1. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?
- A. Assessing visual acuity
- B. Inspecting the eyelids for ptosis
- C. Assessing pupil constriction
- D. Assessing ocular movements
Correct answer: A
Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.
2. How often should a 5-year-old child undergo a dental examination?
- A. Every 6 months
- B. Whenever a new primary tooth erupts
- C. Once a year
- D. Every 3 months
Correct answer: A
Rationale: For a 5-year-old child, dental examinations should be conducted every 6 months. This frequency allows for early detection of dental issues and promotes good oral health. Choices B, C, and D are incorrect because waiting for a new primary tooth to erupt, having an examination once a year, or every 3 months are not the recommended intervals for dental check-ups in this age group. It is essential to adhere to the standard guideline of every 6 months to ensure regular monitoring and preventive care for the child's dental health.
3. A nurse notes the presence of variable decelerations on the fetal heart rate monitor strip and suspects cord compression. The nurse should immediately perform which action?
- A. Insert a gloved finger into the mother's vagina to feel for cord compression
- B. Position the mother so that her hips are elevated
- C. Notify the registered nurse
- D. Perform a vaginal examination on the mother
Correct answer: B
Rationale: When variable decelerations on the fetal heart rate monitor strip suggest cord compression, the immediate action the nurse should take is to reposition the mother to alleviate the compression. Elevating the mother's hips or changing her position can help shift the fetal presenting part and relieve pressure on the cord. This action aims to improve or resolve the variable decelerations. Contacting the registered nurse may be necessary, but it is not the immediate action required in this situation. Performing a vaginal examination is contraindicated due to the potential risk of further compromising blood flow through the umbilical cord. Inserting a gloved finger into the mother's vagina to feel for the cord is also not recommended as it poses a similar risk of exacerbating the situation.
4. What is a chemical reaction between drugs before their administration or absorption known as?
- A. a drug incompatibility
- B. a side effect
- C. an adverse event
- D. an allergic response
Correct answer: A
Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly occurs when drug solutions are mixed before intravenous administration but can also happen with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses typically occur after the drugs have been administered and absorbed, not before.
5. The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?
- A. 6
- B. 8
- C. 12
- D. 16
Correct answer: C
Rationale: An 18-month-old child should have approximately 12 teeth. In general, children begin dentition around 6 months of age. During the first 2 years of life, a quick guide to the number of teeth a child should have is as follows: Subtract the number 6 from the number of months in the age of the child. In this example, the child is 18 months old, so the formula is 18 - 6 = 12. The correct answer is 12. Choice A (6) is incorrect as it does not consider the child's age. Choices B (8) and D (16) are incorrect as they do not align with the dental development timeline and the specific age of the child in question.
