Solution Steps

Step 1: Naming the Compound \(\mathrm{Li}_{2} \mathrm{O}\)

The compound \(\mathrm{Li}_{2} \mathrm{O}\) consists of lithium (Li) and oxygen (O). Lithium is a metal and oxygen is a non-metal, so this is an ionic compound. The name of the compound is formed by naming the metal first followed by the non-metal with an "-ide" suffix.

Step 2: Determining the Charge on Each Ion in \(\mathrm{Li}_{2} \mathrm{O}\)

Lithium typically forms a \(+1\) charge as it loses one electron to achieve a stable electron configuration. Oxygen typically forms a \(2-\) charge as it gains two electrons to achieve a stable electron configuration. Since the compound is neutral, the charges must balance: \[ 2 \times (+1) + (-2) = 0 \]

Step 3: Naming the Compound \(\mathrm{CaS}\)

The compound \(\mathrm{CaS}\) consists of calcium (Ca) and sulfur (S). Calcium is a metal and sulfur is a non-metal, so this is also an ionic compound. The name of the compound is formed by naming the metal first followed by the non-metal with an "-ide" suffix.

Step 4: Determining the Charge on Each Ion in \(\mathrm{CaS}\)

Calcium typically forms a \(2+\) charge as it loses two electrons to achieve a stable electron configuration. Sulfur typically forms a \(2-\) charge as it gains two electrons to achieve a stable electron configuration. Since the compound is neutral, the charges must balance: \[ (+2) + (-2) = 0 \]

Final Answer

\[ \boxed{\text{Name of } \mathrm{Li}_{2} \mathrm{O} \text{ : Lithium oxide}} \] \[ \boxed{\text{Li charge: } +1} \] \[ \boxed{\text{O charge: } -2} \] \[ \boxed{\text{Name of CaS: Calcium sulfide}} \] \[ \boxed{\text{Ca charge: } +2} \] \[ \boxed{\text{S charge: } -2} \]

A nurse is assessing a client who is 3 days postpartum and is breastfeeding. The nurse notes that the fundus is three fingerbreadths below the umbilicus, lochia rubra is moderate, and the breasts are hard and warm to palpation. Which of the following interpretations of these findings should the nurse make? - The client is exhibiting early indications of mastitis. Additional interventions are not indicated at this time. Application of a heating pad to the breasts is indicated. The client should be advised to remove her nursing bra.
