1. The parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) ask, 'How can our son have this disease? We are wondering if we should have any more children.' What information should the nurse provide these parents?
- A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family.
- B. The male infant had a viral infection that went unnoticed and untreated, leading to muscle damage.
- C. The lack of the protein dystrophin in the mother can impact the XXX muscle groups of males.
- D. Spinal cord damage due to birth trauma during a breech vaginal birth weakens the muscles.
Correct answer: A
Rationale: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder, meaning the gene mutation causing DMD is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if the X chromosome they inherit from their mother carries the mutated gene, they will develop DMD. Females have two X chromosomes, so they are carriers of the gene but are usually not affected by the disease. Therefore, the nurse should explain to the parents that DMD is an inherited X-linked recessive disorder that primarily affects male children in the family.
2. A 10-year-old girl who has had type 1 diabetes mellitus (DM) for the past two years tells the nurse that she would like to use a pump instead of insulin injections to manage her diabetes. Which assessment of the girl is most important for the nurse to obtain?
- A. Understanding of the quality control process used to troubleshoot the pump
- B. Interpretation of fingerstick glucose levels that influence diet selections
- C. Knowledge of her glycosylated hemoglobin A1c levels for the past year
- D. Ability to perform the pump for basal insulin with mealtime boluses
Correct answer: A
Rationale: In a patient transitioning to an insulin pump, understanding the quality control process to troubleshoot the pump is crucial for ensuring proper and safe management of diabetes. This knowledge enables the individual to identify and address any issues that may arise with the pump, helping maintain optimal glycemic control and prevent complications. Choices B, C, and D, although important in diabetes management, are not as critical as ensuring the correct understanding of troubleshooting the pump, which directly impacts the girl's ability to effectively use the pump for insulin delivery.
3. The Punnett square shows that one parent carries the recessive gene for a cleft chin (c) while the other parent does not. What percentage of the parents' offspring is predicted to have a cleft chin?
- A. 25%
- B. 50%
- C. 0%
- D. 75%
Correct answer: C
Rationale: The correct answer is 0%. If one parent carries the recessive gene for a cleft chin while the other parent does not, none of the offspring will express the recessive phenotype. This is because in order for a child to have a cleft chin, they would need to inherit the recessive gene from both parents. Therefore, although the offspring could be carriers of the gene, none are predicted to have a cleft chin. Choices A, B, and D are incorrect because the presence of the recessive gene in one parent and its absence in the other would not result in any offspring showing the cleft chin trait.
4. A client with end-stage pulmonary disease requests 'no heroic measures' if she stops breathing. What should the nurse do next?
- A. Document the client's request in the medical record.
- B. Ask the client to discuss a DNR order with her healthcare provider.
- C. Consult the ethics committee for guidance.
- D. Discharge the client with no further discussion.
Correct answer: B
Rationale: The correct next step for the nurse is to ask the client to discuss a 'do not resuscitate' (DNR) order with her healthcare provider. While the client's wishes should be respected, it is essential to ensure proper documentation and legal protection by involving the healthcare provider in this decision-making process. Documenting the request in the medical record (Choice A) is important but should follow the discussion with the healthcare provider. Consulting the ethics committee (Choice C) may not be necessary at this stage and could delay the necessary actions. Discharging the client (Choice D) without further discussion is not appropriate and disregards the importance of addressing the client's wishes in a respectful and professional manner.
5. The nurse is preparing to administer a blood transfusion to a client. Which action is most important for the nurse to take before starting the transfusion?
- A. Administer pre-transfusion medication
- B. Ensure the client has an adequate fluid intake
- C. Monitor the client's vital signs
- D. Verify the blood type with another nurse
Correct answer: D
Rationale: Verifying the blood type with another nurse is critical before starting a blood transfusion to prevent a potentially life-threatening transfusion reaction. This step ensures that the client receives the correct blood product. Administering pre-transfusion medication, ensuring adequate fluid intake, and monitoring vital signs are important steps during the transfusion process, but verifying the blood type is the most crucial step to ensure patient safety.
