Nursing Elites

1. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

• A. Diarrhea and Vomiting
• B. Dizziness and Drowsiness
• C. Metallic taste
• D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

2. Renal failure is broadly divided into specific categories. Which type is the type II diabetic patient most likely to experience secondary to diabetes?

• A. Acute renal failure (ARF)
• B. Intermittent renal failure (IRF)
• C. Chronic renal failure (CRF)
• D. Reversible renal failure (RRF)

Correct answer: C

Rationale: Diabetic nephropathy is a common complication in type II diabetic patients, leading to chronic renal failure (CRF). Chronic renal failure (CRF) and acute renal failure (ARF) are the two main categories of renal failure. CRF can result from various conditions including diabetic nephropathy, chronic glomerulonephritis, chronic pyelonephritis, polycystic kidney disease, connective tissue disorders, and amyloidosis. Unlike acute renal failure, chronic renal failure is irreversible. Timely treatment of ARF can often lead to reversibility, but CRF may require renal replacement therapy (RRT) or kidney transplant. Therefore, the correct answer is chronic renal failure (CRF). Intermittent renal failure (IRF) and reversible renal failure (RRF) are not recognized medical terms for distinct types of renal failure, making choices B and D incorrect.

3. A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?

• A. The patient states he had a manic episode a week ago
• B. The patient states he has been having diarrhea every day
• C. The patient presents as severely depressed
• D. The patient has a rash and pruritus on his arms and legs

Correct answer: B

Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.

4. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is:

• A. Surgical repair of a diseased coronary artery
• B. Placement of an automatic internal cardiac defibrillator
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow
• D. Non-invasive radiographic examination of the heart

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.

5. In children suspected to have a diagnosis of diabetes, which one of the following complaints would be most likely to prompt parents to take their school-age child for evaluation?

• A. Polyphagia
• B. Dehydration
• C. Bedwetting
• D. Weight loss

Correct answer: C

Rationale: The correct answer is 'Bedwetting.' One of the initial symptoms of type 1 diabetes in children is bedwetting. Parents are likely to notice bedwetting in a school-age child, prompting them to seek evaluation. Polyphagia (excessive hunger) and weight loss are also common symptoms of diabetes but may not be as readily noticeable to parents compared to bedwetting. Dehydration is a consequence of diabetes rather than an early symptom that would prompt parents for evaluation.
