also not appropriate. Digoxin is a cardiac glycoside used to treat heart failure and certain types of arrhythmias, such as atrial fibrillation. It can slow the heart rate and increase the force of cardiac contractions. In this scenario, the patient does not have any indications for digoxin therapy, such as heart failure or atrial fibrillation, and their heart rate is already within the normal range. Therefore, digoxin is not indicated.
