Question 1 of 5
Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?
Correct Answer: C
Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding. Pernicious anemia results from vitamin B12 deficiency due to a lack of intrinsic factor, leading to faulty absorption from the gastrointestinal tract. While pernicious anemia can lead to other health issues, bleeding tendencies are not a primary concern. Metastatic liver cancer (choice
A) can cause liver dysfunction leading to decreased synthesis of clotting factors, increasing the risk of bleeding. Gram-negative septicemia (choice
B) can lead to disseminated intravascular coagulation (DI
C) causing excessive bleeding. Iron-deficiency anemia (choice
D) can result in microcytic hypochromic red blood cells, which can impair oxygen transport and lead to tissue hypoxia, but it is not directly associated with a significant potential for bleeding.
Question 2 of 5
A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?
Correct Answer: B
Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis.
Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis.
Choice C ('low') is incorrect as potassium levels rise in this condition.
Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.
Question 3 of 5
Why is starting a low CHO diet a contraindication for a client with renal insufficiency?
Correct Answer: B
Rationale: A client with renal insufficiency should not start a low CHO diet because it could result in an increased renal solute load. Clients with renal or liver disease require protein control in their diet to prevent complications. Proteins used must be of high biologic value, and protein intake is usually weight-based. Protein levels may be adjusted based on the client's clinical condition. A minimum level of carbohydrates is needed in the diet to spare protein. Vitamin and mineral supplements might be needed for clients with liver failure. The dietician plays a crucial role in calculating specific nutrient requirements for these clients and monitoring outcomes in conjunction with the healthcare team.
Choice A is incorrect because simply consuming a minimum amount of carbohydrates does not address the issue of increased renal solute load.
Choice C is incorrect as calcium supplements are not the primary concern when considering a low CHO diet for a client with renal insufficiency.
Choice D is incorrect as the focus should be on the contraindication of a low CHO diet for a client with renal insufficiency rather than just high biologic protein sources.
Question 4 of 5
A client, age 28, was recently diagnosed with Hodgkin's disease. After staging, therapy is planned to include combination radiation therapy and systemic chemotherapy with MOPP"?nitrogen mustard, vincristine (Onconvin), prednisone, and procarbazine. In planning care for this client, the nurse should anticipate which of the following side effects to contribute to a sense of altered body image?
Correct Answer: B
Rationale: The correct answer is B: Alopecia. Chemotherapy drugs like vincristine can cause alopecia, which is hair loss. This side effect can significantly impact a patient's body image. While Cushingoid appearance (
A) can be a side effect of long-term steroid use, temporary or permanent sterility (
C) may affect a patient's future fertility but not necessarily alter body image. Pathologic fractures (
D) are not common side effects of Hodgkin's disease or its treatment and do not directly contribute to a sense of altered body image in the same way as alopecia does.
Question 5 of 5
Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?
Correct Answer: C
Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding compared to the other conditions listed. Pernicious anemia is a condition resulting from vitamin B12 deficiency due to the absence of intrinsic factor, necessary for B12 absorption. While pernicious anemia can lead to neurological issues, it is not directly linked to an increased risk of bleeding. Metastatic liver cancer can cause liver dysfunction leading to coagulopathy, gram-negative septicemia can result in disseminated intravascular coagulation (DI
C), and iron-deficiency anemia can lead to microcytic hypochromic red blood cells, increasing the risk of bleeding.
Therefore, pernicious anemia is the least likely to be associated with an increased potential for bleeding out of the options provided.
