1. A client is on intravenous heparin to treat a pulmonary embolism. The client's most recent partial thromboplastin time (PTT) was 25 seconds. What action should the nurse anticipate?
- A. Decrease the heparin rate.
- B. Increase the heparin rate.
- C. No change to the heparin rate.
- D. Stop the heparin; start warfarin (Coumadin).
Correct answer: B
Rationale: For clients on heparin therapy, a PTT value of 1.5 to 2.5 times the normal range is required to ensure therapeutic anticoagulation. The normal PTT range is 25 to 35 seconds. In this case, the client's PTT of 25 seconds falls below the therapeutic range, indicating that the heparin dose is insufficient. Therefore, the nurse should anticipate increasing the heparin rate to achieve the desired therapeutic effect.
2. A healthcare professional is caring for a client who has just developed a pulmonary embolism. Which of the following medications should the healthcare professional anticipate administering?
- A. Furosemide
- B. Dexamethasone
- C. Heparin
- D. Atropine
Correct answer: C
Rationale: In the scenario of a pulmonary embolism, the priority medication to administer is Heparin. Heparin is an anticoagulant that helps prevent the formation of new blood clots and the growth of existing ones, which is crucial in managing pulmonary embolism. Furosemide is a diuretic used to treat fluid retention, Dexamethasone is a corticosteroid used for inflammation, and Atropine is an anticholinergic medication used for various purposes such as treating bradycardia.
3. Prior to performing percussion, vibration, and postural drainage on an adolescent client with pneumonia, which of the following nursing actions should the nurse complete first?
- A. Auscultate lung fields
- B. Assess pulse and respirations
- C. Assess characteristics of the sputum
- D. Instruct the client to slowly exhale with pursed lips
Correct answer: A
Rationale: Before initiating percussion, vibration, and postural drainage, the nurse should first auscultate the lung fields to assess the baseline lung sounds and identify areas of congestion or abnormality. This initial assessment helps the nurse to tailor the percussion and drainage techniques effectively. Assessing pulse and respirations, sputum characteristics, and providing instructions to the client for exhalation are important steps in the procedure but should follow the initial auscultation to ensure a comprehensive and individualized care approach.
4. When reviewing the provider's orders, a nurse recognizes that clarification is needed for which of the following medications in a client experiencing an exacerbation of asthma?
- A. Propranolol
- B. Theophylline
- C. Montelukast
- D. Prednisone
Correct answer: A
Rationale: The correct answer is Propranolol. Propranolol is a beta-blocker that can potentially exacerbate asthma symptoms due to its mechanism of action. It can cause bronchoconstriction, which is harmful for a client experiencing an asthma exacerbation. Theophylline, Montelukast, and Prednisone are commonly used in the treatment of asthma exacerbations and would not typically require clarification in this context.
5. A healthcare professional is caring for four clients on intravenous heparin therapy. Which lab value possibly indicates a serious side effect has occurred?
- A. Hemoglobin: 14.2 g/dL
- B. Platelet count: 82,000/µL
- C. RBC count: 4.8 x 10^6/µL
- D. WBC count: 8.7 x 10^3/µL
Correct answer: B
Rationale: A low platelet count, as seen in choice B, is concerning as it could indicate heparin-induced thrombocytopenia, a serious side effect of heparin therapy. Heparin-induced thrombocytopenia can lead to an increased risk of blood clotting, potentially causing severe complications. Monitoring platelet counts is crucial during heparin therapy to promptly identify and manage this adverse effect.
