Nursing Elites

1. You have been given a sample tissue that has pillar-shaped cells arranged tightly together. The tissue you have is:

• A. Squamous Epithelium
• B. Cuboidal Epithelium
• C. Columnar Epithelium
• D. Transitional Epithelium

Correct answer: C

Rationale: The correct answer is C: Columnar Epithelium. Columnar epithelium is characterized by tall, pillar-like cells that are closely packed together. This arrangement allows for absorption and secretion in tissues like the digestive tract, where this type of epithelium is commonly found. Squamous epithelium (choice A) consists of flat cells, cuboidal epithelium (choice B) has cube-shaped cells, and transitional epithelium (choice D) is found in areas that need to stretch and expand, like the urinary bladder.

2. Which phrase should be moved to improve sentence clarity? 'He opened the door slowly, trying not to wake the baby.'

• A. 'Trying not to wake the baby,' he slowly opened the door
• B. 'He opened the door,' trying not to wake the baby
• C. 'He opened the door slowly,' trying not to wake the baby
• D. 'Slowly trying not to wake the baby,' he opened the door

Correct answer: A

Rationale: Placing 'trying not to wake the baby' at the beginning as in option A clarifies the purpose of the action right away, improving the sentence's flow.

3. Which word in the sentence needs to be corrected for proper grammar?

• A. About it
• B. A
• C. With
• D. Made

Correct answer: B

Rationale: The word 'A' should be corrected to 'an' in the sentence. The sentence should read, 'The nurse made an error with the medication, so the doctor made notes about it in the patient's file.' The article 'an' is used before a noun beginning with a vowel sound, like 'error' in this case. Choices A, C, and D are grammatically correct in the sentence and do not need to be altered.

4. What is the function of the gallbladder?

• A. To produce bile
• B. To store and concentrate bile
• C. To detoxify harmful substances
• D. To break down fats

Correct answer: B

Rationale: The correct answer is B: To store and concentrate bile. The gallbladder's primary function is to store and concentrate bile, which is produced by the liver. Bile is released into the small intestine to aid in the digestion and absorption of fats. It helps in emulsifying fats and facilitating their breakdown by enzymes for better absorption. Choices A, C, and D are incorrect because the gallbladder does not produce bile (it is produced by the liver), detoxify harmful substances, or directly break down fats. Its main role is to store and concentrate bile before releasing it into the small intestine.

5. Select the meaning of the underlined word in the following sentence. At this point, we are providing mainly palliative care.

• A. Scientific
• B. Surgical
• C. Soothing
• D. Serious

Correct answer: C

Rationale: In the context of the sentence, 'palliative care' refers to care that is focused on providing relief from the symptoms and stress of a serious illness. It is not aimed at curing the illness but rather at providing comfort and improving quality of life. Therefore, the meaning of 'palliative' in this context is to soothe or alleviate suffering, making 'soothing' the correct choice. The other options, 'scientific,' 'surgical,' and 'serious,' do not capture the essence of palliative care, which is centered around providing comfort and relief rather than focusing on scientific or surgical interventions or emphasizing seriousness.
