A patient with a lung disease takes prophylactic antibiotics and tries to stay indoors during the winter. Today the patient reports bleeding more than normal after a minor injury. How would the nurse evaluate this report?
1. The antibiotic may be interfering with clotting times.
2. The patient is not getting enough vitamin D from sunlight.
3. The patient may be ingesting more vitamin K–containing food.
4. The patient's lung disease has affected the production of platelets.
1
Rationale 1: Some people develop prolonged bleeding times while taking antibiotics.
Rationale 2: Insufficient vitamin D is not the likely reason for this bleeding.
Rationale 3: Vitamin K is an antidote for warfarin and can cause increased clotting, not increased bleeding.
Rationale 4: There is no indication that lung disease reduces platelet production. It may, however, increase erythrocyte production.
