Question 1 of 5

If the client identifies that lunches often include the following foods, which meal is the most nutritious?

Correct Answer: C

Rationale: Meatless chili with beans, corn bread, and milk provides protein, carbohydrates, and calcium, making it the most balanced and nutritious option.

Question 2 of 5

The nurse is presenting a class on chest tubes. Which statement best describes a tension pneumothorax?

A. A tension pneumothorax develops when an air-filled bleb on the surface of the lung ruptures. B. When a tension pneumothorax occurs, the air moves freely between the pleural space and the atmosphere. C. The injury allows air into the pleural space but prevents it from escaping from the pleural space. D. A tension pneumothorax results from a puncture of the pleura during a central line placement.

Correct Answer: C

Rationale: Tension pneumothorax traps air in the pleural space (
C), increasing pressure. Bleb rupture (
A) causes simple pneumothorax, free air movement (
B) is open pneumothorax, and central line (
D) is a cause, not definition.

Question 3 of 5

Which of the following are typical signs and symptoms of pneumonia? Select-all-that-apply:

A. Stridor B. Coarse crackles C. Oxygen saturation less than $90 \%$ D. Non-productive, nagging cough E. Elevated white blood cells F. Low PCO2 of less than 35 G. Tachypnea

Correct Answer: B,C,E,G

Rationale: Pneumonia typically presents with coarse crackles due to fluid in alveoli, low oxygen saturation from impaired gas exchange, elevated WBCs indicating infection, and tachypnea (G) as a compensatory mechanism. Stridor is associated with upper airway obstruction, non-productive cough is less common, and low PCO2 suggests hyperventilation, not typical.

Question 4 of 5

A patient is presenting with mild symptoms of pneumonia. The doctor diagnoses the patient with 'walking pneumonia'. From your nursing knowledge, you know this type of pneumonia is caused by what type of infectious agent?

A. Fungi B. Streptococcus pneumoniae C. Mycoplasma pneumoniae D. Influenza

Correct Answer: C

Rationale: Walking pneumonia is commonly caused by Mycoplasma pneumoniae, a bacterium that leads to mild, community-acquired pneumonia. Fungi cause fungal pneumonia, Streptococcus pneumoniae causes typical bacterial pneumonia, and Influenza is a viral infection.

Question 5 of 5

The nurse is taking the social history from a client diagnosed with small cell carcinoma of the lung. Which information is significant for this disease?

A. The client worked with asbestos for a short time many years ago. B. The client has no family history for this type of lung cancer. C. The client has numerous tattoos covering both upper and lower arms. D. The client has smoked two (2) packs of cigarettes a day for 20 years.

Correct Answer: D

Rationale: Smoking (
D) (40 pack-years) is the primary risk factor for small cell lung cancer. Asbestos (
A) is a risk but less significant, family history (
B) is irrelevant, and tattoos (
C) are unrelated.
