Nursing Elites

1. While assisting with data collection, the nurse asks the client to close their jaws tightly. Subsequently, the nurse tries to open the closed jaws. In this technique, the nurse is assessing the motor function of which nerve?

• A. Trochlear nerve
• B. Abducens nerve
• C. Trigeminal nerve
• D. Oculomotor nerve

Correct answer: C

Rationale: The correct answer is C: Trigeminal nerve. To test the motor function of the trigeminal nerve (cranial nerve V), the nurse assesses the muscles of mastication by asking the client to clench their teeth. By trying to separate the client's jaws, the nurse evaluates the strength of the temporal and masseter muscles innervated by the trigeminal nerve. This technique helps assess if the trigeminal nerve is functioning properly. Choices A, B, and D are incorrect because they relate to other cranial nerves that are not involved in the specific motor function being tested in this scenario. These nerves are usually assessed through different examinations such as assessing the pupils and extraocular movements, which are not part of the jaw clenching and opening technique described in the question.

2. While taking the vital signs of a pregnant client admitted to the labor unit, a nurse notes a temperature of 100.6�F, pulse rate of 100 beats/min, and respirations of 24 breaths/min. What is the most appropriate nursing action based on these findings?

• A. Notify the registered nurse of the findings.
• B. Document the findings in the client's medical record.
• C. Recheck the vital signs in 1 hour.
• D. Continue collecting subjective and objective data.

Correct answer: A

Rationale: The correct answer is to notify the registered nurse of the findings. In a pregnant client, the normal temperature range is 98�F to 99.6�F, with a pulse rate of 60 to 90 beats/min and respirations of 12 to 20 breaths/min. A temperature of 100.4�F or higher, along with an increased pulse rate and faster respirations, suggests a possible infection. Immediate notification of the registered nurse is crucial for further evaluation and intervention. While documenting the findings is essential, the priority lies in promptly escalating abnormal vital signs for assessment and management. Rechecking vital signs in 1 hour may delay necessary interventions for a deteriorating condition. Continuing to collect data is relevant but should not delay informing the registered nurse when abnormal vital signs are present.

3. 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.

4. 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.

5. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.
