1. You will do nasopharyngeal suctioning on Mr. Abad. Your guide for the length of insertion of the tubing for an adult would be:
- A. tip of the nose to the base of the neck
- B. the distance from the tip of the nose to the middle of the neck
- C. the distance from the tip of the nose to the tip of the ear lobe
- D. eight to ten inches
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
2. Each statement is true of swallowing and processing food, except one. Which is the exception?
- A. The swallowing reflex moves a bolus into the esophagus
- B. A bolus is a mass of food
- C. The bolus is transported to the stomach by osmosis and gravity
- D. The bolus penetrates the diaphragm through the esophageal hiatus
Correct answer: C
Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.
3. Which is NOT a characteristic or function of lipids?
- A. Involved in energy metabolism and storage
- B. Provide insulation and protection
- C. Act as hormones that regulate the body
- D. Are hydrophilic
Correct answer: D
Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.
4. A patient is being cared for by a nurse who has stomatitis following radiation treatment. Which of the following is an appropriate intervention for the nurse to take?
- A. Serve foods without sauces or gravies
- B. Offer mouth rinses with normal saline and water
- C. Serve foods while still at a hot temperature
- D. Instruct the client to drink liquids without a straw
Correct answer: B
Rationale: Offering mouth rinses with normal saline and water is an appropriate intervention for a nurse caring for a patient with stomatitis following radiation treatment. This intervention can help soothe and clean the mouth, promoting comfort and oral hygiene. Choice A is incorrect because serving foods without sauces or gravies does not directly address the client's stomatitis. Choice C is incorrect because serving hot foods can exacerbate discomfort in the client's mouth. Choice D is incorrect because using a straw can help in preventing further irritation in the client's mouth.
5. What is the digestive action of lipase?
- A. It breaks down carbohydrates
- B. It breaks down proteins
- C. It breaks down lipids
- D. It aids in fat digestion
Correct answer: C
Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.
