Nursing Elites

1. The LPN needs to determine the client's respiratory rate. What is the best technique to do this?

• A. Tell the client you need to count their respiratory rate.
• B. Subtly watch the client from across the room when they are doing an activity.
• C. Ask the client to sit still for 30 seconds.
• D. Count respirations while pretending to check the client's pulse.

Correct answer: D

Rationale: The best technique to determine a client's respiratory rate is to count respirations while pretending to check the client's pulse. You should not inform the client that you are counting their respirations, as this might lead to a change in their breathing pattern. Pretending to check the pulse allows you to be close to the client without revealing that you are assessing their respiratory rate. Asking the client to sit still may not be as effective, as it may cause them to concentrate on their breathing. Watching from across the room may not provide an accurate assessment of respirations, as they might be difficult to observe.

2. 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.

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. During data collection of a client with suspected carpal tunnel syndrome, a nurse plans to perform the Phalen test. The nurse should ask the client to perform which activity?

• A. Dorsiflex the foot
• B. Plantarflex the foot
• C. Hold the hands back to back while flexing the wrists 90 degrees for 60 seconds
• D. Hyperextend the fingers with the palmar surfaces of the hands touching, holding the position for 60 seconds

Correct answer: C

Rationale: In the Phalen test, the nurse asks the client to hold the hands back to back while flexing the wrists 90 degrees. This position puts pressure on the median nerve, eliciting symptoms in carpal tunnel syndrome. Dorsiflexing or plantarflexing the foot and hyperextending the fingers are not associated with testing for carpal tunnel syndrome. Acute flexion of the wrist for 60 seconds produces no symptoms in the normal hand.

5. 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.
