LPN exams safety and infection control practice questions set 3

Correct answer:

The correct answer is B: Cardiac output and blood pressure. In ARDS patients on high PEEP, monitoring cardiac output and blood pressure is crucial due to the risk of hemodynamic compromise. High PEEP can decrease venous return, leading to decreased cardiac output and hypotension. Monitoring these parameters helps detect and prevent complications like hypotension, which can further compromise oxygenation. Choice A is incorrect because while monitoring respiratory rate and depth is important in ARDS, the priority in this scenario is monitoring hemodynamic status due to the potential impact of high PEEP on cardiac function. Choice C is incorrect as monitoring white blood cell count is not directly related to complications of high PEEP in ARDS patients. Choice D is incorrect because sputum production and characteristics are not the priority for monitoring in this scenario; cardiac output and blood pressure are more critical indicators of potential complications.

Correct answer:

The correct answer is D: Nonmaleficence. The nurse's refusal to disclose the surgeon's medical diagnosis upholds the ethical principle of nonmaleficence, which is to do no harm. By maintaining the surgeon's confidentiality, the nurse is protecting the surgeon from potential harm or breach of privacy. This action demonstrates respect for the surgeon's autonomy and promotes trust in the nurse-patient relationship. Choices A, B, and C are incorrect: A: Utility - Utility refers to maximizing benefits for the greatest number of people. In this scenario, the nurse's action does not relate to maximizing benefits. B: Paternalism - Paternalism involves making decisions for someone else's well-being without their consent. The nurse's action is not an example of paternalism as the surgeon's privacy is being respected. C: Justice - Justice involves fairness and equal treatment. The nurse's response does not directly relate to the ethical principle of justice in this context.

Correct answer:

The correct answer is B: The determinants of health. This is an appropriate starting point for the application of a population health approach because understanding the determinants of health helps identify the root causes of health disparities and population health outcomes. By focusing on social, economic, and environmental factors that influence health, interventions can be targeted effectively to improve overall health outcomes for a population. Incorrect choices: A: Emergency life-saving care is not an appropriate starting point for a population health approach as it focuses on individual treatment rather than addressing broader population-level factors. C: Health promotion models are important in promoting health but may not address the underlying determinants of health necessary for a population health approach. D: Risk management focuses on minimizing risks rather than addressing the broader determinants of health needed for a population health approach.

Correct answer:

The correct answer is B: Risk for other-directed violence R/T yelling accusations. This is the priority nursing diagnosis because the student's behavior of yelling accusations at fellow students indicates a potential risk for harm towards others. It is crucial to address this immediate safety concern to prevent any harm to others. A: Altered thought processes R/T hearing voices AEB increased anxiety is incorrect because while altered thought processes may be present, the immediate safety concern of potential violence towards others takes priority. C: Social isolation R/T paranoia AEB absence from classes is incorrect because although social isolation and paranoia are present, the immediate risk of harm towards others is more critical to address first. D: Risk for self-directed violence R/T depressed mood is incorrect because the student's behavior is directed towards others, not towards themselves. The immediate concern is the risk of harm towards others.

Correct answer:

The correct answer is B: The client is expressing a neologism. Neologism refers to the creation of new words or phrases that are not understandable to others. In this case, "Shopatoulens" is a nonsensical word created by the client. This response is appropriate as it accurately describes the client's statement. A: The client is experiencing command hallucinations - This choice is incorrect as command hallucinations involve hearing voices that command the individual to do something. The client's statement does not indicate this. C: The client is experiencing a paranoid delusion - This choice is incorrect as a paranoid delusion involves irrational beliefs of being persecuted or targeted. The client's statement does not reflect this type of delusion. D: The client is verbalizing a word salad - This choice is incorrect as word salad refers to jumbled, incoherent speech. The client's statement, while nonsensical, is not completely incoherent like word salad.

Correct answer:

The correct answer is A. Transporting a school-age client who is in traction to another department is unsafe for a volunteer as it involves moving a patient with a specific medical condition that requires careful handling and knowledge of proper techniques to prevent injury. The volunteer may not be trained in how to safely transport a patient in traction, which could lead to harm for the patient. Choice B is incorrect because playing a computer video game with an adolescent who has sickle cell disease is a safe and appropriate activity for a volunteer to engage in to provide companionship and distraction for the patient. Choice C is incorrect because reading a book to a preschool client who has AIDS is a safe and appropriate activity that can help provide comfort and support to the patient. Choice D is incorrect because rocking an infant who was admitted for croup is a safe and appropriate activity that can help soothe the infant and provide comfort.

Correct answer:

Step 1: Delirium is characterized by acute onset confusion, agitation, hallucinations, and disorientation, which align with the patient's symptoms. Step 2: The patient's sudden change in mental status suggests an acute condition rather than a chronic one like dementia. Step 3: The inability to recognize her daughter and mistaking her for a stranger are typical features of delirium. Step 4: The daughter's report of sudden confusion and hallucinations points towards delirium rather than worsening dementia or new-onset dementia. Step 5: Therefore, based on the acute onset of symptoms and the patient's confusion and hallucinations, the nurse correctly suspects delirium. Summary: - B: Depression does not typically present with acute confusion, hallucinations, and disorientation. - C: New-onset dementia would not manifest suddenly with confusion and hallucinations. - D: Worsening dementia would show a gradual decline rather than a sudden onset of symptoms.

Correct answer:

Rationale for Correct Answer B: The nurse's signature on the consent form confirms the client appears competent to provide consent. This is important as it ensures the client has the capacity to make informed decisions about their care. The nurse assesses the client's ability to understand the information provided regarding the procedure and its risks and benefits. By signing as a witness, the nurse acknowledges that the client is mentally competent to provide consent. Summary of Incorrect Choices: A: Incorrect. The nurse's signature does not determine if the client has a mental illness. This falls under the purview of the healthcare provider, not the nurse. C: Incorrect. While the nurse may have explained the risks and benefits, this is not the sole purpose of the nurse's signature on the consent form. D: Incorrect. The nurse's signature does not indicate the client's spouse agrees with the procedure; this is not the nurse's role in the consent process.

Correct answer:

During the recovery phase of the disaster management cycle, the community nurse would focus on reducing the spread of communicable diseases. This is because in the aftermath of a disaster, there is an increased risk of disease outbreaks due to compromised sanitation and living conditions. By implementing measures such as vaccination campaigns, promoting hygiene practices, and monitoring for disease symptoms, the nurse can help prevent the spread of communicable diseases and protect the community's health. - Choice A: Performing triage and emergency care is typically done during the response phase to address immediate medical needs. - Choice B: Educating families on disaster preparedness is important during the preparedness phase to help communities be better equipped for future disasters. - Choice D: Performing triage and transporting victims is also part of the response phase to provide immediate medical attention and transfer to appropriate services.

Correct answer:

The correct principle involved in this situation is beneficence. Beneficence is the ethical principle that emphasizes the duty to do good and promote the well-being of others. In this case, the administration of immunizations may cause discomfort to the child, but the benefits of protection from diseases outweigh this temporary discomfort. By choosing to immunize the child, the healthcare provider is acting in the child's best interest to prevent future harm from potentially deadly diseases. This decision aligns with the principle of beneficence. A: Fidelity pertains to being faithful and keeping promises, which is not directly relevant to this situation. C: Nonmaleficence is the principle of doing no harm, but in this case, the temporary discomfort of immunization is outweighed by the long-term benefits. D: Respect for autonomy refers to respecting an individual's right to make their own decisions, which is not the primary focus in this scenario.
