LPN exams fundamentals practice questions set 56

Correct answer:

Rectal temperature measurement is contraindicated in specific cases due to risks. For a newborn with hypothermia , its avoided due to fragile rectal tissue and potential perforation risk. A child with pneumonia has no specific rectal contraindication unless diarrhea is present, which isnt mentioned. An older adult post-myocardial infarction is at risk because thermometer insertion can stimulate the vagus nerve, slowing the heart rate, which is dangerous post-MI. A teenager with leukemia may have neutropenia, making rectal measurement risky due to infection potential from low white blood cell counts. Choice C is highlighted as correct in the context, supported by the vagus nerve risk. Other contraindications like rectal surgery or low platelets also apply but align with Cs cardiac focus here. This reflects nursing judgment in prioritizing patient safety based on physiological risks.

Correct answer:

The correct answer is A because the American Nurses Association (ANA) believes that it is the nursing profession itself that should have the authority to determine the scope of nursing practice. This principle emphasizes the importance of nursing professionals being actively involved in defining and regulating their own practice. Choice B is incorrect because while RNs may have a role in supervising unlicensed assistive personnel, it is not solely the responsibility of the RN to define and supervise the education and training of NAPs. Choice C is incorrect because ultimate responsibility and accountability for nursing practice lies with the licensed nurse, not the unlicensed NAP. Choice D is incorrect because the purpose of the RN is not just to work in a supportive role to assistive personnel; rather, it is to provide comprehensive nursing care and lead the nursing team.

Correct answer:

Inviting the adolescent to participate in group activities aligns with Erikson's theory of psychosocial development, specifically the stage of developing social relationships. By engaging in group activities, the adolescent can interact with peers, fostering social skills and aiding in adjustment to the hospital environment. Choice B is incorrect as excessive reliance on phone calls to parents may hinder the adolescent's autonomy and independence, which are crucial aspects of Erikson's theory for this age group. Choice C, providing access to video games, while potentially offering entertainment, does not directly address the need for social interaction and relationship-building. Choice D, encouraging the adolescent to learn his way around the hospital, is important for familiarity but may not directly address the need for social interaction and adjustment in the hospital setting.

Correct answer:

The correct answer is B: linea nigra. The linea nigra is a darkened pigmented line that runs from the symphysis pubis to the sternum in pregnant individuals. This line is a normal finding in pregnancy due to hormonal changes. It is important for the nurse to document this finding accurately as it is a common physiological change. Rationale: 1. Cholasma (A) is also known as the mask of pregnancy, presenting as dark patches on the face. 2. Spider nevi (C) are small, dilated blood vessels on the skin, not related to the linea nigra. 3. Striae gravidarum (D) are stretch marks that occur due to rapid stretching of the skin during pregnancy, not related to the pigmented line. In summary, the correct answer is B because the darkened line described is characteristic of linea nigra, a common finding in pregnancy, while the other choices are unrelated to this specific observation.

Correct answer:

When a nurse faces a trial under criminal law, it involves a legal action initiated by the state or government, representing society as a whole, rather than a private entity or individual. Criminal law addresses offenses deemed harmful to the public, such as negligence causing harm or intentional misconduct. Unlike civil cases, where an individual or organization might sue for damages, criminal cases are prosecuted by the state to uphold public safety and justice. The nurse's actions are evaluated against legal standards that protect society, making this the most accurate description. Other options, like the plaintiff's lawyer or an individual, pertain more to civil litigation, while an organization might be involved in internal discipline but not a criminal trial. This distinction is critical in understanding the scope and authority behind criminal proceedings in nursing practice.

Correct answer:

After pulmonary embolus (PE) resolution, the home care nurse prioritizes monitoring for residual effects of compromised oxygenation, such as fatigue, cognitive deficits, or exertional dyspnea, stemming from prolonged hypoxia during the acute phase. PE obstructs pulmonary arteries, impairing gas exchange, and even post-treatment, lung tissue recovery may lag, leaving subtle deficits. Pulmonary infection isn't a direct PE sequela unless secondary pneumonia develops, which isn't indicated. Swallowing issues or aspiration aren't linked to PE unless unrelated comorbidities exist. Activity level and role performance matter but are secondary to oxygenation status, which underpins functional capacity. Close monitoring via pulse oximetry, symptom reports, or exertion tolerance ensures the nurse detects lingering hypoxia effects, guiding rehabilitation or oxygen therapy to optimize recovery.

Correct answer:

Nursing research aims to enhance the profession's impact on patient care through targeted purposes. Providing a basis for best practice guidelines is central, as research synthesizes evidence like clinical reviews into actionable standards, ensuring care is effective and current. Developing new ways to improve assessment and diagnostic skills sharpens nurses' ability to identify and address client needs, driving innovative tools or techniques. It also supports evaluating care, offering resources to measure intervention success, and informs planning by setting evidence-based goals. Decreasing illnesses aligns more with medical research, while improving NCLEX pass rates pertains to education, not research's core. These purposes collectively advance nursing knowledge, refine practice, and elevate client outcomes, grounding the profession in science rather than tradition or assumption.

Correct answer:

The correct action for the nurse to take in this situation is to complete the intermittent suction of the nasopharynx. Since the oxygen saturation remains stable at 94%, which was the initial reading, it indicates that the procedure is not causing a significant drop in oxygen levels. Stopping the suctioning or applying oxygen may not be necessary as the saturation level is within an acceptable range. Repositioning the pulse oximeter clip is unlikely to change the reading significantly. Therefore, completing the procedure maintains care consistency and effectiveness, ensuring proper airway management without unnecessary interventions. Choices B, C, and D are incorrect because repositioning the pulse oximeter clip, stopping suctioning until a higher reading is achieved, and applying oxygen are not warranted based on the stable oxygen saturation level of 94% throughout the procedure.

Correct answer:

Non-sterile specimens come from areas of the body naturally colonized by microbes, while sterile specimens are from normally microbe-free sites. 'Urine,' is the correct answer as the exception because, in a healthy individual, urine in the bladder is sterile until it reaches the urethra, where contamination may occur. Choices A, 'Nasal secretion,' B, 'Vaginal secretion,' and D, 'Vomitus,' are non-sterile, as the nasal passages, vagina, and gastrointestinal tract harbor normal flora (e.g., Staphylococcus in the nose, Lactobacillus in the vagina). Microbiology standards, like those in clinical lab manuals, classify urine as potentially sterile when collected midstream, unlike the others, which are inherently non-sterile due to resident bacteria. The question's focus on non-sterile specimens' excludes urine's typical sterility in the upper urinary tract, making C the standout answer.

Correct answer:

Childhood cancers often present with subtle, non-specific signs, but swellings, lumps, or masses anywhere on the body are a key early warning, indicating possible tumors like leukemia (lymphadenopathy), Wilms tumor, or sarcomas. Nurses must assess these palpable abnormalities, as they prompt urgent diagnostic workup imaging or biopsy to catch cancer early when treatment is most effective. Difficulty swallowing might suggest esophageal or brain tumors but isn't a common early childhood cancer sign. Frequent cough or hoarseness could indicate adult cancers (e.g., lung) or late-stage disease, not typical pediatric onset. Bowel and bladder changes are more adult-specific (e.g., colorectal cancer) or late effects in children. Lumps' prominence in pediatric guidelines underscores their priority, aligning with nursing's role in early detection to improve survival rates in young patients.
