The nurse is caring for a patient with pneumonia. Which laboratory test would best help the nurse to monitor the condition of this patient?
White blood cell (WBC) count, arterial blood gases (ABGs)
Complete blood count (CBC), urinalysis
Electrolytes, serum creatinine
Partial thromboplastin time (PTT), serum potassium
The Correct Answer is A
A. White blood cell (WBC) count, arterial blood gases (ABGs): WBC count helps assess the presence and severity of infection, while ABGs evaluate the patient’s oxygenation and gas exchange critical factors in pneumonia. These tests directly reflect respiratory function and the inflammatory response.
B. Complete blood count (CBC), urinalysis: While a CBC includes the WBC count, the rest of the values are not directly helpful in tracking pneumonia progression. A urinalysis assesses kidney and urinary tract health, not respiratory infection, so it is not essential.
C. Electrolytes, serum creatinine: These tests provide information on renal function and electrolyte balance, which may be relevant in complex cases but are not specific indicators of pneumonia status or treatment response.
D. Partial thromboplastin time (PTT), serum potassium: PTT evaluates clotting, and serum potassium assesses electrolyte balance. Neither test provides useful information about the progression or resolution of pneumonia.

= 4 capsules.
Correct Answer is C
Explanation
A. "It will reduce the frequency of your cough. Antitussives suppress the cough reflex and may reduce how often the patient coughs. However, this answer is vague and does not address the patient's concern and doesn't provide specific guidance on usage.
B. "It should be used in the morning." Antitussives are not recommended for use in the morning unless the cough is disruptive to daytime function. Taking them in the morning could lead to daytime drowsiness, if the medication contains sedating agents like codeine.
C. "It should be taken before sleep." This is the best response because antitussives are often most beneficial at night when coughing can disrupt sleep. Administering them before bed helps reduce nocturnal coughing and supports rest, which is essential for recovery.
D. "It will eliminate your cough at night." While antitussives may greatly reduce coughing, they do not guarantee total elimination of the cough. This statement creates unrealistic expectations and may mislead the patient regarding the effectiveness of the medication.
