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. One week ago, a client was involved in a motor vehicle crash (MVC) and was brought to the Emergency Department (ED). In the emergency department, the client received two stitches to the forehead and was sent home. Today, the client's spouse notes that the client 'acts like he is drunk' and cannot control his right foot and arm. The nurse will suspect?
- A. Meningitis
- B. Absence seizure
- C. Subdural hematoma
- D. Meniere's disease
Correct answer: C
Rationale: Yes! The nurse will suspect a subdural hematoma. In this case, the client's presentation of acting intoxicated and experiencing loss of motor control in the right foot and arm is indicative of an acute subdural hematoma. This condition can occur after a head injury with a slow venous bleed, where symptoms may not show until compensation mechanisms are overwhelmed. Meningitis (choice A) usually presents with fever, headache, and neck stiffness. Absence seizure (choice B) is characterized by brief periods of unconsciousness without convulsions. Meniere's disease (choice D) manifests with symptoms like vertigo, hearing loss, and tinnitus, which do not match the client's current symptoms.
3. A healthcare professional is assessing a patient in the rehab unit during shift change. The patient has sustained a TBI 3 weeks ago. Which of the following is the most distinguishing characteristic of a neurological disturbance?
- A. LOC (level of consciousness)
- B. Short-term memory
- C. Babinski sign
- D. Clonus sign
Correct answer: A
Rationale: Level of consciousness (LOC) is the most crucial indicator of impaired neurological function. Changes in LOC can signify various neurological conditions, including traumatic brain injury. Short-term memory, while important, is not the most distinguishing characteristic of neurological disturbances. Babinski and Clonus signs are specific neurological tests that can provide information about upper motor neuron lesions but are not as generalizable as changes in LOC for assessing overall neurological status.
4. A nurse is instructing a patient on the order of sensations with the application of an ice water bath for a swollen right ankle. Which of the following is the correct order of sensations experienced with an ice water bath?
- A. cold, burning, aching, and numbness
- B. burning, aching, cold, and numbness
- C. aching, cold, burning, and numbness
- D. cold, aching, burning, and numbness
Correct answer: A
Rationale: The correct order of sensations experienced with an ice water bath is cold, burning, aching, and numbness, as stated by the acronym CBAN (cold, burn, ache, numbness). Option A is the correct sequence. Choice B is incorrect as it starts with burning, which typically follows the cold sensation. Choice C is incorrect as aching is usually felt after the burning sensation. Choice D is incorrect as aching usually occurs after the burning sensation.
5. Which is an example of a sentinel event?
- A. The terminally ill client is referred to hospice and dies 3 months later.
- B. A client receives an unordered mammogram which reveals a small cyst.
- C. A client with a laceration to the knee requiring 4 sutures falls when getting up unassisted after being instructed to remain in bed.
- D. A client scheduled for knee replacement surgery had an above-the-knee amputation performed.
Correct answer: D
Rationale: Yes! A sentinel event is an unexpected occurrence causing death or serious injury. In this case, a client who was scheduled for knee replacement surgery but had an above-the-knee amputation performed instead represents a sentinel event as it resulted in serious harm that was not intended. The other choices do not meet the criteria for a sentinel event. Choice A describes a natural progression for a terminally ill client, choice B shows an incidental finding from a test, and choice C involves a preventable fall leading to an injury but not a sentinel event.
