Nursing Elites

1. 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.

2. A patient with peripheral vascular disease is receiving discharge instructions. Which of the following information should be included?

• A. Walk barefoot whenever possible.
• B. Use a heating pad to keep feet warm.
• C. Avoid crossing the legs.
• D. Use antibacterial ointment to treat skin lesions prone to infection.

Correct answer: C

Rationale: Patients with peripheral vascular disease should be advised to avoid crossing their legs as this can impede blood flow. Peripheral vascular disease, also known as arteriosclerosis obliterans, is primarily caused by atherosclerosis. Atherosclerosis results in the gradual progression of arterial occlusion due to the formation of atheromas. Crossed legs can further restrict blood flow, exacerbating the condition. Walking barefoot should be discouraged to prevent potential injuries to the feet. Using a heating pad can lead to burns and should be avoided to prevent thermal injuries. While using antibacterial ointment for skin lesions may be beneficial, it is not the priority instruction for patients with peripheral vascular disease.

3. A patient with bipolar disorder asks the nurse, "Why did I get this illness? I don't want to be sick."? The nurse would best respond with:

• A. People who develop mental illnesses often had a very traumatic childhood experience.
• B. There is some evidence that contracting a virus during childhood can lead to mental disorders.
• C. Sometimes people with mental illness have an overactive immune system.
• D. We don't fully understand the cause, but mental illnesses do seem to run in the family.

Correct answer: D

Rationale: The correct response is, 'We don't fully understand the cause, but mental illnesses do seem to run in the family.' Current research suggests that while genetics play a role in the development of mental illnesses like bipolar disorder, it is not the sole factor. Environmental influences, life experiences, and other non-genetic factors also contribute significantly to the manifestation of mental disorders. Choices A, B, and C provide incorrect information that is not supported by current research. Traumatic childhood experiences, contracting a virus during childhood, and an overactive immune system are not established causes of bipolar disorder or mental illnesses in general.

4. All of the following are essential components of supervision EXCEPT:

• A. All tasks to be delegated or supervised are within the nurse's scope of practice
• B. The necessary tasks require repeated assessments
• C. The nurse has adequate time to develop staff assignments
• D. Policies have been developed that govern nursing practice

Correct answer: B

Rationale: Supervision in nursing requires key components to ensure effective management. Tasks to be delegated or supervised must align with the nurse's scope of practice to maintain safety and quality care. Adequate time for staff assignment development is essential for efficient workflow. Policies governing nursing practice provide a framework for safe and standardized care. However, the statement 'The necessary tasks require repeated assessments' is not an essential component of supervision. Tasks should be clear, achievable, and not necessitate repeated assessments, as this would impede delegation and efficient completion. Repeated assessments may indicate unclear task delegation or inadequate initial assessment, which should be avoided in effective supervision.

5. While caring for a client who has just come from surgery and is in the recovery room with an endotracheal tube in place, the nurse deflates the cuff on the tube and removes it. The client sits up in bed, grasps his throat, and begins to make wheezing sounds. Which of the following conditions is the most likely cause of this situation?

• A. The client is choking on part of the tube
• B. The client has anxiety
• C. The client is having a laryngospasm
• D. The client is having a normal response from anesthesia

Correct answer: D

Rationale: After surgery, some clients may experience a laryngospasm during emergence from anesthesia. A laryngospasm can lead to the closure of the laryngeal opening due to spasm of the vocal cords. In this scenario, the client's symptoms of wheezing and throat grasping are indicative of a laryngospasm rather than choking on the tube, anxiety, or a normal response from anesthesia. The nurse should act promptly to open the airway to aid breathing and consider administering muscle relaxants as necessary.
