1. What is the most important function of carbohydrates?
- A. Store and provide energy for the body
- B. Create amino acids
- C. Maintain body temperature
- D. Insulate body organs against shock
Correct answer: A
Rationale: The most important function of carbohydrates is to store and provide energy for the body through metabolic processes. Carbohydrates are broken down into glucose, which is used as the primary source of energy for various cellular functions. Choice B is incorrect because amino acids are the building blocks of proteins, not directly created by carbohydrates. Choice C is incorrect as the regulation of body temperature is primarily controlled by mechanisms such as sweating and shivering, not carbohydrates. Choice D is incorrect as insulation of body organs against shock is mainly provided by adipose tissue, not carbohydrates.
2. A client in the third trimester of pregnancy reports that she feels some 'lumpy places' in her breasts and that her nipples sometimes leak a yellowish fluid. She has an appointment with her healthcare provider in two weeks. What action should the nurse take?
- A. Instruct the client to immediately see her provider for an evaluation
- B. Assess the fluid for signs of infection
- C. Explain that this normal secretion can be assessed at the next visit
- D. Recommend breast ultrasound to rule out abnormalities
Correct answer: C
Rationale: The yellowish fluid is likely colostrum, a normal finding in late pregnancy as the breasts prepare for lactation. It is common for women in the third trimester to experience 'lumpy places' in the breasts due to increased milk duct development. In this situation, the nurse should educate the client that these findings are normal physiological changes associated with pregnancy. Since the client has an upcoming appointment with her healthcare provider in two weeks, it is appropriate to reassure her that this can be further assessed during that visit. Instructing the client to immediately see her provider (Choice A) is unnecessary as this is a common finding in late pregnancy. Assessing the fluid for signs of infection (Choice B) is not warranted as colostrum leakage is a normal occurrence. Recommending a breast ultrasound (Choice D) is premature without further assessment by the healthcare provider.
3. A client with peptic ulcer disease is being taught about lifestyle modifications by a nurse. Which client statement indicates a need for further teaching?
- A. ‘I should avoid drinking alcohol to prevent irritation of my ulcer.’
- B. ‘I should take my antacids regularly, even if I don’t have symptoms.’
- C. ‘I should avoid eating spicy foods to prevent irritation of my ulcer.’
- D. ‘I should limit my caffeine intake to prevent irritation of my ulcer.’
Correct answer: B
Rationale: The statement ‘I should take my antacids regularly, even if I don’t have symptoms’ indicates a misunderstanding. Antacids should only be taken when symptoms are present to neutralize excess stomach acid. Taking antacids regularly when not experiencing symptoms may lead to metabolic alkalosis. Choices A, C, and D are correct statements for a client with peptic ulcer disease as they all focus on avoiding irritants that can exacerbate the condition.
4. A parent asks the school nurse how to eliminate lice from their child. What is the most appropriate response by the nurse?
- A. Cut the child's hair short to remove the nits
- B. Apply warm soaks to the head twice daily
- C. Wash the child's linen and clothing in a bleach solution
- D. Application of pediculicides
Correct answer: D
Rationale: Pediculicides are the recommended treatment for lice and should be used to eliminate the infestation.
5. A client who is admitted to the mental health unit reports shortness of breath and dizziness. The client tells the nurse, “I feel like I’m going to die.” Which nursing problem should the nurse include in this client’s plan of care?
- A. Mood disturbance
- B. Moderate anxiety
- C. Altered thoughts
- D. Social isolation
Correct answer: B
Rationale: The correct answer is B: Moderate anxiety. When a client presents with symptoms such as shortness of breath, dizziness, and a fear of dying, it indicates moderate anxiety. Anxiety can manifest physically with symptoms like these. Mood disturbance (choice A) refers to a change in mood, while altered thoughts (choice C) relate to cognitive changes. Social isolation (choice D) involves a lack of social interaction, which is not the primary concern in this scenario where the client is experiencing acute anxiety symptoms.
