1. When does regular insulin typically peak?

• A. 30 minutes to 2 ½ hours
• B. 1 to 3 hours
• C. 6 to 14 hours
• D. 1 to 5 hours

Correct answer: D

Rationale: Regular insulin usually peaks around 1 to 5 hours after administration. This peak time frame is important to consider when managing blood glucose levels and timing meals to coincide with insulin activity. Choice A, '30 minutes to 2 ½ hours,' is incorrect because regular insulin typically peaks later. Choice B, '1 to 3 hours,' is not the most accurate as the peak for regular insulin can extend beyond 3 hours. Choice C, '6 to 14 hours,' is incorrect as this timeframe is more indicative of long-acting insulins, not regular insulin.

2. A client with heart failure is being instructed on laxative use. Which of the following laxatives should the client avoid?

• A. Sodium phosphate
• B. Psyllium
• C. Bisacodyl
• D. Polyethylene glycol

Correct answer: A

Rationale: The correct answer is A: Sodium phosphate. Clients with heart failure often follow a sodium-restricted diet. Sodium phosphate laxatives can lead to sodium absorption, causing fluid retention, which is contraindicated in heart failure. It is crucial to avoid sodium phosphate laxatives in these clients to prevent exacerbation of fluid overload and heart failure symptoms. Psyllium (choice B), Bisacodyl (choice C), and Polyethylene glycol (choice D) are not contraindicated in clients with heart failure and can be used safely for bowel management.

3. A nurse is evaluating teaching for a client who has Rheumatoid Arthritis and a new prescription for Methotrexate. Which of the following statements by the client indicates understanding of the teaching?

• A. I will be sure to return to the clinic at least once a year to have my blood drawn while I'm taking methotrexate.
• B. I will take this medication on an empty stomach.
• C. I'll let the doctor know if I develop sores in my mouth while taking this medication.
• D. I should stop taking oral contraceptives while I'm taking methotrexate.

Correct answer: C

Rationale: Ulcerations in the mouth, tongue, or throat are often the first signs of methotrexate toxicity and should be reported to the provider immediately.

4. A healthcare professional is reviewing the laboratory results of a client who is taking Lithium for Bipolar Disorder. Which of the following findings should the healthcare professional report to the provider immediately?

• A. Lithium level of 1.0 mEq/L
• B. Potassium level of 3.5 mEq/L
• C. Sodium level of 140 mEq/L
• D. Creatinine level of 1.0 mg/dL

Correct answer: D

Rationale: A creatinine level of 1.0 mg/dL should be reported to the provider immediately. While a lithium level of 1.0 mEq/L falls within the therapeutic range, a creatinine level of 1.0 mg/dL could suggest early signs of kidney dysfunction, especially concerning in a client on long-term lithium therapy. It is crucial to monitor kidney function closely because lithium can be nephrotoxic over time. Elevated creatinine levels may indicate impaired kidney function and should prompt immediate reporting to the healthcare provider. Potassium and sodium levels within normal range are not immediate concerns when compared to potential kidney issues.

5. A client is prescribed Lithium. Which of the following laboratory values should be monitored to assess for potential toxicity?

• A. Serum sodium
• B. Serum lithium
• C. Serum potassium
• D. Serum calcium

Correct answer: B

Rationale: When a client is prescribed Lithium, monitoring serum lithium levels is crucial to ensure they remain within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels helps prevent adverse effects associated with lithium toxicity, such as nausea, vomiting, diarrhea, tremors, and confusion.
