A nurse is caring for a client who develops a sudden onset of dyspnea. Which of the following findings should the nurse expect if the client has a pulmonary embolus?
Expiratory rhonchi.
Petechiae over the lower extremities.
Hemoptysis.
Flattened neck veins.
The Correct Answer is C
Choice A rationale:
Expiratory rhonchi are typically associated with conditions such as chronic bronchitis or asthma but are not specific to pulmonary embolism.
Choice B rationale:
Petechiae over the lower extremities is not a characteristic finding in pulmonary embolism. Petechiae are tiny red or purple spots that appear due to bleeding under the skin and may be associated with other conditions like thrombocytopenia.
Choice C rationale:
The correct choice. Hemoptysis, which refers to coughing up blood, is a concerning finding in pulmonary embolism. It occurs due to the obstruction of blood flow in the pulmonary vasculature, leading to blood leaking into the lungs.
Choice D rationale:
Flattened neck veins are more likely to be observed in conditions associated with decreased venous return to the heart, such as hypovolemia or cardiac tamponade, and are not directly related to pulmonary embolism.

Correct Answer is B
Explanation
Choice A rationale:
The statement "If I can keep my hemoglobin A1C less than 6.5%, I will be cured of diabetes.”. is incorrect. While maintaining an A1C level below 6.5% is a recommended target for some individuals with diabetes, achieving this level does not cure diabetes. Diabetes is a chronic condition that requires ongoing management and lifestyle modifications.
Choice B rationale:
Checking blood sugar levels before exercising is an important aspect of managing type 1 diabetes. Exercise can affect blood glucose levels, and knowing the current level helps the client determine whether it is safe to engage in physical activity or if adjustments to insulin or carbohydrate intake are needed.
Choice C rationale:
Having regular eye checks every 2 years is essential for clients with diabetes, but it is not the best statement that indicates an understanding of health promotion activities for a new diagnosis of type 1 diabetes mellitus.
Choice D rationale:
Soaking feet daily in warm, soapy water is not a recommended practice for clients with diabetes. It can lead to skin dryness and increase the risk of infection. Instead, clients with diabetes should practice daily foot inspections and keep their feet moisturized to prevent complications related to peripheral neuropathy.
Correct Answer is B
Explanation
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.
