Nursing Elites

1. A healthcare professional is planning to obtain the vital signs of a 2-year-old child who is experiencing diarrhea and who might have a right ear infection. Which of the following routes should the healthcare professional use to obtain the temperature?

• A. Temporal
• B. Oral
• C. Rectal
• D. Axillary

Correct answer: C

Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.

2. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 1,000-mL IV to infuse over 10 hr. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)

• A. 100 mL/hr
• B. 150 mL/hr
• C. 75 mL/hr
• D. 50 mL/hr

Correct answer: A

Rationale: To infuse 1,000 mL over 10 hr, the IV pump should be set to deliver 100 mL/hr. This calculation is derived by dividing the total volume (1,000 mL) by the total time in hours (10 hr), resulting in the infusion rate of 100 mL/hr. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation for this scenario.

3. A client is recovering from gallbladder surgery performed under general anesthesia. How many times per hour should the nurse encourage the client to use the incentive spirometer?

• A. 4-5 times per hour
• B. 2-3 times per hour
• C. 6-7 times per hour
• D. 8-10 times per hour

Correct answer: A

Rationale: Encouraging the client to use the incentive spirometer 4-5 times per hour is the correct approach post-gallbladder surgery under general anesthesia. This frequency helps prevent respiratory complications, such as atelectasis, by promoting lung expansion. Choices B, C, and D suggest either too few or too many sessions per hour, which may not be optimal for the client's respiratory recovery needs. It is important to strike a balance between ensuring adequate lung expansion and not overexerting the client, which is why 4-5 times per hour is the recommended frequency.

4. A healthcare professional is preparing to administer gentamicin 2 mg/kg via IV bolus to a client who weighs 220 lb. How many mg should the healthcare professional administer?

• A. 200 mg
• B. 100 mg
• C. 160 mg
• D. 180 mg

Correct answer: C

Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg × 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.

5. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?

• A. 1/2 tablet.
• B. 1 tablet.
• C. 1 1/2 tablets.
• D. 2 tablets.

Correct answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.
