Nursing Elites

1. After inserting an NG tube for a client, which of the following assessment findings should the nurse expect to confirm correct tube placement?

• A. An x-ray shows the end of the tube above the pylorus.
• B. The tube is aspirated and contains clear gastric fluid.
• C. The tube is flushed with sterile water without resistance.
• D. The client does not cough or choke during tube insertion.

Correct answer: B

Rationale: Correct placement of an NG tube is confirmed by aspirating gastric fluid, which indicates that the tube is in the stomach. An x-ray can help visualize tube placement, but it alone does not confirm correct placement. Flushing the tube with sterile water without resistance indicates patency but not necessarily correct placement. The absence of coughing or choking does not confirm tube placement and is more related to the client's comfort during the procedure.

2. A client asks a nurse about their Snellen eye test results. The client's visual acuity is 20/30. Which of the following responses should the nurse make?

• A. “Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.”
• B. “Your right eye can see the chart clearly at 20 feet, and your left eye can see the chart clearly at 30 feet.”
• C. “Your eyes see at 30 feet what visually unimpaired eyes see at 20 feet.”
• D. “Your left eye can see the chart clearly at 20 feet, and your right eye can see the chart clearly at 30 feet.”

Correct answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.

3. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

4. A client has been on bed rest for several weeks. Which finding should the nurse identify as the priority during assessment?

• A. Musculoskeletal weakness
• B. Loss of appetite
• C. Increased heart rate during physical activity
• D. Left lower extremity tenderness

Correct answer: D

Rationale: The nurse should prioritize assessing left lower extremity tenderness as it could indicate deep vein thrombosis, a serious condition that requires immediate attention. Musculoskeletal weakness, loss of appetite, and increased heart rate during physical activity are important but not as critical as a potential thrombotic event that could lead to life-threatening complications. Deep vein thrombosis is a common risk for individuals on prolonged bed rest due to reduced mobility and blood stasis.

5. A nurse is evaluating teaching about nutrition with the guardians of an 11-year-old child. Which of the following statements should indicate to the nurse an understanding of the teaching?

• A. “Our child wants to eat as much as we do, but we’re afraid it will lead to becoming overweight.”
• B. “Our child skips lunch sometimes, but we figure it’s okay as long as we eat a healthy breakfast and dinner.”
• C. “We limit fast-food restaurant meals to three times a week now.”
• D. “We reward school achievements with a point system instead of pizza or ice cream.”

Correct answer: D

Rationale: The correct answer is D. Rewarding school achievements with a point system rather than food items like pizza or ice cream is a healthier approach. This choice indicates an understanding of the teaching about nutrition and the importance of not using food as a reward. Choices A, B, and C do not demonstrate a clear understanding of the teaching as they focus on concerns about overeating, skipping meals, and limiting fast-food consumption but do not address the concept of avoiding food rewards for achievements.
