Nokea
A nurse is caring for a client who is scheduled for an outpatient surgical procedure and reports taking aspirin 81 mg daily, including this morning. The nurse should identify that this places the client at risk for which of the following complications?
- A. Uncontrolled bleeding
- B. Myocardial infarction
- C. Respiratory depression
- D. Decreased renal perfusion
Correct Answer: A
Rationale: The correct answer is A: Uncontrolled bleeding. Aspirin is an antiplatelet medication that inhibits platelet aggregation, leading to decreased clotting ability. This places the client at risk for uncontrolled bleeding during and after surgery. Myocardial infarction (B) is not directly associated with aspirin use. Respiratory depression (C) is not a common complication of aspirin. Decreased renal perfusion (D) is not a typical complication of aspirin use.

A leukemia investigator plans to obtain bone marrow under general anesthesia to measure minimal residual disease (MRD) and to see if this time point can predict early relapse. The specimen will be obtained at a time point when otherwise no bone marrow would be sampled. The results are not shared with the treating oncologist, and no therapeutic interventions are decided or based on the results. Which of the following statements is most accurate about this intervention?
- A. It constitutes a minimal-risk procedure because bone marrow assessments are considered routine for patients diagnosed with acute lymphoblastic leukemia.
- B. It constitutes a minimal-risk procedure because it is a single additional procedure being performed during the course of treatment.
- C. It constitutes a greater than minimal-risk procedure because it is being done under general anesthesia.
- D. It is justifiable because future patients may benefit from knowledge gained by the research.
Correct Answer: C
Rationale: The correct answer is C because obtaining bone marrow under general anesthesia carries inherent risks that make it greater than minimal-risk. Here's a step-by-step rationale:
1. General anesthesia poses risks such as allergic reactions, breathing problems, and potential complications, making the procedure more than minimal-risk.
2. Even though bone marrow assessments are routine for leukemia patients, the use of general anesthesia elevates the risk level.
3. The fact that the results are not shared with the treating oncologist and no therapeutic interventions are based on them indicates that the procedure is solely for research purposes, emphasizing the risk-benefit analysis.
4. Choice A is incorrect because the use of general anesthesia increases the procedure's risk level beyond routine.
5. Choice B is incorrect as the focus should be on the inherent risks of general anesthesia, not just the number of procedures performed.
6. Choice D is irrelevant to the risk assessment of the specific procedure and does not address the immediate safety concerns associated with general anesthesia.
Thrombocytopenia is absent in:
- A. DIC
- B. Wiskott Aldrich syndrome
- C. Henoch Schonlein purpura
- D. myelosclerosis
Correct Answer: C
Rationale: Thrombocytopenia is absent in Henoch Schonlein purpura because it is primarily a vasculitis affecting small blood vessels, not directly causing platelet destruction. Thrombocytopenia is present in DIC due to widespread coagulation activation. Wiskott Aldrich syndrome and myelosclerosis both involve platelet dysfunction or decreased production, leading to thrombocytopenia.
A nurse is caring for a client who has hemophilia A and is about to begin taking desmopressin to prevent bleeding. The nurse should monitor the client for which of the following adverse reactions?
- A. Weight loss
- B. Edema
- C. Polyuria
- D. Bradycardia
Correct Answer: B
Rationale: The correct answer is B: Edema. Desmopressin is a synthetic form of vasopressin that can cause fluid retention, leading to edema. This is a common adverse reaction associated with desmopressin use. Weight loss (choice A) is not a typical adverse reaction of desmopressin. Polyuria (choice C) is actually a desired effect of desmopressin, as it helps to concentrate urine. Bradycardia (choice D) is not directly associated with desmopressin use. Monitoring for edema is important to ensure the client's safety and adjust treatment as needed.
The nurse is reviewing the activated partial thromboplastin time for a patient receiving heparin. Which value indicates that the medication is within the therapeutic range?
- A. 2.5 to 9.5 minutes
- B. 9.5 to 11.3 seconds
- C. 1.5 to 2.0 times normal
- D. 2.0 to 3.0 times normal
Correct Answer: C
Rationale: The correct answer is C (1.5 to 2.0 times normal) because the therapeutic range for heparin therapy is typically considered to be 1.5 to 2.0 times the normal control value for activated partial thromboplastin time (aPTT). This range ensures adequate anticoagulation to prevent clot formation without increasing the risk of bleeding. Options A, B, and D are incorrect because they provide ranges that are either too short or too long for the therapeutic goal of heparin therapy. Option A (2.5 to 9.5 minutes) and Option D (2.0 to 3.0 times normal) are outside the typical therapeutic range for heparin, indicating subtherapeutic and supratherapeutic levels, respectively. Option B (9.5 to 11.3 seconds) is also incorrect as it reflects a range for prothrombin time (PT) rather than aPTT.
The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
- A. Do you take salicylates?
- B. Are you taking any oral contraceptives?
- C. Have you been prescribed antiseizure drugs?
- D. How long have you taken antihypertensive drugs?
Correct Answer: A
Rationale: The correct answer is A: Do you take salicylates? Petechiae can be a sign of salicylate use, which can cause bleeding disorders. By asking about salicylates, the nurse can determine if the petechiae are related to medication. Choice B is not directly related to petechiae. Choice C is more specific to antiseizure drugs and not commonly associated with petechiae. Choice D is unrelated to petechiae and focuses on hypertension management. Asking about salicylates is the most appropriate to assess potential medication-induced petechiae.
