The nurse plans care for a client experiencing a hyperglycemic-hyperosmolar state (HHS). The nurse should anticipate which prescriptions from the primary healthcare provider (PHCP)?
- A. 0.9% saline infusion
- B. Glargine insulin
- C. Sodium polystyrene
- D. Sodium bicarbonate
Correct Answer: A
Rationale: HHS involves severe hyperglycemia and dehydration. 0.9% saline corrects fluid loss. Glargine is long-acting and not ideal for acute HHS, sodium polystyrene treats hyperkalemia, and bicarbonate is rarely used unless pH is critically low.

The nurse is caring for a client who has diabetic ketoacidosis (DKA). Which of the following would indicate the client is achieving the treatment goals?
- A. Mean arterial pressure (MAP) 71 mmHg
- B. Potassium 3.3 mEq/L (mmol) [3.5-5 mEq/L]
- C. Blood glucose 255 mg/dL (14.15 mmol/L) [70-110 mg/dL, 4.0-11.0 mmol/L]
- D. Serum pH 7.33 [7.35 and 7.45]
Correct Answer: D
Rationale: In DKA, treatment aims to correct acidosis, hyperglycemia, and electrolyte imbalances. A serum pH of 7.33 is closer to the normal range (7.35-7.45), indicating improvement in acidosis. MAP of 71 mmHg is low, potassium is below normal, and glucose remains elevated, suggesting ongoing issues.
The nurse is assisting a client with their newly prescribed insulin pump. The nurse understands which insulin is commonly loaded into the pump?
- A. Rapid acting
- B. Ultra long-acting insulin
- C. Intermediate acting
- D. Long acting
Correct Answer: A
Rationale: Rapid-acting insulin, such as lispro or aspart, is used in insulin pumps to mimic physiological insulin delivery for basal and bolus dosing. Long-acting or intermediate-acting insulins are not suitable for pumps.
The following scenario applies to the next 1 items
The emergency department (ED) nurse is caring for a 66-year-old male client
Item 1 of 1
History and Physical
2000: 66-year male arrives at the emergency department (ED) following a recommendation by his primary healthcare provider (PHCP). The client called his PHCP in the morning, reporting a headache, feeling unwell, fatigue, and thirst. He could not check his blood glucose because he reports being out of testing supplies for two weeks. He also reports being unable to take his prescribed antihypertensive and antidiabetic medications for one week because he lost his job. On exam, the client reports feeling fatigued and thirsty. He is alert and completely oriented. His physical exam was within normal limits except for a thready pulse with a rate of 119/minute.
The client has a medical history of type II diabetes mellitus, congestive heart failure (CHF), hypertension, and hyperlipidemia. He is prescribed atorvastatin, metformin, and lisinopril.
Vital Signs
Oral Temperature 98o F (36.7o C)
Pulse 119/minute
Respirations 19/minute
Blood pressure 98/52 mm Hg
Oxygen saturation 96% on room air
Physician Orders
Obtain intravenous (IV) access
Five units of regular insulin via intravenous push (IVP)
Infuse two liters of 0.9% saline over one hour
Obtain capillary blood glucose (CBG) every two hours
Potassium chloride 20 mEq by mouth x 1 dose
Implement seizure precautions
The nurse reviews laboratory work ordered by the primary healthcare provider (PHCP). The nurse obtains physician orders for this client with hyperosmolar hyperglycemic state (HHS) . The nurse is preparing to implement the physician's orders. Which order should the nurse clarify with the physician?
- A. Infuse two liters of 0.9% saline over one hour
- B. Obtain capillary blood glucose every two hours
- C. Potassium chloride 20 mEq by mouth
- D. Implement seizure precautions
Correct Answer: A
Rationale: Infusing 2 liters of saline in one hour is too rapid for HHS, risking fluid overload. Slower infusion (e.g., 1 liter over 2-4 hours) is safer. Other orders align with HHS management.
The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory tests require careful monitoring?
- A. Potassium
- B. Sodium
- C. Glucose
- D. Magnesium
Correct Answer: B
Rationale: SIADH causes water retention, diluting sodium and risking hyponatremia. Close sodium monitoring prevents neurological complications like seizures or coma.
The nurse is conducting a health screening at a local health fair. Which of the following should the nurse recognize as a risk factor for developing type II diabetes mellitus?
- A. Gestational diabetes
- B. Metabolic syndrome
- C. Chronic corticosteroid use
- D. Gastric bypass surgery
- E. Obesity
Correct Answer: A, B, C, E
Rationale: Gestational diabetes, metabolic syndrome, chronic steroids, and obesity increase type 2 diabetes risk via insulin resistance. Gastric bypass often improves glucose control.
