Extract:
Question 1 of 5
A client takes the morning dose of 10 units of insulin aspart at 0800. At what time would the nurse assess for hypoglycemia?
Correct Answer: B
Rationale: Insulin aspart peaks around 1-2 hours after administration, making 0930 (1.5 hours post-dose) the optimal time to assess for hypoglycemia. 0830 is too early, and 1030 or 1130 are beyond the peak risk period.
Question 2 of 5
The physician ordered cephalexin 4 mg/kg PO Q6 hours. The medication is available at 250 mg/5 mL. The client weighs 245 pounds. What is the correct dose to be administered every 6 hours? (Round the answer to the nearest whole number. Do not use a trailing zero.)
Correct Answer: 9
Rationale: Client weight: 245 lbs ÷ 2.2 = 111.36 kg. Dose: 4 mg/kg × 111.36 = 445.44 mg. Available: 250 mg/5 mL, so 445.44 ÷ (250/5) = 8.91 mL, rounded to 9 mL.
Question 3 of 5
The nursing student is writing a problem list for a client just admitted with a total small bowel obstruction. Which problem should the instructor ask?
Correct Answer: B
Rationale: Bowel obstruction risks gastrointestinal tissue perfusion due to potential ischemia. Fluid volume excess, infection, and pain are secondary concerns.
Question 4 of 5
The nurse is planning a teaching session for a patient with a duodenal ulcer. Which instructions are MOST important to include in the teaching? (SELECT ALL THAT APPLY)
Correct Answer: A,D,E
Rationale: Avoiding aspirin and ibuprofen prevents gastrointestinal irritation, and smoking cessation aids healing. Coffee and dairy can worsen ulcer symptoms by increasing acid.
Question 5 of 5
The nurse evaluates that an obese client understands the need for a healthy weight loss pattern by indicating an intention to lose:
Correct Answer: C
Rationale: Aiming for 1 pound per week is a healthy, sustainable weight loss goal, reducing risks like muscle loss and nutritional deficiencies. Rapid weight loss (5 or 10 pounds per week, or 3 pounds every 5 days) is unsafe and unsustainable.
