Nursing Elites

1. Plantar flexion can be prevented with ________________.

• A. foot soaks
• B. foot boards
• C. toenail care
• D. proper shoes

Correct answer: B

Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.

2. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?

• A. Contain histamine and provide protection during allergic reactions
• B. Are involved in phagocytosis
• C. Provide protection and immunity against foreign substances
• D. Carry hemoglobin and oxygen to body tissues

Correct answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.

3. The clinic nurse teaches a patient with a 42 pack-year history of cigarette smoking about lung disease. Which information will be most important for the nurse to include?

• A. Options for smoking cessation
• B. Reasons for annual sputum cytology testing
• C. Erlotinib (Tarceva) therapy to prevent tumor risk
• D. Computed tomography (CT) screening for lung cancer

Correct answer: A

Rationale: The most critical information for the nurse to provide to a patient with a significant smoking history is options for smoking cessation. Smoking is the primary cause of lung cancer, making smoking cessation essential in reducing the risk of developing the disease. Annual sputum cytology testing is not a standard screening test for lung cancer; instead, CT scanning is being explored for this purpose. Erlotinib therapy is used in lung cancer treatment but not for preventing tumor risk in individuals without cancer. CT screening for lung cancer is still under investigation and is not primarily aimed at prevention but rather early detection in high-risk individuals.

4. One of the complications of complete bed rest and immobility is which of the following?

• A. Plantar flexion
• B. Dorsiflexion
• C. Extension contractures
• D. Adduction contractures

Correct answer: A

Rationale: Plantar flexion, or foot drop, is a common complication of complete bed rest and immobility. This condition occurs due to the weakening of muscles that lift the foot, leading to the foot dragging or being unable to clear the ground during walking. Dorsiflexion refers to moving the foot upwards, which is not a typical complication of immobility. Extension contractures involve the inability to fully extend a joint, while adduction contractures refer to the inability to move a limb away from the body. These types of contractures can also occur with immobility, but they are not specifically associated with foot drop.

5. If a healthcare professional prevents intentional harm from occurring to a patient, which ethical principle is being supported?

• A. Beneficence
• B. Nonmaleficence
• C. Justice
• D. Fidelity

Correct answer: B

Rationale: The correct answer is Nonmaleficence. Nonmaleficence is the ethical principle that emphasizes the obligation to avoid causing harm intentionally. In this scenario, by preventing intentional harm to a patient, the healthcare professional is upholding the principle of nonmaleficence. Beneficence, although important, focuses on doing good and promoting well-being rather than solely preventing harm. Justice relates to fairness and equality in resource distribution, while fidelity involves being faithful and keeping promises, which are not directly applicable to the situation of preventing intentional harm to a patient.
