1. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?
- A. Uncompensated respiratory acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic acidosis
- D. Compensated metabolic alkalosis
Correct answer: A
Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.
2. A nurse is required to float to another unit within the hospital where he is asked to care for a client on a ventilator. The nurse is uncomfortable with this assignment, as he has not had a ventilated client since nursing school. What is the nurse's most appropriate response?
- A. Explain to the nursing supervisor the level of discomfort and ask for a different assignment
- B. State that the client's needs are outside the nurse's scope of practice and request a different assignment
- C. Accept the assignment, asking for help when necessary
- D. Request to return to the home unit and send another nurse who can perform the job
Correct answer: A
Rationale: When floating to another unit and asked to take an assignment that falls outside a nurse's comfort zone, the nurse should notify the area supervisor of the level of discomfort and request a different assignment. Caring for ventilated clients typically falls within the scope of nursing practice; however, discomfort with the situation may not necessarily be overcome by accepting the assignment. Alternatively, the effects could be harmful to the client if the nurse is unfamiliar with this type of care. Requesting a different assignment is the most appropriate response in this situation, ensuring patient safety and the nurse's comfort level. Stating that the client's needs are outside the nurse's scope of practice (Choice B) may not be accurate, as caring for ventilated clients usually falls within the scope of nursing practice. Accepting the assignment (Choice C) without addressing the discomfort may compromise patient safety. Requesting to return to the home unit (Choice D) does not address the immediate need of caring for the ventilated client and may delay appropriate care.
3. Which of the following conditions increases a client's risk of aspiration of stomach contents?
- A. A client is in restraints
- B. A client has a scaphoid abdomen
- C. A client is lying prone
- D. More than one answer is correct
Correct answer: A
Rationale: A client in restraints is at an increased risk of aspiration of stomach contents. When a client is restrained, they may be unable to effectively move or turn their body if they begin to vomit, which can lead to aspiration. This lack of mobility can hinder their ability to protect their airway. On the other hand, a scaphoid abdomen, which is sunken or hollowed, is not a direct risk factor for aspiration. Additionally, lying prone, facing downward, does not necessarily increase the risk of aspiration, as aspiration is more likely when lying supine (facing upward). Therefore, the correct answer is that a client is in restraints.
4. Which of the following nursing interventions is appropriate for a client suffering from a fever?
- A. Avoid withholding food from the client
- B. Increase the client's fluid intake
- C. Provide oxygen
- D. All answers are correct
Correct answer: B
Rationale: The appropriate nursing intervention for a client suffering from a fever is to increase the client's fluid intake. A fever can elevate the body's metabolism, leading to increased breathing and heart workload. This can result in fluid loss due to heightened respiration and sweating. Moreover, the augmented heart workload may necessitate more oxygen to maintain tissue perfusion. Providing oxygen and increasing fluid intake help meet the body's heightened demands during a fever. Withholding food from the client is inappropriate as proper nutrition is crucial for recovery, and providing oxygen alone may not address the fluid and metabolic demands associated with fever. Therefore, the correct choice is to increase the client's fluid intake.
5. A nurse is caring for a client who is post-op day #1 after a total hip replacement. Although the client was alert with a normal affect in the morning, by lunchtime, the nurse notes the client is confused, has slurred speech, and is having trouble with her balance. Her blood glucose level is 48 mg/dl. What is the next action of the nurse?
- A. Contact the physician immediately
- B. Administer a bolus of 50 cc of D20W through the IV
- C. Administer 10 units of regular insulin
- D. Give the client 6 oz. of orange juice
Correct answer: D
Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.
