What is the best question to evaluate a client’s understanding of infection control measures while receiving treatment for hepatitis A?
Do you eat raw shellfish?.
How do you cook pork products?.
How often do you travel out of the country?.
Do you wash your hands after using the toilet?.
The Correct Answer is D
This question evaluates the client’s understanding of the most important infection control measure for hepatitis A, which is hand hygiene. Hepatitis A is transmitted through ingestion of contaminated food and water or through direct contact with an infectious person’s feces.
Washing hands after using the toilet can prevent the spread of the virus to others and to oneself.
Choice A is wrong because eating raw shellfish is not a risk factor for hepatitis A unless the shellfish is contaminated with the virus from polluted water.
Choice B is wrong because cooking pork products does not affect hepatitis A transmission, as the virus is not found in pork or other meats.
Choice C is wrong because traveling out of the country is not a risk factor for hepatitis A unless the destination has poor sanitation and hygiene conditions.

Correct Answer is C
Explanation
This is because it shows a normal pH, pCO2, HCO3 and pO2, indicating that the treatment has been effective in restoring normal gas exchange and acid- base balance.
Choice A is wrong because it shows a low pH, high pCO2 and high HCO3, indicating a mixed respiratory and metabolic acidosis.
Choice B is wrong because it shows a low pH, high pCO2 and low HCO3, indicating a combined respiratory and metabolic acidosis.
Choice D is wrong because it shows a high pH, low pCO2 and low HCO3, indicating a mixed respiratory and metabolic alkalosis.
The normal ranges for arterial blood gas (ABG) are:
- pH: 7.35 – 7.45
- pO2: 10 – 14 kPa or 75 – 105 mmHg
- pCO2: 4.5 – 6 kPa or 34 – 45 mmHg
Correct Answer is C
Explanation
Just prior to the next scheduled dose. A trough level is the lowest concentration of a drug in the blood, and it is measured just before the next dose is due to be administered.
This helps to ensure that the drug level does not fall below the therapeutic range or rise above the toxic range.
Choice A is wrong because every morning at 08:00 AM (0800) is not a consistent time interval for a drug that is administered every twenty-four hours.
The trough level should be measured at the same time before each dose.
Choice B is wrong because halfway between next scheduled dose is not a trough level, but a midpoint level.
This does not reflect the lowest concentration of the drug in the blood.
Choice D is wrong because two hours after a scheduled dose is not a trough level, but a peak level. This is the highest concentration of the drug in the blood, and it is measured after the drug has been absorbed and distributed. Peak levels are no longer routinely recommended for vancomycin.
