Extract:
Question 1 of 5
What is appropriate care for a client with neutropenia?
Correct Answer: C
Rationale: When a client has neutropenia, they have low white blood cell levels, which increases the risk of infections due to a weakened immune system. Wearing a mask when out of the room is crucial to reduce the risk of exposure to respiratory infections. Avoiding fresh fruits and vegetables is also necessary as they may contain harmful pathogens. Having a private room helps minimize exposure to pathogens and ensures that visitors are carefully screened for any signs of illness. Routine hand washing is essential to prevent the spread of infections in the healthcare setting, but the most direct measure to protect the client from potential infections is wearing a mask when out of the room.
Question 2 of 5
A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?
Correct Answer: D
Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity.
Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.
Question 3 of 5
High uric acid levels can develop in clients who are receiving chemotherapy. This can be caused by:
Correct Answer: B
Rationale: The correct answer is 'rapid cell catabolism.' During chemotherapy, rapid cell destruction occurs, leading to an increase in uric acid levels as a byproduct of cell breakdown. High uric acid levels are primarily a result of the rapid breakdown of cells during chemotherapy, not due to the kidneys' inability to excrete drug metabolites (
Choice
A). The prophylactic antibiotics given concurrently do not directly cause high uric acid levels (
Choice
C). The altered blood pH from the acidic nature of the drugs (
Choice
D) is not a direct cause of elevated uric acid levels; the main mechanism is the rapid cell catabolism that occurs during chemotherapy.
Question 4 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 5 of 5
A patient has recently been prescribed Zidovudine (Retrovir). The patient has AIDS. Which of the following side effects should the patient specifically watch out for?
Correct Answer: B
Rationale: The correct answer is 'Fever and anemia.' Zidovudine (Retrovir) is known to cause anemia as a side effect due to its impact on the bone marrow. Fever is also a common side effect associated with Zidovudine use.
Therefore, the patient should watch out for these specific side effects.
Choice A (Weakness and SO
B) is incorrect as shortness of breath (SO
B) is not a commonly reported side effect of Zidovudine.
Choice C (Hypertension and SO
B) and
Choice D (Fever and hypertension) are unrelated to the known side effects of Zidovudine, making them incorrect.
