The nurse is caring for a client with diabetic ketoacidosis (DKA) receiving intravenous (IV) regular insulin. The most recent potassium was 2.9 mEq/L. The nurse should take which priority action:
Assess the client urine output (UOP)
Obtain a 12-lead electrocardiogram (ECG)
Notify the primary healthcare provider (PMHCP)
Stop the regular insulin infusion
The Correct Answer is C
Choice A rationale: Assessing the UOP is important, but not as urgent as correcting the potassium imbalance.
Choice B rationale: Obtaining a 12-lead ECG can help monitor the cardiac status, but it does not address the cause of the problem.
Choice C rationale: The PMHCP can order potassium replacement to prevent cardiac arrhythmias and other adverse effects of low potassium levels.
Choice D rationale: Stopping the regular insulin infusion can worsen the DKA and increase the risk of cerebral edema and coma.

Explanation
Choice A rationale: Tachycardia and petechiae over the chest wall and buccal membranes are signs of fat embolism syndrome, another complication of fractures that occurs when fat globules enter the bloodstream and obstruct pulmonary vessels.
Choice B rationale: Positive Homan's sign with calf tenderness and warmth are signs of deep vein thrombosis, a condition that can occur after prolonged immobilization or surgery.
Choice C rationale: Acute cough, cyanosis, and decreased blood pressure are signs of pulmonary embolism, a life-threatening condition that occurs when a blood clot travels to the lungs and blocks blood flow.
Choice D rationale: These are signs of compartment syndrome, which is a serious complication of fractures that occurs when increased pressure within a closed space compromises blood flow and tissue perfusion. Compartment syndrome can lead to ischemia, necrosis, and nerve damage if not treated promptly.
Correct Answer is C
Explanation
Choice A rationale: BSE will not reduce the risk of dying from breast cancer, but it may help you detect breast cancer earlier, when it is more treatable.
Choice B rationale: BSE should be done once a month, preferably at the same time each month. For women who have menstrual periods, the best time to do BSE is a few days after the period ends, when the breasts are less tender and swollen. For women who do not have menstrual periods, such as those who are pregnant, breastfeeding, or postmenopausal, they can choose a fixed date, such as the first day of each month, to do BSE.
Choice C rationale: For women who have menstrual periods, the best time to do BSE is a few days after the period ends, when the breasts are less tender and swollen. For women who do not have menstrual periods, such as those who are pregnant, breastfeeding, or postmenopausal, they can choose a fixed date, such as the first day of each month, to do BSE.
Choice D rationale: Annual mammograms are recommended for women aged 40 and older, or earlier if they have a high risk of breast cancer and not all women. Women aged less than 30 years should undergo breast ultrasound instead.
