Vati Green Light Comprehensive Current Testing Questions And Correct Answers Top-Rated A+.

VATI GREEN LIGHT COMPREHENSIVE CURRENT TESTING QUESTIONS AND CORRECT ANSWERS TOP-RATED A+. Question 1 A nurse is caring for a client who is 4 hr postoperative following a total hip arthroplasty. Which finding requires the nurse to intervene immediately? A. Pain rated 6/10 B. Urine output of 35 mL/hr C. Oxygen saturation of 88% on room air D. Temperature of 37.7°C (99.9°F) ANSWERS: C. Oxygen saturation of 88% on room air Rationale: An oxygen saturation of 88% indicates hypoxemia and requires immediate assessment and intervention. The nurse should assess respiratory status, apply oxygen as prescribed or according to protocol, and determine the cause. Moderate postoperative pain and a temperature of 37.7°C can occur following surgery. Urine output of 35 mL/hr is generally acceptable for an adult, although it should continue to be monitored. Question 2 A nurse is assessing a client who has heart failure. Which finding is the strongest indication that the client's condition is worsening? A. Weight gain of 2 kg (4.4 lb) over 3 days B. Heart rate of 88/min C. Blood pressure of 128/76 mm Hg D. Mild fatigue after ambulation ANSWERS: A. Weight gain of 2 kg (4.4 lb) over 3 days Rationale: Rapid weight gain indicates fluid retention and is an important early manifestation of worsening heart failure. A gain of approximately 2 kg over several days suggests significant fluid accumulation. The other findings are not as concerning in isolation. Question 3 A nurse is preparing to administer digoxin to a client. The client's apical pulse is 54/min. Which action should the nurse take? A. Administer the medication as prescribed B. Recheck the pulse after the client ambulates C. Hold the medication and notify the provider D. Administer half of the prescribed dose ANSWERS: C. Hold the medication and notify the provider Rationale: Digoxin can decrease the heart rate. An adult apical pulse below 60/min is generally a reason to withhold digoxin and notify the provider. The nurse should not independently reduce the prescribed dose. Question 4 A client receiving a continuous IV heparin infusion has an aPTT that is significantly above the therapeutic range. Which action should the nurse anticipate? A. Increasing the infusion rate B. Holding or reducing the infusion according to protocol C. Administering vitamin K D. Administering aspirin ANSWERS: B. Holding or reducing the infusion according to protocol Rationale: An excessively elevated aPTT indicates excessive anticoagulation and increases the risk for bleeding. The heparin infusion is generally held or decreased according to the facility's protocol. Vitamin K reverses warfarin, not heparin. Aspirin would further increase bleeding risk. Question 5 A nurse is assessing a client who has a potassium level of 6.3 mEq/L (6.3 mmol/L). Which finding should the nurse anticipate? A. Peaked T waves B. Flat T waves C. U waves D. Prolonged QT interval ANSWERS: A. Peaked T waves Rationale: Hyperkalemia can cause characteristic ECG changes, especially tall, peaked T waves. Severe hyperkalemia can progress to widened QRS complexes, ventricular dysrhythmias, and cardiac arrest. Flat T waves and U waves are more associated with hypokalemia. Question 6 A nurse is caring for a client with chronic obstructive pulmonary disease who has an oxygen saturation of 91%. Which prescription should the nurse question? A. Encourage pursed-lip breathing B. Administer oxygen at 2 L/min via nasal cannula C. Administer oxygen at 15 L/min via nonrebreather mask continuously D. Encourage controlled coughing ANSWERS: C. Administer oxygen at 15 L/min via nonrebreather mask continuously Rationale: Oxygen should be carefully titrated in clients with COPD, especially those at risk for chronic carbon dioxide retention. A nonrebreather at 15 L/min provides a very high concentration of oxygen and is not appropriate for routine management of a stable client with an oxygen saturation of 91%. Controlled oxygen therapy and prescribed target saturations are preferred. Question 7 A client with diabetes mellitus is confused, diaphoretic, and shaky. The client's blood glucose is 52 mg/dL (2.9 mmol/L), and the client is awake and able to swallow. Which action should the nurse take first? A. Administer regular insulin B. Give 15 g of rapid-acting carbohydrate C. Administer glucagon IM D. Give a high-protein meal ANSWERS: B. Give 15 g of rapid-acting carbohydrate Rationale: The client is experiencing symptomatic hypoglycemia but is conscious and able to swallow. The nurse should give approximately 15 g of rapid-acting carbohydrate, such as glucose tablets or juice, and recheck the glucose after approximately 15 min. Glucagon is appropriate when the client cannot safely take oral carbohydrate.
