Question 1 of 5
A client has an order for Demerol 75 mg and atropine 0.4 mg IM as a preoperative medication. The Demerol vial contains 50 mg/mL, and atropine is available 0.4 mg/mL. How many milliliters will the nurse administer in total?
Correct Answer: C
Rationale: Demerol: 75 mg ÷ 50 mg/mL = 1.5 mL. Atropine: 0.4 mg ÷ 0.4 mg/mL = 1 mL.
Total = 1.5 mL + 1 mL = 2.5 mL.
Question 2 of 5
The nurse recognizes that which of the following would be most appropriate to wear when providing direct care to a client with a cough?
Correct Answer: A
Rationale: A mask is the most appropriate PPE to prevent transmission of respiratory infections from a client with a cough, as it protects against droplet spread.
Question 3 of 5
A client weighing 150 pounds has received burns over 50% of his body at 1200 hours. Using the Parkland formula, calculate the expected amount of fluid that the client should receive by 2000 hours.
Correct Answer: B
Rationale: Parkland formula: 4 mL × kg × % TBSA. Weight = 150 lb ÷ 2.2 = 68 kg. 4 × 68 × 50 = 13,600 mL total. Half (6,800 mL) is given in the first 8 hours (1200 to 2000).
Question 4 of 5
If both parents are carriers of the defective gene for a disease with an autosomal recessive inheritance, what percentage chance does each child have of inheriting the gene from both parents and developing the disorder? Report your answer using a whole number.
Correct Answer: 25
Rationale: Autosomal recessive inheritance: Each parent has a 50% chance of passing the defective gene, so the child's chance is 0.5 X 0.5 = 0.25 or 25%.
