Nursing Elites

1. A client who is scheduled for cardiac catheterization to rule out coronary occlusion should be informed by the nurse that:

• A. The procedure is performed in a darkened room in the radiology department
• B. It is necessary to lie quietly on a hard x-ray table for about 4 hours
• C. The room is bright and well lit, and it is best to keep the eyes closed
• D. The client may have feelings of warmth or flushing during the procedure

Correct answer: D

Rationale: Before cardiac catheterization, the nurse should inform the client that the procedure is performed in a darkened room in the radiology department, not the operating room. The client should expect to lie still on an x-ray table for the duration of the procedure, not necessarily for about 4 hours. Keeping the eyes closed is not necessary as the room is usually dimly lit. The client may experience sensations of warmth or flushing during the procedure due to catheter passage and dye injection, making choice D the correct answer.

2. The client is being educated by the nurse on home blood glucose monitoring. Which of the following blood glucose measurements indicates hypoglycemia?

• A. 59 mg/dL (3.3 mmol/L)
• B. 75 mg/dL (4.2 mmol/L)
• C. 108 mg/dL (6 mmol/L)
• D. 119 mg/dL (6.6 mmol/L)

Correct answer: A

Rationale: A blood glucose level of 59 mg/dL (3.3 mmol/L) is considered hypoglycemia, which is an abnormally low blood sugar level. This level requires immediate attention as it can lead to symptoms such as confusion, shakiness, and even loss of consciousness if left untreated. Choices B, C, and D have blood glucose levels within the normal range or slightly higher, indicating euglycemia or normal blood sugar levels, and not hypoglycemia.

3. A client with renal insufficiency and a low red blood cell count asks, 'Is my anemia related to the renal insufficiency?' How should the nurse respond?

• A. Red blood cells produce erythropoietin, which increases blood flow to the kidneys.
• B. Your anemia and renal insufficiency are related to inadequate vitamin D and a loss of bone density.
• C. Erythropoietin is usually released from the kidneys and stimulates red blood cell production in the bone marrow.
• D. Kidney insufficiency inhibits active transportation of red blood cells throughout the blood.

Correct answer: C

Rationale: The correct answer is C. Erythropoietin is produced in the kidney and is released in response to decreased oxygen tension in the renal blood supply. Erythropoietin stimulates red blood cell production in the bone marrow. Anemia in renal insufficiency is often due to decreased erythropoietin production. Anemia and renal insufficiency are not manifestations of vitamin D deficiency as stated in choice B. Choice A is incorrect as erythropoietin does not increase blood flow to the kidneys. Choice D is incorrect because kidney insufficiency does not inhibit active transportation of red blood cells throughout the blood; rather, it affects erythropoietin production and subsequent red blood cell formation.

4. A nurse reviews laboratory results for a client with glomerulonephritis. The client’s glomerular filtration rate (GFR) is 40 mL/min as measured by a 24-hour creatinine clearance. How should the nurse interpret this finding? (Select all that apply.)

• A. Excessive GFR
• B. Reduced GFR
• C. Fluid retention and risks for hypertension
• D. Pulmonary edema

Correct answer: B

Rationale: A GFR of 40 mL/min indicates a reduced glomerular filtration rate. In a healthy adult, the normal GFR ranges between 100 and 120 mL/min. A GFR of 40 mL/min signifies a significant reduction, leading to fluid retention and risks for hypertension and pulmonary edema due to excess vascular fluid. Choices A, C, and D are incorrect. Choice A is incorrect as a GFR of 40 mL/min is not excessive but rather reduced. Choices C and D do not directly address the interpretation of GFR but instead describe potential consequences of a reduced GFR.

5. The nurse assesses a client with advanced cirrhosis of the liver for signs of hepatic encephalopathy. Which finding would the nurse consider an indication of progressive hepatic encephalopathy?

• A. An increase in abdominal girth.
• B. Hypertension and a bounding pulse.
• C. Decreased bowel sounds.
• D. Difficulty in handwriting.

Correct answer: D

Rationale: Difficulty in handwriting is a common early sign of hepatic encephalopathy. Changes in handwriting can indicate progression or reversal of hepatic encephalopathy leading to coma. Choice (A) is a sign of ascites, not hepatic encephalopathy. Hypertension and a bounding pulse (Choice B) are not typically associated with hepatic encephalopathy. Decreased bowel sounds (Choice C) do not directly indicate an increase in serum ammonia level, which is the primary cause of hepatic encephalopathy.
