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. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

3. When a woman is receiving postpartum epidural morphine, the nurse should plan to observe for which of the following side effects to occur within the first 3 hours?

• A. nausea and vomiting
• B. itching
• C. urinary retention
• D. somnolence

Correct answer: B

Rationale: A side effect of postpartum epidural morphine is the onset of itching within 3 hours of injection and lasting up to 10 hours. Nausea and vomiting might occur 4-7 hours after injection. While urinary retention is a side effect of postpartum epidural morphine, it is not typically assessed within the first 3 hours. Somnolence is a rare side effect and not commonly observed within the first 3 hours. Therefore, itching is the most likely side effect to be observed within the initial 3 hours after administering postpartum epidural morphine.

4. A nurse is preparing to assess the function of a client's spinal accessory nerve. Which action does the nurse ask the client to take to aid assessment of this nerve?

• A. Smiling
• B. Clenching the teeth
• C. Shrugging the shoulders against the nurse's resistance
• D. Identifying by taste a substance placed on the back of the tongue

Correct answer: C

Rationale: To assess cranial nerve XI (spinal accessory nerve), the examiner checks the sternomastoid and trapezius muscles for equal size. Equal strength is assessed by asking the client to rotate the head forcibly against resistance applied to the side of the chin and by asking the client to shrug the shoulders against resistance. These movements should feel equally strong on the two sides. The client is asked to smile as a test of the function of cranial nerve VII (facial nerve). The client's ability to clench the teeth is used to assess the motor function of cranial nerve V (trigeminal nerve). The client's taste perception is used to assess the sensory function of cranial nerve IX (glossopharyngeal nerve). Therefore, the correct action to assess the spinal accessory nerve is to ask the client to shrug the shoulders against resistance. The other options are used to assess different cranial nerves, making them incorrect choices.

5. 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.
