Extract:
Question 1 of 5
The nurse is preparing to turn the patient who sustained a spinal cord injury. How should the nurse proceed?
Correct Answer: D
Rationale: Log rolling is the safest way to turn a patient with a spinal cord injury, maintaining spinal alignment and preventing further injury. It requires one person to stabilize the head while others turn the body as a single unit.
Question 2 of 5
A physician prescribes clindamycin 10 mg/kg/day IV in two divided doses for respiratory tract infection. The medication is supplied 150 mg/mL. The patient weighs 88 lbs. How much will the nurse administer per dose? (round to the nearest tenth)
Correct Answer: 1.3 mL
Rationale:
To calculate the dosage of clindamycin, first convert the patient's weight from pounds to kilograms (88 lbs / 2.2 = 40 kg). The prescribed dose is 10 mg/kg/day, so the patient requires 400 mg/day (10 mg/kg * 40 kg). Since the medication is administered in two divided doses, each dose is 200 mg. The medication is supplied at 150 mg/mL, so 200 mg / 150 mg/mL = 1.33 mL, rounded to 1.3 mL per dose.
Question 3 of 5
A patient is ordered 1 mg of Morphine IV push. The medication is supplied in vials 2 mg/1 mL. What should the nurse administer? (round to the nearest tenth)
Correct Answer: 0.5 mL
Rationale:
To administer the correct dose of Morphine, the nurse needs to calculate the volume of medication to deliver 1 mg of Morphine. Since the medication is supplied in a concentration of 2 mg per 1 mL, the nurse would administer half of the volume of the vial to provide the ordered 1 mg dose.
Therefore, the nurse should administer 0.5 mL of Morphine to the patient.
Question 4 of 5
The nurse is caring for a patient with an acute brain injury. Which of the following sets of vital signs would concern the nurse about increasing intracranial pressure (ICP)?
Correct Answer: B
Rationale: This set of vital signs is concerning due to the extremely high blood pressure (220/46) combined with a very low heart rate (30) and low respiratory rate (6), which can indicate an autonomic response to increased ICP, potentially leading to Cushing's triad.
Question 5 of 5
A patient presents to the emergency department with a cervical spinal cord injury immediately after a motor vehicle crash. What should the nurse explain to the family as the reason for the patient being placed on mechanical ventilation? The:
Correct Answer: C
Rationale: The nerves that control lung function may be injured in a cervical spinal cord injury, particularly at higher levels like C3-C5, leading to respiratory muscle paralysis and necessitating mechanical ventilation.
