Nursing Elites

1. Which of the following conditions may cause an increased respiratory rate?

• A. Stooped posture
• B. Narcotic analgesics
• C. Injury to the brain stem
• D. Anemia

Correct answer: D

Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen. Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.

2. Research participants are involved in a trial that incidentally separates them into two groups. One group receives an intervention, while the other group does not. Both groups are compared for outcomes. What type of research method is this?

• A. Experimental design
• B. Double-blind experiment
• C. Randomized controlled trial
• D. Repeated measures design

Correct answer: C

Rationale: A randomized controlled trial is a research method in which participants are randomly assigned to either a treatment or control group. This design helps eliminate bias and allows for the comparison of outcomes between the two groups. In this scenario, where participants are separated into intervention and non-intervention groups for comparison, it aligns with the characteristics of a randomized controlled trial. The key feature distinguishing it from the other options is the random assignment of participants to groups, ensuring that both groups are comparable at the start of the study. Double-blind experiments involve blinding both participants and researchers to treatment allocation, which is not explicitly mentioned in the scenario. Experimental design refers to a broader category that includes various types of research designs beyond just randomized controlled trials. Repeated measures design involves collecting multiple observations from the same participants over time, which is not the case described in the scenario.

3. 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.

4. A client is preparing to undergo a cystoscopy for stones. Which of the following statements indicates that the client understands the procedure?

• A. I better drink a lot of fluid now because I won't be able to after the test.
• B. I will probably see a little blood when I urinate.
• C. I will be able to go home after 3 days in the hospital.
• D. I won't need any pain medicine; this probably will not hurt.

Correct answer: B

Rationale: The correct answer is, 'I will probably see a little blood when I urinate.' During a cystoscopy, a scope is inserted into the client's bladder to inspect structures or remove objects like stones. This procedure is usually performed under local or general anesthesia. It is common for clients to experience a small amount of blood in their urine (hematuria) or have pink-colored urine after the procedure. The other choices are incorrect because drinking a lot of fluid before the test, staying in the hospital for 3 days, and assuming no pain will be experienced are not accurate statements related to a cystoscopy procedure.

5. 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.
