1. A male client with a tentative diagnosis of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) has a history of type 2 diabetes that is being controlled with an oral diabetic agent, tolazamide (Tolinase). Which of the following is the most important laboratory test for confirming this disorder?
- A. Serum potassium level
- B. Serum sodium level
- C. Arterial blood gas (ABG) values
- D. Serum osmolarity
Correct answer: D
Rationale: Serum osmolarity is the most important laboratory test for confirming hyperosmolar hyperglycemic nonketotic syndrome (HHNS). HHNS is characterized by severe hyperglycemia and dehydration without ketoacidosis. Elevated serum osmolarity indicates increased solute concentration in the blood, which is a hallmark of HHNS. Serum potassium level (Choice A) is important in conditions like diabetic ketoacidosis rather than HHNS. Serum sodium level (Choice B) may be affected in HHNS but is not the primary test for confirming the disorder. Arterial blood gas (ABG) values (Choice C) are more useful in assessing acid-base status, which is not the primary concern in HHNS.
2. A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?
- A. Use the catheter for the next laboratory blood draw.
- B. Monitor the central venous pressure through this line.
- C. Access the line for the next intravenous medication.
- D. Place a heparin or heparin/saline dwell after hemodialysis.
Correct answer: D
Rationale: The most appropriate action for the nurse after a central line catheter placement for hemodialysis is to place a heparin or heparin/saline dwell after hemodialysis treatment. This helps prevent clot formation in the line and maintain patency for future use. Using the catheter for blood draws is not recommended as it may increase the risk of infection. Monitoring central venous pressure is not indicated with this type of catheter. Accessing the line for medications is also not recommended to prevent complications and ensure the line is solely used for hemodialysis purposes.
3. A client with a diagnosis of renal failure is receiving hemodialysis. Which assessment finding should the nurse report to the healthcare provider immediately?
- A. The client's blood pressure is 130/80 mm Hg.
- B. The client gains 1 kg in 24 hours.
- C. The client's potassium level is 5.5 mEq/L.
- D. The client's weight decreases by 0.5 kg in 24 hours.
Correct answer: C
Rationale: A potassium level of 5.5 mEq/L (C) is elevated and concerning in a client with renal failure receiving hemodialysis, as it can lead to life-threatening cardiac arrhythmias. Monitoring blood pressure (A), weight gain (B), and weight loss (D) are essential in clients on hemodialysis, but an elevated potassium level poses an immediate risk that requires prompt intervention.
4. When a male Korean-American client looks away when asked by the nurse to describe his problem, what is the best initial nursing action?
- A. Ask for assistance from social services to find a Korean interpreter.
- B. Establish indirect eye contact with the client.
- C. Allow several minutes for the client to respond.
- D. Repeat the question using simpler language.
Correct answer: C
Rationale: In this scenario, the best initial nursing action is to allow several minutes for the client to respond. This approach respects the cultural norms of the client, as in some cultures, direct eye contact may be perceived as disrespectful or intrusive. By giving the client time to gather his thoughts and respond at his own pace, the nurse promotes effective communication and demonstrates cultural sensitivity. Asking for assistance from social services to find a Korean interpreter (Choice A) may be necessary for further communication but is not the best initial action. Establishing indirect eye contact (Choice B) may still make the client uncomfortable. Repeating the question using simpler language (Choice D) may not address the underlying cultural aspect affecting the client's response.
5. A nurse is preparing to administer insulin to a client with DM. The nurse understands that the peak time for rapid-acting insulin, such as lispro (Humalog), is:
- A. 30 minutes to 1 hour after administration.
- B. 1 to 2 hours after administration.
- C. 2 to 4 hours after administration.
- D. 3 to 5 hours after administration.
Correct answer: A
Rationale: The correct answer is A: 30 minutes to 1 hour after administration. Rapid-acting insulins like lispro, such as Humalog, peak quickly within 30 minutes to 1 hour after administration. This peak time is crucial to monitor for potential hypoglycemia, which is most likely to occur during this period. Choice B is incorrect as it suggests a longer peak time for rapid-acting insulin, which is inaccurate. Choices C and D are also incorrect because they indicate even longer peak times, which do not align with the rapid onset and peak action of lispro insulin.
