Nursing Elites

1. Which nutritional assessment data should be collected to best reflect total muscle mass in an adolescent?

• A. Height in inches or centimeters.
• B. Weight in kilograms or pounds.
• C. Triceps skinfold thickness.
• D. Upper arm circumference.

Correct answer: D

Rationale: The correct answer is 'Upper arm circumference.' Upper arm circumference is a better indicator of total muscle mass in adolescents compared to height, weight, or triceps skinfold thickness. Triceps skinfold thickness primarily reflects subcutaneous fat, while weight and height are not specific to muscle mass. Upper arm circumference directly measures the muscle mass in the upper arm and can provide a more accurate assessment in this context. Therefore, choices A, B, and C are incorrect because they do not directly reflect total muscle mass in adolescents.

2. A client with chronic kidney disease is receiving epoetin alfa (Epogen). Which laboratory value should the LPN/LVN monitor to determine the effectiveness of this medication?

• A. Serum potassium
• B. Hemoglobin
• C. Serum creatinine
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: The correct answer is B: Hemoglobin. Monitoring hemoglobin levels is essential to assess the effectiveness of epoetin alfa in clients with chronic kidney disease. Epoetin alfa is a medication that stimulates red blood cell production, aiming to increase hemoglobin levels and improve symptoms of anemia in these patients. Monitoring serum potassium (Choice A) is important in clients with kidney disease, but it is more related to assessing electrolyte balance rather than the direct effectiveness of epoetin alfa. Serum creatinine (Choice C) and blood urea nitrogen (Choice D) are kidney function tests that help evaluate kidney health but do not specifically reflect the effectiveness of epoetin alfa therapy.

3. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?

• A. Assess the client for a gag reflex
• B. Measure the pH of the gastric aspirate
• C. Place the end of the NG tube in water to observe for bubbling
• D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water

Correct answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

4. A home health nurse is discussing the dangers of carbon monoxide poisoning with a client. Which of the following information should the nurse include?

• A. Carbon monoxide does not have a distinct odor.
• B. Water heaters should be inspected every 5 years.
• C. The lungs are not damaged from carbon monoxide inhalation.
• D. Carbon monoxide binds with hemoglobin in the body.

Correct answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.

5. A client has right-sided paralysis following a cerebrovascular accident. Which of the following prescriptions should the nurse anticipate to prevent a plantar flexion contracture of the affected extremity?

• A. Ankle-foot orthotic
• B. Continuous passive motion machine
• C. Abduction splint
• D. Sequential compression device

Correct answer: A

Rationale: An ankle-foot orthotic is the correct choice to prevent a plantar flexion contracture in a paralyzed limb. An ankle-foot orthotic helps maintain proper alignment of the foot and ankle, preventing the foot from being permanently fixed in a pointed-down position. Continuous passive motion machines are typically used to promote joint movement after surgery and would not address the prevention of contractures in this case. Abduction splints are used to keep the legs apart and would not address the specific issue described. Sequential compression devices are used to prevent deep vein thrombosis by promoting circulation in the lower extremities and are not indicated for preventing plantar flexion contractures.
