Nursing Elites

1. Based on this strip, what is the interpretation of this rhythm?

• A. Atrial fibrillation.
• B. Ventricular tachycardia.
• C. Normal sinus rhythm.
• D. Second-degree heart block.

Correct answer: C

Rationale: The correct answer is C, Normal sinus rhythm. Normal sinus rhythm is characterized by a regular rhythm, normal P waves, and a consistent PR interval. In this context, the strip likely shows a normal ECG pattern with these characteristics, indicating a healthy heart rhythm. Choices A, B, and D are incorrect. Atrial fibrillation would show an irregularly irregular rhythm with no discernible P waves. Ventricular tachycardia would display wide QRS complexes and a fast heart rate. Second-degree heart block would exhibit intermittent dropped QRS complexes.

2. The client with osteoporosis is being taught about dietary modifications by the nurse. Which food should the nurse recommend to increase calcium intake?

• A. Broccoli
• B. Chicken breast
• C. White bread
• D. Apple

Correct answer: A

Rationale: Broccoli is the correct answer as it is a good source of calcium, which is essential for clients with osteoporosis. Broccoli is a green leafy vegetable that provides a significant amount of calcium. Chicken breast, white bread, and apple do not contain as much calcium as broccoli and therefore are not the best choices to recommend for increasing calcium intake in clients with osteoporosis.

3. What assessment findings should lead the nurse to suspect Down syndrome in a newborn?

• A. Hypertonia and dark skin
• B. Low-set ears and a simian crease
• C. Inner epicanthal folds and a high, domed forehead
• D. Long, thin fingers and excessive hair

Correct answer: B

Rationale: The correct answer is B: 'Low-set ears and a simian crease.' These are key physical characteristics commonly seen in newborns with Down syndrome. Low-set ears, along with a simian crease (a single palmar crease), are indicative of Down syndrome. Choices A, C, and D are incorrect because hypertonia, dark skin, inner epicanthal folds, a high, domed forehead, long, thin fingers, and excessive hair are not specific features associated with Down syndrome in newborns. Therefore, the presence of low-set ears and a simian crease should raise suspicion for Down syndrome and prompt further evaluation.

4. What could suddenly occur in a child with acute epiglottitis?

• A. Increased carbon dioxide levels
• B. Airway obstruction
• C. Inability to swallow
• D. Bronchial collapse

Correct answer: B

Rationale: In acute epiglottitis, the infected epiglottis becomes inflamed and can lead to sudden airway obstruction, which is a life-threatening emergency. This can cause difficulty breathing and necessitates immediate intervention to secure the airway. Increased carbon dioxide levels may occur due to inadequate ventilation resulting from airway obstruction, but the primary concern is the obstruction itself, not the carbon dioxide levels. Inability to swallow may be present due to pain and swelling in the throat but is not the immediate life-threatening complication associated with acute epiglottitis. Bronchial collapse is not a typical consequence of acute epiglottitis.

5. The mother of a child who has been diagnosed with varicella asks the nurse when the child can return to school. When is the child no longer contagious?

• A. When the fever dissipates
• B. After the incubation period
• C. When the lesions have healed
• D. When the lesions are crusted over

Correct answer: D

Rationale: The correct answer is D: 'When the lesions are crusted over.' Varicella is no longer contagious once the lesions are dry and crusted. This stage indicates that the active viral shedding has significantly decreased, reducing the risk of transmission. Choice A, 'When the fever dissipates,' is incorrect because the presence of fever does not necessarily correlate with the contagiousness of varicella. Choice B, 'After the incubation period,' is incorrect as the incubation period occurs before the onset of symptoms and is not relevant to determining contagiousness. Choice C, 'When the lesions have healed,' is incorrect as healed lesions can still be contagious if they are not crusted over.
