LPN exams fundamentals practice questions set 102

Correct answer:

Correct Answer: C - Transactional leadership Rationale: 1. Transactional leadership focuses on motivating employees through rewards and incentives, such as the movie and pizza outing for perfect attendance. 2. The approach emphasizes the exchange of rewards for performance, leading to improved employee engagement and motivation. 3. In this scenario, the nurse manager is using rewards to encourage desired behavior, reflecting the principles of transactional leadership. Summary: A: Principle-centered leadership emphasizes values and ethics as guiding principles, not directly related to the use of rewards. B: Transformational leadership inspires and motivates through a vision, not specifically through rewards. D: Functional leadership focuses on task efficiency and coordination, not on motivating through rewards.

Correct answer:

The correct answer is A: Encourage the patient to sit in a chair and lean forward. This position helps improve ventilation by expanding the chest cavity, allowing for better lung expansion and increased air exchange. Leaning forward also reduces pressure on the diaphragm, making it easier for the patient to breathe. Choice B (head elevated 15 degrees) does not provide as much chest expansion as leaning forward. Choice C (Trendelenburg position) places the patient with their head lower than the feet, which can worsen breathing difficulties. Choice D (high-Fowler’s position with knees flexed) does not promote optimal lung expansion compared to leaning forward. In summary, choice A is the best option as it maximizes chest expansion and supports ventilation in a patient with poor gas exchange due to COPD.

Correct answer:

In the Agent-Host-Environment Model, Staphylococcus is the agent the causative factor triggering illness, here infecting a decubitus ulcer. The client is the host, whose skin integrity and immunity determine susceptibility. The environment bedridden conditions or hygiene sets the stage for infection. The disease is the resulting pathology, like the ulcer's worsening. This model dissects causation: Staphylococcus (bacteria) invades the host (client) in a conducive environment (immobility), driving nursing interventions cleaning wounds, repositioning to disrupt the triad. Understanding the agent's role guides targeted care, like antibiotics, breaking the infection cycle. It's a practical lens for nurses, pinpointing external triggers to prevent or manage illness effectively, especially in chronic wound scenarios.

Correct answer:

The correct answer is B: Check compatibility of the medication and IV fluids. Before administering the medications, it is crucial to ensure compatibility to prevent any adverse reactions or inactivation of the drugs. Checking compatibility involves verifying if the medications can be safely mixed and administered through the same IV line. This step helps in maintaining the effectiveness of the medications and ensuring patient safety. Summary: - Starting a second IV site (Choice A) is not necessary unless compatibility issues arise. - Mixing the prepackaged piperacillin/tazobactam per agency policy (Choice C) should only be done after verifying compatibility. - Priming the tubing with the IV solution and back-priming the medication (Choice D) should be done after confirming compatibility to avoid wastage.

Correct answer:

The correct answer is A because it accurately distinguishes between schizoid and avoidant personality disorders. Schizoid individuals prefer to be alone and lack desire for close relationships, while avoidant individuals desire intimacy but fear rejection. Choice B is incorrect because schizoid personality disorder does not necessarily involve odd or eccentric behavior, and avoidant personality disorder can involve social inhibition. Choice C is incorrect because avoidant personality disorder does not involve eccentric behavior, and schizoid personality disorder does not necessarily make individuals dull or vacant. Choice D is incorrect because schizoid personality disorder is not characterized by psychotic thought processes, and avoidant personality disorder is not necessarily more rooted in reality.

Correct answer:

The correct answer is A because highly bound drugs (98% bound) do not have clinically significant drug-drug interactions through displacement from binding sites on plasma proteins. This is because only the unbound (free) fraction of a drug is pharmacologically active and available for interactions. Highly bound drugs are bound to proteins and not readily available for interactions. Regarding the other choices: B: Only free drugs can pass through glomerular filtration - Correct, as only unbound drugs can be filtered through the kidneys. C: Only free drugs become available for hepatic metabolism - Correct, as only unbound drugs can undergo metabolism in the liver. D: Only free drugs can distribute to peripheral tissues - Correct, as only unbound drugs can leave the bloodstream and reach peripheral tissues.

Correct answer:

The most important intervention for the LPN/LVN to implement for a male client experiencing urinary retention is to assess for bladder distention. This assessment is crucial as it helps identify the underlying cause of urinary retention, such as bladder distention or obstruction. By assessing the bladder, the LPN/LVN can determine the appropriate interventions needed, such as catheterization, medication administration, or further evaluation by the healthcare provider. Applying a condom catheter (Choice A) is more suitable for urinary incontinence, not retention. Applying a skin protectant (Choice B) is typically done to prevent skin breakdown in incontinent clients. Encouraging increased fluid intake (Choice C) may be beneficial for some urinary issues but is not the priority intervention for urinary retention.

Correct answer:

Insulin lowers blood sugar in type 1 diabetes by enhancing glucose uptake into peripheral tissues like muscle and fat via GLUT4 transporters, while also inhibiting glycogenolysis in the liver, preventing stored glycogen from breaking down into glucose. This dual action stabilizes blood glucose by promoting storage and reducing release. It also suppresses gluconeogenesis, but this is secondary to its primary effects on uptake and glycogen preservation. Intestinal absorption isn't directly affected; that's more relevant to oral agents like metformin. The nurse's response should emphasize these key mechanisms facilitating cellular glucose entry and halting liver glucose output reflecting insulin's critical role in managing hyperglycemia effectively, aligning with its physiologic action in insulin-deficient states.

Correct answer:

Patients with angina pectoris commonly experience symptoms that are similar to indigestion after eating a heavy meal. This is because angina is caused by reduced blood flow to the heart muscles due to coronary artery disease. The discomfort from angina can be triggered by activities that increase the heart's workload, such as eating a large meal that requires increased blood flow to the digestive system. The pain or discomfort associated with angina can feel like a squeezing sensation in the chest, often described by patients as similar to heartburn or indigestion. Therefore, the nurse can expect a patient with angina pectoris to experience feelings of indigestion after eating a heavy meal. It is important for healthcare providers to recognize these symptoms to provide appropriate care and treatment for angina.

Correct answer:

Correct Answer: A Rationale: 1. Moderate caffeine intake is generally considered safe during preconception as excessive intake may affect fertility. 2. Studies show that moderate caffeine consumption doesn't significantly impact fertility. 3. Advising complete elimination may be overly restrictive and challenging for patients. 4. Caffeine can affect both male and female fertility, not just male fertility. 5. Emphasizing moderation allows for informed decision-making and realistic lifestyle changes. Summary of other choices: B: Incorrect - Caffeine does not improve ovulation or increase conception chances. C: Incorrect - Complete elimination of caffeine is unnecessary for successful conception. D: Incorrect - Caffeine intake can affect both male and female fertility, not limited to male fertility.
