A child has had cold symptoms for more than 2 weeks, a headache, nasal congestion with purulent nasal drainage, facial tenderness, and a cough that increases during sleep. The nurse recognizes that these symptoms are characteristic of which respiratory condition?

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.

A. Fat-soluble vitamins:Children with cystic fibrosis often require supplementation with fat-soluble vitamins (A, D, E, and K) due to impaired fat absorption. However, these alone do not facilitate digestion; they are supplemental and secondary to enzyme therapy.

B. Pancreatic enzymes:Pancreatic enzymes are essential for children with cystic fibrosis because thick mucus blocks pancreatic ducts, preventing digestive enzymes from reaching the intestines. Administering these enzymes with meals promotes the digestion and absorption of fats, proteins, and carbohydrates.

C. Water-soluble minerals:Water-soluble minerals like magnesium or zinc may be needed in some cases, but they do not directly improve digestion or address malabsorption in cystic fibrosis. They are not the primary intervention.

D. Salt supplements:Salt supplements are often needed due to excessive sodium loss in sweat, especially in hot climates or during exercise. However, they help with electrolyte balance, not digestion or nutrient absorption.
