LPN exams fundamentals practice questions set 39

Correct answer:

The correct answer is A: Encourage mutual goal setting. This intervention is crucial as it empowers the patient to take an active role in their care, promoting autonomy and self-efficacy. By involving the patient in setting goals, it helps them regain a sense of control and combat feelings of powerlessness. It also fosters a collaborative relationship between the patient and the healthcare team, enhancing trust and engagement in the treatment process. Incorrect choices: B: Verbally communicate empathy - While empathy is important, it does not directly address the issue of powerlessness. C: Reinforce participation in activities - While participation in activities can be beneficial, it may not address the underlying issue of powerlessness. D: Demonstrate an accepting attitude - While acceptance is important, it may not empower the patient to actively participate in their care and address feelings of powerlessness.

Correct answer:

The correct answer is C: Gastrointestinal distress is a common side effect. Rivastigmine is a cholinesterase inhibitor used to treat dementia. Gastrointestinal distress, such as nausea, vomiting, and diarrhea, is a common side effect due to increased cholinergic activity in the GI tract. This information is crucial for the patient and family to monitor and manage these symptoms. Rationale for why the other choices are incorrect: A: Hepatotoxicity and jaundice are not common side effects of rivastigmine. These side effects are more commonly associated with other medications. B: The initial dose of rivastigmine is typically lower, starting at 1.5 mg twice a day to minimize side effects. Starting at 6 mg three times a day would increase the risk of adverse effects. D: Increased appetite and weight gain are not typical side effects of rivastigmine. In fact, weight loss is more commonly reported with this medication.

Correct answer:

The correct answer is A because pericardial tamponade can lead to jugular vein distension due to the increased pressure in the pericardium, which can impede blood flow back to the heart. Hemorrhagic shock, on the other hand, does not typically cause jugular vein distension. This difference in jugular vein distension is a key clinical finding to differentiate between the two conditions. Choice B is incorrect because cyanosis to the face, neck, and upper chest can be present in both pericardial tamponade and hemorrhagic shock, making it less specific for distinguishing between the two. Choice C is incorrect because pericardial tamponade can also lead to hypotension due to decreased cardiac output, while hemorrhagic shock can sometimes lead to compensatory hypertension in its early stages. Choice D is incorrect because the type of tachycardia (narrow vs. wide complex) is not a reliable or consistent finding to

Correct answer:

The correct answer is B because using research findings to improve practice is a key component of a nurse with a baccalaureate degree. Baccalaureate-prepared nurses are expected to integrate evidence-based practice into their care delivery. This involves critically analyzing research findings to enhance patient outcomes and implement best practices. Nurses with a baccalaureate degree have a deeper understanding of research methodologies and the importance of evidence-based practice. Choice A (providing direct physical care) is not specific to a baccalaureate degree level and can be performed by nurses at various educational levels. Choice C (administering medications as prescribed) is a basic nursing responsibility that does not require a baccalaureate degree specifically. Choice D (collaborating with other healthcare providers) is important in nursing practice but is not exclusive to baccalaureate-prepared nurses.

Correct answer:

The primary therapeutic goal of dornase alfa (Pulmozyme) in cystic fibrosis is to thin and loosen mucus secretions. This enzyme helps break down the DNA in thick, sticky mucus, making it easier for the patient to clear their airways. By thinning the mucus, it reduces the risk of blockages, improves airway clearance, and enhances lung function. This directly addresses the underlying issue in cystic fibrosis, which is the buildup of thick mucus in the lungs. Other choices are incorrect because: A: While dornase alfa may indirectly help reduce lung inflammation by improving mucus clearance, its primary goal is not to directly reduce inflammation. C: While dornase alfa may reduce the risk of infections by improving mucus clearance, its primary goal is not to prevent bacterial infections. D: While improved mucus clearance may indirectly help with oxygen absorption, the primary goal of dornase alfa is specifically to

Correct answer:

Asbestos exposure is a well-documented occupational hazard causing pneumoconiosis, notably asbestosis, and lung cancer due to its fibrous particles lodging in lung tissue, triggering chronic inflammation and scarring. The occupational health nurse must assess this risk in industries like construction or shipbuilding, where asbestos was historically used. Organic acids may irritate airways but don't typically cause chronic lung disease like pneumoconiosis. Propane, a gas, poses asphyxiation or explosion risks, not direct lung parenchymal damage. Gypsum (calcium sulfate) is a dust irritant but lacks the fibrogenic potency of asbestos. Focusing on asbestos exposure via job history, duration, and protective measures enables the nurse to identify workers at risk for irreversible lung damage, facilitating early screening (e.g., spirometry, imaging) and prevention strategies like respirators, critical in occupational health.

Correct answer:

Within a muscle fiber, the sarcolemma, the cell membrane, extends inward as transverse tubules, known as T-tubules. These structures penetrate deep into the fiber, ensuring rapid transmission of action potentials from the nerve impulse to trigger contraction. This allows synchronized calcium release across the fiber, critical for muscle function. The sarcoplasmic reticulum, while closely associated, is a separate organelle storing calcium, not an extension of the sarcolemma. Myofibrils are the contractile units, composed of actin and myosin, but they don't extend from the membrane. Sarcomeres are segments of myofibrils, defining the contractile zone, not membrane extensions. T-tubules' role in signal conduction distinguishes them, enabling efficient, uniform contraction, unlike the storage, structural, or organizational roles of the others, aligning with their anatomical and physiological purpose in muscle activation.

Correct answer:

In cystic fibrosis (CF), pancreatic enzyme supplementation with meals is essential to enhance nutritional status, as 90% of patients have exocrine pancreatic insufficiency from CFTR mutations. Thick mucus blocks pancreatic ducts, preventing digestive enzymes (e.g., lipase, protease) from reaching the gut, causing malabsorption of fats and proteins supplements (e.g., pancrelipase) correct this, improving calorie uptake critical for growth in a 6-year-old. Small, frequent meals aid digestion but don't address enzyme deficiency alone. TPN, intravenous nutrition, is reserved for severe cases, not routine CF care. Magnesium, thiamine, and iron aren't typically deficient in CF; fat-soluble vitamins (A, D, E, K) are supplemented instead due to fat malabsorption. The nurse's inclusion of enzyme therapy dosed with meals and snacks optimizes nutrition, countering CF's gastrointestinal impact, vital for this child's development.

Correct answer:

The correct answer is D: Importance of sunscreen and avoiding direct sunlight. Rationale: 1. Oral hypoglycemic agents can increase sensitivity to sunlight, leading to sunburn or skin damage. 2. Diabetic patients are at higher risk of skin complications, so protecting the skin from sunlight is crucial. 3. Sun exposure can also affect blood sugar levels, potentially causing fluctuations in glucose levels. 4. Use of sunscreen and avoiding direct sunlight can help prevent skin issues and maintain overall health for a diabetic patient. Summary: A: Increased possibility of bruising - Not directly related to diabetes or oral hypoglycemic agents. B: Skin sensitivity as a result of exposure to salt water - Not a common concern for diabetic patients on oral hypoglycemic agents. C: Lack of availability of glucose-monitoring supplies - Important but not directly related to the side effects of oral hypoglycemic agents.

Correct answer:

The correct answer is C: Intracranial pressure 18 mm Hg. This is the most important information to communicate because changes in ICP can indicate increasing intracranial pressure, which can lead to serious complications such as brain herniation. Monitoring and promptly communicating any changes in ICP to the healthcare provider is crucial for timely intervention and prevention of further damage. Choice A: Oral temperature 102°F is important for assessing for signs of infection or inflammation, but it is not directly related to the intracranial pressure monitoring. Choice B: Apical pulse 102 beats/min is important for assessing cardiac function, but it is not directly related to intracranial pressure monitoring. Choice D: Mean arterial pressure 90 mm Hg is important for assessing perfusion to the brain, but it is not as directly relevant to intracranial pressure monitoring as the actual ICP reading itself.
