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. The nurse is providing discharge teaching to a client who has been prescribed digoxin (Lanoxin). Which statement by the client indicates a need for further teaching?

• A. I should take my pulse before taking the medication.
• B. I will take my medication at the same time every day.
• C. I should avoid taking antacids at the same time as this medication.
• D. I should eat foods high in potassium while taking this medication.

Correct answer: D

Rationale: The correct answer is D. Eating foods high in potassium can lead to hyperkalemia when taken with digoxin, indicating a need for further teaching. Choices A, B, and C are all correct statements that demonstrate understanding of digoxin therapy. Taking the pulse, maintaining a consistent dosing schedule, and avoiding antacids to prevent interactions with digoxin are all appropriate client responses.

3. The healthcare provider is caring for a client who has just been diagnosed with myasthenia gravis. Which symptom should the healthcare provider expect to observe?

• A. Muscle weakness
• B. Joint pain
• C. Vision changes
• D. Skin rash

Correct answer: A

Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).

4. In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to

• A. Stabilize alveolar surface tension
• B. Maintain alveolar surface tension
• C. Promote normal pulmonary blood flow
• D. Regulate intra-cardiac pressure

Correct answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.

5. When should the client administer the inhaler-delivered medication to demonstrate correct use of the inhaler?

• A. Immediately after exhalation.
• B. During the inhalation.
• C. At the end of three inhalations.
• D. Immediately after inhalation.

Correct answer: B

Rationale: The correct answer is B: 'During the inhalation.' Administering the medication while inhaling ensures proper delivery to the lungs. Inhaling the medication allows it to reach the lungs effectively for optimal therapeutic benefit. Choices A, C, and D are incorrect because administering the medication after exhalation or at the end of inhalations may result in improper drug delivery and reduced therapeutic effects.
