Which information about a patient who is receiving cisatracurium (Nimbex) to prevent asynchronous breathing with the positive pressure ventilator requires action by the nurse?

The patient has no cough reflex when suctioned.

The patient's oxygen saturation is 90% to 93%

The patient does not respond to voice.

No sedative is ordered for the patient

Answer and Explanation

The Correct Answer is D

D Sedatives are typically administered alongside neuromuscular blockers to ensure the patient's comfort and prevent awareness during mechanical ventilation.

A The absence of a cough reflex when suctioned is expected in a patient receiving cisatracurium (Nimbex) because it is a neuromuscular blocking agent that induces paralysis. Cisatracurium inhibits skeletal muscle movement, including the muscles involved in coughing.

B An oxygen saturation between 90% to 93% is within an acceptable range for a patient in this condition.

C The lack of response to voice may indicate that the patient is sedated or experiencing effects from the neuromuscular blocking agent. However, since the patient is receiving cisatracurium to prevent asynchronous breathing with the positive pressure ventilator, it's expected that the patient will not respond to voice due to the medication-induced paralysis.

Correct Answer is A

Explanation

A. Pacemaker spikes before each QRS complex: This is the correct answer. In a client with a ventricular pacemaker, the pacemaker spikes should precede each QRS complex on the ECG strip. This indicates that the pacemaker is appropriately stimulating the ventricles to depolarize and initiate a heartbeat. The

presence of pacemaker spikes before each QRS complex signifies that the pacemaker is functioning properly and effectively pacing the ventricles.

B. Pacemaker spikes occurring after each QRS complex would suggest a malfunction or inappropriate timing of the pacemaker. In this scenario, the pacemaker would not be pacing the ventricles as intended. This would be an abnormal finding and would require further assessment and intervention.

C. Pacemaker spikes preceding each P wave would suggest pacing of the atria rather than the ventricles. This would indicate a different type of pacemaker (atrial pacemaker) or inappropriate pacing settings for a ventricular pacemaker. In either case, it would be considered abnormal for a ventricular pacemaker and would require evaluation and possibly reprogramming of the pacemaker.

D. Pacemaker spikes occurring with each T wave would be an abnormal finding and would suggest interference or oversensing by the pacemaker. This could lead to inappropriate pacing or dysrhythmias. It would require further investigation and correction to ensure proper pacemaker function.

A. Cardiac disease B. Renal insufficiency C. Stroke D. Familial hypercholesterolemia E. Atrial fibrillation F. Isolated systolic hypertension

Correct Answer is ["A","B","C","E"]

Explanation

A. Chronic hypertension is a significant risk factor for the development of various cardiac diseases, including coronary artery disease, left ventricular hypertrophy, heart failure, and arrhythmias. The increased workload on the heart caused by hypertension can lead to myocardial remodeling, impaired cardiac function, and ultimately heart disease.

B. Chronic hypertension can cause damage to the kidneys over time, leading to renal insufficiency or chronic kidney disease. The elevated blood pressure damages the delicate blood vessels in the kidneys, impairing their ability to filter waste products and regulate fluid and electrolyte balance. Persistent hypertension can ultimately lead to kidney dysfunction and renal failure.

C. Hypertension is a major risk factor for the development of stroke, particularly ischemic stroke (caused by a blockage in a blood vessel supplying the brain) and hemorrhagic stroke (caused by bleeding into the brain). Chronic hypertension can damage blood vessels in the brain, leading to the formation of blood clots or weakening of vessel walls, increasing the risk of stroke.

E. Chronic hypertension is a significant risk factor for the development of atrial fibrillation, a type of irregular heart rhythm characterized by rapid and chaotic electrical activity in the upper chambers of the heart (atria). The structural changes in the heart caused by hypertension, such as left atrial enlargement and fibrosis, can predispose individuals to atrial fibrillation.

D. Familial hypercholesterolemia is a genetic disorder characterized by high levels of LDL cholesterol in the blood. While chronic hypertension itself does not directly cause familial hypercholesterolemia, hypertension and hypercholesterolemia are often comorbid conditions that contribute to cardiovascular risk. Both conditions can lead to atherosclerosis, increasing the risk of heart disease and stroke.

F. Isolated systolic hypertension refers to elevated systolic blood pressure with normal diastolic blood pressure. While isolated systolic hypertension itself is a manifestation of hypertension, it is not a direct result of end-organ damage. However, if left untreated, isolated systolic hypertension can lead to complications such as stroke, heart failure, and kidney disease, which are consequences of end-organ damage from chronic hypertension.
