A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a "trigger" results in which of these manifestations?
- A. Bronchodilation, muscle relaxation, and decreased mucus production
- B. Air trapping and hypo-inflation of the alveoli
- C. Air trapping and decreased blood flow to the upper airway
- D. Bronchoconstriction, airway inflammation, and excess mucus production
Correct Answer: D
Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.

A child is admitted in acute renal failure (ARF). Therapeutic management to rapidly provoke a flow of urine includes the administration of what medication?
- A. Propranolol (Inderal)
- B. Calcium gluconate
- C. Mannitol (Osmitrol) or furosemide (Lasix)
- D. Sodium, chloride, and potassium
Correct Answer: C
Rationale: Mannitol and furosemide are diuretics commonly used to induce diuresis in acute renal failure, helping to provoke urine flow and manage fluid overload. Calcium gluconate and electrolyte supplementation are used for other specific conditions and not primarily for diuresis.
What is the narrowing of the preputial opening of the foreskin called?
- A. Chordee
- B. Phimosis
- C. Epispadias
- D. Hypospadias
Correct Answer: B
Rationale: Phimosis is the condition where the foreskin cannot be fully retracted over the glans penis due to a narrowing of the preputial opening. Chordee, epispadias, and hypospadias are different conditions involving the penis's structure.
According to Erikson's developmental theory, toddlers need to be encouraged to become independent to successfully complete which developmental challenge?
- A. Trust vs. mistrust
- B. Industry vs. inferiority
- C. Autonomy vs. shame and doubt
- D. Initiative vs. guilt
Correct Answer: C
Rationale: The correct answer is C: Autonomy vs. shame and doubt. Erikson's developmental stage for toddlers focuses on the conflict between developing a sense of independence (autonomy) and feelings of inadequacy (shame and doubt). Encouraging toddlers to explore their environment and make choices helps them build self-confidence and independence. Choices A, B, and D are incorrect because trust vs. mistrust relates to infancy, industry vs. inferiority is associated with school-age children, and initiative vs. guilt is linked to preschoolers.
What recommendation should the nurse make to prevent urinary tract infections (UTIs) in young girls?
- A. Avoid public toilet facilities
- B. Limit long baths as much as possible
- C. Cleanse the perineum with water after voiding
- D. Ensure clear liquid intake of 2 L/day
Correct Answer: C
Rationale: Proper perineal hygiene, including cleansing with water after voiding, is crucial in preventing UTIs in young girls. Avoiding public toilets and limiting baths are less effective than proper hygiene practices.
What findings on physical assessment of a neonate would indicate the need for further evaluation?
- A. Nystagmus
- B. Epstein pearls
- C. Low-set ears
- D. Positive Babinski reflex
Correct Answer: C
Rationale: Low-set ears in a neonate suggest major abnormalities and should prompt further evaluation. The correct alignment of the top of the pinnae of the ear with the outer canthus of the eye is crucial. Nystagmus, an involuntary eye movement, is common in newborns and often resolves on its own. Epstein pearls, small cysts on the hard palate, are insignificant and disappear over time. A positive Babinski reflex is normal in infants up to 1 year of age. Therefore, the presence of low-set ears is the most concerning finding that requires immediate attention.
