Extract:
Question 1 of 5
A nurse is caring for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: A humidifier prevents nasal dryness from prolonged oxygen use. A is unsafe due to flammability risks, B disrupts oxygen delivery, and C is incorrect as the cannula is nasal, not oral.
Question 2 of 5
The nurse is caring for a client who is receiving isoniazid and rifampin. Which of the following statements by the client would need further follow up?
Correct Answer: D
Rationale: Yellow skin suggests jaundice, a sign of hepatotoxicity from isoniazid or rifampin, requiring immediate follow-up. A is expected with rifampin, B is positive, and C is less urgent if improving.
Question 3 of 5
A nurse is caring for a client who is postoperative hip arthroplasty and has a new prescription for enoxaparin 1mg/kg/dose subcutaneous every 12 hr. The client weighs 95 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Convert pounds to kilograms: 95 lbs ÷ 2.2 lbs/kg = 43.18 kg. Calculate dose: 1 mg/kg × 43.18 kg = 43.18 mg, rounded to 43.2 mg. This ensures accurate dosing for anticoagulation post-surgery.
Question 4 of 5
A nurse is reviewing blood pressure classifications with a group of nurses at an in-service meeting. Which of the following should the nurse include as a risk factor for the development of hypertension?
Correct Answer: B
Rationale: Obstructive sleep apnea contributes to hypertension by causing repeated episodes of hypoxia, sympathetic nervous system activation, and increased vascular resistance. High potassium intake helps lower blood pressure, HDL of 70 mg/dL is protective, and benazepril treats hypertension, not causes it.
Question 5 of 5
A nurse is caring for a client who is taking enalapril (Vasotec). Which of the following outcomes indicates a therapeutic effect of the medication?
Correct Answer: D
Rationale: Enalapril, an ACE inhibitor, lowers blood pressure by preventing vasoconstriction and reducing fluid retention. It does not directly treat claudication or affect cholesterol levels.
