1. In a client with asthma who develops respiratory acidosis, 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 serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.

2. Which of the following goals is the most important for the nurse to address for a client admitted to the cardiac rehabilitation unit?

• A. Reduction of anxiety
• B. Referral to community resources
• C. Identification of lifestyle changes
• D. Verbalization of energy-conservation techniques

Correct answer: C

Rationale: The most important goal for a client admitted to the cardiac rehabilitation unit is the identification of lifestyle changes. This is crucial in promoting cardiovascular health and preventing future cardiac issues. Lifestyle changes such as diet modifications, exercise routines, smoking cessation, and stress management play a significant role in improving the overall cardiovascular well-being of the patient. While reducing anxiety, referring to community resources, and verbalizing energy-conservation techniques are all important aspects of care, identifying lifestyle changes is the primary focus in helping the client achieve long-term cardiovascular wellness.

3. When assessing a client with early impairment of oxygen perfusion, such as a pulmonary embolus, the nurse should expect to find restlessness and which of the following symptoms?

• A. cool, clammy skin
• B. bradycardia
• C. tachycardia
• D. eupnea

Correct answer: C

Rationale: When a client has early impairment of oxygen perfusion, such as in a pulmonary embolus, the nurse should expect to find restlessness, diaphoresis, tachycardia, and cool skin. Tachycardia is a compensatory mechanism to increase oxygen delivery to tissues. Cool, clammy skin (choice A) is more indicative of impaired oxygen perfusion compared to warm, dry skin. Bradycardia (choice B) is less likely to occur in the early stages and is more common in severe cases. Eupnea (choice D) refers to normal respirations in rate and depth, which may not be altered in early impairment of oxygen perfusion.

4. What happens if folic acid is administered to treat anemia without determining its underlying cause?

• A. Erythropoiesis is inhibited
• B. Excessive levels of folic acid might accumulate, causing toxicity
• C. The symptoms of pernicious anemia might be masked, delaying treatment
• D. Intrinsic factor is destroyed

Correct answer: C

Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.

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?

• A. Cushingoid appearance
• B. Alopecia
• C. Temporary or permanent sterility
• D. Pathologic fractures

Correct answer: B

Rationale: The correct answer is B: alopecia. Chemotherapy drugs like vincristine and nitrogen mustard commonly cause hair loss (alopecia), which can significantly impact body image. While a Cushingoid appearance can be a side effect of long-term steroid use, it is not typically associated with the chemotherapy regimen mentioned. Temporary or permanent sterility can result from chemotherapy, affecting fertility but not directly contributing to altered body image. Pathologic fractures are not commonly linked to Hodgkin's disease or its treatment, unlike alopecia which is a well-known side effect.
