Nursing Elites

1. In conducting a health screening for 12-month-old children, the nurse expects them to have been immunized against which of the following diseases?

• A. measles, polio, pertussis, hepatitis B
• B. diphtheria, pertussis, polio, tetanus
• C. rubella, polio, pertussis, hepatitis A
• D. measles, mumps, rubella, polio

Correct answer: B

Rationale: By 12 months of age, children should have received the DTaP (diphtheria, pertussis, and tetanus) vaccine along with the polio vaccine. The MMR (measles, mumps, and rubella) vaccine is not typically given until the child is 12-15 months old. Therefore, option B is correct as it includes vaccines that are usually administered by 12 months of age. Options A, C, and D are incorrect as they include vaccines that are typically given after 12 months of age.

2. A nurse assisting with data collection is preparing to auscultate the client's bowel sounds. The client tells the nurse that he ate lunch just 45 minutes ago. On the basis of this information, which finding does the nurse expect to note?

• A. Gurgling sounds
• B. Hypoactive sounds
• C. Low-pitched sounds
• D. An absence of sounds

Correct answer: A

Rationale: Bowel sounds are high-pitched, gurgling, cascading sounds that occur irregularly between five and 30 times a minute. In this scenario, since the client ate lunch just 45 minutes ago, the nurse would expect to note gurgling sounds as normal bowel activity. Hypoactive sounds (low-pitched) or an absence of sounds are usually associated with conditions such as abdominal surgery or inflammation of the peritoneum, not with recent food intake. Therefore, the correct answer is gurgling sounds, indicating normal bowel activity following a recent meal.

3. The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus� (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ____ units for administration.

• A. 12
• B. 35
• C. 16
• D. 9

Correct answer: B

Rationale: To calculate the correct dosage, first convert the client's weight from pounds to kilograms. As 1 kg = 2.2 pounds, 176 pounds � 2.2 = 80 kg. The client should receive 0.2 units for every kilogram, which equals 16 units. Therefore, the total amount to prepare is 16 units x 100 units/mL = 1600 units. Considering the medication concentration of 100 units/mL, 1600 units � 100 units/mL = 16 mL. However, since the question asks for the number of units, the final answer is 16 units x 2 injections = 32 units. Therefore, the LPN should prepare 32 units for administration.

4. A nurse is preparing to assess the fetal heart rate (FHR) of a client who is 14 weeks pregnant. Which piece of equipment does the nurse use to assess the FHR?

• A. Stethoscope
• B. Doppler transducer
• C. Fetoscope
• D. Pulse oximetry on the client and a fetoscope

Correct answer: B

Rationale: To assess the fetal heart rate of a client who is 14 weeks pregnant, the nurse should use a Doppler transducer. Fetal heart sounds can be heard with a fetoscope by 20 weeks of gestation. The Doppler transducer amplifies fetal heart sounds so that they are audible by 10 to 12 weeks of gestation, making it the most appropriate choice for this scenario. Fetal heart sounds cannot be heard with a stethoscope. Pulse oximetry is not used to auscultate fetal heart sounds, so it is an incorrect choice in this context.

5. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part water and one part concentrate.
• D. When using powdered formula, mix two parts water and one part powder.

Correct answer: A

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.
