Nursing Elites

1. A nurse is preparing to test cranial nerve I. Which item does the nurse obtain to test this nerve?

• A. Coffee
• B. A tuning fork
• C. A wisp of cotton
• D. An ophthalmoscope

Correct answer: C

Rationale: To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint. Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I. Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve). Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

2. A nurse, monitoring a client in the fourth stage of labor, checks the client's vital signs every 15 minutes. The nurse notes that the client's pulse rate has increased from 70 to 100 beats/min. On the basis of this finding, which priority action should the nurse take?

• A. Continuing to check the client's vital signs every 15 minutes
• B. Notifying the registered nurse immediately
• C. Checking the client's uterine fundus
• D. Documenting the vital signs in the client's medical record

Correct answer: C

Rationale: During the fourth stage of labor, the woman's vital signs should be assessed every 15 minutes during the first hour. An increasing pulse rate is an early sign of excessive blood loss, as the heart beats faster to compensate for reduced blood volume. The blood pressure decreases as blood volume diminishes, but this is a later sign of hypovolemia. The most common reason for excessive postpartum bleeding is a uterus that is not firmly contracting and compressing open vessels at the placental site. Therefore, the nurse should check the client's uterine fundus for firmness, height, and positioning. Checking the uterine fundus is the priority action as it helps determine if the client is bleeding excessively. Notifying the registered nurse immediately is not necessary unless the cause of bleeding is unclear and needs further intervention. Continuing to check vital signs without addressing the potential issue will delay necessary intervention. Documenting findings is important, but not the immediate priority when faced with a potential emergency situation like postpartum hemorrhage.

3. The LPN is about to give 100 mg Lopressor (metoprolol) to a client. Before administering the drug, they take the patient's vitals, which are as follows: Pulse: 58 Blood Pressure: 90/62 Respirations: 18/minute What action should the LPN take?

• A. Give the client half the prescribed dose and report the findings to the RN on duty.
• B. Give the client double the dose and report the findings to the RN on duty.
• C. Administer the drug and report the findings to the RN on duty.
• D. Hold the drug and report the findings to the RN on duty.

Correct answer: D

Rationale: Lopressor is given to treat hypertension, and a pulse of 58 and a blood pressure of 90/62 are considered low. To prevent the client from bottoming out, the drug should be held, and the findings reported to the RN, who should consult with the attending physician. LPNs should never adjust client dosing, as that is outside of their scope of practice. It is crucial to follow facility guidelines, which often recommend holding blood pressure medication at 60 bpm and a systolic pressure of 90 or less. By holding the drug and notifying the RN, the LPN ensures the client's safety and allows for appropriate assessment and decision-making by the healthcare team. Giving half the dose or double the dose without proper authorization can lead to serious complications and is considered unsafe practice.

4. The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?

• A. 6
• B. 8
• C. 12
• D. 16

Correct answer: C

Rationale: An 18-month-old child should have approximately 12 teeth. In general, children begin dentition around 6 months of age. During the first 2 years of life, a quick guide to the number of teeth a child should have is as follows: Subtract the number 6 from the number of months in the age of the child. In this example, the child is 18 months old, so the formula is 18 - 6 = 12. The correct answer is 12. Choice A (6) is incorrect as it does not consider the child's age. Choices B (8) and D (16) are incorrect as they do not align with the dental development timeline and the specific age of the child in question.

5. A nurse assisting with data collection of the peripheral vascular system performs the Allen test. The nurse understands that this test is used to determine the patency of which blood vessel(s)?

• A. Capillaries
• B. Pedal pulses
• C. Femoral arteries
• D. Radial and ulnar arteries

Correct answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.
