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. How many drops are equivalent to 1 tsp?

• A. 15
• B. 60
• C. 10
• D. 30

Correct answer: B

Rationale: 1 teaspoon (tsp) is equivalent to approximately 60 drops. Drops and teaspoons vary in volume and size, affecting the conversion ratio. Choice A (15 drops) is incorrect as it's a common misconception. Choice C (10 drops) and Choice D (30 drops) do not align with the standard conversion of 1 tsp to 60 drops.

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 is to receive thrombolytic therapy. Which of the following factors should be recognized as a contraindication to the therapy?

• A. Hip arthroplasty 2 weeks ago
• B. Elevated sedimentation rate
• C. Incident of exercise-induced asthma 1 week ago
• D. Elevated platelet count

Correct answer: A

Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.

5. When applying Nagele's rule, a healthcare professional is estimating a client's expected date of delivery based on their last menstrual period, which began on April 12th. What date should the healthcare professional determine to be the client's expected delivery date? (Use mmdd format.)

• A. 119
• B. 121
• C. 115
• D. 122

Correct answer: A

Rationale: To calculate the expected delivery date using Nagele's rule, begin by subtracting 3 months from the first day of the last menstrual period (April 12th), which results in January 12th. Then, add 7 days. Therefore, the expected delivery date would be January 19th (0119). This calculation method helps healthcare professionals estimate the client's due date.
