Nursing Elites

1. What is the primary function of hemoglobin in red blood cells?

• A. Oxygen transport
• B. Immunity
• C. Blood clotting
• D. Carbon dioxide transport

Correct answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.

2. All of the following are posture and body alignment problems EXCEPT:

• A. Kyphosis
• B. Scoliosis
• C. Thrombosis
• D. Lumbar lordosis

Correct answer: C

Rationale: Thrombosis is a condition involving blood clots and is not related to posture or body alignment, unlike kyphosis, scoliosis, and lumbar lordosis, which are spinal alignment issues. Kyphosis refers to excessive outward curvature of the spine, scoliosis is characterized by a sideways curvature of the spine, and lumbar lordosis involves an exaggerated inward curve in the lower back. Thrombosis, on the other hand, is a condition where blood clots form in the blood vessels, not a posture or body alignment problem.

3. Which of the following is NOT a second-line agent used for the treatment of Tuberculosis?

• A. Amikacin
• B. Moxifloxacin
• C. Rifabutin
• D. Cycloserine

Correct answer: C

Rationale: The correct answer is C, Rifabutin. Rifabutin is actually a first-line drug used in the treatment of tuberculosis. Choices A, B, and D (Amikacin, Moxifloxacin, and Cycloserine) are considered second-line agents for tuberculosis treatment. These drugs are used when the first-line medications are either ineffective or cannot be tolerated by the patient.

4. The nurse is preparing to provide wound care for a client. Which step should be done first?

• A. Don procedural gloves
• B. Remove the dressing
• C. Apply prescribed medications to the wound
• D. Don a pair of sterile gloves

Correct answer: A

Rationale: The correct answer is to don procedural gloves first. Donning procedural gloves is essential to protect the nurse from contaminants while removing the old dressing. This step helps maintain aseptic technique and prevents the transfer of microorganisms. Removing the dressing (choice B) should follow after wearing gloves to prevent the spread of pathogens. Applying prescribed medications (choice C) should be done after the wound is cleaned and dressed. Donning a pair of sterile gloves (choice D) is not necessary for initial wound care; procedural gloves are sufficient for standard wound care.

5. Before administering a scheduled dose of insulin to a 10-year-old child who is learning diabetic self-care, which information is most important for the PN to ask the child?

• A. How much exercise did the child have today?
• B. Did the child perform a finger stick?
• C. When did the child last urinate?
• D. Has the child eaten recently?

Correct answer: B

Rationale: The correct answer is B: 'Did the child perform a finger stick?' Before administering insulin, it is crucial to check the child's blood glucose level to prevent hypoglycemia. Performing a finger stick blood glucose test provides essential information on the current blood sugar level. Choice A ('How much exercise did the child have today?') is not as critical as monitoring blood glucose levels directly. Choice C ('When did the child last urinate?') is not directly related to the immediate need for insulin administration. Choice D ('Has the child eaten recently?') is important but not as crucial as knowing the current blood glucose level.
