1. Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?

• A. metastatic liver cancer
• B. gram-negative septicemia
• C. pernicious anemia
• D. iron-deficiency anemia

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 (DIC) 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.

2. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

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.

3. When discussing the child's wishes for future care, it is important for the nurse to first identify what the child knows about the disease and his prognosis. Factors such as the perceived severity of the illness will be significant in planning for end-of-life care. If the child does not understand the disease process or prognosis, the plan of care would not be effective or realistic. In addition, asking a child about desired interventions in the event of cardiac or respiratory arrest would not be an appropriate initial area of questioning. If the child does not understand the disease process, these questions may seem frightening or threatening. While exploring the child's belief about death would be important, it would not be the initial area of discussion and should be guided by the child rather than the nurse.

• A. What the child knows about the disease and his prognosis.
• B. How the child would like to handle the plan of care.
• C. What interventions the child would like in the event of cardiac or respiratory arrest.
• D. What the child believes about death.

Correct answer: A

Rationale: When discussing the child's wishes for future care, it is essential to first determine what the child understands about the disease and his prognosis. This information is crucial for planning appropriate end-of-life care. If the child lacks comprehension of the illness and its prognosis, any care plan discussed would be ineffective and unrealistic. Inquiring about desired interventions during cardiac or respiratory arrest is not the initial step, as it may cause distress if the child lacks understanding. While exploring the child's beliefs about death is significant, it should not be the primary focus initially and should be approached based on the child's readiness, not the nurse's agenda. Therefore, the correct first step is to assess what the child knows about the disease and his prognosis.

4. Teaching about the importance of avoiding foods high in potassium is most crucial for which client?

• A. a client receiving diuretic therapy
• B. a client with an ileostomy
• C. a client with metabolic alkalosis
• D. a client with renal disease

Correct answer: D

Rationale: Clients with renal disease are prone to hyperkalemia due to impaired kidney function, making it crucial for them to avoid foods high in potassium to prevent further complications. Choices A, B, and C are incorrect because clients receiving diuretic therapy, with an ileostomy, or with metabolic alkalosis are at risk of hypokalemia. These individuals should actually consume foods high in potassium to replenish the electrolyte lost through diuresis, ileostomy output, or metabolic alkalosis.

5. The nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?

• A. Hypocalcemia.
• B. Hyponatremia.
• C. Hyperkalemia.
• D. Hypophosphatemia.

Correct answer: A.

Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.
