A nurse is preparing to teach the parents of a child who has cystic fibrosis. Which of the following instructions should the nurse plan to include?

Trim the fat from red meat prior to cooking.

Provide a diet high in protein and calories.

Administer pancreatic enzymes 30 min after meals.

Give the child hot foods to reduce the sense of fullness.

Answer and Explanation

The Correct Answer is B

A. Trim the fat from red meat prior to cooking. Children with cystic fibrosis often have difficulty absorbing fats due to pancreatic insufficiency, but they actually need higher fat intake to meet their increased energy demands. Trimming fat is not necessary or recommended.
B. Provide a diet high in protein and calories. Children with cystic fibrosis require a high-calorie, high-protein diet to support growth, maintain weight, and compensate for the energy lost due to chronic lung infections and malabsorption.
C. Administer pancreatic enzymes 30 min after meals. Pancreatic enzymes should be given before or with meals and snacks to aid digestion. Giving them 30 minutes after a meal reduces their effectiveness.
D. Give the child hot foods to reduce the sense of fullness. There is no evidence to support using hot foods to manage fullness in cystic fibrosis. Instead, meals should be nutrient-dense and timed to optimize digestion and absorption.

Correct Answer is C,B,A,D

Explanation

C. Lubricate the catheter with sterile saline. After donning sterile gloves, the nurse should lubricate the catheter to reduce friction and prevent trauma to the tracheal mucosa during insertion.

B. Insert the catheter until resistance is felt. The catheter should be gently inserted into the tracheostomy until resistance is met, indicating that it has reached the carina. Inserting beyond this point may cause injury.

A. Withdraw the catheter 1 to 2 cm (0.4 to 0.8 in). Pulling back slightly after resistance ensures the catheter is not pressing directly on sensitive structures and is positioned correctly for effective suctioning.

D. Rotate the catheter while suctioning. Suction should be applied while withdrawing the catheter in a rotating motion to evenly clear secretions and minimize damage to the tracheal lining.

A. Fever B. Exudate on pharynx C. Wheezing upon auscultation D. Drooling E. Hypoxia F. Tachypnea

Correct Answer is {"A":{"answers":"A,B"},"B":{"answers":"C"},"C":{"answers":"B"},"D":{"answers":"A"},"E":{"answers":"A,B"},"F":{"answers":"A,B"}}

Explanation

Fever: Fever is a nonspecific but common symptom found in all three conditions—epiglottitis, RSV, and streptococcal pharyngitis. However, it is more severe and abrupt in epiglottitis and low to moderate in RSV and strep throat. In this case, the toddler has had a persistent fever over 38°C, consistent with both RSV and strep.
Exudate on pharynx: Pharyngeal exudate is a hallmark sign of acute streptococcal pharyngitis, resulting from the inflammatory response to GABHS. It is not typical in RSV or epiglottitis, where erythema and swelling may occur but without purulent exudate.
Wheezing upon auscultation: Wheezing is a classic sign of RSV, a lower respiratory viral infection leading to bronchiolitis and airway obstruction. It is not a feature of epiglottitis or strep throat, which involve the upper airway and oropharynx, respectively.
Drooling: Drooling is strongly associated with epiglottitis, due to inflammation and swelling of the epiglottis which makes it painful and difficult to swallow. It is not typical in RSV or strep pharyngitis unless there is severe oral involvement or dehydration.
Hypoxia: Hypoxia may occur in both epiglottitis and RSV due to airway obstruction or inflammation compromising oxygenation. In epiglottitis, it results from upper airway narrowing; in RSV, from lower airway inflammation and mucus plugging. It is not common in uncomplicated streptococcal pharyngitis.
Tachypnea: Tachypnea is a sign of respiratory distress and is often present in both epiglottitis and RSV, as the body attempts to compensate for impaired gas exchange. It is not a primary feature of strep pharyngitis unless accompanied by systemic infection or high fever.
