Nursing Elites

1. Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?

• A. Increasing heart rate above normal for the patient's age.
• B. Absent peripheral pulses
• C. Decreasing level of consciousness
• D. Increasing blood pressure

Correct answer: D

Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.

2. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

3. A nurse admits a 3-week-old infant to the special care nursery with a diagnosis of bronchopulmonary dysplasia. As the nurse reviews the birth history, which data would be most consistent with this diagnosis?

• A. Gestational age assessment suggested growth retardation
• B. Meconium was cleared from the airway at delivery
• C. Phototherapy was used to treat Rh incompatibility
• D. The infant received mechanical ventilation for 2 weeks

Correct answer: D

Rationale: The correct answer is 'The infant received mechanical ventilation for 2 weeks.' Bronchopulmonary dysplasia is a condition primarily caused by therapies like positive-pressure ventilation used in the treatment of lung disease. This leads to lung damage and subsequent respiratory problems. Choices A, B, and C are not consistent with the diagnosis of bronchopulmonary dysplasia. Gestational age assessment suggesting growth retardation is more indicative of intrauterine growth restriction, clearing meconium from the airway at delivery is related to potential respiratory issues at birth, and phototherapy for Rh incompatibility is unrelated to bronchopulmonary dysplasia.

4. The parents of a newborn male with hypospadias want their child circumcised. The best response by the nurse is to inform them that

• A. Circumcision is delayed so the foreskin can be used for the surgical repair
• B. This procedure is contraindicated because of the permanent defect
• C. There is no medical indication for performing a circumcision on any child
• D. The procedure should be performed as soon as the infant is stable

Correct answer: A

Rationale: Circumcision is delayed so the foreskin can be used for the surgical repair. Even if mild hypospadias is suspected, circumcision is not done to save the foreskin for surgical repair if needed. Choice B is incorrect because circumcision is not contraindicated due to a permanent defect; it is delayed for potential surgical needs. Choice C is incorrect as there are situations where a circumcision may be indicated for medical or cultural reasons. Choice D is incorrect because circumcision for hypospadias-related repair is not done immediately but rather delayed to preserve the foreskin for potential reconstructive surgery.

5. To palpate the liver during a head-to-toe physical assessment, the nurse should

• A. put pressure on the biopsy site using a sandbag
• B. elevate the head of the bed to facilitate breathing
• C. place the patient on the right side with the bed flat
• D. check the patient's post-biopsy coagulation studies

Correct answer: C

Rationale: To palpate the liver effectively during a head-to-toe physical assessment, the patient should be positioned on the right side with the bed flat. This position helps to splint the biopsy site and allows for proper palpation of the liver. Elevating the head of the bed has no direct relevance to palpating the liver. Checking coagulation studies is done before the biopsy and is unrelated to palpation. Putting pressure on the biopsy site using a sandbag is not an appropriate way to facilitate liver palpation as it does not provide the necessary support and stabilization needed for the procedure.
