1. What should be included in the therapeutic management of iron deficiency anemia?
- A. Multivitamins
- B. Calcium
- C. Ferrous sulfate
- D. Iodine
Correct answer: C
Rationale: The correct answer is C: Ferrous sulfate. The therapeutic management of iron deficiency anemia should include iron supplementation, specifically with ferrous sulfate. This helps to replenish the body's iron stores. Multivitamins (choice A) may contain iron, but iron supplementation is more direct and effective. Calcium (choice B) and iodine (choice D) are not typically part of the primary treatment for iron deficiency anemia.
2. The client is 4 hours post-operative from a cesarean section and complains of gas pain and bloating. What non-pharmacological intervention can the nurse provide?
- A. Encourage the client to ambulate
- B. Apply a heating pad
- C. Provide a carbonated beverage
- D. Teach relaxation techniques
Correct answer: A
Rationale: The correct answer is to encourage the client to ambulate. Early ambulation helps alleviate gas pain and bloating by promoting gastrointestinal motility and reducing the accumulation of gas in the abdomen. Applying a heating pad may provide comfort for some types of pain but is not specifically effective for gas pain. Providing a carbonated beverage can actually worsen gas pain due to the introduction of more gas into the digestive system. Teaching relaxation techniques may be beneficial for overall comfort but may not directly address the gas pain and bloating experienced post-cesarean section.
3. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?
- A. Serum potassium
- B. Serum calcium
- C. Serum albumin
- D. Serum sodium
Correct answer: C
Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.
4. What is the function of the enzyme lactase in the digestive system?
- A. Breaks down lactose into glucose and galactose
- B. Breaks down proteins into amino acids
- C. Converts starch into maltose
- D. Breaks down fats into fatty acids
Correct answer: A
Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.
5. When planning care for a client with anorexia nervosa, which goal should be prioritized?
- A. The client will establish normal eating patterns.
- B. The client will verbalize feelings about food and weight.
- C. The client will gain a minimum of 2 pounds per week.
- D. The client will achieve normal electrolyte balance.
Correct answer: D
Rationale: The correct answer is D because achieving normal electrolyte balance is critical in clients with anorexia nervosa. Electrolyte imbalances can lead to serious, life-threatening complications such as cardiac arrhythmias and organ failure. While establishing normal eating patterns (choice A) and verbalizing feelings about food and weight (choice B) are important aspects of treatment, addressing electrolyte balance takes precedence due to the immediate risks associated with imbalances. Additionally, setting a weight gain goal of 2 pounds per week (choice C) may not be appropriate initially as rapid refeeding can also lead to electrolyte imbalances and other complications.
