Nursing Elites

1. Which of the following infant behaviors demonstrates the concept of object permanence?

• A. The infant cries when his mother leaves the room.
• B. The infant looks at the floor to find a toy that he was playing with and dropped.
• C. The infant picks up another toy after the one he was playing with rolls under the couch.
• D. The infant participates in a game of patty-cake.

Correct answer: B

Rationale: Object permanence occurs when the infant learns that something or someone still exists even though they might not be able to see it or them. This typically develops between 9 and 10 months of age. The correct answer, 'The infant looks at the floor to find a toy that he was playing with and dropped,' demonstrates object permanence as the infant understands that the toy still exists even though it is temporarily out of sight. Choices A and C do not directly relate to object permanence as the behaviors described do not necessarily indicate an understanding of objects existing when out of sight. Choice D is incorrect as participating in a game of patty-cake does not involve demonstrating object permanence. Peek-a-boo is a more suitable example of a game that demonstrates object permanence, as the infant continues to look for the hidden face, understanding that it still exists even though temporarily unseen.

2. How can a diet high in fiber content benefit an individual?

• A. aid in rapid weight loss.
• B. reduce diabetic ketoacidosis.
• C. lower cholesterol.
• D. reduce the requirement for folate.

Correct answer: C

Rationale: A diet high in fiber content can help lower cholesterol levels. Fiber-rich foods such as grains, apples, potatoes, and beans are known to aid in reducing cholesterol by binding to cholesterol in the digestive system and preventing its absorption into the bloodstream. Choice A is incorrect as the question does not specify losing weight rapidly but rather focuses on the benefits of a high-fiber diet, which includes aiding in weight management through promoting satiety and regulating digestion. Choice B is incorrect because while fiber helps manage blood sugar levels, it is not directly related to reducing diabetic ketoacidosis, a serious complication of diabetes. Choice D is incorrect as a high-fiber diet does not reduce the need for folate; however, it can aid in the absorption of folate and other essential nutrients.

3. The LPN is preparing to ambulate a client post total knee replacement. Which of the following actions should the nurse perform prior to ambulating the client?

• A. Assist the client to a sitting position at the edge of the bed
• B. Have the client march in place for 30 seconds
• C. Have the client raise his arms above his head
• D. Ask the client the last time he fell

Correct answer: A

Rationale: The correct action to perform before ambulating a client post total knee replacement is to assist the client to a sitting position at the edge of the bed. This step is crucial to prevent orthostatic hypotension and ensure the client is ready to stand and walk safely. Having the client march in place or raise his arms above his head are not necessary preparations for ambulation. While knowing about the client's fall history is important for safety reasons, it is not the priority action immediately before ambulating the client.

4. 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.

5. How can a diet high in fiber content benefit an individual?

• A. aid in weight loss.
• B. reduce diabetic ketoacidosis.
• C. lower cholesterol.
• D. reduce the need for folate.

Correct answer: C

Rationale: A diet high in fiber content can help lower cholesterol levels by reducing the absorption of cholesterol in the bloodstream. Fiber-rich foods, like grains, apples, potatoes, and beans, can aid in this process. While fiber can aid in weight loss by promoting a feeling of fullness and aiding digestion, it is not primarily for fast weight loss. Fiber does not directly reduce the risk of diabetic ketoacidosis, which is more related to managing blood sugar levels through insulin therapy and dietary control. Folate is a B vitamin that is essential for various bodily functions and is not influenced by fiber intake. Therefore, the correct answer is to lower cholesterol, as fiber plays a significant role in this benefit.
