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. While caring for a client who has just come from surgery and is in the recovery room with an endotracheal tube in place, the nurse deflates the cuff on the tube and removes it. The client sits up in bed, grasps his throat, and begins to make wheezing sounds. Which of the following conditions is the most likely cause of this situation?

• A. The client is choking on part of the tube
• B. The client has anxiety
• C. The client is having a laryngospasm
• D. The client is having a normal response from anesthesia

Correct answer: D

Rationale: After surgery, some clients may experience a laryngospasm during emergence from anesthesia. A laryngospasm can lead to the closure of the laryngeal opening due to spasm of the vocal cords. In this scenario, the client's symptoms of wheezing and throat grasping are indicative of a laryngospasm rather than choking on the tube, anxiety, or a normal response from anesthesia. The nurse should act promptly to open the airway to aid breathing and consider administering muscle relaxants as necessary.

3. A client with a new prescription for lithium carbonate for bipolar disorder is being educated by a nurse on early indications of toxicity. The nurse should include which of the following manifestations in the teachings?

• A. Constipation
• B. Polyuria
• C. Rash
• D. Tinnitus

Correct answer: B

Rationale: Polyuria is a crucial early indication of lithium toxicity. It results from the drug's effect on the kidneys, leading to increased urine output. This is a significant symptom to monitor as it can indicate potential toxicity. Constipation, rash, and tinnitus are not typically associated with early indications of lithium toxicity. Constipation is more commonly seen as a side effect of some medications, while rash and tinnitus are not specific indicators of lithium toxicity.

4. 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.

5. A client is preparing to give a stool sample for occult blood. All of the following information is part of teaching for this client EXCEPT:

• A. Avoid eating red meat for 3 days before the test
• B. Collect the stool sample from the toilet after having a bowel movement
• C. The stool does not need to be kept in a container with preservative
• D. A small part of the stool from two areas will be tested using a smear

Correct answer: B

Rationale: When preparing to give a stool sample for occult blood testing, clients need specific instructions to ensure accurate results. It is crucial to educate clients to avoid eating red meat for at least 3 days before the test, as the blood in the meat can interfere with the test results. Clients should be informed that the stool does not need to be kept in a container with preservative as it is not required for this type of testing. Additionally, clients should be aware that a small part of the stool from two areas will be tested using a smear. However, collecting the stool sample from the toilet after having a bowel movement is not recommended as it may introduce contaminants and affect the accuracy of the test. Therefore, this information is not part of the correct teaching for the client preparing to give a stool sample for occult blood.
