1. A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?
- A. aPTT 75 seconds.
- B. INR 1.2.
- C. Hemoglobin 10 g/dL.
- D. Fibrinogen level 350 mg/dL.
Correct answer: A
Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.
2. A healthcare provider is assessing a child who is being treated for bacterial pneumonia. The provider notes an increase in the child's glucose level. The provider should identify this finding as an adverse effect of which of the following medications?
- A. Methylprednisolone.
- B. Ondansetron.
- C. Guaifenesin.
- D. Amoxicillin.
Correct answer: A
Rationale: Correct. Methylprednisolone, a corticosteroid, can lead to increased glucose levels as an adverse effect. Ondansetron is an antiemetic and does not typically cause elevated glucose levels. Guaifenesin is an expectorant and is not associated with raising glucose levels. Amoxicillin is an antibiotic and does not affect glucose levels.
3. A nurse is caring for a client who is in labor and requires augmentation of labor. Which of the following conditions should the nurse recognize as a contraindication to the use of oxytocin?
- A. Diabetes mellitus
- B. Shoulder presentation
- C. Postterm with oligohydramnios
- D. Chorioamnionitis
Correct answer: B
Rationale: Shoulder presentation is a contraindication for oxytocin because it can increase the risk of complications during labor, such as shoulder dystocia. Diabetes mellitus (Choice A) is not a contraindication for the use of oxytocin. Postterm with oligohydramnios (Choice C) and chorioamnionitis (Choice D) may actually necessitate the use of oxytocin to induce or augment labor for the well-being of the mother and baby.
4. A client has a new prescription for spironolactone. Which of the following instructions should the nurse include?
- A. Take this medication with a potassium supplement.
- B. Avoid foods that contain potassium.
- C. Limit your fluid intake while taking this medication.
- D. Take this medication on an empty stomach.
Correct answer: B
Rationale: The correct answer is B because spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium. Instructing the client to avoid foods high in potassium helps prevent hyperkalemia, a potential side effect of spironolactone. Choice A is incorrect because taking spironolactone with a potassium supplement can increase the risk of hyperkalemia. Choice C is not directly related to spironolactone use. Choice D is also incorrect as spironolactone does not need to be taken on an empty stomach.
5. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?
- A. INR of 1.1
- B. PT of 12 seconds
- C. INR of 2.5
- D. Platelet count of 150,000
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.
