Nursing Elites

1. Immediately after delivery, the nurse assesses the woman's uterine fundus. At what location does the nurse expect to be able to palpate the fundus?

• A. At the level of the umbilicus
• B. Two centimeters above the umbilicus
• C. Midway between the symphysis pubis and umbilicus
• D. In the pelvic cavity

Correct answer: C

Rationale: The correct answer is midway between the symphysis pubis and the umbilicus. Immediately after delivery, the uterus is about the size of a large grapefruit or softball. The fundus can be palpated at this location but then rises to a level just above the umbilicus before sinking to the level of the umbilicus, where it remains for about 24 hours. After 24 hours, the fundus starts descending gradually. By the 10th to 14th day, the fundus is in the pelvic cavity and cannot be palpated abdominally. Choices A and B are incorrect as the fundus is not initially at the level of the umbilicus or 2 centimeters above it. Choice D is also incorrect as the fundus does not remain in the pelvic cavity immediately after delivery.

2. While assisting with data collection regarding the neurological system, the nurse asks the client to puff out both cheeks. Which cranial nerve is the nurse assessing?

• A. Vagus
• B. Facial
• C. Abducens
• D. Oculomotor

Correct answer: B

Rationale: The correct answer is B: Facial. Assessment of cranial nerve VII (facial nerve) involves noting mobility and symmetry as the client performs various facial movements, including puffing out the cheeks. Cranial nerve IX (glossopharyngeal nerve) and cranial nerve X (vagus nerve) are tested together for different functions. The abducens, oculomotor, and trochlear nerves are assessed together for eye movements and pupil reactions, not cheek puffing.

3. What is the primary nutritional deficiency of concern for a strict vegetarian?

• A. vitamin C
• B. vitamin B12
• C. vitamin E
• D. magnesium

Correct answer: B

Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.

4. Which of these medications is least likely to cause tinnitus?

• A. Aspirin
• B. Lasix
• C. Gentamicin
• D. Fluoxetine

Correct answer: D

Rationale: The correct answer is Fluoxetine. Among the options provided, Fluoxetine is the medication least likely to cause tinnitus. Gentamicin, Lasix, and Aspirin are known ototoxic medications that have a potential side effect of causing tinnitus, a ringing in the ear. Gentamicin is an antibiotic, Lasix is a diuretic, and Aspirin is a common pain reliever that can lead to tinnitus. In contrast, Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) primarily used as an antidepressant, and it has a lower risk of causing tinnitus compared to the other options.

5. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?

• A. The fingers curl tightly, and the toes curl forward.
• B. The toes flare, and the big toe is dorsiflexed.
• C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
• D. The infant turns to the side that is touched.

Correct answer: B

Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.
