Which of the following is most appropriate when the nurse assesses the intensity of the client's pain?

A. Reading back the calcium level result to the lab technician: Reading back results to the lab technician is a good practice to ensure accurate communication. The nurse verifies that they have received the correct information and confirms the accuracy of the result.

B. Document the time the call was received & the lab technician's name and date of birth. This was not selected because while documenting the time of the call and the lab technician's information may be useful for record-keeping purposes, it is not directly related to the immediate management of the client's low calcium level. Therefore, it is not essential to the immediate actions required in response to the lab result.

C. Reporting the elevated calcium level to the client's physician: An abnormally low calcium level (hypocalcemia) of 6.3 mg/dL requires prompt notification to the client's physician for further evaluation and intervention.

D. Confirming the client's full name, date of birth, & medical record number with the lab technician: Verifying the client's identity and medical record number ensures that the lab results are correctly matched to the right patient, minimizing the risk of errors in patient care.

E. Documenting the low calcium level in the client's electronic medical record: Documenting the calcium level in the client's electronic medical record ensures that the result is recorded for future reference and continuity of care. Accurate documentation is essential for tracking the client's health status and treatment outcomes.

A. Isotonic: Isotonic fluids have a similar osmolarity to extracellular fluid and are often used for volume replacement in clients with fluid volume deficits, such as those with gastroenteritis. Isotonic fluids help to expand intravascular volume without causing significant shifts in fluid and electrolyte balance.

B. Hypotonic: Hypotonic fluids have a lower osmolarity than extracellular fluid and are typically used to rehydrate cells in cases of cellular dehydration. While hypotonic fluids can replenish intracellular volume, they are not typically used as initial replacement fluids for clients with fluid volume deficits, especially if there is risk of exacerbating extracellular fluid deficit.

C. Hypertonic: Hypertonic fluids have a higher osmolarity than extracellular fluid and are often used to expand intravascular volume in specific situations, such as severe hyponatremia or hypovolemic shock. However, they are not typically used as initial replacement fluids for clients with gastroenteritis and fluid volume deficits.

D. Colloid: Colloids are solutions containing large molecules, such as albumin or starches, which remain within the vascular space and exert oncotic pressure to draw fluid into the intravascular compartment. While colloids may be used in some cases of severe volume deficit, they are not typically used as initial replacement fluids for clients with gastroenteritis.
