A nurse is caring for a client who has a deep vein thrombosis and a prescription for heparin. For which of the following findings should the nurse withhold the medication and notify the provider?
INR 0.8, aPTT 85 seconds.
INR 2, aPTT 60 seconds.
The Correct Answer is B
Choice A rationale:
An INR (International Normalized Ratio) of 0.8 is within the normal range for someone not on anticoagulation therapy. The aPTT (activated partial thromboplastin time) of 85 seconds is prolonged, but it is not a reason to withhold heparin in itself. Therefore, the nurse should not withhold the medication for these values.
Choice B rationale:
An INR of 2 indicates the client's blood is taking twice as long to clot compared to the average, which can increase the risk of bleeding. The aPTT of 60 seconds is within the normal range. However, the elevated INR suggests the client might be overly anticoagulated, so the nurse should withhold the medication and notify the provider.

Correct Answer is ["A","C","E"]
Explanation
Choice A rationale:
An elevated white blood cell (WBC) count is an expected manifestation in a client with suspected appendicitis. Inflammation in the appendix leads to an immune response, causing an increase in WBC count.
Choice B rationale:
Elevated amylase level is not typically associated with appendicitis. Elevated amylase is more commonly seen in pancreatitis, not appendicitis.
Choice C rationale:
Rebound tenderness, which refers to increased pain when pressure is released rather than applied, is a classic symptom of appendicitis. The nurse should expect to find rebound tenderness during the abdominal assessment.
Choice D rationale:
Ascites are not a common manifestation of appendicitis. Ascites is the accumulation of fluid in the abdominal cavity and are more commonly seen in liver cirrhosis and certain other conditions, but not in appendicitis.
Choice E rationale:
Anorexia, or loss of appetite, can be seen in clients with appendicitis due to the inflammation and discomfort in the abdominal region.
Correct Answer is ["A","D"]
Explanation
Choice A rationale:
Prolonged sun exposure is a risk factor for osteoporosis because it can lead to vitamin D deficiency. Vitamin D is essential for calcium absorption, and low levels of vitamin D can contribute to reduced bone density and increased risk of fractures.
Choice B rationale:
Reduced intake of vitamin E is not a well-established risk factor for osteoporosis. Vitamin E is an antioxidant and plays a role in various bodily processes, but its association with osteoporosis is not supported by strong evidence.
Choice C rationale:
Drinking one glass of wine per day is not a risk factor for osteoporosis. In fact, moderate alcohol consumption has been suggested to have a protective effect on bone density in some studies.
Choice D rationale:
Exposure to second-hand tobacco smoke is a risk factor for osteoporosis. Smoking and exposure to tobacco smoke have been linked to decreased bone density and increased risk of fractures, making this an important point to include in the teaching.
