B. Acts as he does because he expects that his behavior will yield positive results
C. Uses visioning as the core of his leadership
D. Matches his leadership style to the situation at hand.

Correct answer: D

Rationale: The correct answer is D because matching leadership style to the situation at hand is a key aspect of effective leadership. Being able to adapt and adjust leadership approaches based on the specific circumstances and needs of a situation can lead to better outcomes and success. In this scenario, the Chief Nurse Executive's ability to tailor his leadership style to different situations is likely to contribute to his effectiveness in managing various challenges and leading the team effectively.

2. A medication order is for 250 micrograms of a drug to be administered subcutaneously. The available syringe measures in milliliters. How many milliliters should the nurse draw up?

A. 0.00025 milliliters
B. 0.0025 milliliters
C. 0.025 milliliters
D. 0.25 milliliters

Correct answer: B

Rationale: First convert micrograms to milliliters, knowing 1000 micrograms equal 1 milliliter. Divide the desired dosage (250 micrograms) by the conversion factor (1000 micrograms/milliliter) to find the volume needed: 250 micrograms / 1000 micrograms/milliliter = 0.00025 milliliters. However, drawing such a small volume might be inaccurate, so round to the nearest practical measurement, which is 0.0025 milliliters.

3. Which nitrogenous bases pair with each other in DNA?

A. A-G and T-C
B. A-T and C-G
C. -A and T-T
D. C-C and G-G

Correct answer: B

Rationale: Rationale: In DNA, nitrogenous bases pair with each other in a specific manner known as complementary base pairing. Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G). This pairing is essential for maintaining the structure and function of DNA. Therefore, option B is the correct answer as it correctly identifies the nitrogenous bases that pair with each other in DNA.

4. Differentiate between epithelial and connective tissue.

A. Epithelial tissue is exclusively found in the lungs, while connective tissue supports tendons.
B. Both are composed of cells, but epithelial tissue lines surfaces and glands, while connective tissue binds other tissues.
C. Epithelial tissue is more vascularized, while connective tissue is responsible for muscle contraction.
D. Epithelial tissue is the largest tissue type, while connective tissue is the smallest.

Correct answer: B

Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ.

5. Distinguish between the digestive and respiratory systems.

A. Mouth
B. Stomach
C. Small intestine
D. Lungs

Correct answer: D

Rationale: Rationale: - The mouth, stomach, and small intestine are all parts of the digestive system, responsible for breaking down food into nutrients that can be absorbed by the body. - The lungs are part of the respiratory system, responsible for the exchange of oxygen and carbon dioxide between the body and the environment through breathing. - While the digestive system processes food for energy and nutrients, the respiratory system is focused on the exchange of gases necessary for cellular respiration.

6. Which type of nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom?

A. Electromagnetism
B. Gravity
C. Strong nuclear force
D. Weak nuclear force

Correct answer: C

Rationale: The incredibly powerful, strong nuclear force overcomes the repulsive electrostatic force between protons, binding them together and stabilizing the nucleus.
