Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

Correct Answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

Correct Answer: A

Rationale: The correct answer is to monitor daily weight. This method is the most accurate way to assess fluid balance in patients with kidney disease. Daily weight monitoring can detect even small changes in fluid balance, such as fluid retention or loss, which may not be evident through other methods. Monitoring input and output (choice B) is also important but may not provide a complete picture of fluid balance as it doesn't consider factors like insensible losses. Checking for edema (choice C) is a sign of fluid retention but may not always be present or may be difficult to assess accurately. Checking urine output (choice D) is important but may not reflect the overall fluid balance status of the patient.

Correct Answer: A

Rationale: The best position for a patient in respiratory distress is the Semi-Fowler's position. This position promotes lung expansion and eases breathing by allowing the chest to expand more fully. The Trendelenburg position (choice B) where the patient's feet are higher than the head is not recommended in respiratory distress as it may cause increased pressure on the chest and reduced lung expansion. The prone position (choice C) lying on the stomach is also not optimal for respiratory distress as it can further compromise breathing. The supine position (choice D) lying flat on the back is not ideal as it may impair breathing by restricting chest expansion.

Correct Answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.

Correct Answer: A

Rationale: Encouraging compliance through education is crucial in helping patients understand the importance of consistent medication use. By providing education, the patient can make informed decisions about their health and better manage their condition. Contacting the healthcare provider (choice B) may be necessary in some cases, but the initial approach should focus on patient education. Documenting the refusal (choice C) is important for legal and medical records but does not address the root cause of non-compliance. Exploring alternative treatment options (choice D) should come after efforts to educate and encourage compliance with the current medication regimen.
