HESI 799 RN Exit Exam
1. The nurse needs to add a medication to a liter of 5% Dextrose in Water (D5W) that is already infusing into a client. At what location should the nurse inject the medication?
- A. Medication port
- B. IV drip chamber
- C. Y-site connector
- D. At the hub of the IV catheter
Correct answer: A
Rationale: The correct answer is the medication port. When adding medication to an already infusing IV solution, it should be done through the medication port to ensure direct delivery into the bloodstream without interrupting the primary IV line. Injecting the medication into the IV drip chamber, Y-site connector, or at the hub of the IV catheter can lead to dilution, inaccurate dosing, or potential blockages in the IV line, which can compromise the effectiveness of the medication and patient safety.
2. In determining the client position for insertion of an indwelling urinary catheter, it is most important for the nurse to recognize which client condition?
- A. High urinary pH
- B. Abdominal ascites
- C. Orthopnea
- D. Fever
Correct answer: C
Rationale: The correct answer is C: Orthopnea. If the client is orthopneic, the nurse needs to adapt the insertion position that does not place the client in a supine position. This means the head of the bed should be elevated as much as possible to facilitate catheter insertion without compromising the client's breathing. High urinary pH (choice A) is not directly relevant to the insertion position of a urinary catheter. Abdominal ascites (choice B) may impact the procedure due to abdominal distension but is not as crucial as orthopnea. Fever (choice D) does not specifically affect the client's position for urinary catheter insertion.
3. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value requires immediate intervention?
- A. Serum glucose of 600 mg/dL
- B. Serum osmolarity of 320 mOsm/kg
- C. Serum sodium of 130 mEq/L
- D. Serum potassium of 5.0 mEq/L
Correct answer: B
Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.
4. A client with acute pancreatitis is admitted with severe abdominal pain. Which assessment finding requires immediate intervention?
- A. Severe abdominal distention
- B. Decreased urine output
- C. Decreased bowel sounds
- D. Increased heart rate
Correct answer: A
Rationale: Severe abdominal distention is a sign of worsening pancreatitis and can indicate complications like bowel obstruction or fluid accumulation. Immediate intervention is necessary to prevent further deterioration. Decreased urine output (Choice B) could indicate renal impairment, decreased bowel sounds (Choice C) are expected in pancreatitis due to paralytic ileus, and an increased heart rate (Choice D) is a common response to pain or stress in acute pancreatitis but may not require immediate intervention unless it is extremely high or persistent.
5. A client with cirrhosis is admitted with hepatic encephalopathy. Which laboratory value is most concerning?
- A. Serum ammonia level of 100 mcg/dl
- B. Bilirubin level of 3.0 mg/dl
- C. Prothrombin time of 18 seconds
- D. Serum sodium level of 135 mEq/L
Correct answer: A
Rationale: A serum ammonia level of 100 mcg/dl is most concerning in a client with hepatic encephalopathy. Elevated serum ammonia levels indicate significant liver dysfunction and an increased risk of worsening encephalopathy. Bilirubin level and prothrombin time are important in assessing liver function, but in the context of hepatic encephalopathy, elevated ammonia levels take precedence as they directly contribute to neurological symptoms. Serum sodium level, though important, is not the primary concern when managing hepatic encephalopathy.
