1. A healthcare professional is reviewing the medication list of a client scheduled for surgery. Which of the following medications places the client at risk for increased bleeding during surgery?
- A. Warfarin
- B. Acetaminophen
- C. Ibuprofen
- D. Aspirin
Correct answer: D
Rationale: Aspirin is an anticoagulant that inhibits platelet function, increasing the risk of bleeding during surgery. It is important for the healthcare professional to identify this medication, inform the surgical team, and consider withholding it prior to surgery to reduce the risk of excessive bleeding. Warfarin is also an anticoagulant but can be managed by adjusting the dosage or monitoring INR levels. Acetaminophen and ibuprofen are not associated with increased bleeding risk as they do not affect platelet function like aspirin.
2. A healthcare professional is caring for a hospitalized client who has an activated partial thromboplastin time (aPTT) greater than 1.5 times the expected reference range. Which of the following blood products should the healthcare professional prepare to transfuse?
- A. Whole blood
- B. Platelets
- C. Fresh frozen plasma
- D. Packed red blood cells
Correct answer: C
Rationale: Fresh frozen plasma is the correct choice for a client with an elevated aPTT because it contains essential coagulation factors that can help correct coagulopathy and prevent bleeding. It is rich in clotting factors like fibrinogen, factors V and VIII, which are crucial in maintaining proper blood clotting function. Whole blood (Choice A) is not typically used to correct coagulopathy and is more suitable for situations requiring both volume and oxygen-carrying capacity. Platelets (Choice B) are indicated for thrombocytopenia, not for correcting coagulation factors. Packed red blood cells (Choice D) are used to increase oxygen-carrying capacity in cases of anemia, not for correcting coagulopathy.
3. What does it mean when a medication has a half-life?
- A. It only lasts for 30 minutes after the medication is given
- B. How long it takes for half of the dose to be eliminated from the bloodstream
- C. It is the peak of how effective the medicine is
- D. Drug is greatly reduced before it reaches the systemic circulation
Correct answer: B
Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.
4. A client with active pulmonary tuberculosis (TB) is to be started on intravenous rifampin therapy. The client should be informed by the nurse that this medication can cause which of the following adverse effects?
- A. Constipation
- B. Black-colored stools
- C. Staining of teeth
- D. Body secretions turning a red-orange color
Correct answer: D
Rationale: The correct answer is D: Body secretions turning a red-orange color. Rifampin is known to cause body secretions, such as urine, sweat, tears, and sputum, to turn a harmless red-orange color. This is a common and expected side effect of rifampin therapy. Choices A, B, and C are incorrect. Constipation is not a common adverse effect of rifampin. Black-colored stools and staining of teeth are not associated with rifampin therapy. It is important for the nurse to educate the client about the harmless red-orange discoloration that may occur with this medication.
5. Before administering lithium to a client with bipolar disorder who has been taking the medication for 1 year, the nurse should check to see that which of the following tests has been completed?
- A. Thyroid hormone assay
- B. Liver function tests
- C. Erythrocyte sedimentation rate
- D. Brain natriuretic peptide
Correct answer: A
Rationale: The correct answer is to check the thyroid hormone assay. Long-term lithium use can result in thyroid dysfunction, making it crucial to monitor the client's thyroid function regularly to detect any abnormalities early and prevent potential complications. Liver function tests (choice B) are not specifically associated with lithium therapy. Erythrocyte sedimentation rate (choice C) is a nonspecific test for inflammation and not directly related to lithium therapy. Brain natriuretic peptide (choice D) is a test used to diagnose heart failure and is not relevant to monitoring lithium therapy.
