1. The nurse is teaching a client with cardiac disease about the anatomy and physiology of the heart. Which is the correct pathway of blood flow through the heart?
- A. Right ventricle, left ventricle, right atrium, left atrium
- B. Left ventricle, right ventricle, left atrium, right atrium
- C. Right atrium, right ventricle, left atrium, left ventricle
- D. Right atrium, left atrium, right ventricle, left ventricle
Correct answer: C
Rationale: The correct pathway of blood flow through the heart starts with blood entering the right atrium, moving to the right ventricle, then to the lungs for oxygenation, returning to the left atrium, and finally to the left ventricle before being pumped out to the body. Option A is incorrect as it starts with the ventricles instead of the atria. Option B is incorrect as it has the sequence of ventricles before atria reversed. Option D is incorrect as it has the atria and ventricles mixed up.
2. A child with a diagnosis of celiac disease is admitted to the hospital. What dietary restriction should the nurse teach the parents?
- A. Avoid dairy products
- B. Avoid gluten
- C. Avoid high-fat foods
- D. Avoid foods high in sugar
Correct answer: B
Rationale: The correct answer is to 'Avoid gluten.' Celiac disease is an autoimmune disorder triggered by the consumption of gluten, a protein found in wheat, barley, and rye. When individuals with celiac disease ingest gluten, it causes an immune response that attacks the lining of the small intestine. Therefore, avoiding gluten is crucial in managing celiac disease to prevent symptoms and intestinal damage. Choices A, C, and D are incorrect because they do not address the specific dietary restriction necessary for individuals with celiac disease. While some individuals with celiac disease may also have lactose intolerance (not dairy allergy) or may need to manage fat or sugar intake for other health reasons, the primary dietary focus for celiac disease is the strict avoidance of gluten-containing foods.
3. A client with diabetes mellitus type 2 is prescribed pioglitazone. The nurse should monitor for which potential adverse effect?
- A. Weight gain
- B. Liver toxicity
- C. Kidney stones
- D. Bone fractures
Correct answer: B
Rationale: The correct answer is B, liver toxicity. Pioglitazone is known to cause liver toxicity, so it is essential for the nurse to monitor the client's liver function while on this medication. Monitoring liver function tests can help detect any signs of liver damage early, allowing for timely intervention to prevent serious complications.
4. A nurse is caring for a client who is postoperative and has signs of hemorrhagic shock. When the nurse notifies the surgeon, he directs her to continue to measure the client's vitals every 15 minutes and call him back in 1 hour. From a legal perspective, which of the following actions should the nurse take next?
- A. Notify the nursing manager.
- B. Document the client's condition and communication with the surgeon.
- C. Administer additional fluids as per standard procedure.
- D. Call the surgeon back immediately to ensure timely intervention.
Correct answer: B
Rationale: In this scenario, the nurse should choose option B, which is to document the client's condition and communication with the surgeon. By documenting the client's condition and the communication with the surgeon, the nurse ensures legal protection and maintains continuity of care. This documentation serves as evidence of the actions taken, communication exchanged, and the rationale behind decisions made. Option A, notifying the nursing manager, may not be necessary at this stage unless there are specific institutional protocols requiring it. Administering additional fluids without further clarification may not be appropriate and could worsen the client's condition if not indicated. Calling the surgeon back immediately (option D) may disrupt the agreed-upon plan of action and fail to follow the surgeon's instructions of reassessment after an hour.
5. After mitosis, the genetic code is identical in new cells unless _________ occur through radiation or other environmental influences.
- A. reductions
- B. expulsions
- C. conceptions
- D. mutations
Correct answer: D
Rationale: After mitosis, the genetic code is typically preserved and remains identical in the new cells. However, mutations can occur due to radiation or environmental influences, leading to changes in the DNA sequence and potentially altering the genetic code. Therefore, the correct answer is 'mutations.' Choices A, B, and C are incorrect because reductions, expulsions, and conceptions do not accurately describe the changes in the genetic code that can result from external factors. Mutations are the only option that reflects the alteration in the genetic code caused by external influences, making it the correct choice in this context.
