1. Which of the following is a common side effect of the drug metformin?
- A. Weight loss
- B. Weight gain
- C. Drowsiness
- D. Hypertension
Correct answer: A
Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss as a side effect rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss. Choices B, C, and D are incorrect because weight gain, drowsiness, and hypertension are not typically common side effects of metformin.
2. A client is 4 hours postoperative following abdominal surgery. The client's blood pressure has dropped from 120/80 mm Hg to 90/60 mm Hg. What action should the nurse take first?
- A. Administer an IV fluid bolus.
- B. Check the surgical site for bleeding.
- C. Place the client in a Trendelenburg position.
- D. Notify the healthcare provider.
Correct answer: B
Rationale: Checking the surgical site for bleeding is crucial in this situation as it helps determine if the drop in blood pressure is due to hemorrhage, a potential postoperative complication. Identifying and addressing bleeding promptly is essential to prevent further complications and stabilize the client's condition.
3. Positive feedback mechanisms usually result in
- A. changes returning values away from a set point.
- B. stable conditions around a set point.
- C. unstable conditions.
- D. long-term changes.
Correct answer: unstable conditions.
Rationale: Positive feedback mechanisms usually result in unstable conditions. In a positive feedback loop, the output enhances or amplifies the changes that are occurring, leading to a deviation from the initial set point. Therefore, positive feedback does not bring values back towards the set point (Choice A). Choice B is incorrect because positive feedback does not promote stability around a set point. Choice D is also incorrect as positive feedback mechanisms typically do not lead to long-term changes; instead, they intensify the initial change, causing instability.
4. Which of the following best describes Primary Nursing?
- A. Assigning a nurse to lead a team of registered nurses in the care of a patient from admission to discharge
- B. Assigning a nurse to perform administrative tasks in a healthcare setting
- C. Assigning a nurse to provide medical treatment without supervision
- D. Assigning a nurse to be the main caregiver responsible for coordinating all aspects of care for a group of patients
Correct answer: A
Rationale: Primary Nursing involves assigning a dedicated nurse to lead a team of registered nurses in the care of a patient from admission to discharge. This approach ensures continuity and personalized care. Choices B and C are incorrect as they do not accurately describe Primary Nursing. Choice D is incorrect as it refers to a different care delivery model.
5. Which characteristic in an adolescent female is sometimes associated with the prodromal phase of schizophrenia?
- A. Constantly afraid another student will steal her belongings.
- B. An unusual interest in numbers and specific topics.
- C. Demonstrates no interest in athletics or organized sports.
- D. Appears more comfortable among males.
Correct answer: B
Rationale: During the prodromal phase of schizophrenia, individuals may exhibit subtle changes in behavior or interests. An unusual interest in numbers and specific topics may be a sign of cognitive disturbances that can precede the onset of schizophrenia. While the other choices may also be observed in adolescents, an unusual interest in numbers and specific topics is more specifically linked to potential prodromal symptoms of schizophrenia.
