- A. pH = 7.22, PCO2 = 55 mmHg, HCO3 = 30 mEq/L.
- B. pH = 7.28, PCO2 = 45 mmHg, HCO3 = 15 mEq/L.
- C. pH = 7.34, PCO2 = 35 mmHg, HCO3 = 25 mEq/L.
- D. pH = 7.40, PCO2 = 25 mmHg, HCO3 = 30 mEq/L.
Correct Answer: A
Rationale: Respiratory acidosis is indicated by a low pH and elevated PCO2, as seen in option A.

Which is the most reliable method for monitoring fluid balance?
- A. Daily intake and output
- B. Vital signs
- C. Daily weight
- D. Skin turgor
Correct Answer: A
Rationale: Monitoring daily intake and output is the most reliable method for assessing fluid balance in a patient. By accurately measuring the amount of fluids taken in through foods, drinks, and IV fluids, as well as the amount of fluids eliminated through urine, stool, vomit, and other means, healthcare providers can closely track the body's fluid balance. Discrepancies between intake and output can indicate potential issues such as dehydration or fluid overload. This method provides quantitative data that can guide appropriate interventions and treatment adjustments to maintain the patient's fluid balance within normal limits. While vital signs, daily weight, and skin turgor are also important indicators of fluid status, they may not always provide as specific or accurate information as the direct measurement of intake and output.
A male client who is HIV positive is admitted to the hospital with a diagnosis of Pneumocystis carinii pneumonia. His live-in partner has accompanied him. During the history interview, the nurse is aware of feeling a negative attitude about the client's lifestyle, what action is most appropriate?
- A. Share these feelings with the client
- B. Discuss the negative feelings with the
- C. Develop a written interview form charge nurse
- D. Avoid eye contact with the client
Correct Answer: B
Rationale: It is important for the nurse to acknowledge and address any negative feelings or biases that may arise during patient care, especially when caring for a patient with a stigmatized condition like HIV/AIDS. Discussing these negative feelings with a trusted colleague, such as the charge nurse, can help the nurse process and overcome their biases in a safe and non-judgmental environment. By addressing these feelings, the nurse can ensure that they provide compassionate and professional care to the patient and their partner without any personal biases interfering with the care delivery. Sharing these feelings with the client or avoiding eye contact would be inappropriate and counterproductive to establishing trust and providing care. Developing a written interview form would not address the underlying issue of negative attitudes or biases and may not be effective in promoting unbiased care.
The parents of a 4-month-old infant tell the nurse that they are getting a microwave oven and will be able to heat the baby's formula faster. What should the nurse recommend?
- A. Never heat a bottle in a microwave oven.
- B. Heat only 10 ounces or more.
- C. Always leave bottle top uncovered to allow heat to escape.
- D. Shake bottle vigorously for at least 30 seconds after heating.
Correct Answer: A
Rationale: The nurse should recommend never heating a bottle in a microwave oven. Microwaves do not heat liquids evenly, and there is a risk of creating hot spots in the formula, which can burn the baby's mouth and throat. It is safer to heat the formula by placing the bottle in warm water or using a bottle warmer to ensure uniform heating throughout.
A child is diagnosed with Wilms' tumor. During assessment, the nurse in charge expects to detect:
- A. Gross hematuria
- B. Dysuria
- C. Nausea and vomiting
- D. An abdominal mass
Correct Answer: D
Rationale: In a child with Wilms' tumor, the nurse would expect to detect an abdominal mass upon assessment. Wilms' tumor, also known as nephroblastoma, is a type of kidney cancer that commonly presents as a firm, non-tender abdominal mass. This mass may be felt upon palpation of the abdomen. Gross hematuria (A) is not a typical finding associated with Wilms' tumor. Dysuria (B) is the term used to describe painful or difficult urination and is not a characteristic symptom of Wilms' tumor. Nausea and vomiting (C) are also not commonly associated with Wilms' tumor, unless the tumor is causing obstruction or compression of nearby structures in the abdomen.
The nurse knows that Parkinson's disease a progressive neurologic disorder is characterized by:
- A. Bradykinesia
- B. Tremor
- C. Muscle rigidity
- D. All of the above
Correct Answer: D
Rationale: Parkinson's disease is a progressive neurologic disorder that is characterized by a triad of symptoms known as the classic Parkinsonian triad. These symptoms include bradykinesia (slowness of movement), tremor (involuntary shaking), and muscle rigidity (stiffness of the muscles). Therefore, all of the given choices are correct in describing the characteristics of Parkinson's disease.
