1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

2. A healthcare provider is caring for a patient who has experienced burns to the right lower extremity. According to the Rule of Nines, which of the following percentages most accurately describes the severity of the injury?

• A. 36%
• B. 27%
• C. 18%
• D. 9%

Correct answer: C

Rationale: According to the Rule of Nines, the right lower extremity accounts for 18% of the total body surface area. The Rule of Nines divides the body into regions, each representing 9% or a multiple of 9%, allowing for a quick estimation of the extent of burns. In this case, the correct answer is 18% as it corresponds to the percentage allocated for each lower extremity. Choices A, B, and D are incorrect as they do not match the standard allocation for the right lower extremity in the Rule of Nines.

3. The client in the Emergency Department, who has suffered an ankle sprain, should be taught to:

• A. use cold applications to the sprain during the first 24-48 hours.
• B. expect disability to decrease within the first 24 hours of injury
• C. expect pain to decrease within 3 hours after injury.
• D. begin progressive passive and active range of motion exercises immediately.

Correct answer: A

Rationale: When a client suffers an ankle sprain, the nurse should teach them to use cold applications to the sprain during the first 24-48 hours. Cold applications are believed to produce vasoconstriction and reduce the development of edema. Expecting disability to decrease within the first 24 hours of injury (choice B) is incorrect as disability and pain are anticipated to increase during the first 2-3 hours after injury. Expecting pain to decrease within 3 hours after injury (choice C) is also incorrect as pain and swelling usually increase initially. Beginning progressive passive and active range of motion exercises immediately (choice D) is not recommended; these exercises are usually started 2-5 days after the injury, according to the physician's recommendation. Treatment for a sprain involves support, rest, and alternating cold and heat applications. X-ray pictures are often necessary to rule out any fractures.

4. Which of the following situations requires nurse intervention?

• A. A certified nursing assistant states, 'The patient in 307 is not wearing gloves while shaving her legs.'
• B. A nursing assistant at the nursing station states, 'The patient in 307 has a respiratory rate of 16.'
• C. A nursing student in the cafeteria states, 'Dr. Jones told the patient in room 307 that she was going to die.'
• D. A certified nursing assistant states, 'Dr. Jones hasn't made rounds this morning.'

Correct answer: C

Rationale: The correct answer is C. Patient confidentiality must be maintained at all times to respect the patient's privacy and dignity. Disclosing sensitive information like a patient's prognosis in a public setting violates confidentiality and can cause distress. The nurse should intervene in this situation and educate the nursing student about the importance of not discussing confidential patient information in public. Choices A, B, and D do not involve breaching patient confidentiality and do not require immediate nurse intervention. Choice A focuses on infection control measures, choice B relates to clinical assessment, and choice D is about the doctor's rounds, which are not urgent matters requiring immediate intervention.

5. At what age will vision be 20/20 in children?

• A. 4 years old
• B. 5 years old
• C. 6 years old
• D. 7 years old

Correct answer: C

Rationale: The correct answer is 6 years old. At this age, children typically have the potential for 20/20 vision. This is considered the standard age for achieving optimal vision clarity. Choices A, B, and D are incorrect as they are not typically associated with the age at which children achieve 20/20 vision.
