Nursing Elites

1. How can a nurse recognize that a chronic renal failure client's AV shunt is patent?

• A. Absence of a bruit
• B. Presence of a thrill
• C. Blood return from the shunt
• D. Urine output greater than 30 ml/hr

Correct answer: B

Rationale: The correct assessment to determine the patency of an AV shunt in a chronic renal failure client is the presence of a thrill. A thrill is a vibration or buzzing sensation felt over the shunt site, indicating good blood flow through the shunt. While the presence of a bruit is also important for assessing an AV shunt, a thrill is a more specific indicator of patency. Blood return from the shunt is related to cannulation and not necessarily an indicator of patency. Urine output greater than 30 ml/hr is not directly related to the assessment of an AV shunt's patency.

2. One of the major functions of the kidneys in maintaining normal fluid balance is:

• A. the manufacture of antidiuretic hormone.
• B. the regulation of calcium and phosphate balance.
• C. the regulation of the pH of the extracellular fluid.
• D. the control of aldosterone levels.

Correct answer: C

Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.

3. A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?

• A. The patient may be developing CHF
• B. The patient may be having a MI
• C. The patient may be developing COPD
• D. The patient may be having an onset of PVD

Correct answer: B

Rationale: In this scenario, the patient's symptoms of shortness of breath (SOB) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness. Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or peripheral vascular disease (PVD).

4. While Fluorouracil (5FU®) is being infused, a client complains of burning at the IV site. What should the nurse do first?

• A. Aspirate the IV site for blood return.
• B. Slow the infusion.
• C. Inspect the IV site.
• D. Stop the infusion.

Correct answer: C

Rationale: The correct first action for the nurse is to inspect the IV site. This is important to assess for any signs of infiltration or extravasation, which could be causing the burning sensation. Aspirating the IV site for blood return (Choice A) may not be the initial priority as it does not directly address the client's complaint of burning. Slowing the infusion (Choice B) may help alleviate discomfort but should not be done before inspecting the site. Stopping the infusion (Choice D) may be necessary, but inspecting the site should come first to determine the appropriate course of action.

5. A nurse is caring for a patient in the step-down unit. The patient has signs of increased intracranial pressure. Which of the following is not a sign of increased intracranial pressure?

• A. Bradycardia
• B. Increased pupil size bilaterally
• C. Change in LOC
• D. Vomiting

Correct answer: B

Rationale: The correct answer is 'Increased pupil size bilaterally.' When assessing for signs of increased intracranial pressure, bilateral pupil dilation is not typically associated with this condition. Instead, unilateral pupil changes, especially one pupil becoming dilated or non-reactive while the other remains normal, are indicative of increased ICP. Bradycardia, a change in level of consciousness (LOC), and vomiting are commonly seen in patients with increased intracranial pressure due to the brain's response to the rising pressure. Therefore, the presence of bilateral pupil dilation goes against the typical pattern observed in patients with increased intracranial pressure.
