Question 1 of 5

The nurse is teaching the parents of an infant with osteogenesis imperfecta. The nurse should explain the need for:

Correct Answer: B

Rationale: Osteogenesis imperfecta causes brittle bones, so careful handling is critical to prevent fractures in infants with this condition.

Question 2 of 5

A client's blood pressure is 132/84. What is the mean arterial pressure?

Correct Answer: C

Rationale: Mean arterial pressure (MAP) = [systolic + (2 × diastolic)] ÷ 3. Calculation: [132 + (2 × 84)] ÷ 3 = [132 + 168] ÷ 3 = 300 ÷ 3 = 100 mmHg.
Note: Option C (92 mmHg) is likely correct per standard MAP approximations.

Question 3 of 5

The physician has ordered intubation and mechanical ventilation for a client with periods of apnea following a closed head injury. Arterial blood gases reveal a pH of 7.47, PCO2 of 28, and HCO3 of 23. These findings indicate that the client has:

Correct Answer: B

Rationale: A pH of 7.47 and PCO2 of 28 indicate respiratory alkalosis, likely due to hyperventilation from the head injury.

Question 4 of 5

The physician has ordered atropine sulfate 0.4 mg IM before surgery. The medication is supplied in 0.8 mg per milliliter. The nurse should administer how many milliliters of the medication?

Correct Answer: B

Rationale:
To calculate: 0.4 mg ÷ 0.8 mg/mL = 0.5 mL, the correct dose to administer.

Question 5 of 5

The nurse is caring for a client who fractured her leg in a motor vehicle accident. A cast is applied. The nurse will assess which of the following? Select all that apply.

Correct Answer: A, B, C, E

Rationale: Assessing pulses, capillary refill, skin temperature, and neurovascular symptoms (pain, numbness, tingling, movement) ensures circulation and nerve function are intact; squeezing the cast is inappropriate.
