1. What is the proper technique for obtaining a blood specimen from a central venous line?
- A. Use sterile gloves and discard the first 10 mL of blood
- B. Flush the line with heparin and then draw the specimen
- C. Draw the specimen and then administer heparin
- D. Use non-sterile gloves to reduce contamination risk
Correct answer: A
Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.
2. How are lipids carried in the bloodstream?
- A. Micelles.
- B. Glycolipids.
- C. Lecithin.
- D. Lipoproteins.
Correct answer: D
Rationale: Lipids are carried in the bloodstream in the form of lipoproteins. Lipoproteins are complexes of proteins and lipids that transport fats to various parts of the body. While micelles, glycolipids, and lecithin are all related to lipid metabolism, they are not the primary carriers of lipids in the bloodstream. Micelles are small lipid clusters in the intestines, glycolipids are lipids with a carbohydrate attached, and lecithin is a type of phospholipid. Therefore, lipoproteins are the correct answer as they are specifically designed for transporting lipids through the bloodstream.
3. The nurse is making a home visit with a client diagnosed with Alzheimer's disease. The client recently started on lorazepam (Ativan) due to increased anxiety. The nurse is cautioning the family about the use of lorazepam (Ativan). The nurse should instruct the family to report which of the following significant side effects to the healthcare provider?
- A. Paradoxical excitement
- B. Headache
- C. Slowing of reflexes
- D. Fatigue
Correct answer: A
Rationale: The correct answer is A, paradoxical excitement. Lorazepam can cause an unexpected response of paradoxical excitement, which should be reported to the healthcare provider. This reaction is characterized by increased anxiety, restlessness, and agitation instead of the expected calming effect. Choices B, C, and D are incorrect because headache, slowing of reflexes, and fatigue are more common side effects of lorazepam and may not warrant immediate reporting unless severe or persistent.
4. A nurse is assessing a 1-hour postpartum client and notes a boggy uterus located 2 cm above the umbilicus. Which of the following actions should the nurse take first?
- A. Take vital signs
- B. Assess lochia
- C. Massage the fundus
- D. Give oxytocin IV bolus
Correct answer: C
Rationale: When a nurse assesses a 1-hour postpartum client with a boggy uterus located 2 cm above the umbilicus, it indicates uterine atony. The first action the nurse should take is to massage the fundus. Fundal massage helps stimulate uterine contractions, which will reduce bleeding and prevent postpartum hemorrhage. Taking vital signs, assessing lochia, or administering an oxytocin IV bolus are important interventions but should come after addressing uterine atony through fundal massage.
5. A healthcare professional is preparing to administer a flu vaccine. Which of the following should the healthcare professional verify?
- A. Client's age
- B. Client's allergy to eggs
- C. Client's vaccination history
- D. Client's weight
Correct answer: C
Rationale: The healthcare professional should verify the client's vaccination history to ensure they are due for the flu vaccine. Verifying the client's age (choice A) is important for other vaccines but not specifically for the flu vaccine. While allergy to eggs (choice B) is relevant as the flu vaccine is traditionally produced in eggs, it is not the top priority for verification. The client's weight (choice D) is not directly related to the administration of the flu vaccine.
