Nursing Elites

1. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote retraction of the intercostal accessory muscles of respiration
• C. To promote bronchodilation and effective airway clearance
• D. To decrease pressure on the medullary center which stimulates breathing

Correct answer: A

Rationale: Elevating the head of the bed to 30 degrees is done to reduce abdominal pressure on the diaphragm, aiding in lung expansion and oxygenation. This position helps improve respiratory mechanics by allowing the diaphragm to move more effectively. Choice B is incorrect as elevating the head of the bed does not directly promote retraction of the intercostal accessory muscles of respiration. Choice C is incorrect because although elevating the head of the bed can assist with airway clearance, its primary purpose in ARDS is to decrease pressure on the diaphragm. Choice D is incorrect because reducing pressure on the medullary center is not the main goal of elevating the head of the bed; the focus is on enhancing lung function and oxygen exchange.

2. In Duchenne muscular dystrophy, if a child has a Gower sign, what behavior should the nurse expect the child to exhibit?

• A. Stands from sitting on the floor by using hands to walk up legs
• B. Exhibits muscular atrophy of upper and lower extremities
• C. Is unable to stand because of contractures of both hips
• D. Walks with an unsteady gait and slaps feet on the floor

Correct answer: A

Rationale: The Gower sign is a characteristic finding in Duchenne muscular dystrophy where a child uses hands to walk up the legs when standing from a sitting position due to proximal muscle weakness. This behavior is indicative of the child trying to compensate for weak hip and thigh muscles. Choices B, C, and D are incorrect because they do not describe the specific behavior associated with the Gower sign. Muscular atrophy, contractures of both hips, and an unsteady gait with foot slapping are not directly related to the Gower sign.

3. Two days after an abdominal hysterectomy, an elderly female with diabetes has a syncopal episode. The nurse determines that her vital signs are within normal limits, but her blood sugar is 325 mg/dL or 18.04 mmol/L (SI). What intervention should the nurse implement first?

• A. Administer regular insulin per sliding scale
• B. Cancel the client's dinner tray
• C. Give the client 4 ounces (120 mL) of orange juice
• D. Administer the next scheduled dose of metformin

Correct answer: A

Rationale: In this case, the nurse should implement the intervention of administering regular insulin per sliding scale. High blood sugar levels, as indicated by a reading of 325 mg/dL, require insulin administration to prevent complications such as hyperglycemia. Canceling the client's dinner tray (choice B) would not address the immediate need to lower the blood sugar level. Giving the client orange juice (choice C) might further increase the blood sugar level as it contains sugar. Administering the next scheduled dose of metformin (choice D) is not appropriate as metformin is not typically used for acute management of high blood sugar levels.

4. A client prescribed warfarin is being taught about dietary modifications by a nurse. Which statement by the client indicates understanding of the teaching?

• A. ''I need to avoid foods high in vitamin C.''
• B. ''I should eat a consistent amount of vitamin K each day.''
• C. ''I can eat as many leafy greens as I want.''
• D. ''I should not worry about any changes in my diet.''

Correct answer: B

Rationale: The correct answer is B. Consistency in vitamin K intake is crucial for clients on warfarin to maintain stable anticoagulation levels. Option A is incorrect as vitamin C does not directly interact with warfarin. Option C is incorrect because although leafy greens are high in vitamin K, excessive consumption can affect warfarin's effectiveness. Option D is incorrect as any changes in diet, particularly in vitamin K intake, can impact the efficacy of warfarin.

5. A client with complaints of shortness of breath and abdominal pain 1 week after bariatric surgery is admitted for follow-up evaluation. Which assessment finding warrants immediate intervention by the nurse?

• A. Rectal temperature of 101°F
• B. Complaints of left shoulder pain
• C. Blood pressure of 88/50 mmHg
• D. Sustained sinus tachycardia

Correct answer: C

Rationale: A blood pressure of 88/50 mmHg indicates possible hypovolemia or shock, which requires immediate attention. Hypotension can be a sign of decreased perfusion to vital organs, potentially leading to organ failure. The other options, such as a rectal temperature of 101°F, complaints of left shoulder pain, or sustained sinus tachycardia, while important, do not present the same level of immediate threat to the client's well-being as a critically low blood pressure.
