Correct Answer is D

Explanation

A. 0.45% Sodium Chloride: This is a hypotonic solution, which is not appropriate for a client with normal serum osmolality (290 mOsm/kg). It may cause fluid shifts that are not desirable in this context.
B. 10% dextrose in water: This hypertonic solution is generally used for providing calories rather than correcting fluid imbalance and is not suitable for initial rehydration in this scenario.
C. 5% dextrose in water: This solution is isotonic in the bag but becomes hypotonic in the body. It is not the best choice for rehydrating a client with normal serum osmolality and significant fluid loss.
D. 0.9% Sodium Chloride: This isotonic solution is appropriate for rehydration in a client with normal serum osmolality. It helps restore extracellular fluid volume without causing fluid shifts, making it ideal for this situation.

A. Crush the medication and administer it through the tube B. Provide the medication orally for the client to swallow C. Ask the healthcare provider to prescribe the medication as an elixir for tube administration D. Dissolve the medication in water and administer it through the tube

Correct Answer is C

Explanation

A. Crush the medication and administer it through the tube: Crushing sustained-release medications can alter their release mechanism, leading to potential overdose or ineffective treatment. Sustained-release formulations should not be crushed.
B. Provide the medication orally for the client to swallow: This option is not appropriate because the client has a gastrostomy tube, and oral administration is not suitable for this route.
C. Ask the healthcare provider to prescribe the medication as an elixir for tube administration: This is the correct approach as it ensures the medication is in a form suitable for administration through the gastrostomy tube without altering its release properties.
D. Dissolve the medication in water and administer it through the tube: Dissolving sustained-release tablets is not recommended as it may compromise the medication's intended release mechanism.
