Mr. Campbell has just received a permanent pacemaker and is returned to your unit. Which teaching needs assumes the highest priority at this time?

Correct Answer: D

Rationale: The correct answer is D) The symptoms of pacemaker malfunction. This teaching need assumes the highest priority because recognizing and understanding the symptoms of pacemaker malfunction is crucial for the patient's safety and well-being. Knowing the signs of malfunction such as dizziness, palpitations, chest pain, or fainting allows the patient to seek immediate medical attention, potentially preventing serious complications or even death. Option A) How to take his pulse daily is important but not as critical as recognizing symptoms of pacemaker malfunction. Monitoring pulse is a routine activity, whereas identifying malfunction symptoms is a matter of urgent concern. Option B) The importance of wearing a medical-alert bracelet is also essential but does not take precedence over knowing the symptoms of malfunction. While the bracelet provides important information in case of emergencies, knowing when to seek help due to malfunction is more pressing. Option C) The positive aspects of life with a pacemaker is a valuable topic for overall patient education but is not as urgent as understanding the signs of malfunction. Patient education on lifestyle adjustments and coping mechanisms can be addressed at a later time once the immediate safety concerns are covered. In an educational context, prioritizing teaching needs based on urgency and potential impact on patient outcomes is crucial in healthcare settings. By focusing on the most critical information first, educators can ensure that patients are equipped with the knowledge needed to manage their health effectively and respond appropriately to emergencies.

Correct Answer: D

Rationale: The correct answer is D) vitamin B12 and disturbed nervous system functioning. Understanding the relationship between vitamin B12 and disturbed nervous system functioning is crucial for Mrs. Young as vitamin B12 plays a key role in maintaining the health of nerve cells and producing myelin, a substance that protects nerve fibers. Deficiency in vitamin B12 can lead to neurological symptoms such as numbness, tingling, and memory problems. Option A) chemotherapy and alopecia is incorrect as chemotherapy is commonly associated with alopecia (hair loss), not vitamin B12. Option B) drinking a quart of milk daily and preventing iron deficiency is incorrect as milk is not a primary source of iron, and iron deficiency is not directly related to milk consumption. Option C) nitroglycerin and the relief of angina is incorrect as nitroglycerin is a medication used to relieve chest pain (angina) by dilating blood vessels, not related to vitamin B12. Educationally, understanding the relationship between specific nutrients like vitamin B12 and their impact on bodily functions is essential for patients to make informed decisions about their health, especially when managing conditions that are influenced by nutritional factors. This knowledge empowers individuals to take proactive steps in maintaining their well-being and seeking appropriate interventions when necessary.

Correct Answer: A

Rationale: In hematology, monitoring patients receiving blood transfusions is crucial to prevent potential complications. The correct answer is A) acute blood loss. Patients with acute blood loss are at risk of hypovolemic shock, which can lead to serious consequences such as organ failure and death. By observing the rate of flow and the patient's response to the transfusion, the nurse can assess if the therapy is effectively addressing the patient's condition. Option B) heart conditions is incorrect because although patients with heart conditions may require blood transfusions, the immediate concern for close monitoring lies with patients experiencing acute blood loss. Option C) iron deficiency anemia is incorrect as these patients usually receive iron supplementation or iron-rich foods, not necessarily blood transfusions. Option D) folic acid deficiency is incorrect because folic acid deficiency is typically treated with oral folic acid supplementation, not blood transfusions. Educationally, understanding the rationale behind the need for close monitoring of blood transfusions in specific patient populations is essential for nursing practice. Nurses must be able to differentiate which patients are at high risk for complications and require vigilant observation to ensure safe and effective care delivery. This knowledge is critical for providing quality patient care and preventing adverse outcomes.

Correct Answer: A

Rationale: Rationale: The correct answer is A) intramuscular injections. Clients with hemophilia, a genetic disorder that impairs blood clotting, should avoid intramuscular injections to prevent excessive bleeding. Hemophiliacs have deficiencies in clotting factors VIII (hemophilia A) or IX (hemophilia B), making them prone to prolonged bleeding episodes even from minor injuries. Administering medications intramuscularly can lead to significant bleeding, hematoma formation, and potential complications. Option B) fresh whole blood administration is incorrect because receiving fresh whole blood can actually be beneficial for hemophiliac patients in cases of severe bleeding episodes, providing them with essential clotting factors. Option C) dental extractions can be managed in clients with hemophilia with appropriate prophylactic clotting factor replacement therapy and close monitoring by medical professionals. While precautions are needed, dental extractions are not categorically contraindicated. Option D) contact sports should be avoided by clients with hemophilia due to the increased risk of traumatic injury and bleeding episodes. Engaging in contact sports can lead to serious bleeding complications, joint damage, and other health risks in individuals with hemophilia. Educational Context: Educating clients with hemophilia about lifestyle modifications and potential risks is crucial in managing their condition effectively. Nurses and healthcare providers play a key role in providing information on safe practices to prevent bleeding episodes and improve quality of life for individuals with hemophilia. By understanding and following these recommendations, clients can reduce the likelihood of complications and maintain their health and well-being.

Correct Answer: D

Rationale: Leukemia is characterized by the uncontrolled proliferation of white blood cells, making option D the correct answer. In leukemia, there is a disruption in the normal production of white blood cells, leading to the overproduction of abnormal white blood cells. These abnormal cells do not function properly and can overcrowd the bone marrow, impairing the production of normal blood cells. Option A, destruction of the marrow of long bones, is incorrect because while leukemia does affect the bone marrow, it does not necessarily lead to the destruction of long bones. Option B, excessive circulating red blood cells, is incorrect because leukemia primarily affects white blood cells, not red blood cells. Option C, significant reduction in the white cell count, is also incorrect because leukemia actually results in an increase in the number of white blood cells, albeit abnormal ones. In an educational context, understanding the characteristics of leukemia is crucial for healthcare professionals, especially those working in hematology or oncology. Recognizing the hallmark features of leukemia, such as the uncontrolled proliferation of white blood cells, can aid in early detection, diagnosis, and management of the disease. This knowledge is also essential for nurses and other healthcare providers caring for patients with leukemia, as it influences treatment strategies and patient outcomes.
