A nurse is teaching self-management to a client who has hepatitis B. Which of the following instructions should the nurse include in the teaching?
- A. Rest frequently throughout the day.
- B. Increase physical activity gradually.
- C. Take medication with meals.
- D. Drink fluids to stay hydrated.
Correct Answer: A
Rationale: The correct answer is A: Rest frequently throughout the day. This is important for a client with hepatitis B to allow the body to heal and conserve energy. Choice B may be harmful as excessive physical activity can strain the liver. Choice C is incorrect as medication for hepatitis B is usually taken on an empty stomach. Choice D is important but not specific to hepatitis B management.

A nurse is caring for a client who the provider suspects might have pernicious anemia. The nurse should expect the provider to prescribe which of the following diagnostic tests?
- A. Schilling test
- B. Complete blood count (CBC)
- C. Vitamin B12 level
- D. Bone marrow biopsy
Correct Answer: A
Rationale: The correct answer is A: Schilling test. Pernicious anemia is caused by vitamin B12 deficiency, often due to poor absorption. The Schilling test is specifically used to diagnose pernicious anemia by evaluating the body's ability to absorb vitamin B12. The test involves giving the patient a small amount of radioactive vitamin B12 to determine how well it is absorbed and utilized by the body. This test helps to differentiate pernicious anemia from other causes of B12 deficiency.
Choice B (Complete blood count) is a general test that may show abnormalities in red blood cells seen in anemia, but it does not specifically diagnose pernicious anemia. Choice C (Vitamin B12 level) alone may not differentiate between pernicious anemia and other causes of B12 deficiency. Choice D (Bone marrow biopsy) is not typically necessary for diagnosing pernicious anemia and is more invasive compared to the Schilling test.
A nurse is reviewing the laboratory findings for a client who developed fat embolism syndrome (FES) following a fracture. Which of the following laboratory findings should the nurse expect?
- A. Decreased serum calcium level
- B. Increased potassium level
- C. Decreased white blood cell count
- D. Increased serum albumin level
Correct Answer: A
Rationale: The correct answer is A: Decreased serum calcium level. In fat embolism syndrome (FES), fat droplets enter the bloodstream and can affect various organs. One of the common complications is hypocalcemia due to the binding of calcium to the fatty acids, leading to decreased serum calcium levels. This can result in symptoms such as confusion, tetany, and seizures. The other choices are incorrect because: B: Increased potassium level is not typically associated with FES. C: Decreased white blood cell count is not a common finding in FES. D: Increased serum albumin level is not related to FES.
A nurse is performing an ECG on a client who is experiencing chest pain. Which of the following statements should the nurse make?
- A. I will need to apply electrodes to your chest and extremities.
- B. You may feel some discomfort during the procedure.
- C. The procedure will take about an hour.
- D. We need to monitor your heart rate continuously after the procedure.
Correct Answer: A
Rationale: Correct Answer: A
Rationale: Applying electrodes to the chest and extremities is necessary for a complete ECG recording. Electrodes are placed strategically to capture electrical activity of the heart. This statement informs the client about the procedure and ensures accurate results. Other options are incorrect because discomfort during the procedure is subjective and not guaranteed (B), an ECG typically takes only a few minutes, not an hour (C), and continuous heart rate monitoring is not required post-procedure unless indicated by the results (D).
A nurse is monitoring a client who was admitted with a severe burn injury and is receiving IV fluid resuscitation therapy. The nurse should identify a decrease in which of the following findings as an indication of adequate fluid replacement?
- A. Blood pressure
- B. Heart rate
- C. Urine output
- D. Respiratory rate
Correct Answer: B
Rationale: The correct answer is B: Heart rate. A decrease in heart rate indicates adequate fluid replacement in a burn-injured patient due to improved cardiac output and perfusion. When fluid resuscitation is effective, the heart doesn't need to work as hard to maintain circulation. Blood pressure (choice A) may fluctuate initially but is not a reliable indicator of fluid replacement alone. Urine output (choice C) is important but may take time to stabilize. Respiratory rate (choice D) may be affected by pain or stress, not solely fluid status. Other choices are not relevant.
A nurse is assessing a client for hypoxemia during an asthma attack. Which of the following manifestations should the nurse expect?
- A. Cyanosis
- B. Agitation
- C. Hypotension
- D. Dizziness
Correct Answer: B
Rationale: The correct answer is B: Agitation. During an asthma attack, hypoxemia can lead to decreased oxygen supply to the brain, causing agitation due to hypoxia. Cyanosis (A) is a bluish discoloration of the skin and mucous membranes, indicating severe hypoxemia. Hypotension (C) is not typically associated with hypoxemia in asthma. Dizziness (D) is more commonly seen in conditions like hyperventilation rather than hypoxemia. In summary, agitation is the most likely manifestation of hypoxemia during an asthma attack due to decreased oxygen supply to the brain.
