1. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?

• A. The client can read from 20' what a person with normal vision can read at 30'.
• B. The client can read from 30' what a person with normal vision can read at 20'.
• C. The client can read the entire chart from 30'.
• D. The client can read the chart from 20' with the left eye and from 30' with the right eye.

Correct answer: A

Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.

2. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

• A. Iris
• B. Cornea
• C. Optic disc
• D. Conjunctiva

Correct answer: C

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

3. The client is being discharged with a prescription for an inhaled glucocorticoid for asthma. Which of the following statements indicates additional education is needed prior to discharge?

• A. "I will hold my breath for 10 seconds after each puff."?
• B. "I will wait five minutes after taking this medication and then gargle water."?
• C. "I will wait at least one minute between each puff."?
• D. "I will take this medication daily even if I am not having symptoms."?

Correct answer: B

Rationale: The correct answer is, 'I will wait five minutes after taking this medication and then gargle water.' After using an inhaled glucocorticoid, it is essential to wait for 5 minutes and then gargle water to remove any residue from the mouth, which can reduce the risk of developing thrush, a fungal infection. Choice A is correct as holding the breath for 10 seconds after each puff helps the medication reach deep into the lungs. Choice C is also correct as waiting at least one minute between puffs ensures proper delivery of the medication. Choice D is incorrect because it is important to take the medication daily as prescribed to control asthma symptoms, even if the person is not experiencing any at that moment.

4. An allergic reaction is classified as what type of pharmacological effect?

• A. a therapeutic effect
• B. a side effect
• C. an adverse effect
• D. an incompatibility

Correct answer: C

Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.

5. A nurse is determining the fetal heart rate (FHR) and places the fetoscope on the mother's abdomen to count the FHR. The nurse simultaneously palpates the mother's radial pulse and notes that it is synchronized with the sounds heard through the fetoscope. Which action should the nurse take?

• A. Count the FHR for 60 seconds, ensuring that it is synchronized consistently with the mother's radial pulse.
• B. Move the fetoscope to another area on the mother's abdomen to locate the fetal heart.
• C. Ask the mother to lie still while both the FHR and the radial pulse rate are counted.
• D. Count the FHR for 30 seconds and then count the radial pulse rate of the mother for 30 seconds.

Correct answer: B

Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.
