Which part of the digestive system absorbs most of the vitamins and minerals?
- A. small intestine
- B. large intestine
- C. mouth
- D. esophagus
Correct Answer: A
Rationale: The small intestine is the correct answer because it is the primary site for nutrient absorption, including vitamins and minerals. It has a large surface area thanks to villi and microvilli, facilitating absorption. The large intestine mainly absorbs water and electrolytes, not vitamins and minerals. The mouth and esophagus are not involved in nutrient absorption but rather in the initial stages of digestion and transportation of food.

An important nursing intervention for a patient with a small intestinal obstruction who has an NG tube is to
- A. offer ice chips to suck PRN.
- B. provide mouth care every 1 to 2 hours.
- C. irrigate the tube with normal saline every 8 hours.
- D. keep the patient supine with the head of the bed elevated 30 degrees.
Correct Answer: B
Rationale: The correct answer is B: provide mouth care every 1 to 2 hours. This is crucial to maintain oral hygiene and comfort for the patient with an NG tube to prevent complications like dry mouth and infection. Offering ice chips (choice A) may worsen the obstruction. Irrigating the tube with normal saline (choice C) can disrupt the bowel and is not recommended. Keeping the patient supine with the head of the bed elevated (choice D) is a general measure but not specific to NG tube care.
Mumps is inflammation of the ______ salivary gland caused by a virus.
- A. buccal
- B. sublingual
- C. submandibular
- D. parotid
Correct Answer: D
Rationale: The correct answer is D: parotid. Mumps is inflammation of the parotid salivary gland. The parotid gland is the largest salivary gland located near the ear. It is commonly affected by the mumps virus, causing swelling and pain.
Rationale:
1. The parotid gland is the main salivary gland affected by the mumps virus.
2. The other choices, buccal, sublingual, and submandibular glands, are not typically associated with mumps.
3. Understanding the anatomical location and function of the salivary glands helps in identifying the correct answer.
What does the term 'peristalsis' refer to?
- A. the mixing of digestive juices
- B. the voluntary contraction of muscles
- C. the rhythmic contractions that move food along the digestive tract
- D. the absorption of nutrients
Correct Answer: C
Rationale: Peristalsis refers to the rhythmic contractions that move food along the digestive tract. This process helps propel food from the esophagus to the stomach and through the intestines for digestion and absorption. It is an involuntary movement controlled by the autonomic nervous system. Choice A is incorrect as it refers to digestion, not movement. Choice B is incorrect as peristalsis is involuntary, not voluntary. Choice D is incorrect as peristalsis does not involve absorption but rather transportation of food.
What manifestation in the patient does the nurse recognize as an early sign of hepatic encephalopathy?
- A. Manifests asterixis
- B. Becomes unconscious
- C. Has increasing oliguria
- D. Is irritable and lethargic
Correct Answer: D
Rationale: The correct answer is D: Is irritable and lethargic. Early signs of hepatic encephalopathy often include behavioral changes like irritability and lethargy due to impaired brain function from liver dysfunction. This is because the liver is unable to properly detoxify ammonia, leading to its accumulation in the bloodstream and affecting brain function. Asterixis, unconsciousness, and oliguria are more severe manifestations seen in later stages of hepatic encephalopathy. Therefore, recognizing irritability and lethargy in a patient would prompt early intervention to prevent further progression of hepatic encephalopathy.
A 68-yr-old male patient with a stroke is unconscious and unresponsive to stimuli. After learning
- A. , what should the nurse plan to assess more frequently than is routine?
- B. Apical pulse
- C. Bowel sounds
- D. Breath sounds
Correct Answer: D
Rationale: The correct answer is D: Breath sounds. In an unconscious stroke patient, airway patency and adequate oxygenation are critical. Assessing breath sounds more frequently than routine helps monitor for respiratory distress, such as aspiration or pneumonia. Apical pulse (B) may be important but not as immediately life-threatening as respiratory status. Bowel sounds (C) may indicate bowel function but are not as urgent as assessing breathing. By prioritizing breath sounds, the nurse can ensure timely intervention in case of respiratory compromise.
