A nurse is reinforcing teaching with a client who asks which diagnostic test is the preferred method for detecting cervical cancer. Which is an appropriate response by the nurse?

a. Prothrombin time (PT): Warfarin affects the extrinsic pathway of the coagulation cascade, and PT is the primary diagnostic test used to monitor the therapeutic effect of warfarin. It measures

the time it takes for blood to clot.

b. Platelet count: Platelet count assesses the number of platelets in the blood and is not specifically used to monitor the effect of warfarin.

c. White blood cell count (WBC): WBC count assesses the number of white blood cells and is not specifically used to monitor the effect of warfarin.

d. Activated partial thromboplastin time (aPTT): While aPTT is a valuable test for monitoring the therapeutic effect of heparin, it is not the primary test for warfarin. Warfarin primarily affects the extrinsic pathway, and PT is more appropriate for monitoring its effects.

a. Rest in a supine position: Resting in a supine position may compromise lung expansion, and an upright position is often recommended for clients with emphysema to improve ventilation.

b. Breathe in through her nose and out through pursed lips: This technique helps maintain

positive airway pressure, preventing premature airway collapse, and can improve gas exchange in clients with emphysema.

c. Limit fluid intake throughout the day: Adequate hydration is important for maintaining

respiratory secretions in a liquefied state and is generally encouraged for clients with respiratory conditions.

d. Consume a low-protein diet: A low-protein diet is not specifically indicated for improving gas exchange in clients with emphysema. Nutrition recommendations may focus on a well-balanced diet to support overall health.
