Question 1 of 5

Which explanation to the client by the nurse regarding the use of antibiotics is best?

A. Use a sterile tube each time and suction for 30 seconds B. Use sterile technique and turn the suction off as the catheter is introduced C. Use clean technique and suction for 10 seconds D. Discard the catheter at the end of every shift

Question 3 of 5

A farmer who has had a cough for several months has noticed a lack of energy lately. He is being tested for histoplasmosis. Which factor reported by the client would be most related to the diagnosis of histoplasmosis?

A. He drinks raw milk. B. He cleans chicken houses. C. He handles fertilizer frequently. D. He stepped on a rusty nail recently.

Question 4 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 5 of 5

Which question is essential for the nurse to ask before administering the influenza vaccine?

A. Have you had influenza in the last year? B. Did you receive pneumonia vaccine last year? C. Are you allergic to eggs or egg products? D. Do you have a history of respiratory disease?

Correct Answer: C

Rationale: Influenza vaccines are often produced using eggs, so an egg allergy must be assessed to prevent allergic reactions.
