This limitation of longitudinal research is known as __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 34 Test Bank for Berk, Development Through the Lifespan, 7e
- A. biased sampling
- B. practice effects
- C. random assignment
- D. cohort effects Answer: B Page Ref: 35 Skill Level: Apply Topic: Studying Development Difficulty Level: Moderate
Correct answer: B
Rationale: Practice effects refer to the phenomenon where participants in a longitudinal study show improvement in test performance over time due to becoming familiar with the tasks or test materials. This can be considered a limitation as it may distort the results by showing an artificial improvement rather than a true developmental change.
2. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.
- A. 4%
- B. 21%
- C. 34%
- D. 49%
Correct answer: B
Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.
3. A client has a new ileostomy. Which of the following actions should the nurse take?
- A. Apply a skin barrier around the stoma.
- B. Empty the pouch when it is one-third full.
- C. Change the entire pouching system weekly.
- D. Cleanse the peristomal skin with alcohol.
Correct answer: C
Rationale: Changing the entire pouching system weekly is essential for maintaining skin integrity and preventing infection. Option A is incorrect as applying a skin barrier should be done during the pouch change, not separately. Option B is incorrect as ileostomy pouches should be emptied when they are one-third to one-half full to prevent leakage. Option D is incorrect because cleansing the peristomal skin with alcohol can be too harsh and may cause skin irritation.
4. During the third stage of labor, __________.
- A. the cervix thins to nothing
- B. uterine contractions begin
- C. the placenta is delivered
- D. the baby is born
Correct answer: C
Rationale: During the third stage of labor, the correct answer is C, the placenta is delivered. This stage occurs after the baby is born and involves the expulsion of the placenta from the uterus. Choice A is incorrect because the thinning of the cervix to nothing typically occurs during the first stage of labor. Choice B is incorrect as uterine contractions usually begin during the first stage of labor to help with the dilation of the cervix. Choice D is incorrect because the baby is typically born in the second stage of labor, not the third.
5. The client on warfarin has an INR of 5.5. What is the priority nursing action?
- A. Administer vitamin K as an antidote.
- B. Hold the next dose of warfarin.
- C. Increase the dose of warfarin.
- D. Administer fresh frozen plasma.
Correct answer: A
Rationale: An INR of 5.5 is significantly elevated, indicating an increased risk of bleeding. The priority nursing action in this situation is to administer vitamin K as an antidote to reverse the effects of warfarin and lower the INR. Holding the next dose of warfarin (choice B) is important but not as immediate as administering vitamin K. Increasing the dose of warfarin (choice C) would further elevate the INR, worsening the bleeding risk. Administering fresh frozen plasma (choice D) is not the first-line treatment for high INR due to warfarin.
