LPN Fundamentals Exam 1 Quizlet Questions
Question 1 of 5
The nurse finds that a newborn has a mean systolic pressure of 75 mmHg. How would this blood pressure be best described?
Correct Answer: A
Rationale: A newborn's systolic pressure of 75 mmHg is normal (range 65-95), not low or high. Nurses assess this for neonatal stability.
Question 2 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 3 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 4 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.
Question 5 of 5
Which of the following symptoms is associated with exacerbation of multiple sclerosis?
Correct Answer: C
Rationale: Diplopia (double vision) is a frequent symptom during multiple sclerosis (MS) exacerbations, reflecting inflammation of optic or cranial nerves, disrupting coordination a hallmark of this demyelinating disease. Anorexia, seizures, or insomnia may occur but aren't as specific to MS flares. Nurses identify this visual disturbance to gauge relapse severity, guiding steroid or symptomatic treatment, and educate clients to report it, enhancing disease monitoring and quality of life.
