1. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

2. A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:

• A. Expose the cast to air and turn the child frequently.
• B. Use a heat lamp to reduce the drying time.
• C. Handle the cast with the abductor bar.
• D. Turn the child as little as possible.

Correct answer: A

Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.

3. When assessing the respiratory system of an older patient, which finding indicates that the nurse should take immediate action?

• A. Weak cough effort
• B. Barrel-shaped chest
• C. Dry mucous membranes
• D. Bilateral crackles at lung bases

Correct answer: D

Rationale: Bilateral crackles at lung bases indicate a potential acute issue like heart failure. Immediate action is necessary in this situation. The nurse should conduct further assessments such as oxygen saturation and inform the healthcare provider promptly. A barrel-shaped chest and hyperresonance to percussion are typical signs of aging and do not require immediate action. A weak cough effort is common in older patients due to age-related changes, and dry mucous membranes are also expected in older individuals. While these findings may warrant further evaluation, they do not demand immediate action like bilateral crackles at lung bases.

4. Which of the following is the most common type of malignant brain tumor in the United States?

• A. Meningioma
• B. Glioblastoma multiforme
• C. Acoustic neuroma
• D. Pituitary adenoma

Correct answer: B

Rationale: Glioblastoma multiforme is the most common malignant brain tumor in the United States, accounting for a significant portion of cases. It is known for its aggressive nature and poor prognosis. Surgical resection, followed by radiation and chemotherapy, is the standard treatment approach for glioblastoma multiforme. Meningioma, acoustic neuroma, and pituitary adenoma are also types of brain tumors but are not as common as glioblastoma multiforme in the United States.

5. Mr. V is receiving treatment for a spinal cord injury after falling off of his deck at home. He has undergone spinal surgery and has been placed in a halo traction device. Which of the following nursing interventions is most appropriate for a client with a spinal cord injury?

• A. Turn the client and use incentive spirometry each shift
• B. Administer stool softeners as ordered
• C. Turn the head slowly to avoid further damage to the spine
• D. Change NPO status

Correct answer: B

Rationale: In a client with a spinal cord injury, administering stool softeners as ordered is a crucial nursing intervention. Patients with spinal cord injuries are at higher risk of constipation due to decreased mobility. Stool softeners help prevent constipation and potential fecal impaction. Turning the client and using incentive spirometry each shift can be beneficial for respiratory function but is not the most vital intervention in this scenario. Turning the head slowly to avoid further damage to the spine is important but is not directly related to preventing constipation. Changing NPO status is not relevant to preventing constipation or managing a spinal cord injury.
