Exam 4 Psychology
1. What are influences that are unusual events with a major impact on individual lives because they disrupt the expected sequence of the life cycle?
- A. Nonnormative influences
- B. Normative history-graded influence
- C. Normative age-graded influence
- D. Sensitive period
Correct answer: A
Rationale: Nonnormative influences refer to unusual events that have a significant impact on individuals' lives by disrupting the typical life cycle. They are events that are not typical for a specific age or cohort. Normative history-graded influences (choice B) are common influences shared by a specific generation due to historical circumstances. Normative age-graded influences (choice C) are typical events that occur at a particular age for most people. A sensitive period (choice D) is a biologically determined time during which specific experiences have a lasting impact on development.
2. The parents of a 4-month-old infant tell the nurse that they are getting a microwave oven and will be able to heat the baby’s formula faster. What should the nurse recommend?
- A. Heat only 8 oz or more.
- B. Do not heat a plastic bottle in a microwave oven.
- C. Leave the bottle top uncovered to allow heat to escape.
- D. Shake the bottle vigorously for at least 30 seconds after heating.
Correct answer: B
Rationale: Heating formula in a plastic bottle in the microwave can cause uneven heating and release harmful chemicals from the plastic.
3. A nurse is discussing sources of vitamin K with a client. Which food should the nurse recommend?
- A. Fish
- B. Leafy greens
- C. Citrus fruits
- D. Nuts
Correct answer: B
Rationale: Leafy greens are rich in vitamin K, which is important for blood clotting.
4. What evaluation indicates successful progress on the client goal of increasing daily physical activity?
- A. The client reports decreased social interaction
- B. The client reports more nonsteroidal anti-inflammatory drug (NSAID) use
- C. The client reports a fall
- D. The client reports less fatigue walking up stairs
Correct answer: D
Rationale: The correct answer is D because reporting less fatigue when walking up stairs indicates improved physical endurance, showing progress in increasing daily activity. Choices A, B, and C are incorrect because decreased social interaction, increased NSAID use, and experiencing a fall are not indicators of successful progress in increasing daily physical activity.
5. The client on warfarin has an INR of 1.2. What is the nurse’s priority action?
- A. Increase the dose of warfarin
- B. Administer vitamin K
- C. Monitor for signs of bleeding
- D. Hold the next dose and notify the healthcare provider
Correct answer: A
Rationale: The correct answer is to increase the dose of warfarin. An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating that the dose is subtherapeutic. The priority action in this situation is to adjust the dose to achieve the target therapeutic INR range (usually 2-3) to prevent thromboembolic events. Administering vitamin K is not necessary as the INR is low, and there are no signs of bleeding. Monitoring for signs of bleeding is important but not the priority in this case since the INR is subtherapeutic. Holding the next dose and notifying the healthcare provider would delay the intervention needed to adjust the dose and achieve the therapeutic range.
