Question 1 of 5
A nurse is caring for a client who has a pulmonary embolism and has a new order for enoxaparin 1.5 mg/kg/dose to be administered subcutaneously every 12 hours. The client weighs 176 pounds. How many mg should the nurse administer per dose? (Round to the nearest whole number)
Correct Answer: C
Rationale: The correct answer is 120 mg. Convert 176 pounds to kilograms (176 / 2.2 = 80 kg). Calculate the dose: 80 kg × 1.5 mg/kg = 120 mg. This matches the provided correct answer, so option C (120 mg) is correct.
Question 2 of 5
A nurse is teaching a client who has emphysema about self-management strategies. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: B
Rationale: Pursed-lip breathing slows exhalation, preventing airway collapse and improving oxygenation. High-calorie diets, abdominal breathing in prone position, and avoiding flu shots are not optimal strategies.
Question 3 of 5
The nurse is providing education to a client on ways to prevent the development of a pulmonary embolism. Which of the following statements would require further teaching?
Correct Answer: A
Rationale: Crossing the legs increases the risk of venous stasis and clot formation, requiring further teaching. Quitting smoking, staying hydrated, and exercising are appropriate preventive measures.
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
A nurse is teaching a class about sleep disorders. The nurse should include that which of the following conditions can cause obstructive sleep apnea (OSA)?
Correct Answer: D
Rationale: Enlarged tonsils are correct. They can block the airway, causing OSA. Heart failure and opioid overdose are linked to central sleep apnea, and brainstem injury affects respiratory drive but not OSA directly.
