1. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:
- A. Increases peripheral vascular resistance
- B. Decreases arterial blood flow away from the heart
- C. It's a common resting position when a child is tachycardic
- D. Increases the workload of the heart
Correct answer: A
Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.
2. A home health nurse is preparing for an initial visit with an older adult client who lives alone. Which of the following actions should the nurse take first?
- A. Educate the client about their current medical diagnosis.
- B. Refer the client to a meal delivery program.
- C. Identify environmental hazards in the home.
- D. Arrange transportation for the client to follow-up appointments.
Correct answer: C
Rationale: Identifying environmental hazards in the client's home is the priority during the initial visit with an older adult living alone. This action is crucial to prevent accidents, falls, and ensure the client's safety. While educating the client about their medical diagnosis, referring them to a meal delivery program, and arranging transportation for follow-up appointments are essential, addressing environmental hazards takes precedence as it directly impacts the client's immediate safety and well-being.
3. A nurse is providing care for an older adult client who has been admitted to the hospital with liver cirrhosis. The client has expressed to the nurse his concerns that the details of his condition and treatment remain confidential, and that written documentation not 'get out there.' How can the nurse best respond to the client's concerns?
- A. Anything that is discussed between us is confidential and will not be shared with anyone else.
- B. The Health Insurance Portability and Accountability Act ensures that your medical records will not leave this hospital.
- C. Provided you signed a directive on admission, your records will not be made public.
- D. The law protects your right to confidentiality and protects your health information from being released into unintended hands.
Correct answer: D
Rationale: The correct answer is D. The Health Insurance Portability and Accountability Act (HIPAA) is a federal law that protects individuals' right to confidentiality and safeguards health information from being accessed by unauthorized individuals. Assuring the client that the law protects their right to confidentiality and prevents their health information from being released into unintended hands is the best response. Choice A is too broad and may not cover all aspects of confidentiality. Choice B only mentions medical records staying within the hospital, which does not address the client's concern about written documentation. Choice C incorrectly implies that a signed directive is needed for confidentiality, which is not true under HIPAA regulations.
4. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should monitor which laboratory test to determine the effectiveness of the therapy?
- A. Prothrombin time (PT) and international normalized ratio (INR)
- B. Activated partial thromboplastin time (aPTT)
- C. Complete blood count (CBC)
- D. Fibrinogen level
Correct answer: A
Rationale: To monitor the effectiveness of warfarin therapy in a client with atrial fibrillation, the nurse should assess the Prothrombin time (PT) and international normalized ratio (INR) levels. These tests help determine the clotting ability of the blood and ensure that the client's anticoagulation levels are within the therapeutic range, reducing the risk of bleeding or clotting complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy. Complete blood count (CBC) (Choice C) provides information about the cellular components of blood but does not directly assess the effectiveness of warfarin therapy. Fibrinogen level (Choice D) is not typically used to monitor warfarin therapy; it reflects the level of fibrinogen in the blood, which is involved in the clotting process.
5. Which of the following vaccines is recommended to be given at birth?
- A. BCG
- B. Hepatitis B
- C. OPV
- D. Measles
Correct answer: A
Rationale: The BCG vaccine is recommended to be given at birth to protect against tuberculosis. It is often administered soon after birth to provide early protection against the disease, especially in areas where tuberculosis is prevalent.
