Nursing Elites

1. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

2. A healthcare professional is caring for a client who is newly diagnosed with pancreatic cancer and has questions about the disease. To research, the healthcare professional should identify that which of the following electronic databases has the most comprehensive collection of nursing articles?

• A. MEDLINE
• B. CINAHL
• C. ProQuest
• D. Health Source

Correct answer: B

Rationale: CINAHL (Cumulative Index to Nursing and Allied Health Literature) is a comprehensive database that specializes in nursing and allied health literature. It is a valuable resource for healthcare professionals seeking nursing-related articles, making it the most appropriate option for the nurse caring for a client with questions about pancreatic cancer.

3. The four main concepts common to nursing that appear in each of the current conceptual models are:

• A. Person, nursing, environment, medicine
• B. Person, health, nursing, support systems
• C. Person, health, psychology, nursing
• D. Person, environment, health, nursing

Correct answer: D

Rationale: The four main concepts common to nursing that appear in each of the current conceptual models are person, environment, health, and nursing. These concepts form the foundational principles that guide nursing practice and theory.

4. 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.

5. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.
