1. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

2. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

3. A client experiencing acute dyspnea and diaphoresis reports anxiety and difficulty breathing. Vital signs include HR 117/min, respirations 38/min, temperature 38.4 C (101.2 F), and blood pressure 100/54 mm Hg. What should the nurse prioritize?

• A. Notify the provider.
• B. Administer heparin via IV infusion.
• C. Administer oxygen therapy.
• D. Obtain a spiral CT scan.

Correct answer: C

Rationale: In a client with acute dyspnea, diaphoresis, tachycardia, tachypnea, fever, and hypotension, the priority is to ensure adequate oxygenation. Administering oxygen therapy helps improve oxygenation levels and stabilize the client's condition. This intervention takes precedence over notifying the provider, administering heparin, or obtaining a CT scan, as oxygen therapy addresses the client's immediate need for respiratory support.

4. A client had oral surgery following a motor vehicle accident. The nurse assessing the client finds the skin flushed and warm. Which of the following would be the best method to take the client’s body temperature?

• A. Oral
• B. Axillary
• C. Arterial line
• D. Rectal

Correct answer: D

Rationale: In cases where the oral route is contraindicated due to oral surgery or altered consciousness, the rectal method is preferred for the most accurate body temperature reading. This method is particularly useful when the skin is flushed and warm, as it provides a reliable reflection of core body temperature despite external factors affecting the skin temperature. Axillary temperature may not be as accurate as rectal temperature due to variations caused by environmental factors and technique. Arterial line temperature monitoring is invasive and not typically used for routine temperature assessment.

5. A patient requires augmentation of labor. Which of the following conditions should the nurse recognize as a contraindication to the use of oxytocin?

• A. Diabetes mellitus
• B. Shoulder presentation
• C. Postterm with oligohydramnios
• D. Chorioamnionitis

Correct answer: C

Rationale: Postterm pregnancy with oligohydramnios is a contraindication for the use of oxytocin due to the increased risk of uterine hyperstimulation and fetal distress. Oxytocin can further stress the fetus in this scenario, potentially leading to adverse outcomes. Therefore, it is crucial for the nurse to recognize this contraindication to ensure the safety of both the mother and the baby during labor.
