Nursing Elites

1. Identify the placement of the stapes footplate into the bony labyrinth.

• A. Fenestra vestibuli
• B. Fenestra cochleae
• C. Tympanic membrane
• D. Round window

Correct answer: A

Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.

2. A 60-year-old male with type 2 diabetes mellitus tells the nurse that he is going to join a gym and start working out. Which information is most important for the nurse to obtain?

• A. Recent serum cholesterol levels
• B. Presence of calf pain during exercise
• C. Average weight gain or loss in the last year
• D. Exercise tolerance test with EKG results

Correct answer: B

Rationale: The most important information for the nurse to obtain in this scenario is the presence of calf pain during exercise. Calf pain during exercise could indicate peripheral vascular issues, such as peripheral artery disease, which is crucial to address before starting an exercise program. High cholesterol levels (choice A) may be important but are not as immediately relevant as assessing for peripheral vascular issues. Average weight gain or loss (choice C) may provide some insight into the patient's overall health status but is not as critical as assessing for potential vascular complications. An exercise tolerance test with EKG results (choice D) may be valuable in assessing cardiovascular fitness but is not as crucial as evaluating for peripheral vascular issues given the patient's symptoms.

3. The healthcare provider prescribed furosemide for a 4-year-old child with a ventricular septal defect. Which outcome indicates to the nurse that this pharmacological intervention was effective?

• A. Urine specific gravity changing from 1.021 to 1.031
• B. Daily weight decrease of 2 pounds (0.9 kg)
• C. Blood urea nitrogen (BUN) increasing from 8 to 12 mg/dl (2.9 to 4.3)
• D. Urinary output decreasing by 5 ml/hour

Correct answer: B

Rationale: The correct answer is B. A daily weight decrease of 2 pounds (0.9 kg) is the most appropriate outcome to indicate the effectiveness of furosemide in a child with a ventricular septal defect. Furosemide is a diuretic medication that helps reduce fluid retention. Therefore, a decrease in weight reflects a reduction in fluid volume, which is the desired effect of furosemide. Choices A, C, and D are incorrect because changes in urine specific gravity, blood urea nitrogen (BUN) levels, and urinary output do not directly reflect the effectiveness of furosemide in this context.

4. A client is admitted to the labor and delivery unit in early labor, and the nurse assesses the status of her contractions. The frequency of contractions is most accurately evaluated by counting the minutes and seconds in which manner?

• A. From the peak of one contraction to the peak of the next contraction
• B. From the beginning of one contraction to the end of that contraction
• C. From the beginning of one contraction to the beginning of the next contraction
• D. From the end of one contraction to the beginning of the next contraction

Correct answer: C

Rationale: The frequency of contractions is measured from the beginning of one contraction to the beginning of the next contraction. This timing is crucial in determining the progress of labor. Choice A, measuring from peak to peak, is incorrect as it assesses the duration between the highest points of contractions, which is not how frequency is calculated. Choice B, measuring from the beginning to the end of one contraction, is incorrect as it does not consider the start of the next contraction. Choice D, measuring from the end of one contraction to the beginning of the next contraction, is incorrect as it misses the initial onset of the following contraction.

5. The nurse is planning care for a client admitted with a diagnosis of pheochromocytoma. Which intervention has the highest priority for inclusion in this client’s plan of care?

• A. Record urine output every hour
• B. Monitor blood pressure frequently
• C. Evaluate neurological status
• D. Maintain seizure precautions

Correct answer: B

Rationale: Pheochromocytoma is associated with severe hypertension due to excessive catecholamine release. Monitoring blood pressure frequently is the priority intervention to assess for hypertensive crises and prevent complications like stroke, heart attack, or organ damage. While recording urine output every hour, evaluating neurological status, and maintaining seizure precautions are important aspects of care, they are not the highest priority in a client with pheochromocytoma.
