LPN Fundamentals Practice Questions

Correct Answer: C

Rationale: Assisting the client with early ambulation is crucial in preventing respiratory complications after abdominal surgery. Early ambulation helps to prevent conditions like atelectasis and pneumonia by promoting lung expansion and preventing pooling of respiratory secretions. It also aids in improving circulation, reducing the risk of deep vein thrombosis, and enhancing overall recovery. Instructing the client to exhale into an incentive spirometer (Choice A) is beneficial for lung expansion but is more focused on respiratory therapy rather than preventing complications. Repositioning the client every 8 hours (Choice B) is important for preventing pressure ulcers but is not directly related to preventing respiratory complications. Maintaining the client on bed rest for the first 48 hours (Choice D) can lead to complications such as atelectasis, pneumonia, and deep vein thrombosis due to decreased lung expansion and mobility.

Correct Answer: B

Rationale: Correct! Hyperkalemia is a condition characterized by high levels of potassium in the blood. To manage hyperkalemia, it is essential to decrease the intake of potassium-rich foods since excess potassium can worsen the condition. By understanding the need to decrease potassium-rich foods, the client shows comprehension of the dietary management required for hyperkalemia. Choice A is incorrect because increasing potassium-rich foods would exacerbate hyperkalemia. Choice C is incorrect since increasing sodium-rich foods is unrelated to managing hyperkalemia and could potentially lead to other health issues. Choice D is incorrect as decreasing sodium-rich foods is not the primary focus when managing hyperkalemia.

Correct Answer: B

Rationale: The correct answer is B. Avoiding coffee is important in managing peptic ulcer disease as it helps reduce acid production and alleviate symptoms. Coffee is known to stimulate acid secretion in the stomach, which can exacerbate ulcer symptoms. Therefore, instructing the client to avoid drinking coffee is essential in the dietary management of peptic ulcer disease. Choices A, C, and D are incorrect. Drinking milk is generally allowed and can even provide a protective effect against ulcers. High-fiber foods are beneficial for digestion and do not need to be avoided unless they cause discomfort. Low-fat foods are also typically recommended for individuals with peptic ulcer disease as they are easier on the digestive system.

Correct Answer: A

Rationale: The initial step in caring for a client at risk for falls is to conduct a fall-risk assessment. This assessment helps the nurse gather crucial data to identify specific risks and individualized needs, guiding subsequent interventions and preventive measures. By completing a thorough assessment, the nurse can develop a targeted plan of care to mitigate fall risk and ensure the client's safety. Placing a fall-risk identification bracelet, providing nonskid footwear, or setting the bed to the lowest position may be important interventions, but these actions should be based on the findings of the fall-risk assessment, making choice A the priority.

Correct Answer: C

Rationale: The correct answer is C: Lentils. Incomplete proteins lack one or more essential amino acids required for protein synthesis in the body. Examples of incomplete proteins include lentils, vegetables, grains, nuts, and seeds. Lentils, a plant-based protein source, are considered incomplete as they do not contain all essential amino acids in sufficient amounts. Choices A, B, and D are incorrect as eggs, soybeans, and yogurt are examples of complete proteins, containing all essential amino acids in the right proportions for the body's needs.
