A nurse is teaching a client who has a prescription of a nasogastric tube (NG) to treat a pyloric obstruction. Which of the following rationales for the use of the nasogastric tube should the nurse include in the teaching?
Administer medications
Supply nutrients via tube feedings
Decompress the stomach
D. Determine the pH of the gastric secretions
The Correct Answer is C
A. Administer medications:
While nasogastric tubes can be used to administer medications, this is not the primary rationale for their use in pyloric obstruction. The primary goal is often decompression.
B. Supply nutrients via tube feedings:
Providing nutrients via tube feedings is not the primary purpose in the context of a pyloric obstruction. Decompression is more relevant in this scenario.
C. Decompress the stomach:
Decompressing the stomach is a common use of nasogastric tubes in the context of pyloric obstruction. The tube helps to remove excess air and gastric contents, relieving pressure in the stomach.
D. Determine the pH of the gastric secretions:
While determining the pH of gastric secretions is a possible use, it is not the primary rationale for nasogastric tube placement in pyloric obstruction. The primary goal is often to relieve obstruction and decompress the stomach.

Correct Answer is D
Explanation
A. Avoiding eating at fast food restaurants is not a specific preventive measure for hepatitis A transmission. The primary mode of transmission for hepatitis A is through the fecal-oral route, often due to contaminated food or water.
B. Avoiding serving raw foods is a reasonable precaution as raw or undercooked shellfish and contaminated fruits and vegetables can be a source of hepatitis A transmission. However, practicing effective hand hygiene is a more general and fundamental preventive measure.
C. Wearing barrier protection during vaginal intercourse is not directly related to the prevention of hepatitis A. Hepatitis A is primarily transmitted through the fecal-oral route, and sexual transmission is not a common mode for this virus.
D. Practicing effective hand hygiene is a key strategy for preventing the transmission of hepatitis A. Proper handwashing with soap and water, especially after using the bathroom and before handling food, can help reduce the risk of contamination and transmission of the virus.
Correct Answer is B
Explanation
A. Lactulose is not used to decrease potassium levels. It is a laxative that works by drawing water into the colon, softening stools and promoting bowel movements.
B. Lactulose is used to decrease ammonia levels in clients with cirrhosis. Ammonia is a byproduct of protein metabolism, and when the liver is compromised, it may not effectively convert ammonia into urea, leading to elevated ammonia levels in the bloodstream. Lactulose helps reduce ammonia absorption in the colon.
C. Lactulose does not decrease glucose levels significantly. It is not primarily used as an antidiabetic medication.
D. Lactulose does not affect bicarbonate levels significantly. It primarily targets ammonia reduction in clients with cirrhosis.
