A client has a serum potassium level of 2.9 mEq/L. Which action prescribed by the health care provider should the nurse take first?

Choice A reason: This statement is false. A 12-month-old who is 2-days post-op cleft palate repair whose vital signs are within normal limits is not the priority for pain medication. This infant may have some pain from the surgery, but it is likely to be mild and manageable with non-pharmacological interventions, such as distraction, comfort, or oral care.

Choice B reason: This statement is false. A 6-month-old who is crying and becomes calm when held by a parent is not the priority for pain medication. This infant may have some pain from an unknown cause, but it is likely to be transient and responsive to non-pharmacological interventions, such as soothing, rocking, or cuddling.

Choice C reason: This statement is true. An 8-month-old with legs drawn to chest and a temperature of 39.5 degrees C is the priority for pain medication. This infant may have severe pain from an infection, such as appendicitis, meningitis, or urinary tract infection. This infant may also have signs of inflammation, such as fever, leukocytosis, or elevated C-reactive protein. This infant needs immediate pain relief and antibiotic therapy.

Choice D reason: This statement is false. A 4-month-old that has just returned from the recovery room is not the priority for pain medication. This infant may have some pain from the surgery, but it is likely to be moderate and controlled with pharmacological interventions, such as opioids, NSAIDs, or local anesthetics.

Choice A reason: This statement is true. Assessing mental status and level of consciousness is an important consideration for this treatment, as morphine can cause sedation, confusion, and respiratory depression. The nurse should monitor the client's orientation, alertness, and responsiveness, and use a sedation scale to evaluate the degree of sedation.

Choice B reason: This statement is true. Assessing urine output frequently is an important consideration for this treatment, as morphine can cause urinary retention, which can lead to bladder distension, infection, or kidney damage. The nurse should measure the client's urine output and check for signs of bladder fullness or discomfort.

Choice C reason: This statement is false. Monitoring potassium levels is not an important consideration for this treatment, as morphine does not affect the blood potassium level. Potassium is an electrolyte that is essential for the normal function of the heart, muscles, and nerves. Potassium imbalance can be caused by other factors, such as diuretics, vomiting, diarrhea, or acid-base disorders.

Choice D reason: This statement is true. Teaching the family that only the client can press the button for pain medication is an important consideration for this treatment, as PCA Pump allows the client to self-administer a preset dose of morphine within a specified time interval. The family should not press the button for the client, as this can result in overmedication, overdose, or addiction.

Choice E reason: This statement is true. Ensuring there is an order for Naloxone in case of overdose is an important consideration for this treatment, as Naloxone is an antidote that can reverse the effects of morphine in the event of an overdose. Naloxone can restore the client's breathing, blood pressure, and consciousness, and prevent death.

Choice F reason: This statement is true. Assessing CO2 levels is an important consideration for this treatment, as morphine can cause respiratory depression, which can lead to hypercapnia, or high blood carbon dioxide level. Hypercapnia can cause headache, drowsiness, confusion, and coma. The nurse should monitor the client's respiratory rate, depth, and rhythm, and use a capnograph or a blood gas analysis to measure the CO2 level.
