LPN Fundamentals Exam 1 Quizlet Questions
Question 1 of 5
The nurse is preparing to do a focused assessment of the abdomen on an assigned client. Which of the following is most important for the nurse to do prior to the examination?
Correct Answer: A
Rationale: Emptying the bladder before an abdominal assessment prevents distension from interfering with palpation or auscultation, most critical for accuracy. Equipment, position, and dressings follow. Nurses ensure this for reliable findings.
Question 2 of 5
Which physiological effect of immobility can lead to impaired circulation and increased risk of deep vein thrombosis?
Correct Answer: C
Rationale: Immobility reduces cardiac output by limiting muscle activity that aids venous return, leading to sluggish circulation and blood pooling, heightening deep vein thrombosis risk. This cardiovascular effect stems from less demand on the heart and poor venous flow, a serious concern in bedridden patients. Reduced breathing capacity affects oxygenation, not circulation directly, while muscle weakness and bone density loss impact strength and structure, not blood flow. Nurses monitor this to prevent clot formation, using interventions like leg exercises or compression devices, recognizing that circulation impairment is a critical link to thrombosis in prolonged stillness.
Question 3 of 5
Which intervention is important for preventing venous thromboembolism (VTE) in an immobile patient?
Correct Answer: A
Rationale: Encouraging ambulation and leg exercises prevents venous thromboembolism in immobile patients by boosting blood flow and reducing stasis, key to clot prevention. Sedatives increase immobility, cold compresses don't address circulation, and fluid limits harm hydration. Nurses implement this to counter VTE risk, using movement to enhance venous return, a critical strategy in immobile patient care.
Question 4 of 5
A nurse is caring for a client receiving oxygen therapy via a non-rebreather mask. What is an important nursing intervention for this client?
Correct Answer: A
Rationale: Ensuring the reservoir bag stays inflated (A) is critical for a non-rebreather, maintaining a high oxygen reserve (up to 95%) for inhalation. Client-preferred flow (B) lacks medical basis. Q2h SpO2 (C) may be too infrequent. Meal removal (D) disrupts therapy. Bag inflation, per respiratory care, ensures efficacy.
Question 5 of 5
A client with glaucoma has been prescribed Timoptic (timolol) eyedrops. Timoptic should be used with caution in the client with a history of:
Correct Answer: C
Rationale: Timoptic, a beta-blocker eyedrop for glaucoma, requires caution in clients with emphysema due to potential systemic absorption causing bronchoconstriction, exacerbating respiratory issues. Diabetes, ulcers, or pancreatitis aren't directly contraindicated beta-blockers more critically affect airway resistance. Nurses monitor breathing in such clients, ensuring safe use while managing intraocular pressure, balancing ocular benefits against pulmonary risks.
