Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

3. A client who had a vasectomy is in the post-recovery unit at an outpatient clinic. Which of these points is most important to be reinforced by the nurse?

• A. Until the healthcare provider has determined that your ejaculate doesn't contain sperm, continue to use another form of contraception.
• B. This procedure doesn't impede the production of male hormones or the production of sperm in the testicles. The sperm can no longer enter your semen, and no sperm are in your ejaculate.
• C. After your vasectomy, strenuous activity needs to be avoided for at least 48 hours. If your work doesn't involve hard physical labor, you can return to your job as soon as you feel up to it. The stitches generally dissolve in seven to ten days.
• D. The healthcare provider at this clinic recommends rest, ice, an athletic supporter, or over-the-counter pain medication to relieve any discomfort.

Correct answer: A

Rationale: The most important point to reinforce after a vasectomy is to continue using contraception until the healthcare provider confirms the absence of sperm in the ejaculate. Choice A is correct because it emphasizes the necessity of another form of contraception until sperm absence is confirmed. Choice B is incorrect because it focuses on how a vasectomy works anatomically rather than the need for ongoing contraception. Choice C is incorrect as it discusses post-vasectomy care but does not address the need for continued contraception. Choice D is also incorrect as it refers to general post-procedure recommendations but does not highlight the crucial aspect of using contraception until sperm absence is confirmed.

4. The nurse is providing education to a client who experiences recurrent levels of moderate anxiety in response to situations and perceived stress. In addition to information about prescribed medication and administration, which instruction should the nurse include in the teaching?

• A. Practice using muscle relaxation techniques
• B. Take medication only when anxiety is at its worst
• C. Avoid interactions that trigger stress
• D. Engage in exercise during anxious periods

Correct answer: A

Rationale: Teaching relaxation techniques, such as muscle relaxation, helps the client manage anxiety more effectively. These techniques can be practiced regularly to reduce overall anxiety and can complement prescribed medications. Choice B is incorrect because medication should be taken as prescribed, not only when anxiety is at its worst. Choice C is incorrect as avoiding interactions that trigger stress may not always be feasible and does not teach the client coping mechanisms. Choice D is incorrect as engaging in exercise during anxious periods may not be the most effective strategy for managing moderate anxiety levels.

5. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.
