1. What is the primary function of hemoglobin in red blood cells?

• A. Oxygen transport
• B. Immunity
• C. Blood clotting
• D. Carbon dioxide transport

Correct answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.

2. Which nursing intervention is most appropriate for managing delirium in an elderly patient?

• A. Keeping the room brightly lit
• B. Administering sedatives as needed
• C. Encouraging family presence
• D. Restricting fluids

Correct answer: C

Rationale: Encouraging family presence is the most appropriate intervention for managing delirium in elderly patients. This intervention provides orientation, reassurance, and comfort, which can help reduce confusion and anxiety, thus aiding in managing delirium. Keeping the room brightly lit (Choice A) may worsen delirium as it can disrupt the patient's sleep-wake cycle. Administering sedatives (Choice B) should be avoided unless absolutely necessary due to the risk of worsening delirium. Restricting fluids (Choice D) is not a recommended intervention for managing delirium, as hydration is important for overall patient well-being.

3. After spinal fusion surgery, a client reports numbness and tingling in the legs. What should the nurse do first?

• A. Assess the client’s neurovascular status in the lower extremities.
• B. Reposition the client to relieve pressure on the spine.
• C. Administer prescribed pain medication.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: After spinal fusion surgery, numbness and tingling in the legs may indicate nerve compression or damage. The priority action for the nurse is to assess the client’s neurovascular status in the lower extremities. This assessment will help determine the cause and severity of the symptoms, guiding further interventions. Repositioning the client may be necessary for comfort, but assessing neurovascular status is the initial step. Administering pain medication should only follow the assessment to address any discomfort. Notifying the healthcare provider immediately is not the first action unless there are emergent signs requiring urgent intervention.

4. The PN is reviewing care instructions with a client who has diabetic retinopathy and is experiencing glare around lights. What should the PN reinforce with the client?

• A. Cover eyes with moist, cool compresses to reduce glare
• B. Make adjustments to personal schedule to avoid driving at night
• C. Exert pressure on the inner canthus when tearing occurs
• D. Apply an eye shield at bedtime after instilling eye drops

Correct answer: B

Rationale: The correct answer is B. Avoiding driving at night is recommended for clients experiencing glare around lights due to diabetic retinopathy. This can help reduce the risk of accidents and visual discomfort. Making adjustments to the personal schedule to avoid nighttime driving is a practical approach to manage the glare. Choices A, C, and D are incorrect because covering eyes with compresses, exerting pressure on the inner canthus, or applying an eye shield are not effective strategies for managing glare associated with diabetic retinopathy.

5. What is the primary cause of diabetic ketoacidosis (DKA)?

• A. Insulin deficiency
• B. Overhydration
• C. Excess carbohydrate intake
• D. Excess insulin

Correct answer: A

Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.
