A 63-year-old male with obesity, diabetes, and hypertension is hospitalized with COVID-19 pneumonia. Vitals: T 102.4°F, HR 110 bpm, RR 28/min, BP 134/86 mmHg, SpO₂ 88% on room air. Which nursing action is most appropriate to implement first? 

A client taking digoxin reports nausea, blurred vision, and dizziness. The heart rate is 48 bpm, and the digoxin level is 2.8 ng/mL. What should the nurse do first?

A 72-year-old client with heart failure is on carvedilol, furosemide, and lisinopril. The client reports less swelling and better sleep but occasional dizziness. Vitals: BP 108/64 mmHg, HR 58 bpm, weight down 3 lb. Which finding indicates that therapy is effective? 

A nurse is monitoring a client receiving furosemide (Lasix) 80 mg IV twice daily for heart failure. The client’s morning laboratory results are as follows: Sodium: 136 mEq/L (Normal: 135–145) Potassium: 2.8 mEq/L (Normal: 3.5–5.0) BUN: 32 mg/dL (Normal: 7–20) Creatinine: 1.8 mg/dL (Normal: 0.6–1.2) Blood pressure: 92/56 mmHg Heart rate: 112 bpm Which nursing action is the priority?

A nurse is reviewing the medical record of a client diagnosed with osteoarthritis. Which finding would the nurse expect based on the underlying disease process? Assessment Findings: Pain and stiffness in knees and hips Crepitus with movement Joint pain worsens with activity and improves with rest Laboratory Results: ESR: 12 mm/hr (Normal: 0–20) CRP: 0.6 mg/dL (Normal:

A nurse is reviewing laboratory and diagnostic results for a client with suspected myasthenia gravis. The provider explains that the client’s acetylcholine receptor antibody test is positive and electromyography shows decreased muscle response with repetitive stimulation. Based on these findings, which statement best describes the underlying mechanism of the client’s symptoms?

Consider the following IP problem: maximize Z = 5×1 + x2, subject to: – x1 + 2×2 ≤ 4 x1 – x2 ≤ 1 4×1 + x2 ≤ 12 x1 ≥ 0, x2 ≥ 0 x1, x2 are integers. a)Solve this problem graphically (i.e., report the optimal values of the objective function and the decision variables). (20 points) b)Solve the LP relaxation graphically. Round this solution to the nearest integer solution and check whether it is feasible. (20 points)
