The nurse is caring for a client who is two weeks post-op hip replacement and has a wound infection. The client's admission vital signs are: Temperature 102 F (38.8 C) orally, HR 150/min (rhythm is shown below). Respiratory rate- 22/min, and Blood pressure is 128/72. Based on these assessment findings, the nurse understands that the client:

surgery has caused an episode of supraventricular tachycardia.
is febrile which is causing the heart rate to be elevated.
is in heart failure and the heart rate is elevated to compensate.
probably has a low oxygen saturation causing an increased respiratory rate.
The Correct Answer is B
A. surgery has caused an episode of supraventricular tachycardia: While stress or surgery can trigger arrhythmias, the ECG shown demonstrates a sinus tachycardia pattern (narrow QRS complexes with identifiable P waves before each QRS), not supraventricular tachycardia (SVT), which typically has a very rapid, regular rhythm often without visible P waves.
B. is febrile which is causing the heart rate to be elevated: The client has a temperature of 102°F (38.8°C), which can increase metabolic demand and lead to sinus tachycardia. Fever is a common and expected cause of elevated heart rate, especially when accompanied by infection, such as the client’s post-op wound infection.
C. is in heart failure and the heart rate is elevated to compensate: There is no evidence from the scenario (no dyspnea, crackles, edema, or reduced BP) that supports heart failure. The elevated HR is more directly related to the fever and infection, not cardiac decompensation.
D. probably has a low oxygen saturation causing an increased respiratory rate: The respiratory rate is slightly elevated (22/min), but there is no mention of hypoxia or oxygen saturation levels. Tachycardia secondary to hypoxia would require clinical indicators of respiratory distress or desaturation, which are not demonstrated.

Correct Answer is C
Explanation
A. A 60-year-old woman with cardiac dysrhythmias post myocardial infarction. Her HR is 39 & irregular, BP 147/65: Although her heart rate is low, carvedilol is commonly used post-MI to reduce mortality, especially in patients with dysrhythmias. However, caution is warranted, and dosage adjustments or withholding may be necessary due to bradycardia.
B. A 55-year-old woman with HTN due to renal failure from chronic pyelonephritis. HR 92. BP 145/72: This client has stable vitals, and carvedilol can be safely used to help manage hypertension. Renal impairment requires monitoring, but it is not a contraindication if renal function is closely followed.
C. A 78-year-old man with a history of hyperlipidemia & cardiac dysfunction. He is in 3rd degree heart block. HR 42. BP 92/65: Carvedilol is contraindicated in clients with 2nd or 3rd degree heart block without a functioning pacemaker. It can worsen bradycardia and conduction delays, making its use unsafe in this client without rhythm control support.
D. A 49-year-old male, BMI 36, history of type 2 diabetes & HTN. HR 105, BP 158/92: This client is hypertensive and tachycardic, both of which carvedilol can help manage. Although diabetes requires careful monitoring for hypoglycemia, there is no contraindication in this scenario.
Correct Answer is D
Explanation
A. Assist the client from the stretcher to a wheelchair: Immediately after electroconvulsive therapy (ECT), the client is still recovering from anesthesia and may experience confusion, drowsiness, or muscle weakness. Transferring the client prematurely poses a fall risk and is not appropriate as the first action.
B. Orient the client and offer reassurance: While reorientation and reassurance are important aspects of post-ECT care, safety and physiological stability must be assessed first. This action should follow an initial assessment of vital signs and level of consciousness.
C. Encourage the client to drink some fluids: Offering fluids too soon after ECT is inappropriate because the client may have impaired swallowing reflexes from anesthesia or sedation. Ensuring the airway is clear and the client is fully alert must precede oral intake.
D. Assess vital signs and orient client to the PACU environment: The priority after any procedure involving anesthesia is to assess vital signs to ensure hemodynamic stability and monitor for complications. Once stable, the nurse can begin to orient the client, which is often needed after ECT due to temporary disorientation or memory lapses.
