1. Which chamber of the heart receives oxygenated blood from the lungs?
- A. Left atrium
- B. Right atrium
- C. Left ventricle
- D. Right ventricle
Correct answer: A
Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.
2. The nurse is caring for the client one (1) day postoperative sigmoid colostomy operation. Which independent nursing intervention should the nurse implement?
- A. Change the infusion rate of the intravenous fluid
- B. Encourage the client to discuss his or her feelings
- C. Administer opioid narcotic medications for pain management
- D. Assist the client out of bed to sit in the chair twice daily
Correct answer: D
Rationale: Assisting the client to sit in a chair is a crucial nursing intervention postoperatively. It helps prevent complications such as thrombosis, pneumonia, and pressure ulcers by promoting circulation and aiding in recovery. Changing the infusion rate of the intravenous fluid would require a physician's order and is not within the nurse's independent scope of practice. Encouraging the client to discuss feelings and administering medications for pain management are important interventions but may not be as immediately necessary as assisting the client in mobilizing early postoperatively.
3. Which of the following types of vitamin or mineral deficiency can cause megaloblastic anemia and is associated with lower extremity paresthesias?
- A. Vitamin B12
- B. Folate
- C. Iron
- D. Vitamin K
Correct answer: A
Rationale: The correct answer is Vitamin B12. Vitamin B12 deficiency can lead to megaloblastic anemia and neurological symptoms, including lower extremity paresthesias. Folate deficiency can also cause megaloblastic anemia but typically does not present with neurological symptoms. Iron deficiency leads to microcytic anemia, not megaloblastic anemia. Vitamin K deficiency is associated with coagulation abnormalities, not megaloblastic anemia.
4. A healthcare professional is preparing to administer vancomycin 1 g by intermittent IV bolus. Available is vancomycin 1 g in 100 mL of dextrose 5% in water (D5W) to infuse over 45 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver?
- A. 22 gtt/min
- B. 24 gtt/min
- C. 20 gtt/min
- D. 18 gtt/min
Correct answer: A
Rationale: To determine the flow rate in drops per minute (gtt/min), you can use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, it would be (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Therefore, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min. Choice B, 24 gtt/min, is incorrect as it results from a miscalculation. Choices C and D, 20 gtt/min and 18 gtt/min respectively, are also incorrect calculations based on the given parameters.
5. Which of the following is not considered a part of body language?
- A. Mannerisms
- B. Speech
- C. Posture
- D. Position
Correct answer: B
Rationale: Body language encompasses non-verbal communication cues such as mannerisms, posture, and position. Speech, although a form of communication, is not typically classified as part of body language. Body language mainly refers to gestures, facial expressions, and body movements, which convey messages non-verbally.
