Nursing Elites

1. A healthcare professional is caring for a client who has pharyngeal diphtheria. Which of the following types of transmission precautions should the healthcare professional initiate?

• A. Contact
• B. Droplet
• C. Airborne
• D. Protective

Correct answer: B

Rationale: The correct answer is B: Droplet. Droplet precautions are required for infections that spread via droplets larger than 5 microns in diameter, such as pharyngeal diphtheria. Contact precautions are used for diseases that spread by direct or indirect contact. Airborne precautions are for diseases that spread through small particles in the air. Protective precautions are not a standard precautionary measure for specific infections like pharyngeal diphtheria.

2. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Blood urea nitrogen (BUN) of 45 mg/dL
• C. Serum potassium of 6.5 mEq/L
• D. Hemoglobin of 10 g/dL

Correct answer: C

Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.

3. The caregiver is teaching parents about the diet for a 4-month-old infant with gastroenteritis and mild dehydration. In addition to oral rehydration fluids, the diet should include

• A. Formula or breast milk
• B. Broth and tea
• C. Rice cereal and apple juice
• D. Gelatin and ginger ale

Correct answer: A

Rationale: The correct answer is A: Formula or breast milk. In infants with gastroenteritis and mild dehydration, it is essential to continue feeding them with formula or breast milk along with oral rehydration fluids to provide adequate nutrition and maintain hydration. Option B, broth and tea, may not provide the necessary nutrients and electrolytes needed for the infant's recovery. Option C, rice cereal and apple juice, can be harsh on the digestive system and may exacerbate diarrhea. Option D, gelatin and ginger ale, do not provide the necessary nutrients and can worsen the condition due to the high sugar content in ginger ale.

4. A nurse on a medical-surgical unit is washing her hands prior to assisting with a surgical procedure. Which of the following actions by the nurse demonstrates proper surgical hand-washing techniques?

• A. The nurse washes with her hands held higher than her elbows.
• B. The nurse uses a brush to scrub under her nails.
• C. The nurse washes for at least 30 seconds.
• D. The nurse uses alcohol-based hand rub only.

Correct answer: A

Rationale: Proper surgical hand-washing technique involves keeping the hands higher than the elbows to prevent contamination. Washing with hands held lower than the elbows can lead to potential contamination. Using a brush to scrub under the nails is not recommended as it can cause microabrasions, increasing infection risk. While washing for at least 30 seconds is a good practice for thorough hand hygiene, hand positioning is critical during surgical hand-washing. Using alcohol-based hand rub alone is insufficient for surgical hand-washing as it may not effectively remove dirt, debris, and transient microorganisms.

5. 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.
