LPN Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is A: 'I should increase my intake of foods high in iron.' Iron-deficiency anemia is managed by increasing the consumption of iron-rich foods to improve iron levels in the body. Foods high in iron include red meat, poultry, fish, beans, lentils, and iron-fortified cereals. Choices B, C, and D are incorrect because decreasing intake of iron-rich foods or increasing intake of calcium-rich foods would not address the deficiency in iron levels that characterizes iron-deficiency anemia.

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: C

Rationale: For infants and young children, the vastus lateralis muscle located over the anterior thigh is the preferred site for intramuscular injections. This site is chosen for its large muscle mass and reduced risk of injury to major nerves and blood vessels. Infants have less developed muscle structures, making the vastus lateralis a safer and more effective site for injections compared to other sites like the deltoid, ventrogluteal, or dorsogluteal. Using the correct injection site is essential to prevent complications and ensure the proper absorption of the medication.

Correct Answer: C

Rationale: In acute renal failure, the kidneys are unable to excrete potassium efficiently, which can lead to hyperkalemia. As a result, an increased potassium level is a common finding in clients with acute renal failure. Hyperkalemia can have serious cardiac effects, making it essential for healthcare providers to monitor and manage potassium levels closely in clients with renal impairment. Choices A, B, and D are incorrect because in acute renal failure, blood urea nitrogen (BUN) and creatinine levels typically rise due to decreased renal function. Calcium levels are more likely to be decreased in acute renal failure due to impaired activation of vitamin D and subsequent decreased calcium absorption.

Correct Answer: B

Rationale: The correct answer is B. In hyperlipidemia management, decreasing the intake of foods high in cholesterol is crucial to improve lipid levels and reduce the risk of cardiovascular diseases. Choices A and C are incorrect as increasing intake of saturated fats or trans fats can raise cholesterol levels, worsening the condition. Choice D is incorrect because decreasing intake of foods high in fiber is not recommended as fiber-rich foods are beneficial for heart health, which is important in managing hyperlipidemia.
