Nursing Elites

1. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

• A. 10-15 seconds
• B. 30-35 seconds
• C. 20-25 seconds
• D. 0-5 seconds

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.

2. Each statement is true of fat-soluble vitamins, except one. Which is the exception?

• A. Fairly stable to heat, such as during cooking
• B. Contain carbon
• C. Stored in the pancreas
• D. Absorbed in the intestine along with fats and lipids in food

Correct answer: C

Rationale: Fat-soluble vitamins are not stored in the pancreas; they are stored in the liver and fatty tissues. Choice A is correct as fat-soluble vitamins are fairly stable to heat. Choice B is also correct as fat-soluble vitamins contain carbon. Choice D is correct as fat-soluble vitamins are absorbed in the intestine along with fats and lipids in food.

3. After consuming a meal high in fat, the _____ releases _______ to aid in digestion.

• A. stomach, acid
• B. liver, bile
• C. pancreas, bicarbonate
• D. gallbladder, bile

Correct answer: D

Rationale: The gallbladder releases bile into the small intestine to help digest fats. Bile emulsifies fats, breaking them down into smaller droplets for easier digestion. The stomach primarily releases gastric acid, the liver produces bile but stores it in the gallbladder, and the pancreas secretes bicarbonate to neutralize stomach acid in the small intestine. Therefore, choices A, B, and C are incorrect.

4. Patients with kidney stones should increase their intake of:

• A. fluids
• B. vitamin C
• C. oxalates
• D. protein

Correct answer: A

Rationale: Patients with kidney stones should increase their intake of fluids. Increasing fluid intake helps to dilute the urine and reduce the risk of kidney stones forming by flushing out minerals that can crystallize. This promotes the passage of small stones and helps prevent the formation of new ones. Vitamin C and protein intake should be moderated as excessive consumption may lead to the formation of certain types of kidney stones. Oxalates should be limited in the diet as they can contribute to the formation of calcium oxalate stones, a common type of kidney stone.

5. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

• A. glucagon
• B. ghrelin
• C. leptin
• D. insulin

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
