Extract:
Question 1 of 5
A nurse is caring for a client who develops a pulmonary embolism. Which of the following interventions should the nurse implement first?
Correct Answer: C
Rationale: Administering oxygen therapy is correct. A pulmonary embolism impairs oxygenation, and immediate oxygen administration improves delivery to vital organs. Morphine, cardiac monitoring, and IV fluids are secondary priorities.
Question 2 of 5
A nurse is caring for a client with a diagnosis of left-sided heart failure. The nurse expects what assessment findings associated with left-sided heart failure? (Select All that Apply.)
Correct Answer: C,D,E
Rationale: Crackles in the lungs (
C), confusion (
D), and exertional dyspnea (E) are expected. Left-sided heart failure causes pulmonary congestion (crackles, dyspnea) and reduced cerebral perfusion (confusion). Ascites and leg edema are associated with right-sided heart failure.
Question 3 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 4 of 5
Which of the following is a complication of heart failure?
Correct Answer: A
Rationale: Pleural effusion is a common complication of heart failure. Increased pulmonary circulation pressure causes fluid accumulation in the pleural space. Infection, asthma, and hemorrhage are not direct complications of heart failure.
Question 5 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.
