Arterial blood gas levels are obtained for the client. If the client’s results are pH 7.48, CO2 42 mm Hg, and HCO3 32 mEq/L, the client is exhibiting which one of the following acid-base imbalances?
Selected Answer:
D.
Metabolic alkalosis
Correct Answer:
D.
Metabolic alkalosis
Response Feedback:The client’s pH is elevated at 7.48 (normal 7.35 to 7.45), the CO2 is normal at 42 mm Hg (normal 35 to 45 mm Hg), and the bicarbonate is elevated at 32 mEq/L (normal 22 to 26 mEq/L). The client is experiencing metabolic alkalosis. In metabolic acidosis the client’s pH would be below 7.35, and the bicarbonate would be below 22 mEq/L. In respiratory acidosis the client’s pH would be below 7.35, and the CO2 would be elevated above 45 mm Hg. In respiratory alkalosis the client’s pH would be above 7.45, and the CO2 would be below 35 mm Hg.Cognitive Level: analysisNCLEX Blueprint: Physiological

•Question 2
The nurse would suspect that a client who frequently uses which medication is at risk for developing metabolic alkalosis?
Selected Answer:
A.
Calcium carbonate (Tums)
Correct Answer:
A.
Calcium carbonate (Tums)
Response Feedback:Excessive use of oral antacids can lead to metabolic alkalosis . Use of ibuprofen and Tylenol is not associated with the development of metabolic alkalosis. Overdoses of aspirin can be associated with the development of respiratory alkalosis, and eventually can lead to metabolic acidosis.

•Question 3
The nurse records a patient’s hourly urine output from an indwelling catheter as follows:0700: 36 mL0800: 45 mL0900: 85 mL1000: 62 mL1100: 50 mL1200: 48 mL1300:
94 mL1400: 78 mL1500: 60 mLThe nurse can conclude that the patient’s urine output should be described as which of the following? Selected Answer:
B.
Within normal limits
Correct Answer:
B.
Within normal limits
Response Feedback:Urine accounts for the greatest amount of fluid loss. Normal urine output for
an average-sized adult is approximately 1,500 mL in 24 hr. Urine output varies according to intake and activity but should remain at least 30 to 50 mL per hour. The patient’s urine output is within the normal range. This patient has an indwelling catheter, which will result in continual flow of urine.Cognitive level: analysisNCLEX Blueprint: basic care and comfort
•Question 4
A client is admitted with severe diarrhea. Arterial blood gas (ABG) results are pH 7.33; PaCO 2 42; HCO 3 – 20. The nurse concludes this client has which acid–base imbalance?
Selected Answer:
A.
Uncompensated metabolic acidosis
Correct Answer:
A.
Uncompensated metabolic acidosis
Response Feedback:The pH and HCO3– are decreased, indicating metabolic acidosis. The PaCO2 is normal, indicating that compensatory mechanisms have not started working. Compensated or uncompensated respiratory acidosis is incorrect because the primary disturbance is metabolic, as indicated by the low bicarbonate level. Compensated metabolic acidosis is incorrect because
with compensation, a decrease in PaCO2 to restore balance would be expected. Cognitive Level: AnalyzingNCLEX Blueprint: Physiological Adaptation
•Question 5
Identify the appropriate intervention(s) for a patient with hypovolemia. Choose all that apply.
B.
Monitor I&O daily.
C.
Encourage fluid intake.
D.
Monitor electrolyte balance.
Correct Answers: B. Response Feedback:Monitor I&O daily.
C.
Encourage fluid intake.
D.
Monitor electrolyte balance.
Hypovolemia occurs when more fluid is lost than is taken into the body. Monitoring I&O provides information to evaluate the status of the problem.
Encouraging fluid intake helps to correct the problem. It is good to monitor electrolytes because electrolyte imbalance can occur with hypovolemia (although it may not occur at first). Deep-breathing techniques do not address fluid balance; there is no evidence that the patient has a respiratory disorder.Cognitive level: ApplicationNCLEX Blueprint: physiological adaptation
•Question 6
While caring for a patient preparing for a kidney transplant, the nurse knows that the patient
understands teaching on immunosuppression when she states which of the following?
Selected
Answer:
Correct Answer:
Response Feedback:
C.
"The medications that I take will help prevent my body from attacking
my new kidney."
C.
"The medications that I take will help prevent my body from attacking
my new kidney."
Immunosuppressant therapy is initiated to inhibit optimal immune response.
This is necessary in the case of transplantation, because the normal immune
response would cause the body to recognize the new tissue as foreign and attack it. The body will identify the new kidney as foreign and will not treat
it as the original kidney. While patients with transplants must be careful about exposure to others, especially those who are or might be ill, and practice adequate and consistent infection control techniques, they don't have to avoid people or social interaction. The new kidney brings foreign cells regardless of relationship between donor and recipient.Cognitive Level: ApplicationNCLEX Blueprint: Health promotion and Maintenance
