Questions
QUESTION 1 OF 55
What is a pancreatic enzyme used for?
Correct Answer: - prevent pancreatic insufficiency in cystic fibrosis patients
- should be taken with each meal and snack given
Rationale: Pancreatic enzymes are crucial for individuals with pancreatic insufficiency, particularly in cystic fibrosis
patients, as they aid in the digestion and absorption of nutrients that the body cannot adequately process due to
insufficient enzyme production. Taking these enzymes with each meal and snack ensures that they are present during
digestion, maximizing their effectiveness in breaking down fats, proteins, and carbohydrates. This administration
timing helps to mitigate malnutrition and improve health outcomes for these patients. This aligns with - prevent
pancreatic insufficiency in cystic fibrosis patients and - should be taken with each meal and snack given.
QUESTION 2 OF 55
Ear drop administration
Correct Answer: - 0 to 3 years olds: pull pinna down and back
- 3 and up: pull pinna up and back
Rationale: The administration of ear drops requires specific techniques based on the age of the patient due to the
anatomical differences in the ear canal. For children aged 0 to 3 years, pulling the pinna down and back aligns the ear
canal in a way that facilitates the effective delivery of the medication, as their ear canals are shorter and positioned
differently. In children aged 3 years and older, pulling the pinna up and back straightens the ear canal for better
access, as their anatomy begins to resemble that of adults. This age-specific approach ensures that the drops reach the
tympanic membrane effectively, maximizing the treatment's efficacy. This aligns with - 0 to 3 years olds: pull pinna
down and back and - 3 and up: pull pinna up and back.

, QUESTION 3 OF 55
bacterial pneumonia s/s
Correct Answer: - high fever, cough, tachypnea, retractions, nasal flaring, chest pain, chest dullness with
percussion
Rationale: Bacterial pneumonia typically presents with high fever due to the inflammatory response to infection,
alongside a productive cough that helps clear the respiratory tract. Tachypnea indicates increased respiratory effort,
often accompanied by retractions and nasal flaring, which are signs of respiratory distress as the body attempts to
improve oxygenation. Chest pain may arise from pleuritic irritation, while dullness on percussion suggests the
presence of fluid or consolidation in the lung, reflecting the underlying pathology of the infection. Each of these signs
and symptoms is indicative of the body's response to bacterial infection in the lungs, making them characteristic
features of bacterial pneumonia. This aligns with chest dullness with percussion, - high fever and chest pain.
QUESTION 4 OF 55
Diagnostic procedures for asthma
Correct Answer: - PFT, peak expiratory flow, exercise challenges
- CBC: increased WBC, eosinophils
Rationale: Pulmonary function tests (PFT) are essential for assessing lung function and identifying the degree of
airway obstruction characteristic of asthma. Peak expiratory flow measurements provide a quick assessment of the
patient's ability to exhale air, indicating variability in airway obstruction. Exercise challenges can provoke asthma
symptoms, helping to confirm the diagnosis in patients with exercise-induced bronchoconstriction. A complete blood
count (CBC) may show increased white blood cells and eosinophils, indicating an inflammatory response often seen in
asthma, particularly in allergic or eosinophilic asthma. This aligns with peak expiratory flow, - CBC: increased WBC
and exercise challenges.
QUESTION 5 OF 55
risk factors for otitis media with effusion
Correct Answer: - children who attend daycare, and children who are passively exposed to cigarette
smoke, allergies, enlarged adenoids
- blocked eustachian tube(s), viral or bacterial infection
Rationale: The risk factors for otitis media with effusion include environmental and anatomical influences that can
lead to dysfunction of the Eustachian tubes and increased susceptibility to infections. Children who attend daycare are
at higher risk due to increased exposure to infectious agents, while passive exposure to cigarette smoke can lead to
inflammation and blockage of the Eustachian tubes. Allergies and enlarged adenoids can also contribute to Eustachian
tube obstruction, further predisposing children to fluid accumulation in the middle ear. Additionally, existing viral or
bacterial infections can exacerbate these conditions, leading to otitis media with effusion. This aligns with and children
who are passively exposed to cigarette smoke, - children who attend daycare and - blocked eustachian tube(s).
