NUR170 | NUR 170 Exam 2 | Medical-
Surgical Nursing Concepts Exam | Study
Questions and Correct Answers | Verified
and Rated A+ | 2025/2026 Guide
Gas Exchange - Correct Answer - O2 and CO2 exchange via alveolar-
capillary membrane.
HTN Education - Correct Answer - Medication adherence, low sodium,
exercise, avoid tobacco.
Pneumonia Care Plan (Elderly) - Correct Answer - Antibiotics, hydration,
mobility, oral care, monitor confusion as early sign.
ECG Components - Correct Answer - P wave: Atrial depolarization.
QRS: Ventricular depolarization. T wave: Ventricular repolarization.
Atrial Fibrillation - Correct Answer - Irregularly irregular rhythm; atria
quiver. Tx: Rate control (BB/CCB), rhythm control (amiodarone),
anticoagulation.
Thrombocytopenia Nursing Care - Correct Answer - Avoid invasive
procedures. Monitor for bleeding, educate on bleeding precautions.
, Angina Types - Correct Answer - Stable: Triggered by exertion, relieved
by rest/nitro. Unstable: Occurs at rest, precursor to MI.
Quick relief - Correct Answer - Albuterol.
Long-term - Correct Answer - Inhaled corticosteroids, LABAs.
Asthma Prioritization - Correct Answer - Assess ABCs. Administer
bronchodilator, position upright.
COPD Interventions - Correct Answer - Pursed-lip breathing, low-flow
oxygen, tripod position, encourage fluids.
Sputum Reduction - Correct Answer - Expectorants (guaifenesin),
mucolytics, hydration.
Emphysema Patho - Correct Answer - Alveolar destruction, reduced
surface area for gas exchange → air trapping.
PAD Teaching - Correct Answer - Foot care, no smoking, exercise until
claudication.
