1. The nurse is instructing the client on insulin administration. The client's morning dose of insulin is 10 units of regular and 22 units of NPH. The nurse checks the dose accuracy with the client. The nurse determines that the client has prepared the correct dose when the syringe reads how many units?
- A. 10 units.
- B. 22 units.
- C. 32 units.
- D. 24 units.
Correct answer: C
Rationale: The correct dose would be 32 units, which is the sum of 10 units of regular insulin and 22 units of NPH. It is essential to combine the doses of both types of insulin to ensure the client administers the correct total dose. Choices A and B represent the individual doses of regular and NPH insulin, respectively, not the combined total. Choice D is incorrect as it does not reflect the sum of both insulin doses.
2. The client is preparing a morning dose of insulin, which includes 10 units of regular and 22 units of NPH. The nurse is verifying the client's preparation accuracy. What should the syringe read for the correct dose?
- A. 22 units.
- B. 10 units.
- C. 32 units.
- D. 42 units.
Correct answer: C
Rationale: The correct answer is 32 units. To determine the correct dose, the nurse needs to add the 10 units of regular insulin to the 22 units of NPH, resulting in a total of 32 units. Therefore, the syringe should read 32 units. Choices A, B, and D are incorrect because they do not reflect the accurate total dose required for the morning insulin administration.
3. A client is vomiting. For which acid-base imbalance does the nurse assess the client?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: B
Rationale: In a client who is vomiting, the loss of gastric fluid containing hydrochloric acid can lead to metabolic alkalosis. Metabolic alkalosis is caused by the loss of acids such as hydrochloric acid from the body. Therefore, in this scenario, the nurse should assess the client for metabolic alkalosis. Choices A, C, and D are incorrect because vomiting does not typically lead to metabolic acidosis, respiratory acidosis, or respiratory alkalosis.
4. A client is experiencing diarrhea. For which acid-base disorder should the nurse assess the client?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: A
Rationale: When a client experiences diarrhea, the loss of bicarbonate-rich fluids from the body leads to a decrease in the bicarbonate levels in the blood, resulting in metabolic acidosis. Metabolic alkalosis (choice B) is characterized by an increase in bicarbonate levels, which is not typically associated with diarrhea. Respiratory acidosis (choice C) is caused by retention of carbon dioxide, while respiratory alkalosis (choice D) results from excessive exhalation of carbon dioxide, neither of which are directly related to diarrhea. Therefore, the correct answer is metabolic acidosis (choice A) in the context of diarrhea.
5. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:
- A. Compensated metabolic acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic alkalosis
- D. Uncompensated respiratory acidosis
Correct answer: B
Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.
