Nursing Elites

1. A healthcare professional is using an otoscope to inspect the ears of an adult client. Which action does the professional take before inserting the otoscope?

• A. Pulling the pinna up and back
• B. Pulling the pinna down and forward
• C. Tipping the client's head down and toward the examiner
• D. Tipping the client's head down and away from the examiner

Correct answer: A

Rationale: In an adult client, the healthcare professional should pull the pinna up and back before inserting the otoscope. This action helps straighten the S shape of the ear canal, making it easier to insert the otoscope directly and comfortably. Tipping the client's head down and toward or away from the examiner is not the correct action when using an otoscope in an adult. Pulling the pinna down and forward is typically done when examining an infant or a child younger than 3 years old to straighten their ear canal for better visualization.

2. A nurse notes that a client's physical examination record states that the client's eyes moved normally through the six cardinal fields of gaze. The nurse interprets this to mean that which aspect of eye function is normal?

• A. Near vision
• B. Central vision
• C. Peripheral vision
• D. Ocular movements

Correct answer: D

Rationale: The correct answer is 'Ocular movements.' Moving the eyes through the six cardinal fields of gaze evaluates the function of the eye muscles, such as the medial rectus muscle, superior rectus muscle, superior oblique muscle, lateral rectus muscle, inferior rectus muscle, and inferior oblique muscle. Normal movement in these fields indicates proper ocular movements. Near vision is assessed using a handheld vision screener, central vision with a Snellen chart, and peripheral vision through the confrontation test. Therefore, the evaluation of ocular movements through the six cardinal fields of gaze specifically assesses this aspect of eye function. Choices A, B, and C are incorrect as they pertain to different aspects of vision function that are evaluated using distinct assessment methods, not through the six cardinal fields of gaze.

3. The client has an order for 0.45 mg of Diltiazem. The medication vial has a concentration of 3 mg/mL. How many mL of the drug should be administered?

• A. 0.15 mL
• B. 6.6 mL
• C. 1.5 mL
• D. 0.65 Ml

Correct answer: A

Rationale: To calculate the amount of drug to be administered, divide the ordered dose by the concentration of the medication in the vial. In this case, 0.45 mg � 3 mg/mL = 0.15 mL. Therefore, the correct answer is 0.15 mL. Choice B (6.6 mL) is incorrect as it does not result from the correct calculation. Choice C (1.5 mL) is incorrect as it is not the result of dividing the ordered dose by the concentration. Choice D (0.65 mL) is incorrect as it is not the accurate calculation based on the provided information.

4. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

• A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
• B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
• C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
• D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.

Correct answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

5. The client provides information to a pregnant client who is experiencing nausea and vomiting about measures to relieve the discomfort. Which statement by the mother indicates the need for further information?

• A. ''I should eat five or six small meals a day rather than three full meals.''
• B. ''I need to be sure not to drink liquids with my meals.''
• C. ''I should keep dry crackers at my bedside and eat them before I get out of bed in the morning.''
• D. ''I need to avoid eating fried or greasy foods.''

Correct answer: B

Rationale: To alleviate nausea and vomiting, the client should avoid drinking liquids with meals. The client should keep dry crackers at her bedside, avoid fried foods, and eat smaller meals. Additionally, the client should eat dry crackers every 2 hours to prevent an empty stomach and avoid spicy foods and foods with strong odors, such as onion and cabbage. The incorrect choices are: A) Eating five or six small meals a day instead of three full meals is a correct recommendation. C) Keeping dry crackers at her bedside and eating them before getting out of bed in the morning is a helpful suggestion. D) Avoiding fried or greasy foods is a valid advice to alleviate nausea and vomiting.
