LPN exams cardiovascular practice questions set 11

Correct answer:

The correct answer is D: Vomiting center. Ondansetron and aprepitant are antiemetic medications that work by inhibiting signaling in the vomiting center of the brain. The vomiting center is located in the medulla oblongata in the brainstem, which plays a crucial role in triggering the reflexes that lead to nausea and vomiting. By blocking signals in the vomiting center, these medications effectively prevent and control nausea and vomiting. Incorrect choices: A: The vestibular system is responsible for balance and spatial orientation, not for controlling nausea and vomiting. B: The cerebral cortex is involved in higher brain functions such as thinking and decision-making, not in regulating nausea and vomiting. C: The hypothalamus regulates various physiological processes like temperature regulation and hormone release, but it is not directly involved in controlling nausea and vomiting.

Correct answer:

The correct answer is A because women are at higher risk for tardive dyskinesia while taking conventional antipsychotic medications. This fact is crucial for the nurse's assessment because tardive dyskinesia is a serious side effect characterized by involuntary movements and can be irreversible. Understanding this risk allows the nurse to closely monitor the patient for symptoms and intervene promptly if needed. Choice B is incorrect because there is no evidence to suggest that women experience more severe side effects than men while taking atypical antidepressants. Choice C is incorrect as there is no generalization that women are more susceptible to developing a dependence on most psychiatric medications compared to men. Choice D is incorrect because there is no established evidence that women are less susceptible to developing common side effects of antipsychotic medications than men.

Correct answer:

Rationale: Choice C is correct because assessing the patient's specific needs for education and support is crucial in addressing psychosocial needs. By understanding the patient's knowledge gaps and support requirements, the nurse can provide tailored information and resources to help the patient cope effectively. This empowers the patient to make informed decisions and feel supported throughout the treatment process. Incorrect Choices: A: Assessing the patient's previous experience with the health care system may provide some insight but does not directly address the current psychosocial needs. B: Reassuring the patient about treatment success is important but may not adequately address the patient's immediate distress and uncertainty. D: Identifying the patient's plan of medical care is important but focuses more on the medical aspect rather than psychosocial support and education.

Correct answer:

The correct answer is B: Risk for Infection. During induction therapy for acute myeloid leukemia, the patient's immune system is compromised, making them highly susceptible to infections. Therefore, the highest priority nursing diagnosis should be addressing and preventing infections. This includes monitoring for signs of infection, implementing proper infection control measures, educating the patient and family on infection prevention, and administering prophylactic antibiotics as needed. Choice A (Activity Intolerance) may be a concern due to the patient's underlying condition and treatment, but preventing infections takes precedence as it can lead to life-threatening complications. Choice C (Acute Confusion) and Choice D (Risk for Spiritual Distress) are important considerations but do not pose an immediate threat to the patient's health and safety compared to the risk of infection.

Correct answer:

The correct answer is C: She has an excellent prognosis with surgery, chemotherapy, and radiation. Rationale: 1. Malignant rhabdoid tumor of the kidney (MRTK) is an aggressive cancer with poor prognosis. 2. Even with aggressive treatment, including surgery, chemotherapy, and radiation, the prognosis is generally poor due to high rates of recurrence and metastasis. 3. Therefore, stating that the patient has an excellent prognosis with the mentioned treatments is not true. Summary of other choices: A: Most patients with rhabdoid tumor of the kidney present in infancy - True, MRTK commonly presents in infancy. B: Most patients with rhabdoid tumor of the kidney present with metastatic (stage III or IV) disease - True, MRTK often presents with metastatic disease. D: Germline testing for SMARCB1/INI1 mutation on chromosome 22 is recommended, with brain MRI every 3 months until she is

Correct answer:

The correct answer is A because the patient's lipid profile indicates high LDL and low HDL levels, which increase the risk of cardiovascular disease. By discussing medications, dietary changes, and exercise, the nurse can address these lipid abnormalities effectively. Medications may be needed to lower LDL and raise HDL levels. Dietary changes, such as reducing saturated fats and increasing fiber intake, can help improve the lipid profile. Implementing an exercise regimen can also positively impact lipid levels. Choice B is incorrect because lifestyle changes are necessary to improve the patient's lipid profile. Choice C is incorrect as a high fat intake is not recommended for someone with elevated LDL levels. Choice D is incorrect as keeping a food diary and repeating laboratory work in 6 months may not address the immediate need for intervention to manage the patient's lipid levels.

Correct answer:

Certainly! The correct answer is B: Assess the client. Ventricular tachycardia may or may not require immediate intervention like defibrillation. Assessing the client's condition first allows the nurse to gather vital information such as the client's level of consciousness, vital signs, and overall stability. This assessment will guide the nurse in determining the appropriate next steps, which may include interventions like defibrillation, calling the physician, or administering treatment. Performing immediate defibrillation (choice A) without assessing the client's condition can be harmful if the client does not actually require it. Calling the physician (choice C) can be done after assessing the client to provide a comprehensive report. Administering a precordial thump (choice D) is not recommended in current guidelines and should not be the initial response to ventricular tachycardia.

Correct answer:

The correct answer is C: Observe serial hemoglobin values closely. The 5-year-old girl has a low hemoglobin level with normal white cells and platelets, suggestive of a chronic process. Given the normal physical exam, lack of symptoms, and negative workup for infection or hemolysis, it is reasonable to observe serial hemoglobin values closely. This approach allows monitoring for any trends or significant drops in hemoglobin levels, which may prompt further investigation or intervention. Administering erythropoietin (choice A) is not indicated as there is no evidence of bone marrow failure. Initiating a red cell transfusion (choice B) is not necessary as the patient is asymptomatic with no signs of acute blood loss. Prescribing oral iron supplement (choice D) is not appropriate as the patient has normal iron studies and mean corpuscular volume, indicating a non-iron deficiency etiology.

Correct answer:

The correct answer is D: Size and location of the aneurysm. Monitoring the size and location of the aneurysm is crucial in determining the risk of rupture. Larger aneurysms in critical locations are more likely to rupture. This information guides healthcare providers in making informed decisions about interventions to prevent rupture. Explanation of other choices: A: Medication therapy the client is receiving - While medication therapy may be important in managing symptoms or risk factors associated with an aneurysm, it does not directly indicate impending rupture. B: Client's usual blood pressure - Blood pressure management is important in preventing complications of an aneurysm, but it does not specifically signal impending rupture. C: Age and gender of the client - While age and gender may influence the risk of developing an aneurysm, they do not indicate impending rupture.

Correct answer:

The correct answer is D because in this scenario, the patient is experiencing symptoms of a transfusion reaction, likely a hemolytic transfusion reaction due to ABO incompatibility. The presence of a positive Direct Antiglobulin Test (DAT) for C3 indicates complement activation, supporting the diagnosis. Choice A (Spherocytes on peripheral blood smear) is incorrect as spherocytes are seen in autoimmune hemolytic anemia, not typically in transfusion reactions. Choice B (Gram-negative Bacillus on gram stain of remaining RBC unit) is unlikely as the symptoms are more indicative of a hemolytic reaction rather than an infection. Choice C (Chest x-ray with bilateral pulmonary infiltrates) is suggestive of transfusion-related acute lung injury (TRALI), but the symptoms described in the question (fever, chills, rigors) are more indicative of a hemolytic reaction rather than TRALI.
