Heparin 7.,000 units is ordered. Heparin S.000 units per mL is available, How many milliliters (mL) should the nurse administer?

Choice A reason: 363 is not the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 3.5 kg, not 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 3.5 and 10 kg is 100 mL/kg¹.

Choice B reason: 727 is not the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 10 kg, not 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 10 and 20 kg is 1000 mL plus 50 mL for every kg over 10¹.

Choice C reason: 1300 is the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 10 and 20 kg is 1000 mL plus 50 mL for every kg over 10¹. Therefore, for an infant who weighs 16 kg, the daily maintenance fluid requirement is 1000 mL plus 50 mL times 6, which equals 1300 mL.

Choice D reason: 1600 is not the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 20 kg, not 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 10 and 20 kg is 1000 mL plus 50 mL for every kg over 10¹. For infants who weigh more than 20 kg, the formula is 1500 mL plus 20 mL for every kg over 20¹.

Choice A reason: This statement is true. This client may have a high tolerance to opioids and require a higher dose for pain control, as tolerance is a condition where the body becomes less responsive to the effects of a drug over time, and needs more of the drug to achieve the same effect. Tolerance can develop from chronic or repeated use of opioids, and can vary from person to person. The nurse should assess the client's pain level, history of opioid use, and response to the medication, and adjust the dose accordingly.

Choice B reason: This statement is false. Clients with a history of opioid abuse should not be denied an opioid analgesic, as opioids are effective and appropriate medications for acute pain management, especially after surgery. The nurse should not discriminate or stigmatize the client based on their history of opioid abuse, but rather provide compassionate and evidence-based care. The nurse should also use a multimodal approach to pain management, which involves using non-opioid analgesics, adjuvant medications, and non-pharmacological interventions, such as ice, heat, massage, or relaxation techniques.

Choice C reason: This statement is false. This client should not wait until their pain is severe, 10/10 before taking a high dose opioid, as this can result in poor pain control, increased stress, and delayed recovery. The nurse should encourage the client to take the medication as prescribed, and to report their pain level regularly. The nurse should also educate the client about the benefits of preventive analgesia, which involves taking the medication before the pain becomes severe, and maintaining a steady blood level of the drug.

Choice D reason: This statement is false. The client's self-report of pain may not be disregarded if they have a history of opioid abuse, as pain is a subjective and personal experience, and the client is the best judge of their own pain. The nurse should not assume that the client is exaggerating, lying, or drug-seeking, but rather respect and validate the client's pain report. The nurse should also use objective indicators of pain, such as vital signs, facial expressions, body movements, and behavioral changes, to support the client's pain assessment.
