1. Which of the following terms describes the amount of blood ejected per heartbeat?
- A. Stroke volume
- B. Cardiac output
- C. Ejection fraction
- D. Afterload
Correct answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
2. The nurse has been teaching a patient with type 2 diabetes about managing blood glucose levels and taking glipizide (Glucotrol). Which patient statement indicates a need for additional teaching?
- A. �If I overeat at a meal, I will still take the usual dose of medication.�
- B. �Other medications besides the Glucotrol may affect my blood sugar.�
- C. �When I am ill, I may have to take insulin to control my blood sugar.�
- D. �My diabetes won�t cause complications because I don�t need insulin.�
Correct answer: D
Rationale:
3. Which of the following actions is a means of maintaining medical asepsis to reduce and prevent the spread of microorganisms?
- A. Sterilizing contaminated items
- B. Routinely cleaning the hospital environment
- C. Reapplying a sterile dressing
- D. Applying a sterile gown and gloves
Correct answer: A
Rationale: The correct answer is A: Sterilizing contaminated items. Maintaining medical asepsis involves ensuring that items are free of microorganisms to prevent infections. Sterilizing contaminated items is a crucial step in this process as it eliminates all microorganisms, including spores. Choices B, C, and D do not directly address the process of reducing and preventing the spread of microorganisms. While routinely cleaning the hospital environment is important for cleanliness, it does not guarantee the elimination of all microorganisms. Reapplying a sterile dressing and applying a sterile gown and gloves are specific actions related to personal protective equipment and wound care, not the general maintenance of medical asepsis.
4. The public health nurse is working with a client who desires to move away from eating take-out and fatty foods to maintain a healthier lifestyle. The client mentions eliminating processed foods from her diet most days of the week but still struggles to consistently add fruits and vegetables to her meals. According to the Transtheoretical Model of health behavior change, this client is in which stage:
- A. Pre-contemplation
- B. Contemplation
- C. Preparation
- D. Action
Correct answer: C
Rationale: The client is in the Preparation stage as they are actively taking steps towards behavior change by eliminating processed foods from their diet most days of the week. While they still struggle to consistently add fruits and vegetables, their efforts to make small changes indicate that they are in the Preparation stage, where individuals are getting ready to take action to change their behavior.
5. A client has a new prescription for Clonidine. Which of the following adverse effects should the nurse monitor?
- A. Drowsiness
- B. Dry mouth
- C. Weight gain
- D. Insomnia
Correct answer: B
Rationale: Dry mouth is a common adverse effect of Clonidine. Clonidine can reduce saliva production, leading to dry mouth. To alleviate this symptom, the client should be advised to increase fluid intake or use sugar-free gum or candy. Monitoring for dry mouth is important to prevent complications such as oral health issues. Drowsiness, weight gain, and insomnia are potential side effects of Clonidine but are less common compared to dry mouth. Therefore, the nurse should prioritize monitoring for dry mouth as it's a more prevalent adverse effect associated with this medication.
