LPN exams fundamentals practice questions set 110

Correct answer:

The correct answer is C: Evaporation and precipitation. These two processes are fundamental to the hydrological cycle. Evaporation is the process where water is converted from liquid to vapor and enters the atmosphere, while precipitation is when water vapor condenses and falls back to the Earth as rain, snow, sleet, or hail. This cycle is essential for maintaining Earth's water balance. A: Coagulation and sedimentation are processes used in water treatment to remove impurities, but they are not part of the hydrological cycle. B: Filtration and disinfection are also water treatment processes and do not directly involve the movement of water through the hydrological cycle. D: Chlorination and fluorination are methods used for water disinfection but do not play a role in the natural hydrological cycle.

Correct answer:

Teaching a diabetic client daily foot inspections is tertiary prevention, managing an existing condition to prevent complications like ulcers or amputations. Diabetes is chronic, and this intervention post-diagnosis focuses on reducing further harm by catching skin issues early, a common risk due to neuropathy. Primary prevention, like diet to avoid diabetes, precedes onset. Secondary prevention screens for initial signs, not ongoing care. 'Chronic' isn't a level. Nursing's tertiary role here empowers self-monitoring, critical since poor circulation masks injuries studies show inspections slash amputation rates. This aligns with chronic disease management, ensuring the client maintains function and avoids escalation, reflecting nursing's emphasis on practical, preventive care within an established illness.

Correct answer:

Repositioning an immobile patient primarily aims to prevent pressure ulcers by relieving pressure on skin over bony areas, like the sacrum or heels, and enhancing blood flow. Prolonged immobility risks tissue breakdown due to constant compression, making regular movement a cornerstone of preventive care in nursing. While shifting positions can secondarily support joint mobility, this isn't the main goal specific exercises target that more effectively. Building muscle strength requires active effort beyond repositioning, and though respiratory benefits may occur, they're addressed through targeted interventions like breathing exercises. This focus on skin integrity reflects nursing's priority to mitigate a common, severe complication of immobility, ensuring patient safety and comfort through proactive care.

Correct answer:

The correct answer is A: Instruct the client to use pursed-lip breathing. Pursed-lip breathing helps improve ventilation and reduce shortness of breath in COPD clients. This technique involves inhaling slowly through the nose and exhaling through pursed lips. Choice B is incorrect because a high-fat, low-carbohydrate diet is not recommended for individuals with COPD as it can lead to weight gain and worsen respiratory function. Choice C is incorrect as limiting physical activity can lead to deconditioning and worsen COPD symptoms. Regular, moderate exercise is beneficial for individuals with COPD. Choice D is incorrect as excessive fluid intake can strain the heart in COPD clients. It is important to maintain adequate but not excessive fluid intake to prevent dehydration and maintain optimal lung function.

Correct answer:

The correct answer is B: Follicular phase. This phase of the ovarian cycle is characterized by the development and maturation of ovarian follicles, which contain the eggs. During this phase, the primary follicle develops into the secondary and then the mature Graafian follicle. This is when follicle-stimulating hormone (FSH) stimulates the growth of the follicles. The other choices, such as A (Luteal phase), C (Secretory phase), and D (Proliferative phase), do not involve follicle growth. The luteal phase follows ovulation and is characterized by the development of the corpus luteum. The secretory phase is part of the uterine cycle, involving endometrial preparation for implantation. The proliferative phase is also part of the uterine cycle, involving endometrial thickening under the influence of estrogen.

Correct answer:

The correct answer is C: To identify and change negative thought patterns that contribute to anxiety. In CBT for anxiety disorders, the main goal is to challenge and modify distorted thinking patterns that contribute to anxiety. By identifying and changing negative thought patterns, individuals can learn to respond to situations in a more adaptive and less anxiety-provoking way. This approach helps to break the cycle of anxiety and improve coping skills. Choices A and D are incorrect because avoiding stress or accepting anxiety as inevitable do not address the underlying cognitive processes that contribute to anxiety. Choice B is also incorrect as gaining insight into unconscious causes is more aligned with psychodynamic therapy rather than CBT, which focuses on changing current thoughts and behaviors.

Correct answer:

Regular range-of-motion exercises are vital to prevent complications like joint stiffness, muscle atrophy, and blood clots in patients with limited mobility post-surgery. These exercises maintain circulation and flexibility, countering the risks of prolonged stillness. Avoiding hydration increases dehydration risk and doesn't address immobility's effects it's counterproductive. Keeping the patient supine at all times exacerbates immobility issues, potentially leading to pressure ulcers or respiratory problems. Minimizing communication might reduce stress but doesn't tackle physical complications. Nurses use active or passive exercises depending on the patient's ability, ensuring joints stay functional and reducing the likelihood of thromboembolism or contractures, which are serious post-operative concerns.

Correct answer:

Infants of mothers with gestational diabetes, especially macrosomic ones (over 4000 g), are at risk for hypoglycemia due to excess insulin production in utero from maternal hyperglycemia. Obtaining a serum neonatal glucose level is the priority, as it identifies hypoglycemia (typically <40 mg/dL) early, allowing timely intervention like feeding or IV glucose. Preparing insulin is inappropriate, as the issue is low, not high, glucose. Teaching nutritional needs is secondary to acute stabilization. Feeding D50W is a treatment, not an assessment, and requires a glucose check first to avoid unnecessary intervention. The nurse's focus is on detecting and correcting hypoglycemia, a common complication in this scenario, ensuring the neonate's metabolic stability post-delivery aligns with neonatal care priorities.

Correct answer:

Dry mucous membranes and hypotension are key indicators of dehydration in clients with diabetes insipidus. The excessive urination associated with DI can lead to fluid loss, resulting in dehydration. Therefore, monitoring for signs such as dry mucous membranes and hypotension is crucial to assess the client's hydration status. Choices B, C, and D are not directly related to the characteristic symptoms of DI and are less relevant in the context of this condition. Decreased appetite and headache (Choice B) are nonspecific symptoms that may occur in various conditions. Nausea, vomiting, and muscle weakness (Choice C) are not typical manifestations of DI. Elevated blood pressure and petechiae (Choice D) are not commonly associated with DI; instead, hypotension is more commonly observed due to volume depletion.

Correct answer:

The correct answer is B: Acute Care. The Romanow Report highlighted the importance of shifting emphasis in health care towards preventive and community-based services rather than focusing solely on acute care. Acute care is essential for treating serious and urgent medical conditions, but the report emphasized the need to prioritize other areas such as home care, primary health care reform, and palliative care to improve overall health outcomes and reduce healthcare costs. By investing in these areas, the healthcare system can better address the needs of individuals across the continuum of care, promote wellness, and enhance the quality of life for patients. The other choices (A, C, D) are included in the report as key areas for reform to achieve a more holistic and sustainable healthcare system in Canada.
