In a patient with ARDS, what position improves ventilation?

Supine

Prone

Trendelenburg

Sim's

Answer and Explanation

The Correct Answer is B

A. Supine:
Lying flat can worsen ventilation/perfusion mismatch in ARDS, especially in dependent lung regions.

B. Prone:
Prone positioning improves oxygenation by promoting more even alveolar recruitment and reducing lung compression, enhancing gas exchange in ARDS.

C. Trendelenburg:
This position (head down) increases risk of aspiration and is not helpful in improving oxygenation in ARDS.

D. Sim’s:
This is a recovery position, useful in unconscious patients to prevent aspiration, but not indicated for ARDS.

Correct Answer is B

Explanation

A. Increase the frequency of vital signs monitoring to detect SIRS-related changes:
This is important for systemic assessment but does not directly protect the kidneys from further injury.

B. Carefully monitor and document the patient's serum drug levels to avoid toxicity:
The kidneys excrete many medications. In AKI, impaired clearance increases the risk of drug accumulation and toxicity, making drug level monitoring critical.

C. Administer nephrotoxic medications early in the day to facilitate drug clearance:
Timing does not reduce nephrotoxicity. The type and dosage of drug, along with renal function, are more important considerations.

D. Prioritize nutritional support:
While essential for healing, nutrition does not directly prevent nephrotoxicity. Renal-safe feeding is needed, but drug monitoring is the priority for kidney protection.

A. Bradypnea B. Hypertension C. Oliguria D. Flushing of the skin

Correct Answer is C

Explanation

A. Bradypnea:
Hypovolemic shock often causes tachypnea, not bradypnea, as the body attempts to compensate for metabolic acidosis and hypoxia.

B. Hypertension:
Hypovolemic shock leads to hypotension due to loss of circulating volume.

C. Oliguria:
Decreased renal perfusion leads to reduced urine output, making oliguria an expected finding in hypovolemic shock.

D. Flushing of the skin:
The skin is usually pale, cool, and clammy in hypovolemic shock due to vasoconstriction, not flushed.
