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. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63 mmHg, HCO3 23, and oxygenation saturation (SaO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SaO2 indicate hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low due to hypoxia stimulating hyperventilation, but the given ABG values specifically point to hypoxia as the primary issue.

3. Assessment of the client with an arteriovenous fistula for hemodialysis should include:

• A. inspection for visible pulsations.
• B. palpation of thrill.
• C. percussion for dullness.
• D. auscultation of blood pressure.

Correct answer: B

Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.

4. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

5. A patient has experienced a severe third-degree burn to the trunk in the last 36 hours. Which phase of burn management is the patient in?

• A. Shock phase
• B. Emergent phase
• C. Healing phase
• D. Wound proliferation phase

Correct answer: A

Rationale: The correct answer is A: Shock phase. The shock phase occurs within the first 24-48 hours of burn management. During this phase, the focus is on stabilization, fluid resuscitation, and monitoring for potential complications. Choice B, the Emergent phase, is incorrect as it refers to the initial phase of burn care immediately after the injury. Choice C, the Healing phase, occurs later in the treatment process when the wound starts to repair itself. Choice D, the Wound proliferation phase, is not a recognized phase in burn management.
