1. The substance that is most supportive of bones and teeth is:
- A. Hemoglobin
- B. Collagen
- C. Insulin
- D. Pepsin
Correct answer: B
Rationale: Collagen is a key structural protein in bones and teeth, providing support and strength.
2. Which action by the nurse will help prevent ventilator-associated pneumonia (VAP) in a patient on mechanical ventilation?
- A. Provide oral care every 4 hours.
- B. Reposition the patient every 2 hours.
- C. Suction the patient as needed.
- D. Administer antibiotics as prescribed.
Correct answer: A
Rationale: The correct answer is A. Providing oral care every 4 hours helps prevent ventilator-associated pneumonia by reducing the buildup of bacteria in the mouth that can be aspirated into the lungs. Repositioning the patient every 2 hours is important for preventing pressure ulcers but is not directly related to preventing VAP. Suctioning the patient as needed is essential for maintaining airway patency but does not specifically prevent VAP. Administering antibiotics as prescribed is a treatment for infections but does not prevent VAP.
3. A nurse is providing discharge teaching to a client who has a new prescription for warfarin. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will avoid aspirin while taking this medication.
- B. I will increase my intake of green leafy vegetables.
- C. I will take this medication with an antacid.
- D. I should expect mild bruising around my elbows.
Correct answer: A
Rationale: The correct answer is A: "I will avoid aspirin while taking this medication." Clients taking warfarin should avoid aspirin due to the increased risk of bleeding. Choice B is incorrect because increasing the intake of green leafy vegetables high in Vitamin K can interfere with the effects of warfarin. Choice C is incorrect because warfarin should not be taken with antacids as they can decrease its absorption. Choice D is incorrect because mild bruising is a common side effect of warfarin due to its anticoagulant properties.
4. The healthcare provider is assessing an infant brought to the clinic due to diarrhea. The infant is alert but has dry mucous membranes. Which additional assessment data indicates to the healthcare provider that the infant is experiencing an early to moderate stage of dehydration?
- A. Bradycardia
- B. Tachycardia
- C. Increased blood pressure
- D. Normal fontanels
Correct answer: B
Rationale: Tachycardia is a common early sign of dehydration in infants, especially when presenting with dry mucous membranes and diarrhea. The increased heart rate is the body's compensatory mechanism to maintain cardiac output in response to dehydration. Bradycardia, increased blood pressure, and normal fontanels are not typically associated with early to moderate dehydration in infants.
5. Blood cells are produced in the organs of the _______ system.
- A. endocrine
- B. skeletal
- C. superior to
- D. inferior to
Correct answer: superior to
Rationale: Blood cells are produced in the organs of the hematopoietic system. The correct answer is 'superior to' as this refers to the location of the organs responsible for blood cell production, typically bone marrow found in bones such as the vertebrae, ribs, and skull. 'Endocrine' (Choice A) refers to a different system responsible for hormone production. 'Skeletal' (Choice B) relates to bones but not specifically to the production of blood cells. Choices C and D, 'superior to' and 'inferior to,' do not make sense in the context of blood cell production and are incorrect.
