A client with chronic kidney disease receives a prescription for darbepoetin alfa 40 mcg subcutaneous every 7 days.

The darbepoetin alfa vial is labeled, "60 mcg/mL." How many mL should the nurse administer? round to the nearest tenth.

Choice A rationale:

Supplemental oxygen is given to the patient to prevent hypoxia and tissue damage due to pneumonia. Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. Hypoxia occurs when the body or a region of the body is deprived of adequate oxygen supply at the tissue level. It can cause serious damage to your heart, brain, and other organs. Hence, supplemental oxygen is administered to ensure that the patient’s tissues receive adequate oxygen.

Choice B rationale:

While supplemental oxygen can indirectly help lower blood pressure by improving oxygen supply and reducing strain on the heart, it is not primarily used for this purpose. Enalapril, which the patient is already taking, is an angiotensin-converting enzyme (ACE) inhibitor that is commonly used to lower blood pressure and reduce the workload of the heart.

Choice C rationale:

Supplemental oxygen does increase the oxygen saturation and improve respiratory function. However, this is a more general rationale for providing supplemental oxygen and not specific to this patient’s condition of pneumonia.

Choice D rationale:

Supplemental oxygen does not directly dilate the bronchioles or decrease inflammation in the lungs. Medications such as bronchodilators and corticosteroids are typically used for these purposes. In this case, supplemental oxygen is being used to prevent hypoxia and tissue damage due to pneumonia.

A - The injury may require medical attention, as the mother mentioned that the boy is in pain. Correct

This is the correct answer, as it reflects the nurse's assessment of the injury and the appropriate action to take. The nurse should consider the mother's report of pain as a valid indicator of the severity of the injury, and should not dismiss or minimize it.

The nurse should also observe the boy's arm and shoulder for any signs of fracture, dislocation, swelling, bruising, or deformity, and ask him to rate his pain on a scale of 0 to 10. The nurse should then decide whether to refer the boy to a physician or an emergency department for further evaluation and treatment.

B - The abrasions on the boy's leg and hand have healed.

This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The abrasions on the boy's leg and hand are not relevant to his current complaint of arm and shoulder pain, and do not indicate whether he needs medical attention or not. The nurse should focus on the boy's primary concern and not distract him with unrelated questions or comments.

C - The mother describes what she did after her child got injured.

This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The mother's description of what she did after her child got injured may provide some useful information, such as how long ago the injury occurred, what first aid measures were applied, and whether there was any improvement or worsening of symptoms. However, it does not directly answer the question of whether the injury requires medical attention or not. The nurse should listen to the mother's account, but also perform a physical examination and ask relevant questions to assess the injury.

D - The boy lacks coordination when answering the nurse's questions.

This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The boy's lack of coordination when answering the nurse's questions may indicate a possible head injury, concussion, or shock, which are serious complications that require immediate medical attention. However, it does not directly relate to his arm and shoulder pain, which is his main complaint.

The nurse should assess the boy's mental status and neurological function, but also evaluate his arm and shoulder for any signs of damage or inflammation.
