Question 1 of 5
The nurse is caring for a diabetic client who had a Coronary Angiography two hours ago. Which of the following orders should the nurse question?
Correct Answer: C
Rationale: Administering metformin should be questioned. Metformin is contraindicated within 48 hours of receiving contrast dye because of the risk of lactic acidosis, especially in clients with impaired renal function. Having the client lay flat for 4 hours is appropriate to prevent bleeding from the arterial puncture site. Monitoring the site for bleeding and hematoma formation is necessary to detect complications. Administering aspirin is appropriate to prevent clot formation post-procedure.
Question 2 of 5
A nurse is providing teaching to a client who has angina pectoris and a new prescription for nitroglycerin sublingual tablets. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: D
Rationale: Calling 911 if pain persists after taking 3 nitroglycerin tablets 5 minutes apart is correct. Persistent pain suggests a possible myocardial infarction, requiring immediate medical intervention. The other options deviate from the standard protocol for nitroglycerin use.
Question 3 of 5
The nurse and unlicensed assistive personnel (UAP) are caring for an elderly client diagnosed with emphysema. Which nursing tasks could be delegated to the UAP to improve gas exchange? (Select All that Apply)
Correct Answer: C,D,E
Rationale: Encouraging deep breathing exercises (
C), recording pulse oximeter readings (
D), and keeping the head of bed elevated (E) can be delegated to a UAP to improve gas exchange. Assessing consciousness and auscultating breath sounds require nursing judgment.
Question 4 of 5
The nurse is to administer heparin to a client who weighs 90 pounds. Heparin is ordered as 10,000 units/100mL. The nurse needs to administer a bolus of 40units/kg. How many units would the nurse administer? (Round to the nearest tenth)
Correct Answer: C
Rationale: The correct answer is 1636.4 units. Convert 90 pounds to kilograms (90 / 2.2 = 40.91 kg). Calculate the dose: 40.91 kg × 40 units/kg = 1636.4 units. This matches the provided correct answer, so option C (1636.4 units) is correct.
Question 5 of 5
A nurse is caring for a client who reports a new onset of severe chest pain. Which of the following actions should the nurse take to determine if the client is experiencing a myocardial infarction?
Correct Answer: D
Rationale: Performing a 12-lead ECG is the most important diagnostic tool for identifying myocardial infarction. It provides real-time evidence of ischemic changes, such as ST-segment elevation or depression, confirming or ruling out an MI. Checking blood pressure, auscultating heart tones, and assessing pain radiation are supportive but not definitive for diagnosing an MI.
