1. Which of the following factors increases the risk of developing a pressure ulcer?
- A. High-protein diet
- B. Frequent repositioning
- C. Immobility
- D. Active range of motion exercises
Correct answer: C
Rationale: Immobility is a significant risk factor for pressure ulcers because it leads to prolonged pressure on specific areas of the body, reducing blood flow and leading to tissue breakdown. Choices A, B, and D are incorrect. A high-protein diet can actually aid in wound healing and tissue repair. Frequent repositioning helps relieve pressure on bony prominences, reducing the risk of pressure ulcers. Active range of motion exercises can improve circulation and prevent muscle atrophy, thereby reducing the risk of pressure ulcers.
2. Who is credited with the stages of cognitive development?
- A. Erikson
- B. Piaget
- C. Freud
- D. Lister
Correct answer: B
Rationale: Piaget is indeed credited with the stages of cognitive development. Jean Piaget, a renowned psychologist, proposed a theory of cognitive development that outlines distinct stages through which children develop intellectually. Erikson, Freud, and Lister are not associated with the stages of cognitive development. Erikson is known for his psychosocial stages, Freud for psychosexual stages, and Lister for contributions to the field of medicine.
3. A 13-year-old girl, diagnosed with diabetes mellitus Type 1 at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?
- A. Ate an extra peanut butter sandwich before gym class
- B. Incorrectly drew up and administered too much insulin
- C. Was not hungry, so she skipped eating lunch
- D. Has had a cold and ear infection for the past two days
Correct answer: B
Rationale: The correct answer is B. Incorrect insulin administration is a common cause of diabetic ketoacidosis. Administering too much insulin can lead to uncontrolled hyperglycemia, where the body starts breaking down fat for energy, resulting in the production of ketones. Choices A, C, and D are less likely to directly cause diabetic ketoacidosis. Eating an extra peanut butter sandwich, skipping lunch, or having a cold and ear infection would not directly lead to the metabolic derangements seen in diabetic ketoacidosis.
4. A parent receives a note from the school that a student in class has head lice. The parent calls the school nurse to ask how to check for head lice. What instructions should the nurse provide?
- A. Ask the child where it itches.
- B. Check to see if your dog has ear mites.
- C. Look along the scalp line for white dots.
- D. Observe between the fingers for red lines.
Correct answer: C
Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots/nits are the eggs of head lice and are commonly found attached to the hair shaft near the scalp. This method helps identify if head lice are present. Choice A is incorrect as itching alone may not be a definitive sign of head lice; it could be due to other reasons. Choice B is irrelevant as ear mites in dogs are not related to head lice infestation in humans. Choice D is also incorrect as observing between the fingers for red lines is not a method for checking head lice.
5. During a client admission, how should the nurse conduct medication reconciliation?
- A. Compare the client’s home medications to the provider's prescriptions.
- B. Review the client’s medical history.
- C. Assess the client's current medications.
- D. Ask the client about their allergies.
Correct answer: A
Rationale: During medication reconciliation, the nurse should compare the client’s home medications with the provider's prescriptions to ensure accuracy and prevent medication errors. Reviewing the client’s medical history (Choice B) is important but not the primary focus of medication reconciliation. Assessing the client's current medications (Choice C) is also vital but is not specific to the comparison between home and prescribed medications during reconciliation. Asking the client about their allergies (Choice D) is relevant for ensuring safe medication administration but is not the primary step in medication reconciliation, which involves comparing actual medications.
