Correct Answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

Correct Answer: A

Rationale: Scheduling rest periods during morning care is essential for managing dyspnea and fatigue in the client. This approach allows the client to pace themselves and catch their breath, promoting comfort and reducing symptoms. It is crucial to provide breaks to prevent overwhelming the client and exacerbating their symptoms. Discontinuing morning care for 2 days (choice B) is not a suitable solution as it does not address the underlying issue and may lead to neglect of essential care. Performing all care as quickly as possible (choice C) can worsen the client's symptoms and compromise their well-being by increasing stress and exertion. Asking a family member to bathe the client (choice D) does not address the need for rest periods during care and may not be feasible or appropriate in all situations.

Correct Answer: B

Rationale: Furosemide (Lasix) is the correct answer. In a client with heart failure experiencing weight gain and peripheral edema, the priority is to manage fluid overload. Furosemide is a loop diuretic commonly prescribed to reduce excess fluid in heart failure patients. Lisinopril (Zestril) is an ACE inhibitor used to treat hypertension and heart failure but does not directly address fluid overload. Metoprolol (Lopressor) is a beta-blocker that helps manage heart failure symptoms but does not primarily target fluid retention. Simvastatin (Zocor) is a statin used to lower cholesterol levels and is not indicated for managing fluid overload in heart failure.

Correct Answer: A

Rationale: The initial action the nurse should take after discovering a client's eviscerated wound is to cover the incision with a moist sterile dressing. This step is crucial to protect the exposed tissue, prevent infection, and create a conducive environment for healing. While notifying the surgeon is important, addressing the wound immediately takes precedence. Assessing vital signs is essential but should follow the immediate intervention of covering the wound. Placing the client in a supine position with knees bent is not the priority in managing an eviscerated wound; the first step is to cover the wound to protect the exposed tissue.

Correct Answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.
