A client is admitted to the medical-surgical unit with a chief complaint of prolonged vomiting over the past 24 hours. Based on the arterial blood gas (ABG) results of pH 7.5. PaCO2 36, HCO3 40, the nurse determines that the client is experiencing:
respiratory alkalosis.
respiratory acidosis.
metabolic acidosis.
metabolic alkalosis.
The Correct Answer is D
D. Metabolic alkalosis is characterized by an increased pH (alkalosis) and an increased HCO3. In this case, the pH is elevated (7.5), indicating alkalosis, which supports metabolic alkalosis. The HCO3 is elevated at 40 mEq/L, which further supports metabolic alkalosis. The PaCO2 is normal or slightly low (36 mmHg), which can occur as a compensatory response to metabolic alkalosis.
A. Respiratory alkalosis is characterized by an increase in pH (alkalosis) and a decrease in PaCO2 (hypocapnia). In this scenario, the pH is elevated (7.5), which indicates alkalosis. The PaCO2 is 36 mmHg, which is within the normal range (35-45 mmHg) but slightly on the lower side (slight hypocapnia). The HCO3 is elevated at 40 mEq/L, which suggests a compensatory response by the kidneys to retain bicarbonate to counteract the alkalosis.
B. Respiratory acidosis is characterized by a decrease in pH (acidosis) and an increase in PaCO2 (hypercapnia). In this case, the pH is elevated (7.5), indicating alkalosis, which contradicts respiratory acidosis. The PaCO2 is 36 mmHg, which is normal or slightly low, not high as expected in respiratory acidosis. The elevated HCO3 (40 mEq/L) suggests a compensatory metabolic response to the alkalosis, not to acidosis.
C. Metabolic acidosis is characterized by a decreased pH (acidosis) and a decreased HCO3. In this scenario, the pH is elevated (7.5), indicating alkalosis, which contradicts metabolic acidosis. The HCO3 is elevated at 40 mEq/L, indicating metabolic alkalosis rather than metabolic acidosis.

Correct Answer is D
Explanation
D. Processed foods, including canned soups, snacks, and pre-packaged meals, are major sources of dietary sodium. By avoiding processed foods, the client can significantly reduce their sodium intake and better adhere to a low-sodium diet.
A. While organic vegetables may be a healthy choice for other reasons (such as reducing pesticide exposure), canned vegetables, whether organic or not, often contain added sodium for preservation. Therefore, selecting canned vegetables, even if organic, may not align with the goal of reducing sodium intake.
B. This statement suggests an understanding of choosing lower-sodium options for sandwiches. Lean deli meats, such as turkey or chicken breast, typically contain less sodium compared to processed or cured meats like salami or bologna. Opting for lean deli meats supports the client's effort to reduce sodium intake as part of a low-sodium diet.
C. This statement indicates a misunderstanding of a low-sodium diet. Smoked meats, such as smoked ham or bacon, are often high in sodium due to the curing and smoking process. Including smoked meat products in the diet would likely increase sodium intake, which contradicts the goal of reducing sodium.
Correct Answer is ["B","C","D"]
Explanation
B. Temperature can significantly affect sleep quality. Ensuring the room is kept at a comfortable temperature (not too hot or cold) can promote better sleep. This intervention is appropriate.
C. Clean and dry bed linens contribute to comfort, which is essential for promoting sleep. This intervention is appropriate.
D. Discomfort can be a major barrier to sleep. Addressing any discomfort, such as pain, anxiety, or positioning issues, can help improve the client's ability to fall and stay asleep. This intervention is appropriate.
A. Offering chocolate, which contains caffeine, close to bedtime is not recommended as caffeine can interfere with sleep. Therefore, this option is not appropriate.
E. Moving the client closer to the nursing station may increase noise and disrupt sleep, especially if there are frequent activities or conversations near the nursing station. Therefore, this option is not typically recommended unless the client requires closer monitoring due to medical reasons.
