Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?
- A. The test determines if the client is anemic and needs iron supplements
- B. The test determines if there is excess glucose building up in the urine
- C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
- D. The test determines the amount of hemoglobin that is coated with glucose
Correct Answer: D
Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.

A client is preparing to undergo a cystoscopy for stones. Which of the following statements indicates that the client understands the procedure?
- A. I better drink a lot of fluid now because I won't be able to after the test.
- B. I will probably see a little blood when I urinate.
- C. I will be able to go home after 3 days in the hospital.
- D. I won't need any pain medicine; this probably will not hurt.
Correct Answer: B
Rationale: The correct answer is, 'I will probably see a little blood when I urinate.' During a cystoscopy, a scope is inserted into the client's bladder to inspect structures or remove objects like stones. This procedure is usually performed under local or general anesthesia. It is common for clients to experience a small amount of blood in their urine (hematuria) or have pink-colored urine after the procedure. The other choices are incorrect because drinking a lot of fluid before the test, staying in the hospital for 3 days, and assuming no pain will be experienced are not accurate statements related to a cystoscopy procedure.
Which of the following conditions may warrant a serum creatinine level?
- A. Rhabdomyolysis
- B. Digitalis toxicity
- C. Glomerulonephritis
- D. All answers are correct
Correct Answer: D
Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.
Mrs. G is seen for follow-up after testing for chronically high blood glucose levels. Her physician diagnoses her with type 1 diabetes. Which of the following information is part of this client's education about this condition?
- A. Type 1 diabetes occurs due to increased carbohydrate intake and lack of exercise
- B. Type 1 diabetes is managed through diet and exercise
- C. Type 1 diabetes is caused by destruction of beta cells in the pancreas
- D. Type 1 diabetes leads to the body's cells rejecting insulin
Correct Answer: C
Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.
A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.
- A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
- B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
- C. The client should lie flat on their back for a specific period following the procedure.
- D. The risks of the procedure include headache, back pain, and infection.
Correct Answer: B
Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.
A healthcare professional is preparing to insert an indwelling catheter in a female client. Which of the following positions of the client is most appropriate for this procedure?
- A. Lithotomy position
- B. Prone position
- C. Dorsal recumbent position
- D. High Fowler's position
Correct Answer: C
Rationale: When preparing to insert an indwelling catheter for a female client, the most appropriate position is the dorsal recumbent position. In this position, the client lies on their back with knees bent. This position allows for easy access to the urethral area for catheter insertion. The lithotomy position, with legs elevated and spread apart, is more invasive and typically used for gynecological exams. The prone position, lying face down, is not suitable for catheter insertion. High Fowler's position, sitting upright at a 90-degree angle, is not ideal for catheter insertion as it does not provide proper access to the perineal area.
