Question 1 of 5
A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?
Correct Answer: D
Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20.
Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.
Choice A is incorrect because 20/80 does not meet the criteria for legal blindness.
Choice B is incorrect as the client's vision is impaired.
Choice C is incorrect because it reverses the interpretation of the fraction.
Question 2 of 5
A nurse working in a pediatric clinic and observes the following situations. Which of the following may indicate a delayed child to the nurse?
Correct Answer: A
Rationale: At 12 months a child should at least be 'cruising' (holding on to objects to walk).
Question 3 of 5
A client describes her cervical mucus as clear, thin, and elastic. Upon examination, the nurse demonstrates that the cervical mucus can be stretched 8-10 cm. The nurse correctly documents the finding as:
Correct Answer: C
Rationale: The nurse should document the finding as 'spinnbarkheit.' Spinnbarkheit is the term used to describe the clear, thin, and elastic cervical mucus that can be stretched 8-10 cm, indicating ovulation. It helps couples determine the most fertile period for conception. Ferning capacity or crystallization increases as ovulation approaches, but it requires microscopic examination to be confirmed. Lack of ferning cannot be determined without such examination. 'Inhospitable' cervical mucus refers to patterns that prohibit sperm motility, caused by various factors like hormone levels or infection. These conditions cannot be assessed based solely on the description provided in the question.
Question 4 of 5
A mother brings her 1-year-old child to the clinic. The child has no record of previous immunizations, and the mother confirms the child has not been immunized. Teaching by the nurse should include which of the following?
Correct Answer: A
Rationale: The correct answer is 'Immunizations may be started at any age.' While there is a recommended immunization schedule, immunizations can be initiated at any age. It is essential to emphasize the flexibility in starting immunizations. The statement 'The recommended immunization schedule should be followed' is too rigid; while recommended, there is flexibility in initiation.
Choice C is correct as an interrupted series can be continued without restarting. The statement 'Delaying the start of vaccines does not increase the risk of reaction' is correct. Delaying does not increase the risk of reaction; in fact, it is important to start immunizations to protect the child and the community.
Question 5 of 5
An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?
Correct Answer: C
Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate.
Therefore, a cardiac output of 5 L/min is considered normal.
Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information.
Choice D is unrelated to the client's cardiac output and thus incorrect.
