A nurse is preparing to administer labetalol 40 mg IV to a client. Available is labetalol 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Rationale:

A. Pale and a 24-hr fluid deficit of 30 mL: Mild pallor and a small fluid deficit are not uncommon in early stages of illness and may not require immediate intervention. However, more serious signs of dehydration would take priority for reporting.

B. Temperature 38° C (100.4° F) and pulse rate 124/min: These are within expected limits for an infant with mild infection or fever. While they should be monitored, they are not urgent indicators of severe complications from gastroenteritis.

C. Decreased appetite and irritability: These are common symptoms in infants with viral illnesses, including gastroenteritis. Although they affect comfort and feeding, they are not necessarily indicators of serious fluid or electrolyte imbalance.

D. Sunken fontanels and dry mucous membranes: These are clinical signs of moderate to severe dehydration, which is a serious complication of gastroenteritis in infants. These findings must be reported promptly for urgent intervention to prevent further deterioration.

Rationale:

A. Palpate the client's bladder in 1 hour: Waiting another hour to assess the bladder delays intervention. At 10 hours postpartum with no void, immediate action is needed to stimulate voiding or assess for urinary retention.

B. Place the client's hands in a bowl of cold water: This technique is more commonly used in children and is less effective in stimulating voiding in postpartum adults. It is not a first-line strategy in this context.

C. Have the client listen to running water while on the toilet: This is a noninvasive and effective method to stimulate the urge to void by triggering the micturition reflex. It can help relax pelvic muscles and encourage urination postpartum.

D. Perform effleurage over the client's lower abdomen: Effleurage is a light massage technique used primarily for labor pain management. It is not a recognized or effective method to promote urination in postpartum care.
