1. The nurse assesses a patient with pernicious anemia. Which assessment finding would the nurse expect?
- A. Yellow-tinged sclerae
- B. Shiny, smooth tongue
- C. Numbness of the extremities
- D. Gum bleeding and tenderness
Correct answer: C
Rationale: The correct answer is C: Numbness of the extremities. Numbness of the extremities is a common finding in patients with pernicious anemia, which is caused by cobalamin (vitamin B12) deficiency. This deficiency affects the peripheral nervous system, leading to neurological symptoms like numbness and tingling in the extremities. Choices A, B, and D are incorrect: Yellow-tinged sclerae is more indicative of jaundice or liver dysfunction, a shiny smooth tongue is seen in conditions like glossitis, and gum bleeding and tenderness are associated with periodontal disease or vitamin C deficiency, not pernicious anemia.
2. A nurse is preparing to administer a gavage feeding via nasogastric tube to a preterm newborn who is receiving supplemental oxygen. Which of the following actions should the nurse take?
- A. Stabilize the tube with tape to the newborn’s forehead.
- B. Remove supplemental oxygen during the feeding.
- C. Measure the stomach aspirate prior to the feeding.
- D. Place the newborn on her left side for 30 min after the feeding.
Correct answer: C
Rationale: Measuring the stomach aspirate prior to the feeding is essential to ensure proper placement and function of the NG tube.
3. By using which method of assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups?
- A. sequential
- B. random
- C. systematic
- D. correlational
Correct answer: B
Rationale: By using random assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups. Random assignment helps reduce the likelihood of bias in the selection process and ensures that any differences between groups are due to the treatment and not pre-existing group differences. Sequential, systematic, and correlational assignment methods do not provide the same level of assurance in distributing participants' characteristics equally across treatment groups.
4. Which of the following best describes epidemiology?
- A. The study of the distribution and determinants of health-related states or events in specified populations.
- B. The study of the distribution and determinants of health-related states or events in specified populations and the application of this study to control health problems.
- C. The study of how social factors influence health outcomes.
- D. The study of how health systems and services impact population health.
Correct answer: B
Rationale: Epidemiology is defined as the study of the distribution and determinants of health-related states or events in specified populations, as well as the application of this study to control health problems. This field focuses on identifying patterns and causes of health and disease in order to develop strategies for prevention and control.
5. The nurse is assessing a child's capillary refill time. This can be accomplished by doing what?
- A. Inspect the chest
- B. Auscultate the heart
- C. Palpate the apical pulse
- D. Palpate the nail bed with pressure to produce a slight blanching
Correct answer: D
Rationale: Capillary refill time is assessed by applying pressure to the nail bed and observing how quickly the color returns, indicating peripheral circulation status.
