Nursing Elites

1. Katherine is a young Unit Manager of the Pediatric Ward. Most of her staff nurses are senior

• A. Identify the source of the conflict and understand the points of friction
• B. Disregard what she feels and continue to work independently
• C. Seek help from the Director of Nursing
• D. Quit her job and look for another employment.

Correct answer: C

Rationale: The correct answer is C: Seek help from the Director of Nursing. As a young Unit Manager managing a team of senior staff nurses, Katherine may face challenges in leading and gaining the respect of her team due to the age and experience gap. Seeking help from the Director of Nursing can provide her with guidance, mentorship, and support in navigating these challenges. It is important for Katherine to communicate openly about any conflicts or issues she may be facing in order to address them effectively and maintain a positive work environment. Quitting her job (option D) should be considered as a last resort after exhausting all other possible solutions.

2. Which of the following reagents can be used to convert a primary alcohol to an alkyl halide?

• A. HI
• B. H2O
• C. NaOH
• D. SOCl2

Correct answer: D

Rationale: The correct answer is D: SOCl2. SOCl2, also known as thionyl chloride, is commonly used to convert primary alcohols to alkyl halides through an SN2 mechanism. Thionyl chloride reacts with the alcohol to form an alkyl chloride, replacing the hydroxyl group. Option A, HI (hydroiodic acid), is typically used to convert alcohols to alkyl iodides, while option B, H2O (water), and option C, NaOH (sodium hydroxide), are not reagents suitable for this specific transformation. Therefore, SOCl2 is the most appropriate reagent for converting a primary alcohol to an alkyl halide.

3. Express 0.75 as a fraction.

• A. 4/5
• B. 3/4
• C. 1/2
• D. 1/4

Correct answer: B

Rationale: Decimals can be represented as fractions where the denominator is a power of 10 (in this case, 10 raised to the power of -1, or 1/10th). So, 0.75 is equivalent to 7/10. We can simplify this fraction by dividing the numerator and denominator by 5, resulting in 3/4.

4. What is the waxy or oily substance produced by sebaceous glands that helps lubricate the skin and hair?

• A. Keratin
• B. Melanin
• C. Sebum
• D. Sweat

Correct answer: C

Rationale: The correct answer is C: Sebum. Sebum is a waxy or oily substance produced by the sebaceous glands in the skin. It helps lubricate and waterproof the skin and hair, preventing them from drying out. Keratin is a protein found in the skin, hair, and nails, providing structure and strength. Melanin is a pigment that gives color to the skin, hair, and eyes. Sweat is produced by sweat glands and helps regulate body temperature by cooling the skin through evaporation. In this question, sebum specifically refers to the substance produced by sebaceous glands, making it the correct answer.

5. Which type of muscle tissue contracts involuntarily and is found in organs like the heart and intestines?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: Smooth muscle. Smooth muscle tissue contracts involuntarily and is found in organs like the heart and intestines. Skeletal muscle is responsible for voluntary movements, and cardiac muscle is specific to the heart. Therefore, smooth muscle is the only type of muscle tissue that fits the description provided in the question, making it the correct choice. Option D, 'All of the above,' is incorrect as it includes skeletal and cardiac muscles, which do not fit the criteria of being found in organs like the heart and intestines. Understanding the differences between these types of muscle tissue is crucial for comprehending their specific functions in the body.

6. A water fountain has a spherical base (diameter 50cm) and a cylindrical body (diameter 30cm, height 80cm) on top. What is the total surface area of the fountain (excluding the water surface)?

• A. 3142 sq cm
• B. 4712 sq cm
• C. 5486 sq cm
• D. 7957 sq cm

Correct answer: C

Rationale: Calculate the surface area of the sphere and the cylinder separately, then add them up.
