1. Identify the spectator ions in the reaction: 2KCl + Pb(NO3)2 → 2KNO3 + PbCl2.

• A. K+ and NO3-
• B. K+ and Cl-
• C. Pb2+ and NO3-
• D. Pb2+ and Cl-

Correct answer: B

Rationale: Rationale: - In the reaction, potassium ions (K+) and chloride ions (Cl-) are present on both sides of the equation. They are not involved in the formation of the products and remain unchanged. - Lead ions (Pb2+) and nitrate ions (NO3-) are involved in the formation of the products potassium nitrate (KNO3) and lead(II) chloride (PbCl2). - Therefore, the spectator ions in this reaction are K+ and Cl-.

2. Epithelial tissue, which covers surfaces, is further classified based on the number of cell layers. Simple epithelium has:

• A. No layers
• B. One layer
• C. Two to several layers
• D. Many tightly packed layers

Correct answer: B

Rationale: The correct answer is B: 'One layer.' Simple epithelium is characterized by having a single layer of cells. This type of epithelial tissue is found in areas where diffusion, filtration, or absorption are primary functions. Simple epithelium allows for efficient exchange of substances across the cell layer due to its thin structure and close proximity to underlying tissues. Examples of locations where simple epithelium is found include the lining of blood vessels (endothelium) and air sacs of the lungs (alveoli). In contrast, stratified epithelium consists of multiple layers of cells and is commonly found in areas that require protection against mechanical or chemical stress, such as the skin and the lining of the esophagus.

3. You need to paint a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m. Considering only the interior walls and floor (not the top), how much paint do you need (assume one can of paint covers 10 sq m)?

• A. 56 sq m
• B. 72 sq m
• C. 88 sq m
• D. 104 sq m

Correct answer: C

Rationale: Calculate the areas of each wall and the floor, sum them up, and subtract the area of the water surface (top). Divide the final area by the coverage area per can to determine the number of cans needed.

4. What type of reaction is represented by the following equation: Fe2O3 (s) + 3H2 (g) -> 2Fe (s) + 3H2O (g)

• A. Combustion
• B. Decomposition
• C. Single displacement
• D. Redox reaction

Correct answer: D

Rationale: The given equation involves a transfer of electrons from iron oxide (Fe2O3) to hydrogen gas (H2), resulting in the formation of iron (Fe) and water (H2O). This transfer of electrons indicates a redox reaction, where oxidation and reduction occur simultaneously. In this case, iron is reduced from a higher oxidation state in Fe2O3 to a lower oxidation state in Fe, while hydrogen is oxidized from its elemental state in H2 to form water. Therefore, the correct answer is D: Redox reaction.

5. On the other hand, Ms. Castro notices that the Chief Nurse Executive has charismatic

• A. Possesses inspirational quality that makes followers gets attracted of him and regards
• 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.

6. The free edges of your fingernails and toenails are technically called the:

• A. Lunula (The lunula is the white crescent moon shape at the base of the nail)
• B. Matrix (The matrix is the area under the nail where new nail cells are produced)
• C. Hyponychium (This is the skin under the free edge of the nail)
• D. Free edge

Correct answer: D

Rationale: The free edges of your fingernails and toenails are the parts that extend beyond the fingertip or toe. These edges are commonly referred to simply as the "free edge" because they are not attached to the skin. The lunula is the white crescent moon shape at the base of the nail, the matrix is the area under the nail where new nail cells are produced, and the hyponychium is the skin under the free edge of the nail. Therefore, the correct answer is D.
